Troubleshooting Steps for DSL
Power cycling the DSL modem causes it to re-establish your DSL connection and network connection to your PC.
- Unplug modem from wall socket to reset during power cycling.
- Turn the DSL modem off by locating and flipping the switch in the back of the DSL modem and wait for 10 seconds.
- Flip the switch back on and wait for another 10 seconds.
- Restart your computer.
It may seem unnecessary to reboot your computer, but a lot of Internet problems are solved by power cycling and rebooting. This is true especially if your computer has worked fine in the past and only just begun to show problems.
If possible, try and remove any network devices (hubs, routers, wireless routers) and plug your PC into the DSL modem. This will eliminate the possibility that other equipment is contributing to the problem you are experiencing.
Check the power indicator LED light and make sure that it is not blinking. If it is blinking or unlit, try doing the following:
- Make sure that the power cable is firmly plugged into the DSL modem and also make sure that it is plugged securely into the wall socket.
- If the light is still off, try plugging into a different outlet/power strip to make sure that power is going to the unit.
The "DSL Link" (some modems have ADSL or PPP lights) status light should always be on and not blinking. This light will blink when the modem is trying to connect to your DSL service. The DSL modem should be able to establish a link in about 30 seconds (may take up to two minutes depending on your location). If the link light continues to blink, try the following:
- With the exception of your DSL modem, make sure that all devices plugged into the phone line such as telephones, fax machines, satellite receivers, or anything else that uses your phone lines have a DSL line filter or has been filtered at the NID. Your DSL modem should be the only unfiltered device on the phone line.
- Check to make sure that the phone line coming from the wall/DSL filter to DSL modem is securely plugged in on both sides. Also, make sure that if you have two ports on your DSL filter that the modem is plugged into the side that says, "Modem." (Usually, you can check for this by flipping the filter over and looking at the back. The two ports are labeled Phone and Modem.)
- Try plugging your DSL modem into another phone jack in your house. There might be internal wiring problems with a particular jack, which could be simple to check.
- Try plugging a telephone into the line your DSL modem is plugged into. Make sure there are no cracking or popping noises on the line. Also, your phone may or may not have a continual buzz while plugged in. This could be due to the DSL service running over an unfiltered line.
The LAN light should be a solid light or blinking randomly. The LAN light may or may not blink when you are sending or receiving information over the Internet. If the link light is not lit, try doing the following:
- Make sure the network/ethernet cable from your computer to the DSL model is plugged securely into the back of the modem and PC. Try unplugging the cable from both the DSL modem and PC and then plugging them back in to make sure the connections are secure.
- If there are any devices that are in-between your PC and DSL modem, try bypassing the device and connect directly into the DSL modem to see if the LAN link light comes on.
- If at all possible, try replacing the network/ethernet cable with another one to see if the cable itself is bad.
- If you have tried all the troubleshooting above and the LAN link light still does not come on, please call Copper Valley Internet's 24 hour helpdesk at 834-4357.
If you are running a third party firewall program on your computer (Norton Internet Security, Zone Alarm, etc.), it may be causing your computer to not access the Internet correctly. Try disabling the firewall and see if you are able to connect to the Internet.
