Linksys Wireless Router :: E1200 Drops Connections At Random Intervals

Jun 29, 2012

Router is connected to my ISP with the option Keep alive and redial value of 20 seconds (the lowest i can set). There are two distinct problems: Router drops connections at random intervals. It can happen once a day or several times a day. It always happens overnight (so every morning it isn't connected). This doesn't seem to be related to ISP as direct connection to computer is stable.The Keep alive option isn't working. When it drops connection it isn't trying to re-eastablish it for at least 2 minutes (the longest i have waited so far, 6 times the redial value configured). Producing external traffic (e.g. constant pinging of some host by IP address, refreshing some web page) doesn't work. When i log on to admin console (browser based) simply clicking connect button brings connection back online. I've even been looking at status page constantly refreshing to see if it ever made a single attempt and it appears it didn't.I did my "homework" before posting (upgraded FW to 2.0.02 build 3, finetuned MTU).

D-Link WBR-1310 Limited Access At Random Intervals

Jan 18, 2012

I have a WBR-1310 router that for the past few weeks has been giving me 'limited access' issues at psuedo-random intervals. The router functioned perfectly for a long time, I dug it out of storage about 8 months ago, and up until Christmas it was working fine, then both my roommate and I got tablets. Now our router is supporting 6 devices (PS3, 360, lappy, 2 tablets, smartphone) and occasionally more (other peoples phones, roommates laptop once he gets it repaired). However my research online has led me to believe that I should be able to support near unlimited wireless devices on the network (though effectively only around 30). Still, these extra two tablets are the ONLY change to the network that happened immediatly prior to this problem starting.Now I find that when I'm home alone I can go for the whole day with no network issues, but as soon as my roomy gets home and starts to use his devices the network craps out. unplugging the router and modem for 30 seconds fixes the problem temporarily, though the time before it craps out again ranges from hours to minutes.

I CAN plug my lappy into the modem directly when the router is not functioning and still have internet access, so it's definitely the router with the issue.All devices except for the PS3 are using wireless. I've done a hard reset to the router and set it back to factory settings on two occasions, I've changed the SSID and passphrase to get others off the network, I've changed the security type twice, I've tried some suggestions for similiar problems online such as enabling 'gaming mode' on my routers homepage, and setting a custom IP address (I used 10.0.0.1).Over the last 72 hours or so (the problem has existed for a few weeks) I've also received a few messages about my laptop having an IP address conflict; unsure if that is related, but I'm still able to access the internet when I get that message (albeit slower than average) [code] I will update this with another ipconfig the next time my internet dies; which I'm sure will be sometime today.

Wired PC Randomly Disconnects From Network At Random Intervals?

Feb 11, 2013

Wired PC randomly disconnects from network at random intervals each dayoday it has done so 3 times. The only way I have found to get it working again is to reset the router which can be inconvenient. When it disconnects all wireless devices continue to work and I have no issues like this with my wired consolesI switched to using a static IP address, since having an automatic one gave me the same results [i have since switched back to automatic]Be happy for any suggestions on how to sort this. I am using W7 OS and I'm using an Orange router. I don't know if its relevant, but when I go to reset my router I have noticed that the download light on my router is flashing like crazy when my PC has disconnected.

Cisco AAA/Identity/Nac :: ACS 5.2 Hangs On Connecting With MS AD At Random Intervals

May 30, 2012

I have a simple ASA, ACS, AD schema for RA VPN authentication. All is working for a few months now, but since the initial deployment we have this connectivty issue regarding ACS and MS AD. At random intervals, 1 month/1 week, the ACS connection status becomes "DISCONNECTED" although the CLI shows that ad client is running. But because of that, no RA VPNs can be authenticated. Clock is not a problem, since it didn't change automatically nor was manually configured prior to the malfunction.

Cisco Routers :: RV220W Rebooting At Random Intervals?

Jan 27, 2013

our RV220W router has been experiencing random reboots throughout the day, causing a network outage for our local network for the few minutes it takes for the router to start up again. We've seen it reboot at least 5 today alone (and the time is currently just a little over 1pm).I'm having trouble finding the reason for these reboots in the router's logs, although I find these two lines repeating in the error log:

Mon Jan 28 13:20:52 2013(GMT+0100) [rv220w][System][EVTDSPTCH] umiIoctl (18, UMI_CMD_DB_UPDATE(4)) failed. table=dot11STA row=11
Mon Jan 28 13:20:52 2013(GMT+0100) [rv220w][System][PLATFORM] /pfrm2.0/bin/bwLimitConfig /tmp/system.db 18 dot11STA 11 failed. status=-1

I'm not sure why these messages pop up, since we're not using the bandwidth limiter module of the router (granted, we do use QoS profiles to ensure our own LAN is prioritized over the guest VLAN). I'm also not sure whether this is related to the router reboots.
 
I also find the following repeated line in the warning log:

Mon Jan 28 12:50:50 2013(GMT+0100) [rv220w][Kernel][KERNEL] ERROR:endChantRecv: protocol PNAC returned !OK 

The router is currently running on firmware version 1.0.4.17 (latest official release), since we needed support for hairpin connections (as I found out in a previous thread of mine). I've seen the suggestion of downgrading to a previous firmware version in another thread, which has possibly solved it for the poster in that thread, but as we really need the hairpinning support, I don't know which firmware version is safe enough to downgrade it to, if needed.

Internet Running Fine But At Random Intervals Not Send Or Receive Any Packets

Jan 26, 2011

I've been having this problem on my desktop and it's really annoying when i try to play online games that need a constant connection.I have Windows XP and i'm using a wireless connection via a wireless USB adapter. The problem is that the internet is running fine but at random intervals it starts to not send or receive any packets. This will usually cause my to disconnecting during a game causing other players inconvenience. After I d/c the internet will usually take 5-30 seconds to start sending and receiving packets again and regain connection.

Linksys Wireless Router :: E1200 Changing Out Ethernet Cables / Checking Connections

Apr 25, 2012

ISP : Charter Communications
Modem : Motorola SURFboard SB6121
Router : Linksys E1200
 
I started out installed on the CD and then I kept getting messages about not being set up and finally it kicked me out. So I started out with the basics, changing out ethernet cables and checking connections. I then tried cycling the modem, router, computer and still no go. As soon as I plug the modem straight back into the computer it kicks back on. So then I tried some other trouble shooting ideas on the forums with the last being MAC address clone, save changes, release renew IP, and finally another round of cycling and I still can't get it to work.

Linksys Wireless Router :: E1000 Drops All Connections Every 30-60 Minutes?

Aug 26, 2012

I recently bought a refurbished E1000 wireless router from Amazon, and from the first day I've had recurring connection issues with it. Every half hour or so it will lose all of its connections (wireless and ethernet) and requires a hard reset. After resetting, all connections are good for a little while but then the problem occurs again. When plugged directly into my modem (Motorola SB6121), my internet access is completely fine.
 
The router has the latest firmware as far as I know (2.1.02 build 5 May 6, 2011), and I've tried to change several settings (MTU to 1400, Fragmentation Threshold to 2306, etc) but to no avail.

Linksys Wireless Router :: E4200 Constantly Drops Connections

Sep 5, 2011

My E4200 seems to be dropping connections throughout the day.  For wireless it'll still show full signal and connection, but there will be no internet activity for about a minute.  Then after a minute things will work just fine again. For wired I notice it in my XBox mainly when I get dropped from games as constant as the wireless drops.I believe my modem isn't the problem since the old router never dropped connections on the hard wired devices.  Occasionally my old D-Link router would drop wireless, but never this frequent,I am running 1.0.02.  I've rebooted the router/modem several times.  I even reinstalled the entire setup with the current version of Cisco Connect as the tech person suggested, but still no luck.  The first week or so using this router was flawless, but ever since then it's been dropping connections several times throughout the day to any device connected (wireless or wired).  The problem seems that the router just hiccups the connection very quickly, so quickly that Windows doesn't even recognize the connection has been lost, but long enough to drop a multiplayer game on XBox or to have me mashing refresh on my internet browsers.

Linksys Wireless Router :: E3200 Drops Connections After Firmware Upgrade?

Jun 5, 2012

I have a E3200 and upgraded the firmware last weekend to 1.0.0.4 and now I get dropped connections every few minutes.  I was working form home and VPN into a west coast client and was getting dosconnected every few minutes so I thought it was possibly their VPN but when I checked my outloook it was also disconnected and is not associated with their VPN.  I called Comcast and they said the modem has been online for 19 days so now everything points to the router.

Linksys Wireless Router :: E 2000 Drops All Connections When Connected With 4th Wire

Sep 2, 2011

The router works fine until I plug the 4th wire in the back, which goes to a 2nd desktop computer, then it is only a matter of time until the router drops all internet connections including the direct wire to desktop #1, wireless, and the other two wires.This is my 2nd e2000 router since Amazon replaced the first one after about 4 months as it was having the same problem.

Linksys Wireless Router :: WRT120N / E1200 - Extend Home Network With Both Wired And Wireless Connections

Jan 27, 2013

I am trying to extend my home network into my basement with both wired and wireless connections.  I have a WRT120N upstairs, which is connected to my cable modem.  I have an E1200 in the basement, which I have connected with a LAN port.  DHCP is turned off, and all wired connections are getting an address from the upstairs router, and connecting to the internet successfully.I've configured the wireless with the same SSID on both routers, but the clients that connect to the downstairs wireless are not able to access the internet.  They are getting an IP address from the upstairs router, but can't get past the gateway.

Draytek 2830n Router / Wireless Connection Drops Out At Random Sometimes

Jun 14, 2011

I'm having some rather odd issues with my wireless connectivity. Running a draytek 2830n router. The wireless connection drops out at random sometimes, at other times it connects (shows full reception) but does allow any kind of internet connection. Plugging in by lan cable allows normal function.I have no clue whats going on but I did just notice that shutting down one of the laptops connected to the network (Dell lx502) appears to have solved the problem for the moment. I've not had a chance to test this as a long term solution. However I believe this is the only laptop with a dual band wifi card.This problem was also occurring on our previous router, a draytek 2820vn but the symptoms were a bit different and this laptop was not there at the time.Is it possible for one machine to knock out an entire wireless network? The other change I made yesterday was to activate the bind ip to mac function on the router for our new NAS as I was messing around with ftp configurations.

WRT54GL Router Drops Wi-Fi Connections Frequently

Mar 6, 2013

I have a WRT54GL that I bought about 2 months ago, and I've had nothing but problems with the wi-fi since I started using it. It works as normal about 90% of the time, but usually 50+ times per day, I won't be able to connect to the router wirelessly (with ANY device, no matter how close I am to the router) for 1 to 2 minutes. The fact that I can't connect to the router with ANY devices during these times leads me to believe that the problem lies with the router itself. Another thing to note is that the wired connection to the router works just fine during these wireless outages.

I've tried changing channels and upgrading the firmware, but nothing has changed. Did I just get a bad router?

Connection Intermittently Drops At Random Times

May 9, 2012

We recently moved and upgraded our internet service from 1.5 Mbps to 4Mbps with CenturyLink. However, since our service was activated last Thursday, the internet connection intermittently drops and will not recover unless I reboot the modem. The period of up-time will last anywhere between fifteen seconds to several hours, usually falling along the five-to-ten minute range. No difference when using ethernet/wifi. The DSL light stays on, and the Internet light remains on as well.

D-Link DIR-655 :: Wired Connection Random Drops?

Apr 12, 2011

I should start by saying I am no novice when it comes to networks but this router has been nothing but a issue since day one.

*The Setup - 2 wired PCS, 2 Wired Macs, 1 Wireless Iphone, 1 Wireless Ipad.
WPA2 Only / AES key, Channel 6, G/N only, Hidden SSID.

*The Problem - 95% of the time the wireless and wired is running fine. However, Sometimes randomly webpages on the computer will stop loading... but heres the kicker... other internet connected programs like Ventrilo, or torrents, or games will still be working and running from the net like there is no problem. When this happens the internet browsers on the macs and PCs will say page cannot be displayed instantly. Happens to all computers at the same time. After about 10min the webpages will load again. I have 16mbs internet and while this is happening my games and voice chat programs do not go up in ping at all.

I have turned off QoS since that made the most sence... but other then that I have no been able to figure it out. I even turned off wireless while it was happening and it still didnt fix it. A sure fire way to fix it is to restart the router.

I am 100% stumped. Do I just have a bad out of the box router? it is only 2 weeks old.

Motorola Surfboard Sb5101 Modem / Random Connection Drops?

Mar 5, 2011

I have a Motorola surfboard sb5101. Provider is comcast.I have never had any problem with my equipment until now. Here is whats going on. I bought a used sb5101 a week ago so that I would not have to pay the rental fee anymore. Comcast activated it, and it worked fine for a week or two. The other night I got disconnected from XBOX live randomly in the middle of a game. Thought maybe just a hickup, no biggie. Well it happened 3 more times in a few hours, then again the next day.So thinking maybe this used modem is bad, I plugged back in the rental from comcast which I still had. Worked fine for a while, then the same thing, random dissconnects after 10 min, 30 min, 2 hrs into a game...etcOn both modems, the 1st and 4th green light are solid, the 2nd and 3rd green light are flashing when the connection from LIVE drops.So I'm starting to think know that neither of the modems are bad. I then try going directly to the modem instead of the router, never had any problems with the router but figured I try.I even went into the attic and got rid of the 4 way splitter that feeds cable into all the bedrooms and put in a 2 way instead hooking up only the cable line im using for xbox. Thought maybe the signal is getting degraded to bad, eventhough never had a problem before.So now I'm practically hooked up right to the line coming off the street, ethernet cord plugged directly into the modem, no router. Still dropping connections randomly with same 2nd and 3rd light flashing.The connection needs to be completely stable for multiple hours.Also, I called comcast when I had to reactivate the rental modem, so they did refreshed that modem and reactivate it, but still had the disconnects the next day.

Cisco VPN :: 2921 - IPSec Tunnel Random Packet Drops

Mar 15, 2013

I'm trying to troubleshoot a random packet drop issue for an IPSec tunnel between two VTIs. For over a month, we didn't see any issue, and starting today, we have up to 30% packet loss across an IPSec tunnel.
 
After some analysis, I concluded that the packet loss happens somewhere on the path from the uc520 to the 2921. Packet counts show up correctly on the uc520 physical egress interface, but the packet count is low on the ingress interface on the 2921.

Pings outside the tunnel along the same path are fine.
 
I also cleared the tunnels on both ends and after they reestablished, the issue was still present.
 
Any pointers on finding where the packets get lost?

2wire 2701hg-b Wireless Drops Connections?

May 26, 2011

I have a 2wire 2701hg-b wireless router/DSL modem. Every once in awhile, my wireless devices all lose their connection to the router at the same time. I believe the problem is internal to the router/modem as all my wireless devices' connections are dropped at the same time AND I can only get them connected once I disable and then re-enable the wireless on the router. The problem seems to only affect wireless devices as all my wired devices remain connected and my Internet connection remains intact as well.

Linksys Wireless Router :: Random Disconnections For Wrt54g2 V1?

Jun 12, 2012

this had happened for a few months and i did not really mind until the disconnections worsen. usually when i power on the router and started using the internet, it will disconnect randomly once. my wireless SSID will disappear and lost connection. and no matter how i refresh the SSID still won't broadcast.
 
the only way to get back internet access is to re-power on the router, so the SSID will be broadcasted again.
 
my wrt54g2 V1 router had recently upgrade to the latest firmware version,1.0.04.  but still disconnects as usual. however the disconnections only happens once, after u re-power on the router, you will not disconnect again.
 
but after turning off my laptop, and use it again after few hours, the same thing will happen again, a random disconnection and got to re-power on the router.

Cisco Wireless :: WAP200E Access Point Drops Connections

Aug 18, 2012

I purchased a Linksys WAP200E Wireless-G Exterior Access Point – PoE and a HGA9N (9dBi) High Gain Omni-Directional Antenna through CDW Canada about three (3) years ago in April/2009. The first year it worked great and gave complete coverage throughout the Campground. The second year it started to become increasing less coverage and now in the third year, it has very poor coverage. I have purchased and installed a new Microcom HG2415U-PRO (15dBi) HyperGain Outdoor Omni Directional Antenna. This has NOT made any improvement so I am now thinking that the WAP200E Access Point is the faulty equipment. I have changed the channel to number 11 and still no improvement. The Signal Strength is only Good and then dropping to Fair and sometimes no signal at all. This is from a line of sight location that is only 60 yards (180 feet or 54.9 metres) away. There are no objects between the Antenna and the computer.

Linksys Wireless Router :: E2500 Reboots At Random Occasions?

Jan 1, 2013

I have a E2500 router that until recently has been working fine, the router currently will reboot at random occasions. I have tried resetting the router to factory defaults to test if the firmware was an issue but both the factory default and the most recent firmware build(1.0.05 build 2) offered on the download support page. I have tried 2 different AC adapters to test power and two different Cat5 cables so hard ware wise everything is looking good. I am concerned that it may be an issue still with firmware or with the cooling fan and the unit may be overheating.

TP-Link 150Mbps Wireless :: TL-WR741ND Drops All Connections (wired And Wireless)

Mar 31, 2013

Region : Argentina
Model : TL-WR741ND
Hardware Version : V4
Firmware Version : 3.16.4 Build 130205 Rel.63090n
ISP : Fibertel

My TL-WR741ND is about 1 year and a half old, it was working fine until about 2 weeks ago. I need to reset it, times between resets is not consistent, meaning, it can take 30 minutes, or 8 hours, but it needs to be reset. Right now, there are 2 wired connections (PS3 and Desktop PC) and 7 wireless (4 cell phones, 2 notebooks and 1 netbook). 1 of the notebooks has static IP, and it also has a VM running, with another static IP. Also some port forwarding simply stopped working (ports 80 and 1180), the rest of the ports work flawlessly, but trying to forward the port 80 and 1180 (to the 2 static ips) won't work. I already upgraded the firmware, and the problem persists, also changed the channel (from 6 to 1, and then from 1 to 11).

Installing dd-wrt/openwrt/gargoyle or anything like that, is not an option. The only reason why I bough t this router, was because I could use dd-wrt, I installed it 1 year and a half ago, and it simply sucked, the wireless bandwidth was non existent, and it was a headache. I installed it again last week, to see if it could be a solution, and I was not even able to save changes in the control panel. I need a real solution, and installing a firmware that works only on chrome is not an option (specially when I use Firefox, and I needed to install chromium just to erase dd-wrt)
