i know how to fix the error, go to your connection settings, your and scan, put in wep if required and do everything automatic, but when it comes up to your DNS go to manual, for primary DNS type in 4 .2 .2 .2 and for secondary DNS type 4. 2. 2 .1
This worked for myself and hope it works for you all too share the knowlege and help people get back on line
FYI if it does not work switch the primary and secondary DNS around there have been reports of 4221 working for the primary and 4222 as the secondary.
as it says in the test connection, test connection speed is an estimat, i am not sure but i dont think it will have any negaive affect on your gameing, try to play an online game and let us know how it goes MOH worked for me.
