Your router should have a page where it says how the connection is (connected disconnected etc), or at least I hope your router does.
The page to access the router is usually '192.168.1.1' , '192.168.0.1' or '192.168.2.1' . If not check your user manual for the address and log in details.

This most likely will help you determine what the error is.

DSL service is delivered simultaneously with regular telephone on the same telephone line as it uses a higher frequency band that is separated by filtering. So in other words even thought Broadband thru phone companies are seperate from Dial-up in that they use a different frequency and thus don't disrupt communication, they are still transmitted via phone lines and fiber optic cables...if the phone or cable provider which gives you internet access is working on the lines...your access will be disrupted. Nothing to do but wait it out and complain if it goes on too long.
Or the line got degraded too much and it can't handle your speed anymore. :/

My line can't handle 4mbps in a stable way. It'll disconnect multiple times a day (from 5mins inbetween up to 3 hours) and there's nothing you can do except to call and ask them to lower your line.
