I have a couple of wireless routers set up as ap's with dhcp turned off.
Set up a Toshiba 8.1 system the other day and it just won't take a dhcp address from the main router.
It's as if it thinks the AP is the main gateway.
It autoconfigures with a 169 address.
I thinking it's another frigging M$ feature they thought was a good idea at the time.
I have another 8.1 system that works fine and my 7 systems have no issues.
It just seems to want to use another router/ap as a default gateway.
