I manage a 150-AP wireless network running the 4.0.219 code with WLC 4400 controllers and 1242 AP's . We have a bunch of Dell laptops with Dell branded wireless cards (broadcom chipsets) that will suddenly stop working on our wireless network but will work at hotels, the users home, etc. Currently we give the users a Netgear PC Card and they work fine, but I would like to figure out if there is some issue with these cards.
Does anyone else have any similar issues???
