Wireless Keeps Shutting Off And On Randomly?
Mar 22, 2011
I tried setting up the wireless at my mom's house, and she has the following hardware:Motorola SB4220 Surfboard ModemNetgear RangeMax WPN824 RouterAll computers run Windows, XP or VistaAlso, when I go to Control Panel -> Network Connections, under "Local Area Connection" it says "Realtek RTL8139 Family PCI Fast Ethernet NIC". I guess that's a driver, but I don't know what that means.The wireless works, but it turns off and on randomly every couple of seconds, so anyone using it has to keep refreshing pages until it catches a signal.Here's something I think might show where the cause is: when I go to Control Panel -> Network Connections, it usually shows "LAN or High Speed Internet", but sometimes it also shows "Internet Gateway", and the following:

So I have this Netgear N900 (WNDR4500) wireless router. I have one PC connected via ethernet cable to the router and 4 wireless devices connected wirelessly. As long as the ethernet-connected PC is turned on, the other wireless connections work fine, but as soon as I shut down that PC, the internet connection is lost (although I can still connect to the router via the wireless laptops - router login page - so I know the router's wifi part is working). Why would my PC need to be on? Does the PC handle any of the internet connection for the router?
I hope I don't need to keep my PC running 24/7 so that the other devices can access the internet!

I am wondering if anyone has seen this before. We have about 50 AIR-LAP1242AG-E-K9 access points connected to a WLC5508 running 7.4.100.0. These were all being used as autonomous APs previously and were converted when the controller was installed. About 12 of these have a lovely feature where their radio interface goes down at random. The radio is still in enable mode but the opertational status is DOWN. It seems to happen particularly when there has been a power outage and the AP rejoins the controller. All of the other 1242s are fine and never sees this problem. The APs are all on power injectors.
Once the radio is down, the only way I can get the to come back online is by doing the following:
1. Set the radio admin status to "disable" and apply
2. Turn off CDP
3. Reboot the AP Wait until the AP is back online and registered on the controller
4. Enable the radio admin status and CDP.
If I do not remove the CDP setting I cannot bring the radio back to "UP". I know we had previous issues with autonomous 1242 APs that did not like CDP being enabled. Have I perhaps got a bunch that are like that? Despite these having operated as autonomous APs they are AIR-LAP1242 from the factory.

Can a computer on our network with no admin privelages cause other computers to shutdown? We have 15 machines that are having force shut downs happening but they are clear of viruses malwares, we have ran multiple scans and nothing but could another computer somewhere on the network tell them to force shutdown closing everything?

I accidentally ran a program that's invisible and my friend said in processes under task manager, right click one of the Javaw's and hit End process tree. I did it and restarted my PC. Then, ever since, servers for games have been acting up. For 3 minutes at the most, it goes fine, then disconnects everyone and lets them back on. Its for Minecraft, a java game. Its not the software. I've tried different softwares for the server.

I have several remotes sites connected to "home" with Cisco 891 routers at each remote site."Home" actually consites of two different data center sites, each with a Cisco 3845 router terminating the IPSec tunnels there. One home site provides VOIP phone service, the 2nd home site provides PC Data.Each 891 router has two IPSec over GRE tunnels configured, one tunnel goes to the VOIP home site's 3845 router, the 2nd tunnel goes to the DATA home site's 3945 router.All of my pre-existing 891 routers are still running IOS 12.4(22)YB5, and are working fine.My newest 891 router, purchased recently for a new remote site, shipped with IOS ver 15.0(1)M4, and when I have both tunnels configured similarly to the others, both tunnels come up and everything seems to work fine, but if I disable the VOIP tunnel with the "shutdown" command on the tunnel interface for VOIP, then the data tunnel will not come up at all, with full verbose crypto logging turned on, I never even see an attempt to bring the data tunnel up, and when I issue a "no shut" on the VOIP tunnel, both tunnels come right up. This behavior is not seen on the original 891 routers still running 12.4. I can shutdown the VOIP tunnel and the DATA tunnel will come up, stay up just fine.I really do not need the VOIP tunnel at this new remote site for the immediate future, but would like to keep the configs in place for the future, and also to keep all my 891s configured identically (different ip numbers of course) for consistancy's sake and easy of management.Do I need to install 12.4 on this 891? I'd rather keep the IOS on it that it shipped with.

I cannot shut down my laptop normally after the problem occurs. The swirling circle during shutdown freezes and I have to hold down the power button to close my laptop. He has a very similar laptop to mine, as well.

JMicron PCI Express Gigabit Ethernet Adapter (My old adapter that broke down after it caused an issue two times where it prevented my laptop from starting, So basically, my network adapters are shutting down after a random period of any intensive work on part of the computer, this includes Photoshop and most games. What happens is the network adapter shuts down. It takes a minute or two for the tab on the bottom right to register that the internet is actually down. Both wired and wireless adapters crash (I'm currently using a USB to Ethernet adapter as well, same problem existed before too) and I'm unable to restart the adapters in device manager. In rare cases, my wireless adapter survives but it usually crashes later on. Sometimes in device manager, the details for the my adapters have Code 10: The device cannot start error.

During a firmware update, the router shutdown rebooted, stayed on for about 1 minute and then powered off and never rebooted. 750DB, F9K1103v1. What do I do next?
I was having intermittent internet issues. I was advised by my ISP to update the firmware. I tried via web browser but when I tried clicking on the firmware update link I would lose the page or the page wouldn't load.
I then tried running the cd and installed the bellkin software and got everything working - it asked me to update the firmware to which I readily agreed considering the request from my ISP. Then during the firmware update, my problem took place.
Retried multiple times to restart the router as well as resetting the router.

We have a 2960 switch which is connected to the core via a VLAN trunk. We have disabled broadcast port suppression but, the 2960 is shutting is shutting 2 ports down on the network and this looks like excessive braodcast. How and why would the switch start dropping traffic when the default is don't do anything? It had to be rebooted to get the port active again

My wireless adapter keeps turning off randomly on my HP G60 120EM.
It will have my connection strength icon on the icon tray and then just randomly display an adapter with a red cross through it.I have made sure that the adapter is not set to turn off on power save but still the problem persists.I thought it could be the adapter being loose inside the laptop but if i give the laptop a small shake it doesn't disconnect and I opened up the laptop and everything seems fine.This is where it gets a bit strange. If I close the laptop lid then open it again, the wireless is fine, but will drop off again about a minute later.

I am currently picking up off a friends internet connection. Every day it seems to randomly kick off. I have tried a few troubleshoot fixes and none have worked. This has only happened with my friends connection before my wireless worked just fine. Is there a way to fix it from crashing?

My wireless internet will randomly shut off, roughly every other day. It will shut up and say that my wireless router needs to be reset, but all other wireless devices continue to work throughout the house. I could run any amount of diagnostic but it will not fix. The only time it fixes it when it says "repair as administrator" as one of the options in diagnostic test which does not always appear. I went to school yesterday, and my laptop would not connect to the wireless network there at all, but everyone else around me connected fine.

I just bought a linksys AE1000 usb wireless adapter for my desk top computer because there are no phone lines in the room with the computer for me to connect the dsl modem. In the room with the dsl modem there is the Linksys E3000 wirless router. My desktop will randomly lose connection with the router yet other devices that use wifi in the house work fine (ex: ipod touch, android phone, and xbox 360.) i have went through and reset all devices and gave the desk top priority in the network but it hasnt worked. The desktop uses XP.

My internet works fine but after a random period of time, usually 20-30 minutes the internet stops responding. I have ran a diagnostics test using the Intel PROset/wireless tools program and it states on the ping test that there is no response from the default gateway and the DHCP server.

My wireless connection randomly drops, or has no Internet connection, or says it has connection and Internet but no web pages load. Usually, what happens is it says I have no Internet connection. I have to disconnect and reconnect to get the Internet back. My ethernet connected computer never loses connection.
I am running Windows 7 with a Realtek wireless card. I have updated the driver to the latest. The wireless router is a D-Link 615 e1 using DD-WRT. The router is hooked up to a Brighthouse Arris TM402G/110 modem for internet access (note: this is my second modem. I had the same problem with another modem. Unfortunately, I don't remember the name.)
When the router is connected to a U-Verse 2Wire 3800HGV modem/wireless router (with the wireless turned off) I have no Internet disconnections. Everything else is the same (I just move the Ethernet cable between the two modems). Of course, one is just a modem and the other is a NAT router/modem.
I noticed that the wireless connection has a weaker signal when connected to the Brighthouse modem then when connected to the U-Verse modem. I therefore tried to up the TX signal strength on the router. This improved the situation (and the signal strength) but I still get disconnects. I also tried setting the MSS to 1492.

I have a 2Wire 2701HG-B modem/router provided to me by AT&T for my DSL service. I have one issue and a seperate question sort of related to it.The issue I'm having is that whenever a laptop gets online with wireless internet the modem will randomly reset connection.Some times it will do it every 30 seconds, some times it will be once an hour or even more.It works perfectly fine on any laptop when plugged in with Ethernet cable but only with wireless it will glitch out. It does this whether it is the only computer online on the network, and also when there are a few others online so it's just the simple fact of the wireless resetting it somehow.I've done lots of google searching and some people say changing the line pair settings fixed it for them. Some say changing from b/g mode to just g mode fixed it. I've tried every thing that I've come across and nothing has worked so far. Apparently this is a very common problem for this model I just can not find the right solution that has worked for other people, to work for me as well.
if I were to want to make this modem/router just a modem and hook up my own router for N wireless would this be possible? I know I've read ways about putting combos in DMZ mode or something but I don't really know what I'm looking for because everything is worded different in this modem's settings.Can any one provide any insight as to if this is possible, and if it's even worth it to do so? Mainly worried about the first thing I mentioned though, this is just a side note.

I have a DIR-625 router that has been acting odd lately. Several times a day at random my devices (laptop, android phones, PS3) will lose internet connectivity from my wireless network. They say they are still connected to the network but I am unable to access the internet or even the router config page. Everything works fine on Wired LAN computers. The only way I can fix it is by unplugging the router for a few seconds. I have had the router for over a year now without this problem. Seems like it may have started when we got our android phones.

I am currently using a 5508 Cisco WLC with software version 6.0.196.0. It has been running smoothly for the past 1.5 years, but have recently discovered that the WLC will randomly restarts itself. I know this because I have seen the disruptions in our wireless network, as well as seen the Up time counter reset itself. I have tried looking at the trap logs to see if there is any significant network traffic that may be causing this, but from what I can tell there is nothing out of the ordinary. The restarts happen randomly at random times. I have never seen a Cisco device behave this way, not a switch, a router or security appliance for that fact. What may be causing the WLC to just reboot itself?
