Reminds me of the cable internet I had in college. Every night it would drop for several minutes at a time. My homework included cisco labs using equipment we had to reserve remotely so loosing my SSH connections was maddening.
Numerous phone calls and technician visits. At some point was logging into the cable modem to measure the signal strength. Eventually a tech moved my coax connection at the drop? Problem went away, they said another tech would come back out and check on it.
One week later outages again. Lucky for me they offered one month money back guarantee. I returned that modem on the very last day to the dismay of the receptionist.
