wireless wont work with sp2

[wrwss]

Inspiron 5150 with internal wireless. When updated to sp2 both the wireless and nic show limited or no connectivity. If I remove sp2 it will work correctly. I tried the windows hotfix for this problem, removed firewalls and a/v and searched here and the web to no avail. Does anybody have any suggestions ( and I dont want to hear get rid of sp2)

Did you try the Dell support forums? If this is a known issue for that machine they will know.

Tried dell support, no help. Tried microsoft, no help. I finally got the wireless to connect to the router but it will not display a web page. I am totally stumped! I think I need a re-format.

Did you post on the support forum as suggested  or what specifically did you do?

A reformat and reinstall may solve the problem if there are other non-hardware issues. Back up your data first if you need to.
