Issue with Modem CM1000 and router working together

Varian66 · ‎2021-02-02

Having issue with Modem CM1000, working with Router tplink AAC4000. Initially when I setup the router it was working for about a day. Then it started to cause the modem to basically shut off > no lights on Power, uplink, download , internet. The light for the network showed orange.

If I turn off the router > the modem functions again.

Soon as turn on the router > same thing happens

Correction on the Router Model > Archer A20 (US)

FURRYe38 · ‎2021-02-02

Try a NG router. TP-Link isn't recommended.

Be sure your using good quality LAN cable. CAT6 is recommended.

Varian66 · ‎2021-02-02

Getting a new Router is not the issue the Archer A20 is new. After researching the errors that the modem was reporting, going to get my ISP to investigate my lines into the house for noise.

Thank you for the response on the issue.

Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
