Ok thank you. Can I manually change some configurations to restore the previous transmission power limits?
Yes, I have 3 different devices (1 tablet and 2 cell phones) that showed that problem connecting to 5G band and with 4.8.3 op24 firmware. I tried everything I could (even a long contact with Glinet support), but only solution was installing vanilla openwrt (I also didn’t have that problem with 4.8.3 stable release, but I needed some additional functions). Last communication with support was that engineers would check info that I sent to identify the problem.
No, you can’t change transmission power limits on GL.Inet firmware as these are coded at the firmware level and are not editable beyond those set.
You can change the channel numbers though, which may help if you are in a congested Wi-Fi area.
Very strange, thank you. Sounds like I need to give sick openwrt a go. Bit of a shame as I do like some of the features from glinet, but that was why I picked this router model!
You can replicate almost every feature from gl.inet firmware (and many more) on openwrt. Some of them will just require more work to implement, but LLMs usually help a lot on these things.

Thank you, will give it a test!
If I'm not wrong, I can access openWRT through the official GUI. From there, I can only adjust the transmission power limit up to 20 dBm (~100 mW). Is it possible to go beyond that with version 4.8.3?
Mostly not, the OpenWrt setting can't overwrite the hard limit set by the Wi-Fi driver.

On Reddit users say that switching to 4.9 and setting country to USA or Spain in Luci, solves the problem.
Can anyone here confirm or deny?
No, that doesn't help, no matter which country you set, it remains a firmware bug
Assuming you tested it: Thanks for the reply.
(Btw: it’s not a bug, it’s a “legal feature")

Depending where you are, that will reduce your signal strength on 2.4GHz.
Depending on your location yes.
For a country in EUROPE for example, the transmit power allowed on 5GHz is far higher than 20dBm.
I understand GL have said well our antennas have 3dbi gain so we have had to peg it back. Fair enough, but it’s now too weak in my opinion.
I have an ISP supplied router which has significantly stronger signal strength, with internal antennas, compared to my Flint 2 running 4.8.4.
It is right next to my Flint 2, same WiFi channels, same bandwidth allocation.
I only notice the significant weakness in speed and signal strength on 5GHz though.
On 4.8.3 everything is fine.

Is the issue specific to Flint 2 or does this run through all their routers? If the latter are there any other brands where this isnt an issue?
The solution is to disable SKU. SSH into the router and execute:
sed -i "s/^SKUenable=1/SKUenable=0/" /etc/wireless/mediatek/mt7986-ax6000.dbdc.b0.dat /etc/wireless/mediatek/mt7986-ax6000.dbdc.b1.dat; wifi down; sleep 3; wifi up
Backing up the .dat files is recommended.

This is what I have been saying all along but one user harping on about the 3dbi antenna gain.
Just like you I have tested 2 stock routers that do not external antennas and they still have stronger signal than the Flint 2 on 4.8.4 an above in exactly the same location.
So my answer would be the power on 5ghz is too low for Europe and specific regions or the antenna calculation they have done is not correct.
How can other routers perform better without external antennas than a router with external antennas, Does not make sense whatsoever.

I don’t think that external antenna and antenna gain are synonymous; my u7 pro has antenna gain mentioned in specs but it has no external antenna.

This is most probably clearly the issue, the 3db gain they have taken off for the antennas is what is causing the drop off on signal compared to other routers that don't even have external antennas either that or these that are on the Flint 2 are clearly not doing anything for the signal.
