Troubleshooting Your Tachus Modem

Tachus Community

If you’ve troubleshot and rebooted your wireless router, but you’re still not getting an Internet connection, here are some steps you can try with your Tachus modem.

Identify your Tachus modem

The Tachus modem says DZS on it and should be located where our technician placed it during installation.


Check your alarm light

Is there a red alarm light on the top of your Tachus modem? If there is, you’re having a problem with your connection, and you should callus. If not, the connection from the Tachus equipment works, and there’s likely a problem with either your router or your connection from your Tachus modem to your router.


Check your modem’s connection to your router

Is there an Ethernet cable going from the modem’s GE1 port to the router? Usually there is a specific port on a router for this cable labeled“Internet” or “WAN”. Replace that cable, and then try your connection again.


Connect your computer directly to your Tachus modem

Another way to make sure your connection issues are not in your Tachus modem is to try connecting your computer directly into the modem’s GE1 port with an Ethernet cable. If you still cannot connect to the Internet, we recommend you contact our tech support team.


Hopefully after reading the information above, as well as our article on common router issues, you can successfully solve your connection problems and get your Internet back up and running. If not, our tech support team is ready to help you. Check our blog for more information on how your modem works.
