Router keeps disconnecting?

my router (bt voyager 210 adsl) keeps disconnecting every couple of minutes, it has 4 lights that are

supposed to be on all the time, the DSL light and internet light are the two that keep going off. Any idea how to fix it

, I did a scan with spybot s%26d and avast and found nothing. thanks

Can't connect to the web, losing your connection or your access speed is way slower than advertised? If you are unhappy with their service, you MUST contact your Internet Service Provider (ISP), that's what they do!!!

Often, they aren't even AWARE of a problem, unless you tell them.

TIP: Just make sure your router settings, if you use one, are correct first.

Call the service provider first.

Replace the router if it's time to get wireless n.

Speeds will go from 25 with g, up to 100mbps with n
sounds like a problem with your DSL. Make sure everything is hooked up right, then unhook everything and go with cable.
