I have an iPad and use a Linksys WRT54G. The iPad worked great in WEP mode for several days, but lately has started forgetting - not the password, but the fact that it is a known network.
After it has been offline for awhile, I have to go into Preferences Networks and select my network from the list. Then it connects and gets DHCP address without asking for the password...
I don't want to fiddle with security yet. I live in a wide open suburb, so unless the neighbor kid starts hacking (not likely, I think he's stuck on level 6) my wifi should be relatively secure... 🙂
I have started with the recommendation to turn off multiples... My network was set for B/G so I'll set it for G and see if that helps...
Thanks!
