The more you mess around with packages and settings, the more rabbit holes you'll find.
I've heard about various problems on this platform. I have a few of these devices, one at home. For me, it has been THE SHIT for several years and has served me faithfully. Incidentally, in terms of download statistics, this device is one of THE MOST popular ever on openwrt. Today topped only by some xiaomi e-garbage So given the sheer amount of them out there, it is not impossible that a few of them are twitchy. Mine have been great. And given all of this Wifi6, 6E 7, 8, it's all mental masturbation, 5GHz on this has been enough - for me.
It's worth looking at what devices connect to it via wifi - I have had virtually no problems with iphones or android. Just run vanilla settings, and 5G wifi is great.
I run most workstations wired to my router. The only devices on wifi are basically mobile phones. So my demands are not that great.
If you're going to saturate your 200mbits link and run 200 wifi clients and VPNs, start looking for a multi-core or multi-cpu platform, already on DSA and with offloading working. If you are just bridging packets to wifi, this device can serve you well for a few years yet, provided it's not a twitchy one.
