Correction on the Router Model &gt; Archer A20 (US)

FURRYe38 · Answer

Try a NG router. TP-Link isn't recommended.&nbsp;Be sure your using good quality LAN cable. CAT6 is recommended.&nbsp;&nbsp;

Varian66 · Answer

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.

FURRYe38 · Answer

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.&nbsp;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.&nbsp;Be sure your using good quality RG6 coax cable up to the modem.&nbsp;https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853
