Have a friends toshiba sat. laptop that finds wireless router but gets stuck displaying acquiring ip address.
matched most settings against my laptop all look the same.
Took it home and it finds my 2 wireless routers but same symptoms.
in safe mode with networking
check setting to aquire ip automatically , dhcp and auto configuration enabled.
disable, uninstall and update to latest driver. Atheros AR5005G 220.127.116.11.4 , 23/03/ 2006
try ping ip - no response.
tried several forums but running out of ideas other than drive reformat.
note this is a new setup, wasn't on wireless before.
