Cisco WAN :: 2911 Router Hanging / Freezing At Random Times
Dec 16, 2012
I have a 2911 router hanging/freezing at random times, could work fine for a week then crash, or sometimes, could only go a few hours, completely random with timing. The onyl fix is to manually pull the power and reinsert.When this happens, all services/access stop working, including nothing on console access.This was on 15.2.1.T1 which im aware, has a few bugs, so i upgraded to 15.2.1.T2.The issue continued, so I swapped out the 2911 with a brand new one. The issue is still present.
One interesting thing, is when the router crashes/freezes, all lights appear to remain on working as usual, but when i unplug any of the ethernet links, the lights still continue to remain flashing and on for the ethernet LEDs, even once i have fully removed the cat6 cable.

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

The router is being good so far. I have a Belkin Wireless G Plus MIMO router with windows XP operating system. This has been going on for a couple of weeks now and I really want it to stop because it is stopping me from doing things that require the internet.

I am having the same exact problem with the random freezing. I used to be sponsored on Xbox 360 for call of duty black ops and my mom met this guy and i had to move into his house, So now i had to drop my sponsorship and everything because i randomly freeze for about 3 seconds and then unfreeze and i jump forward and catch up to what apparently i was doing but not doing on my screen. It even happens on world of warcraft on my computer and it is very aggravating to have to deal with. And just like Cassius is saying "the ping spikes ruin online gaming entirely and tbh."

We have a RV082 V03 being used as a gateway that was bought in mid 2011. The firmware version that came with it was v4.0.0.07. Up until we upgraded to firmware v4.2.1.02(Upgraded in Jan.2013), we would have to restart the router once every month due to loss of internet connectvity and it locking up. After I upgraded it to the 4.2.1.02, it gradually starting increasing from rebooting the router once a month, to once a week, then to multiple times a day. Today, I upgraded the firmware to the latest version being v4.2.2.08 and it has not froze up since the upgrade, but then again, it happens randomly through the day so it might not happen until tomorrow morning so we will see how this goes. During the time when it looses connectivity, I CANNOT get to the web gui or even ping the RV082 device. The lights on the RV082 are blinking like it is working though.This router is not even 2 years old yet and cannot believe that it would be dying already.

I check all of the settings and changed the channel to see if it works. For some reason it disconnects my wireless internet at random times and i know before it never use to do that before with a older router. There is nothing blocking it, it worked before, and my computers can connect except two. The only thing i can guess is my wireless card.

The wireless drops specifically from my laptop constantly at random times. When the wireless drops in order for me to be able to reconnect i have to restart the router itself. There are also random times where the Wi-Fi stops broadcasting altogether. I have a computer connected via Ethernet and it does not lose connection during these times. All the computers are running Windows 7 and the Router is up to date on firmware.

Had an E4200 for a couple of months now and have not been able to resolve an issue with the router dropping an Apple iPad 2 at random times.The E4200 is replacing a Cisco Aironet 1200, which never dropped any clients, iPad 2 or others, and never displayed any of the issues below.
TECH DETAILS:The E4200 is being used purely as an access point. All extras are not in use and are disabled.
Firmware 1.0.03
Hardware version 1.
BASIC ISSUE:The E4200 drops an Apple iPad 2 off the 2.4 Ghz Mixed (B, G, N) network. The user must then select the network to rejoin. Rejoining occurs without incident. The same issue occurs when the network is restricted to B, G. The drops occur at what appears to be random intervals - sometimes 10 minutes apart, sometimes hours apart. We can have as many as 6 drops in an hour. A ping to the apple ipad shows the device stops responding to pings about 10 seconds before the user is prompted to rejoin a network. Meanwhile, a ping to the E4200 itself from a laptop connected via the E4200 on the same radio as the ipad continues to work without fail during this incident.
1. The iPad 2's cannot connect to the 5Ghz radio. I believe iPad 2's are supposed to support 5Ghz.
2. Both our Apple TVs do not connect to the 5Ghz radio: they fail with a "There was an error connecting to the network. Check your settings and try again. (-3914)" error. Apple TV supports 5Ghz.
3. The admin interface for the E4200 is very slow sometimes. Probably over 20 seconds to render some pages when it gets really bad. As a comparison, Internet-based pages on fast sites that delivered via the E4200 itself load in less than 2 seconds.
4. The HTTPS version of the admin interface can only be connected to via Safari browers. Both Internet Explorer 9 and Chrome 16 fail to connect with a "Connection reset" error. In Chome, it says "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." This is across multiple devices. There is no issue with straight HTTP.
All other devices - including Macs and PCs - connect fine with the E4200 on both 5Ghz and 2.4 Ghz radios, even if they cannot access its admin interface via HTTPS.I've presented quite a few issues above, but the main one is the drop outs for the iPad 2 devices. I'd present logs on drops, but the thing doesn't record any useful logs.
Basic wireless config:
5Ghz:
Network Mode: Wireless-N Only
Channel width: Auto (20 or 40 Mhz)
Channel: Auto (DFS)
SSID Broadcast: Enabled

I have fiber optic Internet with static ip and keeps disconnecting at very random times. It started 3 weeks ago, before it worked perfect. Most of times dcing 3 times per hour. But sometimes working for hours without dcs. Usually disconnects only for half minutes then reconnect, it can be very annoying. The provider keep saying that need change router. I'm tried three different of routers already, but keeps disconnecting. I'm tried connect the net directly into my cpu, without router, but not worked, dc-ing too. I tried ping the default gateway when its disconnected, and its saying: request timed out.What else can i try? It should be, that the provider has too many clients, and their router collapsing?

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.

I have a brand new Dell laptop running windows 7 connected to a sky router wirelessly. My internet connection randomly just drops. At 1st I could just click on the yellow triangle and troubleshoot and it would reset the network adapter. I cannot do that now - Im having to disable the adapter and the enable it and Im back on the internet.I have set it up so I am connecting via a manual IP address as I wondered if when the kids PS3 was connecting it was pinching my Ip address.

I've been having some problems with my new custom built computer connected wirelessly to my Router. My router is an SMCD3GN. So it is a Router/Modem in one. I am currently using the Linksys AE3000 Wireless-N USB Adapter. I have had a past Wireless USB Adapter, & an internal Wireless network card. The USB quit working & in order for me to get it to work is I have to reinstall the drivers everytime I turn my computer back on. The internal wireless network card would randomly lose internet every 30mins - an hour. Being a gamer, this is very frustrating. So, right now I am using the Linksys USB, and I was just playing a game & talking to some friends on skype & I would lose internet for 2 seconds then it would automatically reconnect. So I am beginning to think that it might be my Router but I tried my USB on my laptop for like 10 mins (I disabled the internal wireless network adapter) & I went into cmd.exe and pinged google for about 10 mins, & it said "Request Timed Out." several times.

We have about 15-20 APs out in the field, and at random they seem to disassociate from the WLCs and re-associate within a few minutes. We have not looked into that entirely yet, but we are having an issue with a few. Sometimes, they will disassociate and after a few hours reassociate.

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.
I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

isp is Comcast. They have had 2 techs come out here to look at problem and found nothing. I'm on a wireless connection with router in the next room. Modem was replaced a week ago and still problem persists. Landlady says she has no problem (shes the one in the next room and is connected directly) but I think that because she doesn't notice (I play online games so its very noticeable). I have excellent signal from router. This is my report:
Windows IP Configuration
Host Name . . . . . . . . . . . . : *****
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown
IP Routing Enabled. . . . . . . . : No

We have a bunch of computers(70 aprox) connected to a domain. Since couple weeks ago very strange issues started occuring, internet and network access(path to network share is lost) would come up at random times and on different machines and would last for about 10-20 seconds it would re-connect again.All the computers are using private addresses.Most machines are windows 7, some are xp.Using Windows server 2003 as dc.Since the occurance is so random it's very hard to pin point the cause.

Since about 3 weeks ago my DSL has been getting totally random ping spikes, from under 40 to over 1500MS for minutes to hours on end. Nobody else is using my internet, I've verified this. There is nothing sucking up bandwidth on any connected device or computer, as far as I can tell through troubleshooting to the best of my ability. I tried switching to a Cisco X2000 modem/router combo and it did nothing, still totally random latency. Also, when I called AT&T about this, they didn't even know what ping was. They ran an upload/download speed test (which is still mostly consistent regardless of latency) and told me I was basically making the issue up.

We currently have around 150 2975 switches and have had problems with it them not handing out PoE power to the cisco phones and access points at random times. There is plenty of power left for the switch to use. We have at least 15 that will be running fine for about a week and then all of the devices that use PoE power will shut off and will not come back on until we reload the switch. If you console in there aren't any messages that pop up and if you look at the port it just shows on connected or will show IeeePD in the power inline. We have contacted Cisco TAC and they just RMA them.

I'm using a Cisco 2821 router to provide temporary Internet access for a private network of about 300 users for a conference at a hotel. The hotel has provided me a public IP address for the WAN side. On the LAN side I have a 10.x.x.x /8 subnet with the router providing DHCP and NATing (overload) across the WAN interface.
Users can pick up an IP address and access the web. Light web pages such as Google tend to load without issue, however if a user does something that takes more time, such as streaming a Youtube trailer or opening an RDP session, the connection will freeze.
It doesn't appear to be related to bandwidth availability. Pings return on average 10-15 ms. However, I will get a request time out about every 10th continual ping. Steaming video will load about 4-6 seconds worth of data, then will appear to freeze without dropping. Doing something like speedtest.net will send a large amount of data then will hang, without ever ending the conversation.
This doesn't happen when I plug a laptop directly into the hotel public Internet line. They also don't have issues with their network similar to this.
I do not have any ACLs, etc. loaded. The router is basically wide open as far as I can tell. I don't see the router resources getting used much at all.

I have a Cisco 1921 to replace our current router which is constantly freezing. We have a couple inside servers, one is a web server and application server which needs to be RDP'd to by a couple of clients outside of our network. I cannot get this to work no matter what. I know it's not the server's setup as when I plug the network back into the old router, it works just fine.
All clients have access to the internet, and I can successfully ping/resolve hosts from both the router and a client computer connected. I cannot, however, rdp using neither our public IP, nor our hostname. The hostname does resolve to our ISP assigned IP, but the server cannot be contacted, leading me to belive this is a NAT issue.

I have been looking for a new router as my current one has packed in. I am mostly interested in a router with a fast and stable wifi and high throughput which can manage a high amount of maximum simultaneous connections. The linksys e4200 seems perfect and very well reviewed.I am currently on adsl, no cable in area, so i would need one to have an adsl modem. Is there a version with a modem? Or will i need to look around for another?
I am mainly interested in throuput and the reviews and comparison sites sugest that linksys seems perfect midway between max simultaneous connections and price. Any comparison website that has adsl routers. The information am looking for on that's between £60 and £160 with high amount of ram, high throuput for Maximum Simultaneous Connections, similar to link text

I'm running (C7200P-ADVENTERPRISEK9-M), Version 12.4(24)T4, RELEASE SOFTWARE (fc2) on a Cisco 7204VXR (NPE-G2). Currently, the router has about 200 VLANs configured on dot1q subinterfaces.
Now, the router hangs everytime we try to add a new Vlan.
Is there a well-known bug with the IOS version?

When I power on our ASA 5510 it just hangs on "Launching BootLoader...".
I've managed to get into ROMMON before it attempts to launch the bootloader and tried to restore an ASA image but it said disk0: failed to mount.I've copied the console output but am not sure if it is useful to diagnose the problem or not (and is quite long)

I have some issues with win 7 64 bit pro. I have 3 computers on a cat 5 wired home LAN using a DGL-4500 router and in yhe same homegroup. All are gigabit capable. 2 are regular PCs, one is an HTPC. All have the latest drivers.1) File transfers never exceed 12% of the network capacity.2) If I transfer from computer A to computer B's public folder, I can transfer 1GB in a few minutes. However, if I attempt to copy/paste a file from Computer B's public folder to computer A, computer A takes forever "discovering" the file, then gives some absurd transfer time, say 11 hours for the same file.3) If however I go to computer B and paste the same file into Computer A's public folder, the transfer takes only a few minutes.
4) If at any point during scenario #2 I right-click B's public folder from A during a transfer, I get the spinning circle forever which 90% of the time results in Explorer hanging and requiring the process to be killed/restarted.
