Try going into Device Manager, expand the settings for Network Adapter, right click your wireless adaper and select Properties, then click on the Driver tab and use the Roll back driver button to back to the older drivers.

It looks like a new driver for the Intel cards was posted today:

http://support.dell.com/support/downloads/download.aspx?c=us&cs=19&l=en&s=dhs&releaseid=R130002&SystemID=INS_PNT_PM_600M&os=WW1&osl=en&deviceid=8274&devlib=0&typecnt=2&vercnt=6&formatcnt=1&libid=5&fileid=173255

If this newer driver doesn't fix the problem, click on the link on that page for "other versions".

I have the same problem. I tried to roll back the driver but the R127811 had me uninstal my old driver when it tried to install. Where can download my old driver? I don't know what it was called.

Thank you
