if you suspect ip issues,
then best option is to try to NOT use dhcp, you can then enter a specific IP address, subnet mask, and gateway.
(if you do this, you will eliminate any possible IP issues, and will know its just a wifi issue or not0
if you dont know these values, and have a windows machine connected on the wireless network, then you can type
to display suitable values for your iLiad,
(note: make sure the IP address you use for your iliad is not in use)
hmm not got my iliad here, not sure if iliad wifi dialog supports non-dhcp.
btw, if you use the wireless.debug script i supplied
in the text file it generates, it will say
""looking for dhcp"
"looking for dhcp - failed "
if the dhcp / ip address failed
as before other things to try, are to try without any encryption as a test.
also someone else here has said that Wireless N enabled routers wont work with iLiad, i cant confirm this though - as i dont have one
