I don't wish to jump into conclusion to request you to change your router since you are using or still using Wi-Fi 5 device. By default, that Tenda AC2100 should be to handle 300Mbps, both over wired and wireless. I believe the model is
Tenda AC19, right? When you face internet outage, what you normally do? Do you reboot the router and modem manually, or just reboot the router? Normally, in my case, I never rebooted my modem (tm -unit) given to me unless there is power outage in my area. I only scheduled automatic reboot in my own router, which is D-Link DIR-X3000Z (retail version). Any cheap routers, with proper reboot program practice should provide not the best experience, but below-average, average internet experience.
Normally, most networking experts will recommend users to upgrade the firmware issued for specific models of routers (if available).
Upon checking, your router model's last firmware patch issued should be on
2023-01-11, according to Tenda Global site:
AC19v1.0 Firmware V16.03.10.11.

lol just realized my router actual name is Tenda AC23 and not AC2100
i just wait for the internet come back when theres an outage, and i usually have the internet back in 5mins
thanks for checking the version for me, mine is at V16.03.09.17_multi which is the latest version for my AC23

unifi modem BTU is fine no problem
ohh this tenda ac2100 crap due low spec
try getting TP link AX73 or ASUS Router gaming will be handle
actually i just realized it cant be the routers, because my wifi(downstairs) and wired(upstairs) actually are two different routers connected to the modem(downstairs), so the problem has to be from the modem onwards to unifi
also i just checked with the CS on twitter and asked about the service outage that i had today, and this is what he replied
"Upon checking, today only has 1 time cut off, but the connection seem like stable now. If you're still facing unstable connection, I can help to reset the internet port. Do you want to proceed?"
and when i asked about whether the problem is on unifi's end or my end, this is what he replied
"From our site, it shows the line disconnected due to lost carrier. In a networking context, particularly related to RADIUS (Remote Authentication Dial In User Service), indicates that the physical connection or signal between the device and the network access server (NAS) was lost, leading to a disconnection. This loss could be due to various reasons, including a dropped signal, a device being powered off, or a network issue."
