At our house we have Fast Access DSL through ATT. We are getting very frequent disconnects and lags. We have multiple devices running off of a single DSL modem/router. It has wireless and wired connections available. Our wireless devices disconnect as frequent as our wired devices do. We have called ATT many times. They have had us replace the DSL filters and did a line test outside our house which came back clear. However, when they run a line test while I am on the phone with them, they say they detect multiple errors on the line. We have replaced our DSL modem with a new one as well. It is a NETGEAR VersaLink Four Port Ethernet Wireless Gateway, Software VER:06.04.12. The self-diagnostics on the Modem come back clean with no problems detected. We get static on our phone line frequently as well.

In the technician readout part of my modem I also see this:
1Manufacturer NETGEAR
2Vendor ID b5004946544e449c
3Model NumberB90-755025-15
The internet connects fine, but every couple of minutes it will disconnect for a couple of seconds. It's not a big deal when browsing, but it's disastrous when downloading big files or playing online games.What I've tried so far:
-Resetting the modem. No change. -Reconnecting the modem/router completely. No change. -Replacing the main splitter. Slight change, but problem came back eventually. --Original problem came with the tech's 2 way 5-1002 mhz spliiter. --I tried replacing it with a 3 way 5-1000 one. The modem on 7db and cable on 7db. It worked fine for a couple of days. --Problem comes back today. Moving the modem to any of the 3 outputs doesn't fix anything. Moving it to 3.5db actually causes a short timeout every minute when I try to ping yahoo (as a test). --I've also tried a 2 way 5-900 mhz splitter. It was the worse one of all.
Other info:The internet went down to the entire block at the start of the year. No one knew this of back then so we made a call to comcast, and they scheduled for a tech. A couple days later, we decide to get a new modem from the comcast center just to make sure it wasn't our modem. Some problems with activation prevents us from knowing if it was. We get back online somehow the next day, which is also the same time the tech came. He decides our numbers are weird and adds in a splitter for the internet and tv (which leads into another splitter for each room), and an amplifier for the tv. In the middle of this, another tech stops by and tells us the entire block was down and he said he fixed it now, he doesn't stay long. The first tech finishes installing everything and leaves. All is fine for a couple of days, until a week later and we start experiencing frequent disconnects. We've tried calling comcast again, but they say the connection is fine on their end and the problem is with our router. When I ping the router and the modem directly, there are no dropped connections. It's only when I try to ping anything on the internet when the problem pops up.
I've recently bought an Actiontec V1000H gateway from Telus because my previous gateway burnt out. It seemed to work fine at first, but then I started getting disconnected at random. The only way I have found to fix this issue temporarily is to ipconfig /release and /renew.
The modem checked out and was all good, the splitters are brand new and the line is apparently fine.This left the router as the issue. We had a Netgear router and attempted to replace it with a Linksys router.The firmware on both routers have been tested both old and new firmware.This happens to all computers/laptops connect to the network I do not receive a message stating that I was disconnected from the network, the internet simple cuts out for a little while and then comes back in.Cox says that they are 100% certain it is not on their end, nor is it the modem.The disconnects occur at random (there is no specific intervals). They last anywhere from 30 seconds to 10 minutes.
I am using a desktop with a Netgear WG111v2 dongle to connect to my cisco linksys router.Basically my old modem died which was connected to a wireless router so we replaced it with a cisco linksys router and ever since the change ive been having difficulties connecting to internet on my desktop where as the the rest of the laptops in the house have had no problem. In the begining the desktop would always say its had limited connection the the network and such i couldnt connect to the internet but disconnecting the router several times and restarting the computer several times eventually the computer would have full internet access through the network without disconnecting at all.
A few days later the computer starting connecting to the network and gaining full internet access usually without turning of the computer and restarting it although i would disconnect from the internet every now and again for a minute or so and reconnect automatically this would happen more frequently when using Skype or msn messenger extremely frequent when using skype and especially when in a call.ive updated the driver of the wireless dongle to the latest version.my desktop is running vista while the laptops are running windows 7 and mac osx or whatever.ive also download a free version of avast and given a full scan of my computer without finding any threats.
We recently converted autonomous 1131APs to LWAP. We have some 802.11b clients that were associated to these APs and they worked fine. Ever since we converted them to LWAP, the clients frequently disassociate and it causes alarms on these wireless clients which are used as monitors.
WCS shows the client disassociation and re-association and it says the roam reason as "unspecified". It associates to the same AP and keeps the same DHCP client address etc. I tried setting a static IP on the client but that did not work. We verified the PSK settings and they all match between the clients and the controller. [code]
I have a new deployment with a Cisco 5508-50 controller running 7.0.220.0 code and 35 AIR-LAP1262N-A-K9 access points. Current legacy clients have trouble connecting and after connecting they may or may not drop off and have trouble connecting again.
I have a Cisco/Linksys E2500 router that I have had for over a year and it has worked without issues for over a year. However my wireless ISP just switched my CPE from A Mikrotik wireless radio to a Ubiquiti wireless radio. As soon as they did this my PPPOE sessions from the E2500 (acting as my PPPOE client) start disconnecting and reconnecting every few minutes causing major problems with my internet and voip connectivity when it looses connectivity every few minutes.
The strange things is if I connect my much older WRT54G router as a PPPOE client (with the same exact PPPOE configuration), it works just fine and I don't have any PPPOE disconnects.
I upgraded to the latest firmware on my E2500 and nothing changed, it still disconnects my PPPOE sessions probably close to 50 or 100 times an hour.
I'm thinking it's some sort of compatibility issue between the Ubiquiti Nanobridge Radio CPE and the E2500 router acting as my PPPOE client. Also another thought was that perhaps my ethernet port wasn't negotiating speed/duplex correctly on the E2500.
Is there any way to hard code the speed/duplex on an E2500? I can't seem to find any spot with that setting.
I am having a similar problem to a couple others with the dir-651.Frequent Disconnects difficulty even connecting to routers home page.Internet worked ok on dir-615 i had before, just slow gaming speeds occasionally running vista 64 Timewarner cable.And i do have the newest firmware.
Older model Inspiron 1545' using the 1397 WLAN card. Has been working fine, until perhaps the past two weeks. Now it frequently drops out, requiring manual disconnect and reconnect. Tonight Internet very slow on that laptop.
There are other devices using the same wifi (including this iPad used to post this), which connect to the wifi and Internet no issue. To me, its pointing to the laptop - either the WLAN card itself, or something in the laptop starting to fail (the laptop does have issues restarting - where it won't do that unless left for say 30 mins).
I'm suspecting a recent windows update or mcafee security update - no other software has been installed or updated.
I've tried changing antenna setting from auto to aux with no change to the above. Have checked for newer drivers - the laptop reports the version we have is the latest ( from 2009) - although they are the windows driver. Running windows 7, 64 bit - as supplied by dell when laptop was brand new. should I give up on the 1397 card and use another USB wifi adapter ?
We just upgraded our internet, which also meant installing a new WiFi router, and mostly it's working fine. The two desktops and two of the laptops in the house all play nicely with the new router, but the third one (an old Fujitsu Siemens AMILO La1703 running Vista Basic) mostly stops responding when I try to connect to the new network. Any other network works fine. I can't actually connect to them since I don't know the keys, but it doesn't affect the laptop. When I try to connect to our new network however, the network connection dialog boxes stops responding and if I try to restart Explorer I still can't open any network related settings or menus. Most of the other stuff works.
I have tried manually configuring the network with the SSID and network key, but the result was just that I couldn't open the network settings at all, even after a reboot, since it was already trying to connect. I have also tried booting up in network enabled safe mode, same thing happens. All drivers are the latest. If I connect it to the router with a cable everything works fine.
my laptop is lagging on all fronts when connected to the interweb and i have no idea why, i dont know what specs you would need in order to diagnose but heres the spec page
We have one router and we plugged a second computer in. We first played Battlefield 3 and both had fine pings. Later, the original computer, which had always used this router was fine, BUT. The other computer began (I guess) to have problems. Diablo 3 and League of Legends had almost unplayable pings (well, around 200). In the meanwhile the other computer was playing BF3 with good pings.
I bought the Dlink 655 about a week ago, it worked fine online via Wi-Fi for my Ps3 for the first few days, then after the first few days it started lagging. It will have little lag jumps every 5-10 seconds and it is really annoying and it really makes playing online impossible. Also it wont let me view videos through the internet on my Ps3, I never had this problem until I got this router
I have the Dlink DIR-655, Rev-A, HW 1.35NA Wireless Router Before you ask, I have reset the router to factory defaults, and reinstalled the latest firmware twice, most recently after trying everything else I could think of.I have Cable internet, ALWAYS using wireless, NEVER using wired except for the router installs, which worked just fine until I switched from my old D-Link router to this 655 one a few weeks ago.Now, very frequently, I will open ANY webpage, and the internet will lag, 5, sometimes 10 or 15 seconds and then suddenly it will work properly for a while... only to happen again a little while later - completely randomly it seems.I wired the router to the computer to check to see if the lagging still happened, and everything was fine.I am using a 1-year old Dell laptop, using Windows 7 Home Premium, 64 Bit, and the Network Adapter is Intel WIFI Link 5300 AGN with the most up to date driver confirmed. Under the Advanced Tab for the Laptop's Network Adapter, the settings are as follows:
802.11n CHannel Width for band 2.4 - Value: 20MHz Only 802.11n CHannel Width for band 2.4 - Value: Auto 802.11n Mode - Value: Enabled
There are a number of other settings which I am confident are not relevant, but happy to provide The last setting is: Wireless Mode - Value: 6. 802.11a/b/g In the DLink Configuration, the relevant settings are:
802.11 Mode: Mixed 802.11N and 802.11G Wireless Channel is on 10, so as not to use the most common "11" Channel Width Auto 20/40MHz DNS Relay Enabled DHCP Server Enabled Range: 192.168.0.100 to 192.168.0.199
[code].....
Under WAN, the Primary DNS Server numbers are showing and the Secondary DNS Server numbers are showing as 0.0.0.0 McAffee Anti-Virus is up to date and shows no viruses, nor to the Dlink Logs - McAffee Firewall is turned off, Enable SPI in Dlink Settings is turned on.this problem only occurred when I switched routers recently, the old DlInk router I had never had this issue. And I am using a completely different network name with this new router to avoid any conflicts there. And this problem does NOT occur when hardwiring the laptop to the router directly, it only happens via wireless.Storage of the router is fine, it is in the same spot as the old router was, not to hot, not too cold, it didn't eat any metal for breakfast and there are no MRI machines within 10 miles.
Does the 22xx Series FEX support static or dynamic LAGs between itself and a server?Imagine a server with dual 10G NICs, and I need to connect them to the SAME 22xx FEX....can I set up a LAG between the two 10G NIC ports and two 22xx FEX Host ports? Does it depend on how the FEX is connected to the parent 55xx?
I'm having alot of trouble trying to connect more that one LAG between two SG300-52 switches.Basically i have configured both switches with the same vlans. For 2 of the vlans i would like to connect them together between the two switches using LAG. Switch1 has Vlan 5 (ports 1-12) & Vlan 10 (Ports 25-36) with LAG configured on ports 1-2 and ports 25-26. I have setup the second switch identical to the first. But when i connect the LAG's there is no connectivty. If i disconnect one LAG the other starts working.Can you only have i interconnect LAG between switches?
I have a problem running Airplay through the wireless on my W881. It runs okay if the computer i run it from, does nothing else, but if i try to do light browsing or anything like that it starts to fall out and lag. Its like it is not prioritizing the stream at all.
My setup is a w881 running as edge router and i got an Airport express running through a 2950 switch. Airplay runs perfect if i run it through the Airport express or my previous Edge router (Linksys WRT54g). Ofcourse it also runs perfect through the wired network. I shut down all other wireless networks but my w881, because i only want one wireless. And no i dont want to run wireless on the Airport express.
i played around with the Dot11Radio0 interface setting "packet retries 128 drop-packet" and the packet "max-retries". I thought that maybe if i set max-retries to something low, it wouldnt fall out if it has some problems with one packet, it would just continue...
I just got Charter cable internet and decided to purchase my own cable modem instead of paying 5 dollars a month to rent one. I got a D-Link DCM-201. I know it is a little old but it was brand new/unused so I figured it would work out well. Ever since we got it hooked up every few hours we lose internet connectivity. The power, cable, and status lights are solid green and the Ethernet light is blinking green. The only fix I have found for this is to power cycle the modem. The problem is this happens about once every 4 hours...having to reset the router every few hours is making having cable internet a much more painful experience than it should be.
I keep losing connections to the internet and getting a couple of different messages that the Gateway IP address is invalid. There are times it happens every few minutes and other times I can go for a couple of days without it. Also, we have to have satellite internet which has such an inconsistent speed. Is it the internet speed inconsistency or the 4 year old Belkin N Router?OK, so I tried to copy the information from the CMD window, but I can't get it to work. After I got the information and right clicked and clicked "select all" then what. I couldn't copy it. I can't find my way back to the instructions.
I am having issues with frequent bgp flaps on the Cisco 7200 series router from past 1 week. I have raised a ticket with ISP but couldn't get any resolution from them as the flap is for about 2min.When ever we see BGP flap, we are not able to ping the remote end IP, Also at that point we drops on the interface connected to ISP.
I have a Cisco 1841 router which stops functioning sporadically. You have to manually go do hard reboot on the router before it starts working properly.When it goes down, you cannot ping its internal interface (from the LAN side) not its public interface, it seems to go down quite regularly.Where do i start to diagnose, is it hardware failure, or config issue. Nothing has changed as far a the config goes lately.
I have Cisco 7613 on my edge(MPLS Backbone). CPU utilization is shooting to 100% at frequent intervals. When I tell vendors managing device they tell that it is happening due to one of my server(connected on Fast ethernet port of 100Mbps) generating heavy traffic. My questions are:
1. Can a router of 720Gbps capability be choked due to traffic generated by 100Mbps link?
2. Interrupt CPU process utilization is well below 10% at the said time. BGP router process consumes most of the CPU. Does this means that server in question is generating too many routing updates?
3. Is there any way that I can limit routing updates on a particular link?
4. how to check which link is causing more CPU utilization.
I am running XP pro. I have checked thoroughly for viruses/malware/etc. and everything appears to be clean. I have up to date drivers for NIC's, have cleared all temp data, done basically everything that the first tier Time Warner Cable(my ISP) tech support people will tell you to do as they read from that frustrating script we're all too familiar with and have had to deal with time and time before, including resetting modem and router, bypassing router, etc. etc. et bloody cetera.Ran several pings to a variety of servers and noticed ping spikes every 10or so seconds into the 300-600 range from an average of about 20-30ms.
I have moved into an apartment with 4 friends of mine. We all own HP 6515b Laptop running Windows 7. We connect to the internet through a wireless router. Our connection's name is LINKSYS and is WEP.Once i have connected to the internet, it will continue to work fine for a while. After some random time, it will disconnect.(The computer stays connected to the wireless modem, but computer shows NO INTERNET CONNECTIVITY (in bottom-right taskbar))Then in 5-6 seconds, it will start working again... The only change that is visible is that the exclamation mark on network disappears. The computer remains connected to router for this whole time. Initially we thought it was a problem of our ISP. But later we found out that at a time not all users face disconnection.So at a particular time, it is possible that only I cannot open webpages.
I am running Windows 7, Time Warner Cable is my ISP, I am using a Netgear wireless router, and a netgear wireless card to access the signal
The problem started a week ago. While playing online video games (Battlefield 2), I will get a message on my screen telling me theres a problem with my connection. Sometimes it will only freeze up for 5-7 seconds, and sometimes it is up long enough to make me lose connection to the server.I am not having ping problems, the server is not kicking me for that.All background programs are closed, ive tried restarting everything I have thats related to internet and my computer.
I have multiple RVS4000 in a VPN ipsec Site to site to a ASA5505. The connection is fine most of the time.But the VPN connection randomly drops, not all the devices at once but they all do at a different time.
I am trying to configure MSTP on Layer-2 network at work. We have multiple switches connected on Wireless point-to-point links with redundent links.MSTP is configured with multiple regions. All the servers are located in RegionA and other regions are connected to RegionA via multiple links.
There are 3 SG-300-10 switches in RegionA --- SwitchA_1, SwitchA_2 and SwitchA_3.One of the simple regions (RegionB) has a single SF-300-08 switch (SwitchB) connected to SwitchA_2 via port e7 and SwitchA_3 via port e8. Hello Time, Forward Delay and Max Age are at their default values of 2, 15 and 20 respectively. The link between SwitchB (port e7) ---- SwitchA_2 is the primary link with cost 200,000 and the link between SwitchB (port e8) ---- SwitchA_3 is the backup link with cost 500,000.
The log on SwitchB is shows in the table below. As it is seen from the table there are frequent topology changes for very short duration (1-4 seconds) before the topology settles back to the configured one. (Primary link forwarding and secondary link blocking). During this time there have been no link failures reported.Same thing is also observed within RegionA (SwitchA_1, SwitchA_2 and SwitchA_3 are connected to each other).
How to stop these frequent topology changes? The topology changes within RegionA causes a lot of PPPoE sessions to reset and re-establish.Is there any way to find out what triggers these topology changes?

I have been experiencing drops in my wired internet connection and a google search brought me to your forums.It seems to disconnect more often either during a call on my voip phone (a snom) or shortly after - as if a surge of usage makes it drop out?
I have a DIR-655 and OVERALL like it -- but there is one HUGE flaw.
I have set up several MAC address-based rules/schedules to restrict the times of use by my kids. FOR THE MOST PART these work fine (all clients on wireless). BUT at random intervals, all of the PCs with these MAC-based rules/schedules in place suddenly lose their internet connection (i.e. get blocked by the router). This does not happen to me or my wife (neither of our laptops have MAC-based restrictions in place for them). A reboot of the router reestablishes connectivity for the blocked machines. This reboot is something I find myself doing daily -- sometimes multiple times per day. I have verified that the latest firmware version is in place.
As indicated in the subject, wireless users are finding that it is either unattachable (shows up in the list but fails to attach) or if you manage to authenticate and get in, it's painfully slow or simply drops out. Security is WPA-PSK. Only noticed the issue after a couple of Windows 8 laptops came into the household, but the problem still seems to be there when they are off so not sure if they are connected in some way or not. Updated to the latest firmware - no change. Wired connections are fine and when it's initially restarted, so is the wireless, seems to happen sometime after wireless services are restarted. Only the one Wireless SSID, nothing fancy, max users around 5, all on laptops or the odd pad. I changed channels done narrow wide etc, (using mixed mode - some Wireless N laptops some Wireless B/G. Nothing seems to make any difference. No log entries until the Wireless system is restarted, doesn't require a reboot of the router, just a SUBMIT of the existing wireless settings to force it to restart.
- Small Home-Office network based on a Cisco WRV210 VPN Router connected to another WRV210 in a remote location. - The WRV210 provides 2 WAP-protected SSIDs, one for the office network and one for visitors - Wireless channel is set 5 channels away of the closest networks (using inSSIDer) - There are about 12 wireless devices, 4 connected to the office network the rest to visitors. Not all devices are connected at the time of failure. All wireless devices use DHCP which is set to last 1 day and provide 100 IPs. - The wireless devices are 1 desktop, 3 notebooks (all clean), iPads, iTouch and Nook. - The failure symptom is that almost daily, and most likely around the same time, no wireless device can connect to any of the SSIDs unless the router is power-cycled. During the failures, which we have witnessed first hand, there are no apparent reasons: no new SSIDs, now SSID in close range on the same channels, nothing we can easily observed in the network in terms of connections or unusual activity. - A weirdo also presented by the WRV210 was that its web pages were shown erratically. That was corrected by downgrading the firmware from the latest to previous version.
We have used a loaner Linksys router WRT54GC with only the visitor Network on it and even though the situation is not as frequent, it has happened already a couple of times.The WRV210 is out of warranty and discontinued, so we get no support from Cisco that is worth paying for.
I have problem with RV120W router, device reboots very often ( up to 3-4 times during working day ), firmware is up to date ( 1.0.4.10 ), last week I decided to use "restore the factory defaults" unfortunately problem still exists.
Router is working in small office, there are 3 PC and 3 VOIP phones ( connected via LAN ) and 1-2 devices connected via wireless ( smartphones )
I've tried to view some logs but unfortunately no luck, can see some errors/warnings in dashboard ( see attached picture ) but cannot see more details ( log configuration wrong ? )
Additionally sometime I can see that CPU utilization is 100%
