Several users have reported a problem in which Windows 7 RC1 systems either cannot connect to wireless networks or display the message low connectivity or no connection when attempted to the network. In some cases, using Windows 7’s built-in “fix” routine can resolve the issue, albeit temporarily.
Fix
Updating to the latest set of Broadcom wireless drivers, for systems that use Broadcom chipsets, resolves this issue for most users. In particular, users have had success with driver version 5.10.79.7, available here.
You may also want to run Windows Update to check for the latest drivers for wireless hardware from other manufacturers.

I can’t thank you enough for posting this comment. After searching on google why my wireless was being so awful under Win7 RC I came accross this website. A quick download and my wireless is now absolutely fantastic – as quick as ethernet with pings to the router averaging 1ms. (Contrary to the previous 100ms+ and constant timeouts)
Microsoft Update currently has version 4.x of the driver.
This version (5.x) will hopefully be on Microsoft Update soon. Until then this download is a brilliant fix to the problem.
Thanks again!
oh. my. god!
thank u so!! so… much!! i’ve been searching for hours for this fix

I still have the same problem, I had the dirver mentioned above (ver 5.10.79.7) My system is an Alienware m17x laptop quad-core 8 gig ram. I download the latest driver version from dell (recommended for win 7) (ver 5.30.21.0) but still no joy, this is getting really annoying, was working perfevtly before I upgraded from vista to win 7 (enterprise edition). Having search the net some say to reset the router I did, but didn’t see why as all my other machines can see it no problem. Some others say to disable homegroup, didn’t work either, if any one can shed light on this it would be great as I actually like using win 7. Lastly haven’t found it yet but have microsoft themselves admitted to this problem.
