Any issues on Cisco ISR / ISR G2 routers running 15.x code while doing NAT for large quantities of users (3000+) involving lock ups? This seems to be an ongoing issue for a customer. The symtom is present on 2811, 2911 and a 3945. The 3945 never spikes over 10% processor or memory utilization, yet still has these issues. The routers have been tested running 15.0(1)M5, 15.0(1)M7 and 15.1(4)M4 which all showed simular results. Other router side services are running such as NetFlow v9 to two destinations. Another interesting symtom, doing a "show ip nat translations" command will crash the router if executed at its peak usage period. NAT is to a single IP (sourced from outside interface), not a pool.
i have here an cisco 881 router which has been in service for about 3/4 year now.yesterday the device from one moment to an other stoped working the device does not respond on console, it does not boot (or seems to be booting) and is also not responsive on the reset hole.
powercycle has been attempted but without result. the only evidence that it is alive is the FA leds. they are all constant on.
I have 20 to 100 Mbps(FTTH) line at home. I am planning to put few servers online to serve web pages. I have tried them taking online with normal home dsl routers, but router hangs very frequently.
I have a cisco router 1811 when powered displays the output below then it hangs at that point.

i have a cisco router 7206 ,when i create subinterface with ip , the router hangs , and all interfaces are down ,i just remove interface gi0/1 and plug it again, what is the relaiton between subinterfaces and hanging routers> the problem occurred when i configured sub-interface on GI0/2. [code]
The Cisco 3600 series (3640) is hanged during booting proccess, the IOS is decompressed, but after some text it hanges and I even cannot go to user exec. ROMmon and bypassing the config setting, but the result is still the same.
The router had firmware 2.0.x(?) and I tried to update to the latest FW, according to the webpage that's
FW_E1000_2.1.02.006_US_20130115.bin
Hardware is E1000 v2 according to sticker on back.The firmware update failed (no reason given) and the router now hangs in limbo where all it does is flashing the power LED.I set my PC to 19?2.168.1.2 and TFTP'd the firmware over to 192.168.1.1 - no errors reported and 192.168.1.1 is pingable. Held reset for 30s, then powered down the router for another 30s. On power-up the router still flashes the power LED.
Yesterday my router was hangs and my services was stuck. I start the router hard booted and it works fine.This was second time i was facing this kind of scenario. The attached are the "show tech support" of the cisco router 2821.
Have been trying for the past two days to install a new E4200. It gets to 25% in the setup and then errors out and says I need to contact customer service.
Connecting through a brand new DSL modem that I know works as I can get access through my old router.
My PC (Windows 7) is directly connected to the router. I got to the point where I named the router in the install process the first time, but then it hung.
Have tried to use the CD to re-setup with no success. I've tried the hard reset holding in the button for 10 seconds and unplugging but nothing has changed.
I have 2 X E4200 router, one is directly connected to the internet and the other is in the bridge mode connected to the first router. I have apple TV connected directly with the bridge router on one of the Ethernet port.I notice that when you start apple Airplay mirroring on the iPad2 both the routers will hangs with no reason and the only way to fix it is to reboot the routers. I have reset both the routers to factory default twice they both are running firmware 1.0.03 build 14 .
We bought a cisoc 2911 Router with an EHWIC-VA-DSL-A Card. I did the Dialer Setup without any problem but if i set the ATM interface with the commands: [code]The Router crashes after some seconds. I didn't connceted the phone line to the DSL card. [code]
I have been through three chat sessions on this without resolution and support tells me just to factory reset. After some time (weeks) after a successful local login to the admin page subsequent attempt to login just hang. After entering the admin password the page changes and says "Waiting" under revolving circles. It will sit there for over 1 hour. I have tried IE, chrome and firefox on Windows 7 and Windows 8 on three different machines and it behaves the same. Of course I have to go through this same process with the support people every time and every time they come to the conclusion that I have to do a factory reset. But so far Linksys denies that there is a defect.
recently i bought a x1000 for my home network. I use the x1000 as router an wireless accessPoint between my WAN internet uplink an my home network...yesterday the router hang up completely. internet stoppp working. so i tried to access to x1000 to check if PPPoE connection was still active. But it did not load the webinterface. I tried to connect over WLAN and LAN. Both not working!
E3200 firmware 1.0.03 build 9. HP 1012 attached to USB port of the router. On a PC with Win7, Print Preview hangs in all applications. Print... also hangs in all applications. Reboot, re-installation of print driver, change default printer do not fix.
I recently upgraded my internet speed service from my ISP (Brighthouse). They installed a gateway to replace their old modem, but I have had it bridged so it should act as a modem. Speedtest.net shows downloads on the order of 40-50 Mbps and uploads around 5 Mbps. If I try doing something interactively that pushes the speed and size of files (like flying over Google earth using my mouse to guide the direction and speed) my connection seems to hang. I have to reset the router (unpower and repower it) to get my internet connection to work. This has also happened when I quickly downloaded a series of large images - I click to get the next page fairly soon after the current page has finished downloaded. My router is a WRT350N.
I have two mac laptops and am trying to copy a directory with a number of PDFs in it. The files aren't particularly large, but there are many of them. At some point in the process the router stops and must be turned off and on before it will respond again either wirelessly or wired. I have tried the same experiment with both devices wired and the router works fine. I have tried changing the MTU, channel, beacon setting, etc. as other forum posts have tried. I tried reflashing the firmware, resetting to factory defaults and reconfiguring. So far no success. Cisco support wants me to return the router. Frankly I'm at the point of considering the former Linksys/Cisco products complete rubbish. I am going to have to buy a new router even if I return this one since I can't be without a router for any length of time.
I saw a thread from early 2010 which described the issue I am currently having to a T. I am on a Belkin Wireless G with Mimo router and it runs perfectly either on LAN or WLAN, until my new roommate's MacBook gets on there at the same time. As soon as the MAC connects, I get a blue screen of death and the PC restarts. I have been battling this issue for over a week now and have absolutely narrowed it down to the Mac/wireless area.
I have already uninstalled/reinstalled my wireless drivers and thought that had fixed the issue(it worked fine for 4 days), until the roommate returned from out of town and connected the Mac to the Wireless....then WAMMO, like clockwork, back came the BSoD. This seems like a very unique problem, as I have done many searches online and the one I mentioned on here is the only one I could find that accurately described my issue.
For reference, I have posted the link to the previous case below. Unfortunately, no solutions, other than reinstall drivers (which I have already done) are posted. I tried everything in that thread and my settings appear to all be the same as his. Is it possible this is just some rare Windows 7 glitch that has never been resolved?
New Cisco E2000 (wireless N router) not compatible with WMP54G (2.4GHz) adapterCan't find new drivers. Crashes computer to blue screen. Can the two be made compatible? Windows XP Home and Pro (both computers have WMP54G and blue screen).
I have a wgr614 V6 router, yes its old. I had 3 devices connected to it just fine before without any issues. But now It only allows my laptop, when I try to connect with my ipod touch or desktop, not only does it fail, the entire network crashes and my laptop loses it and its gone. It then takes about 2 minutes to come back up. So whenever I attempt to connect with another device the network crashes. so right now only my laptop is connected.I downloaded & updated to the newest firmware, did not work.I tried resetting the router, and made the network all over again, did NOT work.
I have a D-Link DIR-615 router, hardware version E3, firmware 5.10
When I go to get a list of servers when playing games online, my router lights up and then crashes, and I cant get on the internet again until I exit the game. Although, some games do work. There are no problems with my firewall, and if I connect directly to my modem, I can play fine.
I recently upgraded the firmware from 2.0.2.1 to 2.0.3.3 and when the router rebooted the interface was missing many items. On the basic setup page the boxes were missing to set the local ip address, subnet mask and anything below that. On the Wireless Security page the security mode box was half it's size and did not have any options in it. The wireless isolation wpa algorithm, preshared key and key renewal boxes were missing too. I rebooted the router and still got the same thing. I was able to get into administration and reset to the factory default. Once the router rebooted I was unable to get into the interface at all. It wouldn't come up at all. The power and light were blinking but I was unable to connect to it. I tried to connect with 192.168.1.245 and the one I had set manually but no luck with either. I was able send back the router for an exchange with Cisco. I received the new one today. It started up and everything worked great. I decided to try the firmware upgrade again. I went from the firmware version that was on there(I didn't right down) to 2.0.2.1 and the upgrade worked as the other 3 I have. I than tried the 2.0.3.3 upgrade and I got the same thing as the other router I sent back. I have 3 other routers in place that I will not be upgrading at this point. I should not have tried the upgrade again on the one today but being a bank the examiners like everything up to date and it's part of the monthly check.
I seem to be experiencing a problem with content filtering on our 1941, if I add anymore patterns to the policy below the router crashes and requires a reboot, not sure why?
parameter-map type urlfpolicy trend cptrendparacatdeny0 max-request 5000 max-resp-pak 1000
Essentially when my friends computer disconnects from the router, everyone elses computers cannot access the internet, even though windows says they are still connected.
I have just bought an X1000 box, it seems to be randomly locking up and the only way around the issue is to reboot. I have also noticed it can't seem to handle streaming video either.
My ADSL has been checked and all is OK and if I don't stream video generally things seem OK for a couple of days. If I run a continual ping to the unit you can see that now and again the request times out but then some times comes back and other times I need to reboot again. The log file seems to show very little either.
In hopes of fixing some "flaky" connection issues with my WRT54G V2 Wireless Router, I downloaded and applied the new firmware version released on 08/18/2011, Ver.4.21.4 for my Version 2 Router. I downloaded, went through the application process using the router's firmware update process, it said it was successful and then the router restarted and didn't work. Couldn't ping the address, constant flashing Power light, no response at all from router. Tried again, same result. Performed hard reset, same result. Tried a few other recovery techniques found on the web with no success. Finally I did the process found here [URL] This reset the router and I re-uploaded this same 2011 version. Router still broken. I ran through the process again after downloading an older version of the firmware, specifically version V3.1_4.00.7, the upload ran, and the router worked again! This was proof to me that the newest version completely BRICKED my router. I'm so relieved I was able to reset the router and manually recover, but most will never try this. I recommend Cisco retest this ASAP and pull the new release for the V2 router until they get this resolved!
I purchased a WRT160N router last Friday. After setting it up, everything seemed to work fine, but after a couple of hours, the router stopped responding to any requests. The LEDs stayed on as if nothing had happened, but the router was dropping everything coming from both the WAN and a wired LAN interface. Since than, I had to restart it 3 times during the last 3 days.The firmware is 1.53.0, which seems to be the latest firmware for the European market - even when I try to get a newer firmware, this site only offers the US version 1.02.2.Should I update the firmware to the US version 1.02.2 ? Is there any difference between the 1.53.0 and the 1.02.2 version ? Is there a way to restore the original firmware in case the update fails ? I haven't found any link to 1.53.0 version..Also, does this firmware updating affect my warranty ?
I am attempting to setup a wireless access pointand want to deny access to a group of IP addresses. When I go to Wireless, MAC setup, Deny or Allow, and select "Edit MAC Address List" my browser crashes. I have tried this on two different Linux systems and three browsers, Firefox, Mozilla, and Seamonkey.Tech Support tells me to downgrade to Firmware version 4.30.2, the only compiled version available on the Linksys website, but with no way to go back to 4.30.5 if the problem isn't fixed or if worse problems come up I am reluctant to try this fix, The only other suggestion Tech Support offered was to replace my WRT54GL with a WRT54G.
My WAG320N has developed a fault where by after 1, 2, maybe 3 clicks on the web interface and the router reboots. The browser can no longer connect until it is closed and reopened (firefox). Firmware is: v1.00.12
Interestingly, if I use a different browser it doesn't seem to reboot and I can click away for ever. However, firefox reproduces the problem every time. FIrefox version is 7.0.1

For a while now, my wireless network at home has been very unreliable. I posted on these forums before, asking for assistance to fix crashes that seemed to be random. I was largely unsuccessful, and the problem continued. However, as I continued to experiment with different methods to keep my network up and running, I noticed that as long as I had at least one device connected to the network around-the-clock it never crashed. This was easy enough, as I own an iPod touch and a dock (I would leave it sitting it the dock unlocked all the time). But it's annoying to never be able to leave the house with it, and I'm ready to finally get a solution to the problem once and for all. I would prefer not getting a new router, but if worse comes to worse I will.
To sum it up: -Works perfectly (when up) at full speed, never crashes unless there are no devices connected to it. -When it does crash, it is very difficult to 'coax' it back into working again; it's been down for weeks at a time before. -For some strange reason (and maybe this is a clue), newer game systems such as a Nintendo DSi or PS3 can make it start working again. I, of course, own neither of these. -I'm using a WRT160N V3, latest firmware as far as i know.
