Wireless network card keeps disconnecting

Go to your Internet Connection Properties & to your Internet Protocol (TCP/IP).  Go to the Properties of the TCP/IP & to the General Tab.  At the bottom, click on Use the Following DNS addresses.  Here, type in the numbers for the Primary & Alternate DNS servers.  You can find these numbers at the configuration setup for your particular router.  For example:

Primary DNS server:     24 . 168 . 190 . 48

Alternate DNS server:    24 . 168 . 190 . 49

These are just examples & your numbers may be completely different.  This procedure solved my intermittent loss of wireless connection.

si_si,

Try this. Enable wireless client ability to configure your router. I beleive that u can also limit that by IP address or Mac address of your notebook so that only your wireless pc will have the ability to change settings on your router across a network(this won't afffect the ability to configure settings thru your other pc thats hardwire connected to your router). Login to your router settings web page, usually its 192.168.0.1 or something like that. Find the page that has the Reset button and save it to your favorites list.

Now whenever you start your wireless notebook, fire up your browser, goto the reset router button page (saving to your favorites list makes it easy to find it quickly) and reset tyour router. Once u reset your router, until you shutdown and restart the notebook again I can safely predict that chances are you won't lose your connection. Its what I've been doing for close to 3 weeks now and I haven't lost my connection yet.

I actually have a shortcut to internet explorer saved in my startup folder, and I set my home page to reset button page on the routers settings web page and this way whenever I start (or restart) my pc it automatically  takes care of everything. All I need to do is click ok to log into the router settings webpage and then another click on the reset button.

Hopefully it works for you too.

Hi.
I have a inspiron 4150 with a TM 1150 wireless card in it. I have a Belkin wireless basestation hooked to a switch on my LAN. I also have a problem with XP and the wireless network keeps disconnecting. Especially if I try to copy a large file (>40Mb) over the network. I have tried upgrading drivers and almost any thinkable setting that could affect such behaviour. The most strange part is that I have a dualboot setup with Linux RH 8. When I use Linux (which I almost always do) I have never had any problem with such behaviour. My network setup is exactly the same in linux/windows. Same channel / IP etc. So this must be a Windows / driver problem i guess.

Try not letting Windows control the wireless connection, but use the Truemobile utility.

It may be too soon, but I think the suggestions from above have fixed my problem with disconnection on my Linksys dual-band PC adapter. I unchecked the "let windows configure the adapter" and the "enable 802.1x authentification ..." (the power saver was already "off" and the transmit was already at 100%). I have had a steady connection for about 10 minutes now - a record! I don't know which of the two things worked, and I'm not going to fool around to figure it out - I'm a happy camper.

There were numerous other fixes from other forums - adding new keys to the registry and disabling zero wireless in XP (when I did that I couldn't get the adapter to recognize the router), but none of these worked.

This is such a pervasive problem, obviously with Windows, I can't believe that there is not a common post to let everyone know.

One more update on the disconnecting wireless. When I booted this morning, the adapter wouldn't connect, even though the network was available. So I re-checked the "let windows configure the adapter" box, and I got connected - and it's steady. So for me, the disconnection problem was the "enable 802.1x authentication" which is still not checked.

Apparently for Linksys, when I installed the adapter for XP, it relies on windows for configuration, unlike the Microsoft adapters that are on my other PCs on the network.
