Long story short.
At end of last year (2020), we had a month where we basically had no internet service. Got a refund but little help from the provider except that our flag was interfering with the line of sight we needed. (Visionary - www.vcn.com) - Relay station. (reported high speed was 10MB down/ 2-4 MB up) -- we were getting much less.
Used the outages software agent and then hardware agent to try to catalog for ourselves the outages.
Fast forward to June 2021 -- got hooked to a different tower. Their speed tests showed 30MB down/5 MB up. Okay. Hardware agent showed it back online. Then, nothing until a few days ago when the hardware agent notified that the connection was back online. (though we'd had many problems connecting).
The outages people took a look and said we were getting almost constant disconnects. pointed to various parts of the connections. hooked the agent directly to the router -- that seemed okay for a little while and then started again.
It was worse this morning -- but it rained last night? I'm beginning to suspect the connection into the house. (could it be affected by humidity). I know they didn't lay a new one for the new Visionary connection (they did a splice from the new cable to the old) -- and wonder if they did when they first put in the Visionary connection or just piggybacked on the DSL connection that was here. (no idea what the previous owners had). I think we got DSL in about 2003 when we first moved in. Very dissatisfying. I'd have to see when we got the Visionary (pre-owned business - Skywerx) but it's probably been close to 15 years.
Oh, I also rebooted their connection this morning -- again, things seemed to get better after that. Before had had trouble connecting for speed tests.
We're in a very small, very rural community (Pagosa Springs CO). Few of our neighbors are tech savvy. OTOH our household has a gazillion things hooked up to our connection. Mostly retired two tech people in large house.
Had TPLink AX6000 router -- Visionary people had me change it to an access point (which dumbs out a lot of the router features). I have now changed it back to a Netgear 6700 -- also access point -- because it seems more reliable.
No real question here except kudos to the outages support people who spent a lot of time trying to help diagnose the problems. Just laying the problem for later questions.
