Wireless Constantly Disconnects

Somnus · 03 Sep 2009

When on Windows 7 (release 7100, 64 bit), the wireless internet disconnects after/during downloading a file, game downloads updates, or even when playing an online game. The internet still appears to be connected to my network however a message mentions "limited access". If I disconnect from the network, I am unable to reconnect to the network (error comes up).

This issue does not occur when using Ubuntu (dual boot) or on other computers connected to the internet (using Win XP/Vista). And does not occur when directly connected to the internet.

I also have noticed somewhat of an issue that may be relating to this problem. My network adapter is Belkin Wireless G Desktop Card F5D7000. However, Windows 7 recognizes the network card as "Dell TrueMobile 1300 WLAN Mini-PCI Card"

Thanks for any help~

I've got the same exact problem. I have a Rosewill RNX-N2X wireless adapter. My computer does the same thing - the wireless connection comes up with limited access and it won't connect again.

Along with this though, when this happens, my CPU starts getting eaten up to almost 90% usage by something. When I try to shut down, it just locks at the shutting down screen, and I have to hold in the button.

The connection works most of the time when just surfing the web, but when making my account for this site it decided to disconnect. I've tried changing the wireless security, channel, drivers, etc... When I try a wired connection, the connection stays fine under heavy load, so it must be something with wireless drivers or something..Please help!

Edit: Also, my router is a D-Link DIR-655, but I don't think it's the problem. A Windows 7 laptop does not have any problems with this using the same router.

Edit 2: Nevermind, wireless disconnects even when surfing web after about 3-4 minutes, but downloads stop it instantly.

You need to check the following is set up correct

Windows 7 contains both the familiar IPv4 stack and the new IPv6 stack; you do not need IPv6

at present disabling IPv6 in Windows 7 will help to speed up the connection on your broadband

service

In the “Local & Wireless Network Connection” you need to un-tick the following items

“Internet Protocol Version 6 (TCP/IPv6)”

“Link-Layer Topology Discovery Mapper I/O Driver”

“Link-Layer Topology Discovery Responder”

Click OK after un-ticking the above for the changes to apply

At the top of display the type of Lan or Wireless card will be displayed

Click Configure – Click Advanced Tab

Click Connection Type - Change to “Auto- Negotiation”

Click Power Management Tab

Un-Tick if selected "Allow Computer to turn this device off to save power”

Other setting to check

Right click on the wireless Icon in the task bar – Click “Open the Network and Sharing Center”

Click “Change Adapter Setting” left side of page

Right click on “Wireless Network Connection” – Click Status – Click “Wireless Properties

Button”

Tick “Connect Automatically when this network is in range

Tick “ Connect even if the network is not broadcasting it name (SSID)

Alright, thanks for the help, but my problem is still occurring

I noticed that I don't have the Connection Type option under advanced to check "Auto -Negotiation". I do have

Adhoc support 802.11n - which is Disabled
Country Region (2.4GHz) -#0 (1-11)
Country Region (5GHz) - #7 (36 - 165)
IEEE802.11h - Disabled
Multimedia/Gaming Environment - Enabled
Radio On/Off - Enabled

Also, from what I've read in other posts, I have disabled the IP Helper service and Windows Media Player Network Service. I also noticed that Internet Connection Sharing is disabled.

Any other suggestions?

The reason your Belkin Wireless G Desktop Card F5D7000 isn't working is because it's not a currently support adaptor for Windows 7. You can see it on the chart here as unsupported for Windows 7, scroll down near the bottom of the page.> http://www.microsoft.com/windows/com...Card%20F5D7000

The things that Ambra4 suggested made it so I could constantly have a connection, but I still lose connection and CPU usage shoots up when I try downloading or anything that requires a lot. Maybe I have had two different problems..?

Nope they are one in the same. Those registry adjustments are only attempting to make up for using improper non Windows 7 approved routers, firmware or drivers, plain and simple.

Ambra's statements are only a work around for the real problem, and the part about IPv6 slowing down broadband connections is utterly rediculous. I have no such problems with my broadband speed. If it were true then it would be true in every instance.

I also never needed to do any of those work arounds just to get my network up and running. If the problem was with the Op system itself than everyone would be having this problem and that certainly is not the case.

Disabling IPv6 has to be the lamest of all work arounds. Sorry folks but I have made up my mind on this. If you are having network problems it's either your network drivers, network adaptor or your router, that is all there is to it.

His entire post is attempting to make up for non Windows 7 approved hardware.
I have been there and done that already and have zero doubts about this fact. In the end it's best to purchase new Windows 7 hardware or if you are lucky a firmware or driver update will fix the problem. I have helped quite a few fix this problem with new firmware and drivers.

Aren't you contradicting yourself by saying this? The things that Ambra4 suggested made it so I could constantly have a connection, but I still lose connection and CPU usage shoots up when I try downloading or anything that requires a lot.

You first say you have a constant connection then in the same sentence you say you are losing the connection and CPU usage goes way up? I have seen the exact same complaint about a million times. It's a hardware problem period.

I've been here helping since Jan. and I can tell you that none of the problems are with the Op system itself. If you are using non approved Windows 7 hardware, or drivers then the results you have now are what you can expect.

Sorry for posting here, I've been very frustrated with this problem and I found a thread started by someone with the same problem so I blindly posted to try and find a fix, I guess this is the wrong place to find it

I hope you're right about it being hardware/driver problems cheve65 I've installed the drivers for my linksys wusb100 and it's has been running correctly for about an hour and a half now.

The Linksys page show that your wusb100 version 2 adaptor is indeed supported for Windows 7 so no doubt that will fix your problem for good. :)

People often mistakingly blame the Operating system for these types of problems, I have found out beyond any shadow of a doubt that all networking problems with Windows 7 are related to outdated or unsupported hardware. Pursuing any other avenue of repair is a waste of time and can also damage your Op system.

I'm glad you followed my lead on this instead of playing around with the registry settings.
