and just 6h later, the amazon.uk bargain is sold out.
Just to make sure:
does anyone know, are there any regional restrictions hard-coded anywhere in the WiFi chip or config partition ? (like as in the dreaded Linksys WRT series?)
e.g. if I buy it via UK, will it be a UK model made for UK WiFi regulations? Or is there just one EU variant, sold everywhere in the EU, just with different power adapters?
UK and EU/ETSI regulations are identical, plus OpenWrt allows overriding the regulatory domain using the country option.

Place it in a file e.g. target/linux/generic/hack-5.15/999-WIP-mt7531-move-core-pll-init-disable-port-5-sgmii-p.patch and rebuild kernel.
I switched to the 5.10 kernel / rc5 stable earlier last week or so - is this still applicable?
Is there a wiki/dev readme I should follow (absolute noob here) to ensure I don't mess up the process?
replace hack-5.15 with hack-5.10

I've created a pull request https://github.com/openwrt/openwrt/pull/10349
with patches for 5.15 and 5.10 to fix the 100 mbit limit.

Would be great to get those patches into the 22.03 release branch as well, if possible.
RC6 rolling out now.

do you think the release can come out this month, and is there such a big difference between rc5 and rc6 because for the moment RC5 works very well on my belkin thanks
RC6 download online: https://downloads.openwrt.org/releases/22.03.0-rc6/targets/mediatek/mt7622/

wrong topic ! 
@nbd I'm finding over time the 5ghz wifi radio gets stuck at slow speeds 100mbit vs 800ish with the newer builds.
After installing rc6, I was just poking around and saw this in my rc.local
echo 437500 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq
echo schedutil > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
and wondered if above workaround was still needed, or if some of the fixes that @daniel outlined were implemented to mitigate the boot hangs people were experiencing?
