DSL Light flashing on BT Router

[ianp 0]

Even as I was writing this, the dsl light on my BT Voyager 205 Router is flashing, causing the connection to drop. Have tried getting help but no luck so far. Have XP on my computer and have done everything to resolve the problem.

SYMPTOMS:

DSL light flashes, line drops.

Very slow in loading/displaying web pages and won't up/download files.

Have tried to download the BT Broadband Help software but again the line keeps dropping.

When I start to download, the KBs is high (around 200) then rapidly drops to 10KBs or less. What should take less than 3 minutes to download on broadband is now impossible due to line dropout.

CAN ANYONE HELP?

Many Thanks
