Re: Lose Connection Frequently

The title says solved but I don't see a solution?

I am having the same issue at two different homes.  I randomly have the SB8200 drop to near zero on speed the ligghts show connected.  I am using this with Google WiFI.

 

Here are recent logs that look the same.  If I power off the modem things go back to normla and them randomly it drops or disconnects completely and all of the Wifi's start resetting.

 

I also turned on the Link Aggregation Configuration and I locked the DNS on Google Wifi to xfinity's 75.75.75.75
