Internet connection drops randomly throughout the day
Over the last 6 weeks or so my internet has been dropping randomly for a few minutes but comes back after a few minutes. I've tried connecting directly to the modem using an ethernet cable and have the same problem. I also had an Xfinity tech come out to replace the line from the alley to my house. He ran some tests to confirm the issue isn't the wiring in my house before he replaced the line outside. I did everything the tech suggested and even replaced my old Arris modem from an SB6183 to SB8200.
I'm was seeing a lot of T3 timeouts on the old modem and pretty much the same thing on the new one. I do think the internet issues seem to coincide with high winds but not 100% certain. My wife and I both work from home so a stable internet connection is vital. My only other option for broadband here is Tmobile [Edited: "Language"].
Any advice is welcomed. TIA. I have another tech visit scheduled on Friday.
Here are the logs from my modem:
