My network has a wireless access point. I have had endless hours of fun trying to get a Toshiba tablet to communicate with the AP using anything more sophisticated than 64 bit WEP. The card/driver combo would quietly refuse to communicate at the end of the association/authentication process -- leaving me with a seemingly successful connection but no access to the network. Endless combinations of settings on the AP and tablet produced nothing -- just an apparently successful connection that failed to get a DHCP address (or communicate with a staticly defined address). What made it most interesting is that none of this failure gets logged anywhere. My solution was to add a PCMCIA wireless card with more contemporary roots -- the extra hardware is not easy on the battery but provides the security requried. The wireless is using WPA with Radius (IAS), which works very nicely. I dont mind setting up guest accounts for visitors -- if they cannot get access due to weirdness there are spare wirelsss cards.
