Reboot your computer:
This may seem obvious, but when troubleshooting any computer issue you should always start by rebooting your computer. This is especially important if your computer has been working fine and then suddenly started to exhibit strange behaviour.
Reboot your ZyXEL 792H router:
Rebooting your router will force it to attempt to re-connect to the network. Once you have turned your router back on it will take a minute or two to come back on and re-establish its connection.
Check your router has power:
Your routers power, shown as ‘PWR/SYS’, light should be on and solid green.
Check to ensure the power adapter is securely plugged in to both the router and the wall socket.
If there is still no power try another wall socket that you know definatly works.
DSL Link LED Status:
“DSL LINK” ,shown as DSL, should be lit solid green. A solid light shows that the router is connected to the internet. The DSL Link light will flash when the router is trying to connect to your DSL
service. In most cases, it should take less than 30 seconds for your DSL router to connect and display a solid light. If the DSL link light continues to flash, try the following:
1. Check all of cabling including power, Ethernet, phone and splitters.
Make sure all of the phone devices (including Phones and Fax machines)have a splitter attached. If they do not then the devices will interfere with each other preventing the ADSL broadband Internet from functioning correctly.
2. The phone cable coming from your ZyXEL Router should plug directly into the wall outlet. Try bypassing any splitters or other devices as they can sometimes cause interference with your DSL signal. We suggest you remove and re-plug the phone cable into the ZyXEL Router and the wall
jack to ensure the cable is plugged in securely. The cable should ‘click’ when it is pushed into place
3. Try moving the ZyXEL Router along with it’s power supply and phone cable to a different telephone wall jack. There may be internal wiring issues causing problems with a specific wall jack or group of wall jacks at your location. Try plugging into the master telephone socket in your premises if you have access to it.
LAN link LED status:
The LAN lights should be lit solid or blinking rapidly, The lights should be either green or amber depending on your connection. The LAN link light will blink when your computer is sending or receiving data to or from the router. It will remain solid while no data is being passed. If the link light is not lit, try the following:
1. Make sure the ethernet cable connecting your ZyXEL Router with your computer is plugged into the LAN port on the back of the ZyXEL Router. We suggest you remove and re-plug the cable into the ZyXEL Router and your computer to ensure the cable is plugged in securely. The cable should
‘click’ when it is pushed into place
2. If there are any network devices between your computer and ZyXEL Router, such as a hub or other router, try bypassing them and run your computer directly into the ZyXEL Router. This will help you eliminate the possibility that one of these devices may be causing your problem.
3. The cable that connects your ZyXEL Router with your computer may be bad. Try a different cable if possible.
Check your firewall:
If you are running a third-party firewall program on your computer, such as Norton Internet Security or Zone Alarm, these may be interfering with your computer’s ability to access the Internet. Try disabling any software firewall’s that you have running.
