Unplug the power cable from the back of the DSL modem for about 30 seconds and then replug it---it's simple, but a quick power cycle of the modem will briefly reset the modem and will often restore your connection.

2
Check your router connection. If your router has a blinking status light, then you wont receive the DSL signal---try power cycling your router.

Check all of the filters on the phone line your DSL service is using. Make sure each filter is securely inserted into a phone jack---every device plugged into the shared line should have a filter on it.

Contact your Internet service provider (ISP) for information about any service outages in your area. If there aren't any outages and the problem is recurring, take note of the time of each outage. It could be a persistent line problem or interference triggered by a streetlight on a timer.

Remove possible interference from the area near the modem. Excessive splitters, cordless phones, lamps and old power blocks can weaken your DSL signal.

Try surfing without a firewall for bit. If you're able to connect to the Internet with your firewall disabled, adjust your firewall settings to allow the DSL connection.
