Re: CBR40 connectivity issues every 1-3 days

So, I am basically just looking for a place to start with this one. For the past couple of weeks, my CBR40 router drops connectivity every 1-3 days. I am not 100% certain that it is the ISP, although that is certainly possible. When the connectivity drops, it often takes 60 seconds or more to bring up the router page, but the performance after that intial login time seems fine. Unfortunately, simply connecting to the router does not restore connectivity to the internet, and if I try to release the IP from the ISP, I cannot renew without doing a restart on my router. 100% of the time, when I perform a restart, it then begins working again with no apparrent issues. Currently on firmware V2.5.0.14_1.0.8. I have the following from the event log from this morning, prior to another connectivity issue. Unfortunately, I am not yet up to speed on what I am looking for, but any help is appreciated. I am more than willing to contact my ISP, but they are, quite honestly, a PITA, so I'm just doing some checking first.

a screen snip of the event logs and the cable connections help.
From the little bit you put, it indicates a line issue.
If there's any splitters, amplifiers, or signal attenuators in line, remove them.
inspect the line for kinks, damage, loose/old/bad/cheap connectors and replace them if there are.
prefereably, move the modem to right where the coax enters the home to prevent wiring inside the home being the issue.

Re: CBR40 connectivity issues every 1-3 days
There was an attenuator on the line, which has been there for years, but I had never noticed. Likely from when the cable company installed their own modem, prior to me purchasing my own Modem/Router. (This Orbi router is my second personally purchased modem/router since I have been in this house)
I can't explain why it did not cause any issues for the first year or so of use, but since removing it, I have only had one blip, during a thunderstorm, so likely not related. I'm keeping my fingers crossed, since it has only been a week, but hopefully that was it...thanks!
