its just his pc. been happening in two different houses, with two different connections and routers.
i think its all set to automatic. i'll double check.
andd. i'll do that ip config thing in a minute and see what happens

i probably should have mentioned. its the connection in our house that hes trying to connect to. the rest of us can and could in our last house. but hes not been able to connect to either or his one at home
