had a similar problem yesterday... took my axim out to the mall stumbling ( 2 jewelry stores and a sporting goods store with waps and no wep.... free internet for stew eh?
) when i got home i couldn't connect and had to fix it.
check you ip.... if it starts 169, your card is not configured correctly ... uninstall and reinstall...the other option is to ck your router settings... assuming your router is 192.168.0.1, with dhcp and dns through the router, static address the axim to an available ip( i set my router up to address 192.168.0.100 through 192.168.0.112, enough ips for 7 computers (yeah, 7 in the house on 2 networks :D ), the axim, an hp4000 and a few spares for good measure. when you use static, you may have to include dns ips(get those from your router setup).
