Wireless Internet Stops working in Build 7048

Reverence said:

For some reason my wireless internet connection goes to "Limited Activity" after just a few minutes of use on Build 7048. Once I've restarted it will work again.....for a few minutes, that is......then it goes back to "Limited Activity". I am currently using a Wireless Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Network Adapter.
I have tried to roll back driver the wireless adapter driver but I am getting same error.
I've since reverted back to build 7022 with works fine with my adapter. Is anyone else having this problem? If so....has anyone found a remedy?

I have installed both on dual boot.

does it report it's still attempting to resolve ip address ?

Well update its been working and I been downloading all day since I updated the drivers.

http://ftp.us.dell.com/network/R189137.exe

Those are the drivers I installed for everyone that wanna try to do this way.

Gonna put some more downloads for the night to see if problem solved completly.

memento so it works perfectly cause here it seems problem solved.

I think my issue is different to the OPs. For me connection is stable until I run my Bittorrent - then within approx 30-60 mins the connection will die and only a restart will fix it. I suspect bittorrent because when it happens I try to close the torrent client but it hangs. Win7 spins it's little blue wheel of aggravation constantly. Not even task manager can kill the bittorent process.

I have unistalled bittorrent and installed uTorrent instead to see if there is any difference.

I have build 7057 x86 and the same issue with my dell 1395 WLAN.
I will try to download the newest driver from dell website.
Thanks for the info.
