Computer Causing Router To Reset
Aug 31, 2011
If my computer has been sitting for a while without using the internet and i open my browser the dsl and internet lights on my router shut off for about 15 seconds and no one in my house has internet and then it turns back on. this ONLY happens when it has been sitting for a while with the browser closed and my computer is the only one that makes it do it. also i don't have my computer set to sleep after a certain time, my monitor turns off after 5 minutes and that's it. i have a siemens gigaset se567 and my isp is telus.

I set up an E1200 about two weeks ago to replace our old DI-524 because our net speeds were getting throttled (the old router wouldn't support anything higher than 10mbps). The same day, we started getting modem resets (We have an SB6120). This never happened on the old router but it's constantly happening with this new one. It'll happen multiple times a day. I called Cox Tech Support and they pushed an upgrade onto the modem but it still reset. I don't think it's the router, since I don't understand why it would force the modem to reset, but this never happened before I installed it. The firmware is updated to the latest version on the Cisco site (1.0.02).

My new HP Touchpad 32 GB is causing my E4200 to reset. I can duplicate the issue by simply access the HP App Catalogue. I upgraded the firmware from 1.01 to 1.03 build 13 and the issue still exists.

I have 2 laptops and 1 desktop all connected to the same router, the 2 laptops are connected via wifi and the desktop PC is currently connected via an Ethernet cable, both laptops run windows 7 while the desktop runs windows XP and more or less every time the desktop is booted after a few minutes of normality connection to the internet is lost and the yellow triangle on windows 7 appears so to fix this I have to go into my routers settings via 192.168.1.1 and reboot which then solves the problem and all machines function as they should including the desktop.

Basically, my issue stems from the latest Boxee firmware from 2 weeks ago, that since then, its been causing my DIR 655 to reset itself, thereby disabling my whole home internet. It eventually turns back on again after a while, but the process doesn't stop.Basically, my DIR 655 is connected, hard wired to my boxee. I also have a NAS 323 hard wired to my router. I've had this setup on my boxee, reading all my movies/shows from my NAS without any issues for the past 10 months. Then the firmware from 2 weeks ago on the boxee started to cause my router to reset. I thought it was a hardware router failure, so I bought another of the same model to try that out, same thing happened though. When I rolled back my boxee firmware to the previous version, it no longer causes my router to reset.Now, besides me trying to figure out how to correctly block the boxee from updating on the router. Is there anything I can do on the router to tell it to prevent it from letting the boxee forcing it to reset? I'm on High Speed DSL. My internet provider modem is acting as a bridge to my DIR 655. Its been working fine for the past 10 months.
I've also done the following:Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find thse under Status/Device Info/Wan section. Turned off ALL QoS Turned off Advanced DNS Services if you have this option under Setup/Internet/Manual.Turned on DNS Relay under Setup/Networking.Setup DHCP reserved IP addresses for all devices on my router.Ensure devices are set to auto obtain an IP address.I have Set Firewall settings to Endpoint Independent for TCP and UDP..
Basically, I've put my boxee back to my previous firmware, and this doesn't cause my router to reset and disable my internet. But I don't get how/why a firmware update can trigger my router to do this?

After recently setting up a new computer, my entire network seems to randomly loose internet connection. The interval between connection losses is as short as half an hour but it sometimes goes several hours without dying; the connections is lost for anywhere between 30 seconds and 20 minutes each time it dies.The new computer is running Windows 7 and is using a Roeswill USB wireless adapter, but I have tired it with a wire and the connection still dies. I am disinclined to believe that this is caused by a virus simply because this is a brand new computer that has had only minimal use; to be on the safe side, though, I did do virus scans with multiple programs, however, I did not find anything.When the connection is lost, a yellow exclamation appears on the task bar's internet access icon. If I check my available networks, my network still shows full strength. I have tried disconnecting and reconnecting but nothing happens; I don't get any "failure to connect" type errors nor do I get connection back. I have also tried physically removing the adapter/wire and plugging it back in, but that doesn't do anything either.
I am under the impression that the new Windows 7 computer is doing something to temporarily kill the entire network, but I don't know what.For the record, my modem is an old Motorola and my router is an old Netgear. Both are quite a few years old, but I don't think they are the problem as my internet was fine before I added the new Windows 7 computer. There are wired computers and wireless computers running XP, Vista, and 7 also on the network.

I have 2 computers on a network, and 3 devices that use wifi on the same network. Basically when ever computer A is connected, every single computer or device on the network runs extremely slow, if at all. I get anywhere between 1200-2000 ping on pingtest with 2-60% packet loss. Even the speed on the "infected" computer A downloads extremely slow. I'm at a loss for this problem, everything runs slow and its because of the one computer connected to it. I have virus software on this computer, but its not the best so i'm not ruling out malware or viruses right off the bat.
Devices: Blackberry, Iphone, macbook (all wifi)
Computer A
Runs windows xp 32 bit,
amd processor
onboard video
[code].....
The internet modem runs to a router (Dlink dir615) then to a switch (or hub, if you will) and then to the 2 computers. The entire problem is solved by unplugging computer A from the system. But other than that I have no alternative.

Recently me and my girlfriend have been having issues with in game latency, receiving pings close to jittering to well over 300 where they were formerly in the 30-40s to identical servers. We live with a Chinese housemate who is extremely conscious of her privacy/personal space, we noticed a dirge of active ports on the router (both TCP and UDP) which seemed to have no association with any major application and assumed it was the old P2P boogie-monster. She is the only one who uses Wifi, an upon briefly deactivating the Wifi, all ping issues were instantly resolved. The bizarre thing is we still have plently of up/download bandwidth, I mean we're not swimming in a fibre optic connection but still a relatively healthy 1MB dl/70KB/s ul, more than enough for gaming.Deciding we needed a better idea of what was going on in the network, we downloaded Wireshark. We discovered a couple of things that might mean something, they might mean nothing at all:Firstly there was a deluge of random ARP requests coming from the suspect IP, something along the lines of:"who has 192.168.0.(random number) Tell (suspect computer's IP)"repeated over and over in bursts. A little googling found us this: Has Your Network been Now given that she is Chinese and is probably exposed to a lot of Chinese websites, is there any chance that this could be the root cause - could it drown the network to the extent that it produces terrible pings?Secondly there have been an inordinate amount of name queries coming from her IP to 192.168.0.255 (broadcast channel), they generally take the form of:
NBNS92Name query NB WPAD<00>
or
NBNS92Name query NB ISATAP<00>
and occasionally, it will name query my network id, leading to: (her ip being 192.168.0.3)
2144211275.734470000192.168.0.3 192.168.0.255NBNS92Name query NB (my id)<20>
2144231275.739314000192.168.0.3 (my id)TCP6658451 > netbios-ssn [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=4 SACK_PERM=1
2144251275.741325000192.168.0.3 (my id)NBSS126Session request, to (my network id)<20> from (her network id)<00>
2144271275.744124000192.168.0.3 (my id)SMB213Negotiate Protocol Request
[code]....
Now combine this with the sometimes 9-10 active ports our router assigns to her IP (which don't appear to relate to anything according to numerous port id sites), does this send out a red flag to any of you? I realize it would be so much easier if I could get access to her computer, but as I said, she is very private and timid and doesn't seem to like even having people in her room, let alone letting them use her computer.

I recently bought a new laptop (Asus U47VC) and i am having internet connection issues. When I am at my mother's place or at school, I have no problem connecting to the internet wirelessly. However, at my father's place, my internet stops working every couple hours and will be unable to connect to the network until i reset the router and modem. Once the reset is complete, I am good for another couple hours. All the other devices ( laptops, iphones, etc.) do not have this problem and the connection is never an issue. I have read that this could possibly be a problem regarding IP addresses but I do not quite understand how to fix this.

I have a dlink(wireless n-300) router going through a netgear wireless g router, i have an intel wifi link 5100 agn in my acer aspire 6930g laptop & the isp is high speed cable (Shaw cable). My question is, why does my computer have to reset the router every minute or so? It takes forever to get anything on the web which could be Bitdefender 2012 plus security?

I started my PC (aser) as usuao but did not connect to internet that i am using TP Link modem/router, I turned laptop on and get conected the wireless is working fine, serached about TP links solutions and applied all of them, before I was using "obtain IP automatically" then I used to insert the required IPs manually, applied and save and restarted several times... still cannot connect to the internet while I still connected to the same modem+router via laptop wireless connection,
Finally I decided to format and installed new OS XP, though some wrong error was with my OS, unfortunately even after installing new OS still not able to connect, I checked the IP and tried both options and still cant access, i never experienced such..

I'll access a site like [URL] normally the first 2 or three links will work that I click on and then maybe the third link will cause a timeout. I'll refresh the page after receiving the timeout notice and it'll appear fine. This is happening to other sites aswell. The reason I know it's the router is when I plug my PC directly into the modem, I don't receive this problem. The problem is happening with my laptop, PC and iphone. I've asked the ISP to go over the settings in my router to make sure they're all configured correctly and they say they're not trained on troubleshooting routers so they direct me to Netgear again. I don't really know what I should be looking at in the router page (I don't know much about routers/networking),

decided first of all to connect an old router to the master (but not test) socket together with different cabling & splitter/microfilter - everything starting working almost perfectly (apart from downstream data rate was considerably lower than expected each time I connected - between about 1400 & 1600 Kbps - I have max. 8 Mbps).when I connected back my current router everything continued to be OK (apart from low downstream data rate) - until I would restart the current router and everything went back to very very slow.

Since recently replacing my home router with a Linksys E2500, I have been getting Blue Screen of Death (BSOD) with my Company's VPN (AT&T). It only happens when I am running wireless with my E2500. If I am hooked up to my E2500 through a ethernet cable it doesn't happen. I have updated the BIOS on my Lenovo Thinkpad T410 and ensured all of my drivers are up to date. I am 99.9% sure the problem is caused by my Linksys E2500 because I have used my laptop on other wireless routes at work and school and never get this problem. I am also ensured that my E2500 has the current firmware installed and upgraded my Company's VPN to the most current level to no avail.
I am getting DRIVER_IRQL_NOT_LESS_OR_EQUAL Blue Screen of Death in agnfilt.sys.

For some reason, I have been trying to use QOS for several network related jobs (VPN, streaming). It would seem that when QOS is enabled and the appropriate ports are set which a high priority, the speed of my connection drops to a crawl. When I disable QOS, I'm flying again. I have confirmed ports, and protocol types (TCP or UDP) and nothing seems to work.

I just bought a Samsung BD-D5300 Blu-ray player that allows a bunch of networking options including wireless and wired. I was using the wired option when I came across some conflicts with my network using a Linksys WRT350N v1. The Samsung conflicted with the Linksys's DHCP server. The blu-ray player turns off automatically when inactive. It was causing conflicts with my iPad 2, MacBook Pro and Motorola Atrix android phone whenever it got assigned an IP address. When I reset the router and my cable modem, it wasn't assigned an address for awhile, which fixed things, but as soon as it got an address again, it was caused conflicts by being seen as a LAN by my router. When it wasn't receiving an address, it got the automatic private IP address of 169.x.x.x. When I removed the connection with my router, the conflicts disappeared and my computers were able to access my wifi again.

We have recently implemented some QoS on our routers and i have noticed that the CPU usage has risen enormously as a result.
I checked the CPU Processes and found that the avg values are 50% usage. This seems rather high considering that only 75% of our edge routers have this feature enabled.
Our main router is a Cisco CISCO2911/K9 (revision 1.0) with 487424K/36864K bytes of memory. Our edge routers are either 2801 models or 881 models.
This is our first implementation of QoS and would like to ensure that it is working properly before implementing other QoS rules. Here is a copy of the config on the 2911 router:
class-map match-all Citrix
match protocol citrix
class-map match-all Print
match protocol printer
class-map match-all C-Coolingata
[ code]......
Here is the config on our edge routers:
class-map match-any Citrix
match access-group name Citrix-ACL
[code]....
As you can see we have different link speeds at different sites based on their size, location etc. How to be able to confirm that this config is correct?

I've had an E4200v1 in use as my home's main router for about 3 mos. And while many others have reported disconnect problems (I think), I myself have never seen any. My router and its N & G wifi networks have been rock solid. Until yesterday that is.Now all of a sudden, most of my family is complaining about wifi disconnects, slow speeds, etc. (My primary PC is hard-wired so I don't see any problems whatsoever... the problem apears to be wifi-only)And the Apple devices (OSX & IOS) seem to have the most severe problems. But Windows devices have also seen problems, just not as critical.Also, it's worth noting that I've been running 1.0.04 the whole time, without any problems... it seemed relatively stable to me. That is until yesterday.
I've bounced the router, I've disabled/re-enabled Wireless G network. I've switched mode from "mixed" to "G-only" back to "mixed". I've changed the channel width back to the default of Auto (I had been using 20Mhz), which increased my throughput (as measured by Qcheck) so I'm leaving it "Auto".

I have an E1550 less than 1 year old. Lately, I have been losing internet on the AT&T modem. I called AT&T but as part of their diagnostics, I have to plug the modem directly into the PC. I have loaded the latest firmware to the E1550.Lose Internet but wireless connectivity to router exists.Internet light on modem is out (modem is connected to router)Unplug modem and leave off plug in, internet light is still out.Unplug router, plug router back in - no internet connection but do have wireless connectivity to router.Take cable from modem to router and plug directly into PC internet light comes on in modem and I have internet from PC.Take cable from PC and plug back into router .I have internet via wireless.What I can't figure out is what could be happening in router that would impact modem internet connection. I have replicated this at least 3 times. Yes, the modem is a bit old, but since plugging it directly into the PC works, I'm thinking it has to be the router and I cannot figure out why unless there's some sort of electrical thing going on in the router.

I work from home on a Lenovo Laptop. I connect to my work network, and ultimately to a midrange ISeries. For the past year I've had no major problems with my Netgear Linksys WRT54G. I switched to a Netgear N300 last weekend because my husband's desktop was having a lot of issues. His connection is much better now.I'm able to connect to the internet with no problem, and I can access my company network & email pretty well. But, when I log on the ISeries it slows to way less than a crawl. According to my netwok icon, the connection is anywhere from 104 to 130 MBPS at any given time. But it freezes up so badly that it takes about 20 - 30 seconds just to type each letter, or to go from one window to another, or just to move the cursor down one line. It's infuriating. Every once in awhile if I disconnect and reconnect it works almost normally for awhile, but eventually slows down almost to a stop again. I actually worked for about 90 minutes the other day with no problem before it started acting up again. When I put the old G router back it works fine again. My laptop has an Intel(R) Centrino(R) Advanced-N 620 wireless adaptor. As long as I don't connect to the iseries, I have good speed and no issues with the internet or work intranet.

I'm thinking of purchasing a Cisco Linksys EA6500. I need a router that can one monitor bandwidth used by device. Keep exceeding our ISP's network bandwidth allocation, need to identify the devices that are causing this high usage and be able to do so from the router. Does the EA6500's standard software support this, is their router software one can obtain for the unit that does this or is there another home router option that can perform this function?

I have a WiFi in my home, when this laptop is under normal load, say like streaming a 360p youtube video, all the computers in my home will experience a huge lag and it becomes impossible to surf or do any internet activity (even the causing laptop itself will experience huge pings). The weird part is that the lag is at the LAN level, it is not related to my internet bandwidth. Because when I ping my local router (192.168.2.1) with other PCs during the lag period, I get 1000-4000 ms. However, it is usually 1 ms. I tried doing a stress test on one of my normal laptops by downloading at maximum speed, the problem did not occur, there was no lag, all my PCs did not encounter that lag and I still get 1 ms when pinging the router. It is only this laptop that when it starts downloading, my network will be flooded.
Another related problem with the laptop is that every time I log off then log in and try to reconnect to my network, It will not allow me, I will have to click on the windows diagnose problem and it will be fixed saying "Problem with wireless adapter or access point".

I'm using cable (7.5Mbps) w/ unlimited bandwidth . I have 2 wired PC on the network and 4 PCs connected via wireless. My current router is a Netgear WND3400 but I had a Linksys WRT160n v3 previously.
My problem is that I've been getting very high ping in games (PC) and also on my PS3 like > 400ms over the past month but only after like 9:30pm or so. During the day it's always smooth. I called my ISP and they told me everything was fine from their end and the modem too.
1 PC on the network makes the other PCs lag even if that PC isn't downloading or using any bandwidth at all? I did some tests today, like: I open CMD and type: ping -t url... and I get like 6ms but when that particular PC is powered on, the ping increases to > 400ms.

For starters I have a qwest m1000 modem and a netgear router.this morning there was a rather large thundestorm that caused my power to cut out while I was usin my computer.. once I got it back up and running the ethernet light on my modem wasn't liighting up.I reallly have no idea what to do. Everything but the ethernet is working. I can still get to my routers website but that's it, and I don't what to do there once I'm on it.Is it possible the storm messed up the settings? Or killed part of my pc/modem? On my computer the ethernet light next to the jack on the back is yelllow when its threw my rouuter, but when I plug my modem into it directly it doesn't light up at all.

I've recently added a desktop pc to the home's wireless network (using a D-Link DWA-125 Wireless N 150 USB adapter rev.A2) and it used to play nicely with the other devices. After switching out the router to an Actiontec V1000H my computer has begun losing most connectivity when the PS3 is turned on.
The pc still sees the network and there is a little activity there it seems. Everything runs fine when the PS3 is off and in the Wireless Network Connection Status display the speed is usually listed at 65-75 Mbps. But when the PS3 is turned on it reads 6.5 Mbps with the IPv4 connectivity bouncing between "internet" and "limited". Windows' automatic diagnosis is "Cannot communicate with DNS server".
I tried assigning static IP addresses to the pc and ps3 thinking there was a possible IP conflict with the dynamic addresses. Thinking there could be a conflict with ports I read up on port forwarding but my knowledge of networking is limited and I'm not even sure if that is the problem.
There are alot of other devices connected, 2 laptops, 2 iPod touches an iPhone the PS3 and now this old desktop clunker. I figure it's possible that the router is getting overloaded with everything and the PS3 just pushes my computer's bandwidth out the window but I would think that there would be some noticable drop in performance on the other laptops as well, which there hasn't.

The process SNMP engine is the process that causes these spikes .We think that the job responsible of this periodic high CPU utilization. It's called "Vrf Collector Job" and it's runnning every 4 hours.Below the result of show stack PID and show version

I am dealing with three office networks, all three have the same conflict. The error messages I get all say there are two devices assigning ip addresses. As soon as I get the computers communicating with each other, two seem to crash overnight, I suspect due to the conflict. Here is the rundown on the networks. All are windows networks - the problem I am having is file sharing mostly and printing.
Network A: server OS is XP Pro - SP3, four workstations, XP Pro-SP3, Windstream DSL and Netgear Router. I have already bridged the router on this one, and it did not correct the conflict.
Network B: Server OS - Windows7 SP1, three workstations all XP Pro SP3, ISP is Clear (formerly clearwire). Router is the old wired Linksys befsr41 v4.
Network C: server OS - XP Pro SP2, ISP - Clear, three workstations - two are XP ProSP3 one is XP Pro SP2. I have had less trouble with this network, but I suspect the conflict exists here as well.
I have tried to get a static IP address from Windstream where I have had my worst problems, but cannot seem to get one. I suspect we have the least expensive service option possible, and are possibly using a service designed for home use as opposed to business, as someone told me recently that getting a static IP address can be expensive. Is this true? Currently all networks have DHCP enabled, and the routers are set up to use DHCP. My thoughts were to disable DHCP and assign ip addresses manually.

I have been using my DIR-655 for about 2 weeks now with Road Runner wideband services. Starting yesterday my internet became very slow and I discovered the cause was the router. I tried resetting it to factory settings and things will be fine and run smoothly for about 5-15 minutes but after that it goes back to being extremely slow. My speed tests would go from 10ms (normal) to 250-450ms. Before this issue occurred the Dlink was perfect, had full speeds. I am running a wire Ethernet connection.
I am currently using revB and tried upgrading firmware to 2.01NA which had no effect, but make my internet seemingly go back to normal for the first few minutes then nosedive again.I have also changed my speed/duplex settings in Network Config to 1gbs Full Duplex. I've also disabled QoS, and still no change. Not sure what else to do.
When directly connected to the modem everything seems fine. The modem is also the provided Motorola SBG6580 which I have called Time Warner to set the modem into bridge mode and have the DIR-655 connected to it.

I manage a CISCO 4404 WLC with about 46 access points across our WAN. System works very well, serving trusted users, guests etc very well.However, over the last month or two we have had an issue where we have had high load on our WAN.We have traced this down to the CISCO 4404, about 3-4 times a day, the controller connects to every access point and transmits about 5-8mb of data on port 5427. This in itself would not be a problem, but it connects to all 46 at the same time.
