BT's favourite "fix" in this scenario is to disconnect the router for at least 15 minutes, to ensure that the exchange equipment and upstream side is forced to renegotiate when reconnecting.
I spent more time than I like trying to get a linksys to connect to a Zyxel router over the weekend, and noticed that the ADSL side was very flakey, and losing the connect way too often. That might be a factor.
Another possibility is your log on password for the router, there's confusion in BT over if it's lower case or upper case, and I've not got to the bottom of that yet.
Is the router configured for PPPOE, or defaulting to DHCP, that will for sure cause it to get very upset. If it's not set to PPPOE, then it will sulk and fail everything. |
