https://dev.openwrt.org/log/trunk/target/linux/ramips. As you can see,
nothing after r46891 touches upon this issue.
the newer kernel might be the cause

radio (`mt7602`), and the referenced fix definitely improved things there.
If that's not your experience, provide statistically relevant signal
strengths before and after. As of now, both 2.4 and 5 GHz radios have
comparable strengths (in my case, roughly 62-65 dBms at 12 m).
2.4 varies between 80% and 90% while 5GHz is 71% at most, usually about
65-67% and while transfering data it falls down to 62% sometimes even at
58%. so the strengths are not comparable.

> Finally, you cannot reasonably expect a diminutive $27 AP to perform
like one with discrete external amplifiers, especially using the 11n radio
on the SoC. The 11ac radio has enough bandwidth, and the 'mt76' driver
performs rather well nowadays.
the AP price has nothing to do with this. i can assure you that. because
with proprietary drivers both wlans give between 80% and 90% signal
strength. to be even more sure about this i observed displayed signal
strength on my notebook for 5GHz and i noticed this interesting fact: in
rare ocasions when connecting to 5GHz network i get 82% of signal strength
at the moment the card connects and only a second later it drops to 70% or
68%, probably it gives full strength for a short time until the radio is
wrongly recalibrated due to the bug somewhere in mt76 code or missing PA
trigger.
