Netgear DGN2000

Sorry if this appears twice (thought I gust posted, but cant find it now)

I have been nusing a Netgear 834 modem/router in replace of the sky supplied sagam unit for several months (no prolems obtaining adsl username / password)

I have just upgraded to the DGN2000 router (n standard wireless) and am having problems - the line sync ligh goes green, and I can see 9k / 10kbps connections established, but the 'i' light goes red - CHAP authentication failed (?)

I have checked and double checked that i am using the same username/password, etc

any help much appreciated

Problem sorted - not sure how, just re-entered evertying, so must have made a config error 1st, 2nd, and 3rd times around !
