Arris SBG6580-2 Router briefly but frequently drops internet connection, wifi signal stays strong throughout
I recently set up a new Arris SBG6580-2 router/modem combo. Probably once every 10-15 minutes it will drop the internet connection for 5-10 seconds and then reconnect. The wifi signal stays strong even while the internet connection has dropped out.
I have tested my devices on other wifi networks and this only happens when connected to my router.
My router's event log shows these two errors repeatedly occurring every few days:
| Tue May 30 01:10:05 2017 | Critical (3) | Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=bc:64:4b:9a:da:7d;CMTS-MAC=a4:4c:11:8a:dc:79;CM-QOS=1.1;CM-VER=3.0; |
| Mon May 29 09:14:04 2017 | Error (4) | DHCP RENEW WARNING - Field invalid in response v4 option;CM-MAC=bc:64:4b:9a:da:7d;CMTS-MAC=a4:4c:11:8a:dc:79;CM-QOS=1.1;CM-VER=3.0; |
I have tried several different channels. My current shows "acceptable" interference levels.
My security is set to WPA2-PSK (AES).
I have disabled WPS.
Thanks for your help.

I've looked at your modem logs and am seeing where most of the errors are where the wifi channel was changing quite often, due to interference. The few time-out errors you see are normally signal related. Does your modem's coaxial cable connect directly to the cable outlet or is there a splitter on the line?
