Computer Causing Router To Lose Internet Connection?
Dec 9, 2012
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.

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'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.

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.

This only started about a week ago and everything was working fine before then. My router is causing my internet to be slow (I know this because it goes at normal speed when I am connected directly to my modem)

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.

I have a disconnecting problem with my WRT120N (Linksys) wireless router. Sometimes all wireless devices lose the connection to the internet, and the access to the router administration page (192.168.1.1) becomes impossible. In this case LEDs of power, internet and wireless are lighting without flashing. This problem usually occurs every 48 hour, and there was no way to make a reconnection except turning the router off by unplugging the power wire and plug it again…
I hope find a solution for this problem here
Other question: are there any problems in Firmware Version: v1.0.04
Note: currently I use Firmware Version: v1.0.01

I have taken on a new client who has the following setup, BT Infinity, Vigorpro 5510, and SBS 2011 server. I was involved with unpacking and seting up the equipment to get client up and running. I have never setup a firewall before, and after contacting Draytek, they guided to get BT infinity, 5510 to talk so that the server was able to get onto the internet. The setup was then left in its default state.All was fine until lately, the client keeps losing internet approx same time most days.My problem is how do i get the 5510 properly configured to talk to BT infinity, and sbs 2011. I always get lost when it come to playing with IP address. Also the client has a fixed IP address supplier by BT, so want to know how to setup the vigorpro with this address. [code]

I have a Cisco WRT120N Router and a Cisco Valet AM10 wireless adapter. Almost every time the computer reboots, I loose my network and I have to redo the AM10 setup. The AM10 is the only device that loses the connection, my lap top and printer do not lose the connection.
Problem 2: Everytime I upplug and replug the AM10 a window pops up saying I need to check the drive for errors but none
are found.
Problem 3: I downloaded the AM10 install program, Downloadable.Setup.AM10.1.2.10148.2. It does not work. If I try to run it Iget an error message that the setup canot be completed and to call in for support.
Problem 4: When I can get it working is shows that it is Wireless Connection 5. Why 5 and not 1? Where are the other 4?

I CONSTANTLY lose connection to the net .Then it takes forever to rejoin the net.I know this PC has ASUS Wireless Console 3 installed on it. I have, in the past, tried a few fixes offered on websites for suggestions when you lose wireless connection (i.e. Setting a static IP to connect to, turning on firewalls, etc.) none have worked.

If I do a factory reset on a router, does that mean the computers on the LAN will not be able to access the Internet?but then the router will configure it's self automatically to re-allow connection ?

Every time I boot up my computer, everything will be working fine for about 5 -10 minutes, but after this, all my browsers will lose connection to the Internet. All of them: IE, firefox, chrome, even the steam browser, all of them just lose connection.The weird thing is, my net connection is perfectly fine: I can still play online games, still use online chat services, still open and use programs like utorrent. It's like something is just blocking all my browser connections.When I run a network troubleshooter, it says "your computer appears to be correctly configured, but the device or resource (Microsoft Corporation: Software, Smartphones, Online, Games, Cloud Computing, IT Business Technology, Downloads) is not responding."I googled this and came across some apparent fixes like flushing and re-registering my dns and restarting my modem, niether of which has worked.In addition, this problem is showing up on two totally separate shared networks and has only affected my computer. Other netwworked devices, like friends/families computers and my iPhone (which I am using to type this) work fine.

I do love your products and I am not just sucking your *beep*, but could you please update the firmware on this modem (DPC 3008). There are a lot of people that are having issues with losing their internet connection when it comes to this modem. It doesn't matter who the ISP is, doesn't matter what we try to do to fix this. I read somewhere that after you updated the firmware in 2011 on this modem is when your customers starting having issues. Now I just bought this modem a few weeks ago so I don't know for sure. All I can say is if this issue doesn't get resolved, I am going to smash the *beep* out of it and never recommend your products to anyone as well as never purchase another product from you. I like you I really do, but I am tried of losing my internet connection when I am playing my games or watching movies. People have stated that they removed your modem for a different brand and their issues were resolved. I am giving you a chance to show me that you value your customers and you will resolve this issue in a timely manner

There is going to be 2 computer and a router each with there own static public ip address (ie 68.x.x.x range) The issue i am running in to is getting the netgear set up correctly, every time i disable the dhcp server on the netgear and set up all 3 devices with the static ips i lose internet connection. If i leave the set work set up as dhcp on the lan side and keep the wan static ip it all works fine.

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 have been using a Linksys E3000 router for a few months now. Love it. But this last week, when ever I wake my monitor up after it's power saving mode kicks in, I lose my internet connection for about 15 seconds. If you look at the router before the monitor is on, I am connected. The light is on for port 1. But as soon as my monitor gets turned back on, it light just turns off and will reconnect after about 15 seconds. I've looked it up online and can only find things about when the entire system wakes up, and usually those people have to reboot their entire system to get a connection again, or turn the router off then back on. Using Windows 7?

So i have AT&T dsl internet. but whenever i connect my computer wirelessly to the modem and get on the internet it repeatedly loses dsl connection every some odd minutes. the dsl light on my modem turns off, then blinks red, then fixes itself for five or so minutes until the cycle restarts. ive tried 2 wireless usb adapter and 1 internal wireless card. none have worked at all. but if its wired with an ethernet cord it works fine. we also have 2 other laptops that connect wirelessly and work fine. i dont understand what would cause this solely on my computer. ive also had AT&T come to my house and look at it and they said its fine, the issue is somewhere in my computer messing with the modem.

I have had numerous issues with my E3000 since I got about two months ago and they have all been resolved with the exception of this new one that popped up today.
My Samsung Blu-ray player is connected firectly via ethernet cable to the router. When it's on, I lose all conenctivity to the router with my wireless devices including three PC's, a PS3, two iPhones, one iPad, one Samsung Smart TV, one XBOX 360 and an Onkyo Receiver. When I say that I lose connectivity, I don't mean that I lose access to the Internet. My PC's see the network but cannot connect to it, the same goes for the Apple devices. The moment I shut off the Samsung BD player it kicks right back on and works normally. Until today, this never occurred.
I contacted Tech Support and they had never heard of this happening before. They suggested that I change the ethernet cable which I did while the unit was on and it worked until I turned the BD player off and turned it back on again. I also tried switching ports to no avail. Alos all of the software is up to date on both the router and the BD player.

I have a very well updated Laptop running XP well patched with IE7.I have run all the malware scans and there is nothing wrong on the PC.After exactly 10 minutes of the PC being on, wireless internet connection is lost, BUT:Signal Strength states "Excellent" I can't access any website at all on the web. (Except for "Facebook" for some odd reason?) I can't access it after the 10 minute mark but if I'm already on it, I can navigate thru it's site without being disconnected, don't ask me why I have tried the following:
- Dynamic and Static IP setting
- Turned on and off windows firewall and rebooted each time
- Ran all kinds of malware detection and virus scans
- Disabled power management on network card
- I've tried different PCs on the same network and they're fine
- Tried ipconfig release and renew
- Tried repair connection
- Tried netsh reset
- Tried FireFox and other browers
- Logging off and back in doesn't work, must restart the computer to get another 10 minutes

We are a small business with about 9 Macbook pros and 3 PC's connected wirelessly to the router. The Mac-computers sometimes lose their wifi-connection to the router. When this happens they have to select the wifi network again from the menu, to reestablish their internet connection. For some of the clients, this happens about once each day and for others multiple times a day. The problem doesn't seem to appear on the PC's.
I have tried to solve the problem by making DHCP reservations for each computers MAC-address, but with no luck. I also tried to set the 802.11 Mode to 'Mixed 802.11n and 802.11g', and turning WISH off. I read that the connection can be disturbed, if other wifi-networks in the area uses the same channel, so I changed it to channel 3, based on a scan of the network, where 3 appeared to be the least used. The WPA Mode is set to 'WPA-2 Only' and Cipher type is 'TKIP and AES'
The Dir-655 is hardware version B1 and the firmware is 2.0.

We are having several workstations that are momentarily losing connection to our Windows Server 2008 machine that hosts their Documents etc.It seems like a momentary disconnection and not everyone has complained although I'm guessing that unless you are trying to locate a file etc at that moment you might not notice.Here is the error message I see in the event logs on the server:
-Source: srv
-EventID: 2012
-Level: Warning
While transmitting or receiving data, the server encountered a network error. Occassional errors are expected, but large amounts of these indicate a possible error in your network configuration. The error status code is contained within the returned data (formatted as Words) and may point you towards the problem.So, where would you guys start with something like this? Either my HP Procurve 1800-24G doesn't have much in the way of error logs, or I don't know where to look.Would you start with changing port on the switch, changing network cable or do you think it's more likely to be something on the server itself?

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 have a DIR-825 router series b, with firmware 2.05NA.My desktop is running vista 64Bit.I want to use my xbox 360 as a media center.I lose my connection between my xbox and my computer whenever the xbox is turned off. I can connect, and it works well, but only after I uninstall the extender from Media Center, then restart my computer. Then it sees the xbox on the network. I then have to set up a new connection. This is done over wireless N using the 5ghz band.The connection holds until my xbox is turned off. Then when I turn it back on it does not see the connection to the Media Center.
I updated the new firmware (my previous firmware was 2.02NA). I updated to 2.06, but then went back to see if that would make a difference and it didn't. The xbox can connect to xbox live and the internet (netflix etc...) but it does not see the home network to allow me to stream media between the computer and the xbox.I have disabled the firewall on my PC, I have disabled SPI, and do not have any other firewalls running on the network.

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 got a new router, a Cisco Linksys EA3500, and everything works fine and no one else in my family notices anything. Everything works and I don't have trouble accessing the internet and I always get 5 bars, but whenever I play a game online it will disconnect me after a while. Sometimes it disconnects me after 5 minutes and sometimes after 30 minutes. The only games I play are Arma 2 and Garry's mod and I have the same problem with both games. The weird thing is that I talk to friends on steam when we are playing and it doesn't get disconnected I can hear them fine, and my internet access bar at the lower right doesn't say I'm disconnected. Streaming and downloading work as well. I have no idea what to do, we got a new router because the old one was faulty and we called our isp and they said there was nothing wrong on their end it.
