No Ranging Response received - T3 time-out (Connection drops multiple times a day)

Hello -- I've had connection dropouts for years, but they have increased recently (maybe due to speed upgrade they gave me?), so I wanted to find a fix once and for all.

 

I lose connection for 1-3 min several times a day. Any help would be much appreciated! 

 

Here is the current signal data and logs:
