Hello all. Just a few days ago, my internet connection started dropping out every few minutes or so. It mostly just affects my ability to stream videos and play online video games, but it is still a problem I would really like fixed, or at least diagnosed, right away.
From reading about similar issues on other forums, it seems it could easily be something physically wrong with the cables in my apartment. It could even be due to the extreme cold we're currently experiencing.
I have an old Ubee DVM3203B modem, and no router. Went into the modem logs, and here is the relevant information:

Mostly, I need the collective expertise of these forums to determine if any of these parameters are abnormal?
Thank you!
