Some common steps to troubleshoot ADSL issues are: Reboot your ADSL modem/router. Your modem may have stopped working temporarily. Restart your modem and retry your connection after 2 minutes Log in to your router and check your username and password. Make sure you have entered the correct credentials provided by your ISP. If you are not sure, contact your ISP to verify them Check your telephone cabling and filters/splitters. Make sure the DSL port on the back of the router is plugged into the DSL wall jack with a straight-through RJ-11 cable23. If you use a splitter to connect your phone as well, make sure it is working properly and connected to the correct ports12. You may also need to use filters or splitters on other devices that share the same phone line, such as fax machines, alarm systems, or satellite receivers Perform an isolation test to check for faulty filters or telephone devices. Disconnect all devices from the phone line except for the router and see if the ADSL light becomes solid. If it does, reconnect each device one by one until you find the one that causes the problem. Replace or remove the faulty device or filter Check that there is no noise on your telephone line. Use a corded phone to listen for any static, crackling, or humming sounds on the line. If you hear any noise, report it to your phone company as it may affect your ADSL signal quality1. Check the status of the lights on the front panel of the router. The power light should be solid, the ADSL light should be solid or flashing, the corresponding LAN light should be on or flashing when a computer is plugged in, and if it is a wireless router, the wireless signal light should also be flashing by default2. If any of these lights are off or red, refer to the user manual of your router for troubleshooting tips. Check the controller status, operating mode, and transmission coverage (TC) mode. Use the show controllers vdsl 0 command to verify these parameters on your router. The controller status should be up, the operating mode should match the DSLAM type of your ISP, and the TC mode should be ATM for ADSL service3. If any of these parameters are incorrect, contact your ISP for assistance. Check the ATM interface status. Use the show interface atm 0 command to verify if the ATM interface is up and has a valid IP address assigned by your ISP3. If not, check if you have configured the correct permanent virtual circuit (PVC) values (VPI/VCI), upper layer transport (PPPoA, PPPoEoA, RFC1483 bridging, or RFC1483 routing), and authentication method (PAP or CHAP) according to your ISP’s settings23. You can also use debug commands such as debug atm events, debug ppp negotiation, and debug ppp authentication to troubleshoot further
