Linksys Wireless Router :: WRT54GH Frequent Disconnection With DSL Modem

Jul 9, 2011

I purchased WRT54GH wireless router back in 2009 and it was working fine except for past 1 month, wherein the Internet Connection was being disrupted 15 - 20 times in an hour. I thought it could be fault from ISP end; however after investigation by ISP we found the fault was not from ISP as, when Wireless was unable to establish connection with the DSL Modem it was failing but when tried to connect laptop with the DSL Modem it worked fine (Wired connection). I did try the Settings mentioned in an earlier post to change the UPnP and the Beacon Interval etc. This however doesnot seem to work as the internet has been disconnected almost thrice since then. (Approx. 15 - 20 mins). When the router is unable to connect to internet I restart the Wireless Router and the DSL Modem. After restarting, the Internet connectivity works fine.
 
Below are the Advanced Wireless Settings from Wireless Tab:
 
Authentication Type: Auto Shared (Default: Auto)
Basic Rate: Default (Default: Default)
Transmission Rate Auto (Default: Auto)
CTS Protection Mode: Disabled Auto (Default: Auto)
--------------------------------------------------------------------------------
Beacon Interval: (Default: 100 Msec, Range: 20 ~ 1000)
DTIM Interval: (Default: 1, Range: 1 ~ 255)
Fragmentation Threshold: (Default: 2346, Range: 256 ~ 2346)
RTS Threshold: (Default: 2347, Range: 0 ~ 2347)

Frequent Disconnection Of Internet - Cannot Open Webpages

Mar 16, 2011

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 recently purchase WAG120N on a recommendation from a cisco personal, after my long year work horse Linksys AG 241 went kaput.Since I have purchased it WAG120N it is never stabilized on the MTNL ADSL network. There is too much of frequent disconnection. Although I have raised this issue with cisco support # 121128-000336 and 121122-004290, but all they have asked me to replace the WAG120N gateway. [code]

Linksys Wireless Router :: E1200 Frequent Loss Of Connection

Feb 3, 2013

Having several issues w my E1200. For quite some time I have had intermittent loss of internet connection. This was somewhat true even before I got a wifi router. & it has continued. Recently it has been even worse & I'm not sure if it is my isp, my cable modem or the router. ISP came out & checked & said signals looked ok, although modem is old.Now i find out that the version of Cisco Connect that i had been using is incompatible w Mountain Lion so it won't work now. & newly downloaded dmg files say they are damaged (or that app has been modified or damaged--I'm not in a position to tell which but same results after I downloaded a 2nd time).
 
I have been having more frequent loss of internet connection at home. & when I click on the wifi icon to check, it shows it looking for networks. Also it has not been uncommon to see that it has switched to my guest network.Why would it switch to my guest network? What is the difference between the 2 besides the fact that I guess the guest network doesn't have access to everything on my regular network (which right now is only my iPhone, but may get wireless printer).Also when it shows the lists of networks that it "sees" my guest network does not show a padlock icon so what does that mean? It does have the default password.
 
Also because I had no idea that Cisco Connect was not compatible w Mountain Lion I didn't even think to check for upgrades before I upgraded to Mountain Lion & now I can't open Cisco Connect. Shows unsupoprted OS. & I'm also stalled trying to update the firmware for the router.I'm really beginning to see why it was cheaper than an Apple Airport Express. Even at a very low hourly rate, the lost time spent when this has not been working right has not been worth what I saved on the purchase price.

Frequent Loss Of Network Connection?

Nov 22, 2011

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.

Frequent Ping Spike Comes And Connection Non Responsive

Sep 19, 2011

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.

Frequent Connection Drops Running Windows 7?

Apr 23, 2011

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.

Two Computers Cause Wireless Disconnection?

Apr 14, 2012

I just recently had comcast high-speed cable installed, and purchased a Linksys E2500 advanced dual-band N router to get myself going. I'm running an Asus G74s series laptop with windows 7 and everything runs great while I am the only one connected.That being said when another laptop connects (Toshiba satellite also windows 7) the internet stays stable. It isn't until we try and do something that the internet randomly disconnects for 2 or more seconds before re-connecting and putting us in a constant loop of idiotic disconnection.

A quick example would be using the Toshiba to connect to World of Warcraft, I on my Asus can surf the web just fine for about an hour before it disconnects. When I try connecting to a, or the game at the same time it'll allow play for about 7 mins before the net drops for a few seconds then re-connects. This happens frequently no matter the time of day.I have attempted re-setting everything. Everything is up to date including the router. I've attempted to release and renew my IP. However I get this :

Persistent Wireless Disconnection From New Computer Only At Home?

Oct 19, 2011

I've just got a BRAND NEW HP dv7-6197ca

Specs: Windows 7 64 bit
Processor: Intel i7-2360QM 2.0 Ghz with Turbo boost technology
RAM: 8GB DDR3
Graphics: Radeon HD 6770m 1GB
Storage: 2 x 500 GB 7200rpm
Network Interface: Integrated 10/100/1000 Gigabit Ethernet LAN
Wireless: Wireless LAN 802.11 b/g/n. Bluetooth wireless networking with WiDi

So problem is with persistent disconnection from my landlord's wireless hotspot. The usual exclamation mark at the wireless bar indicating that I'm connected to the network but I don't get internet access...I've got the computer checked up by STAPLES where I bought it and everything was in perfect shape, network card fully functional... I mean it is brand new. They even reformatted the computer and installed clean Windows 7 with no crap software in it...I brought the computer to school and internet works FLAWLESSLY. Disgustingly fast.The problem is only when I'm at home where my internet would work fine for say 5 mins and then the exclamation mark will pop at the wireless bar and I would lose internet access for half an hour or more. I would get the access back and then it would disconnect again.

I called my ISP and they suggested to change my wireless channel to a unique # say channel 11 from 1-11. Turns out the wireless channel already is on 11... I then got it changed to 1 by my landlord. Still same situation. We then tried to change the wireless security encryption (e.g WPA-personal to WPA2). My computer can't connect in that case...On a side note I do have an older laptop (~7 years old), the one I had before purchasing this new computer. This old laptop can connect to the wireless and work PERFECTLY.

So the problem happens only with this new computer, and only at home. I'm completely clueless as to what the problem might be. It looks like some kind of interference but I've tried changing wireless channel (from 11 to 1) which didn't get rid of the persistent disconnection. Could it be interference with another computer that's using the same wireless hotspot in the house?

Cisco Wireless :: SF302-08P Switch / 8 WAP200 - Massive Disconnection?

Feb 19, 2012

For a customer of mine I've installed 8 WAP 200 access points with an SF302 switch. The Access point are powered with POE. All seems to function properly: the clients are simple Android device and the connection appears solid.. We've a good roaming between access points (not seamless of course but is ok) and no particalur problems, also because the network is used to drive very LOW data (no internet): the clients opens a tcp connection to the server and sends only a keep alive packets over this connection.. Then sometime the server send a very small amount of data (some byte) to activate the display of the device and show a question.. the clients reply with some other byte of data and so on.. During an event of 3/4 hour we can do this 12/14 times, so the network load is nearly 0....

Last night the system suddenly stopped working: ALL clients (300) lost connection from their access points at the same time! How this can happens? The only reason that I can imagine is a power loss on the switch...

Cisco Wireless :: SRP527W LAN Requires Frequent Restarts?

Jun 7, 2013

Have an SRP527W that I've had a couple of years,
 
Model:SRP527W, ADSL2+ AnnexA, 802.11n ETSI, 2FXS/1FXOVersion ID:V03Hardware Version:4.0.0Boot Version:1.1.17 (Jan 4 2010 - 21:15:46)Firmware Version:1.01.29 (002) Mar 29 2013ADSL Firmware Version:0.78.0Recovery Firmware:1.01.20 (011)Setup Wizard Version:20110728.00 

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.

Cisco Wireless :: 1131AP Frequent Disconnects For 802.11b Clients

Apr 18, 2011

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]

Cisco Routers :: WRV210 Wireless Frequent Disconnections

Feb 18, 2013

- 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.

Linksys Wireless Router :: WRT120N - Disconnection While Playing Games

Jul 18, 2012

Just about 2 weeks ago, I keep getting disconnected from games that I play. It will boot me off of the game but I will still have internet access. I've tried upgrading the firmware, had linksys techs resetting the router, gotten a new modem from my ISP. Hardwired the PC that I normally use.The router that I have is a WRT120N, each and everytime a linksys tech reset it's basically the same thing with the same disconnecting problem afterwards. I'm thinking it's usually when another phone device tries to connect to the wifi that it boots me off. I have 2 pc's, one laptop and my iphone that connects fine w/o any problems but when another android or iphone connects it causes me to disconnect.

TP-Link ADSL2+ Wireless :: TD-W8970 - VPN Disconnection But Tunnel Still Shows As Up

Apr 15, 2013

Region : United Kingdom
Model : TD-W8970
Hardware Version : V1
Firmware Version : 0.6.0 1.2 v000c.0 Build 130201 Rel.54921n
ISP : O2

I have sent the following trouble ticket to TP Link Support hoping they can shine some light/fix a VPN issue I am experiencing with the TD-W8970 router.

Please see the text below.........

I have 2 tunnels set up on my TP Link TD-W8970 and although both of these work for a a while, they both drop out after 24-36 hours for no apparent reason. The tunnels still show as "up" in the router, but I lose PING and connectivity to my remote systems. The only thing that seems to fix this is to reboot the router.

I have tried the tunnels with and without "DPD" (Dead Peer Detection) enabled and the results are the same.

I have 2 other friends who have the exact router with the same firmware (latest version), and they too have the same issue.

There is nothing in the logs showing any disconnection of the VPN, and as I have mentioned, the tunnel still shows as "up" on both ends. Its almost as if the service has stopped running, but I cannot check this.

I currently have an AE2500 wireless usb plugged into my pc which is upstairs from my modem NetGear CG3100.Everytime I establish a wireless connection it has 4-5 bars of signaltivity. However after a couple of seconds the signal  bars drop to 2 bars and maintains that way. I then experience disconnections which sometimes if i disconnect from the web, my browser detects it as a DNS error. To overcome this i just disconnect from the hotspot and reconnect again but the problem still persists.

Cisco Wireless :: WLC 5508 Management Interface Connection

Aug 1, 2010

I'm setting up a new 5508.  I've used the config from a 4402, have successfully connected to the Service port to manage the device, but for some reason cannot connect to the Management interface.  In this case, port 1.
 
The service port is connected to a Catalyst switch and grabbed an ip address (10.2.x.x subnet) no problem.  I can access the 5508 via https using the SP.  However, port 1 is connected to the same Catalyst switch, but on a different vlan (subnet 10.20.x.x).  Both ends show that the interfaces are up, I can ping the interface from any other host on the network, but when I try to manage the device via https I cannot connect.  We are using WCS and I cannot add the device from the WCS.  About all I can do is ping that interface.

Interestingly the issue was resloved after i Resetted All the LAPs again. (all 14 of them worked fine after the reset , but there were no prior configurations on the LAPs , they were just opened From The Box).

Netgear WG111v2 Frequent Disconnects From Wireless Internet

Jun 12, 2012

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.
