Dell Laptops And Wireless Network Access
We have a number of different types of Dell laptops [Lattitude, E5500, D520, D531,...] and they work well apart from this one little that appears to have started to happen only recently [perhaps due to a Windows update?]
The problem occurs in one of two forms:
1. When logging to the domain as a wireless client they will logon OK and get their desktop. After a short while the desktop and start menu items [redirected using Group Policy] disappear.
2. The laptop does not allow logon until it has been powered up for some time [maybe half an hour]
Upon investigation I found that the Windows utility to manage wireless network access was handing over to the Dell/Intel utility [Intel ProSet and DW WLANCard utilities]
I have tried using only the Windows utility to log clients on and only the Dell/Intel utility. Neither approach works. I have updated all drivers and applied all the appropriate Windows updates.
I am now at a loss as to what to try next.
Any suggestions would be most welcome. Thanks.
