We have switched our external laptops users over to Verizon WIFI hotspot cards, which require the use of the laptops internal wireless connection. The issue we are running into is that the wireless on some laptops will occasionally not come back on from hibernation or standby. The WIFI just will not work at all. When we try and open the Dell wireless utility nothing happens.
The only way of getting the wireless back on is to shut the laptop down and pull the battery out for 1-2 minutes.
Occasionally this will not work either, and I will have to try and disable and re-enable the built in wireless card in the device manager.
And if all else fails I have to log into the laptop as an administrator and do the same steps.
I have unchecked the box in Power Management to turn off the device to save battery. I have updated the drivers.
Any other suggestions?
This is on Window XP laptops, the laptops are various Dell models ranging from D630- to E6420.
