hi guys,
ive given my black modem to father in law to replace his single port non wireless router.
ive flashed the firmware back to sagems using this procedure: Sagem router has been cracked - take 2

i can access the router stats page & at the top right it says adsl connected, internet no connection. the light for insternet connection is solid red.
i have a username & password from his ISP but the router says the name is too long??
i want to know if anyone has managed to get this working on a different network & where to start from (factry settings all the way to allowing wireless connections).
any help or tips will be much appreciated
