Hey, So I recently switched to Ethernet. I am using Linksys E8450.
I use SQM set to 150 Mbps up and down. Wheneverr I play Valorant, at times I lose the connection and it shows me the "network problem" at the top right but it get backs to normal in like 2 seconds but that's still a problem for me since I play more competitively.
I feel like this might be bcz the router is getting stressed? How do I find the source of the problem and how do I fix it?
At this point, it is hard to know where the problem could be -- it could be the router, it could be upstream. Could be something else.
But let's start with the basics:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

is it with Valorant only or all the games?
Anything found in logread when game chokes?
Add /etc/nftables.d/mssfixup.nft
Containing:
chain mangle_postrouting {
