Try using the test socket nd see if that helps
the connection time is only 1 hr is that due to move to test socket or router dropping conenction? your connection speed has reduced as your noise margin is now at normal 6db whereas before it was 4.8db
with your current attenuation the exoected speed is about 1.7/2mb enter your attenuation here
I obviously misread time so it is bthe result of change to test socket.
if you have overhead cables do they go though any tree branches that you can see which could cause problems duing windy conditions
