Over the past few days, the ADSL connection has gone down a lot. Typically, the router will attempt to re-establish it; it often takes two or three attempts, and then the connection may only stay up for a few minutes before it goes down again. I contacted BT, who performed a line test and claimed that there's no problem.
It's intermittent; at the time of writing, the router/connection has been behaving; earlier this evening, it was up and down like a yo-yo.
Help!!!!!
