I have a problem with a wifi access point. I have users intermittently being able to connect, then next time they come into the office they get the limited or no connectivity error. I feel like I have tried everything with this. I dont believe its a DHCP issue, as wired works ok. I will write a list of things I have tried already to avoid people suggesting it, and will also write a list of what else I intend to try.
Swapping from B/G to A wifi network
Turning off other wifi equipment and removing interferance
Removing 3rd party wifi software such as intel proset wireless
Trying a different wifi point
Rebooted access point (this seems to fix things until they try reconnect again)
Upgrading firmware and drivers on effected laptops
To try -
Turn off 2nd LAN adapter on DHCP server and try running it on one.
Change to static IP when getting the error to see if it starts working
Install XP SP2 fix which addresses this issue
Turn off the Sophos software firewall on the effected PC's
I come here as somebody may know another way or have seen this before, so please I am very desperate to get this fixed as its being going on a while now, any suggestions MUCH appreciated!!!
