Internet drops multiple time a day, power cycling modem brings it back
I have a personally owned ASUS SB8200 that's connected to a Linksys Velop mesh network. It worked flawlessly for several months when I installed everything. A couple months ago I'd lose internet on my network a few times a week and power cycling the modem would bring it back. It's now up to dropping multiple times a day.
When I lose internet I can continue to ping devices across my network, and I can get the internet back by only power cycling the modem and not any of the Velop nodes, so I think I'm zeroing in on it being the modem or something upstream. I did find some other odd behavior - to get to the admin screen on the modem I have to remove the ethernet from my modem->router, hardwire it to my laptop, then power cycle them modem. When I'm done if I plug the ethernet back into the router I won't have any connection on the router until I power cycle the modem again.
Here's the info I got off the modem-

Ended up being a bad connection at the street. A tech came out and fixed it.

Most of the downstream power levels are low / weak and some are out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
In an effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, etc. Splitters should be swapped with known to be good / new ones to test.
Also check the coax cable for any damage such as cuts, nicks, kinks, sharp bends, etc.
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Good luck with it !

As stated, you may want to get a tech out to investigate this.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.
Good luck !
