Unstable router operations

I have CRS109-8G-1S-2HnD and several Caps on endpoints for wifi after upgrading to ROS V7 lately having issues with stability on interface ports link downs occour randomly the worst is when watching youtube or some streaming service it drops very often for 12-20 s than it comes back and this is happening very often i checked every cable forum no sollution to be honest worked.
I have a modem before router that is bridged.
When i look at interface list all ports were active and randomly they would all in the same time go from several kbps directly to 0.
CPU load is low, there is 50 meg of ram available i attached supout.rif.
At the moment i went and set up a switch and conected everything to port 2 to monitor what is going on but it is the same. This is frustrating please help.
supout attached is not a zip its rif just rename it.

EDIT MOD: supout removed. Shouldn’t be used on public forum, only for support

ROSv7 is too generic.
Different versions of 7.13, 7.14 and 7.15 (besides latest-latest 7.16) have been object of alternate reports of instabilities on Wi-Fi.
From what has been reported, 7.14.3 seems to be the safest bet or - at least - the better “base”.
