To me these are strange results. I have this router and (only) a 300/300 Mbps connection and it seems to be routing that with sqm cake (I think) with ease (it gives full internet speed with speed test with 5ms ping time and A+ in buffer bloat test) and the internet feels very responsive and stable, surprisingly may be even better than my x86 with OpenWRT vm. 2.4 GHz works extremely well (gives 100mbps in speedtest on 2x2 20mhz close to the router and unlike my other mt7621 router my phone does not complain about there being no internet when being away from the router). 5Ghz signal is somewhat weak, although speeds are ok when being close to the router. I didn't really test 5Ghz and had not used 160 MHz (my only ax device with 160mhz is my desktop, which seemed to connect fine to the network but the signal was low and it is hardwired anyway). My phone which supports ax seemed to connect fine and gave my full internet speed and showed WiFi 6 logo, didn't test it much further. Overall, I hadn't noticed any instability with wifi (and hadn't heard complains from my family members). My only issues are that 160 MHz connection is shown for all WiFi 5/6 devices no matter the actual bandwidth in LuCi, +17 dbm signal strength (for some reason the same happens on 5Ghz radio on redmi ac2100) and I had once seen the WiFi bug out and my phone not being able to connect to 2.4ghz about a month ago, though that might have been due to DAWN bugging out again, and I hadn't seen any of that on the latest snapshots. Overall I'm quite happy with this router (apart from 5Ghz weakness)
Interesting, as I do get exactly the opposite results 5GHz being more reliable - however I just use it as a wireless (Wifi 6) bridge (as in Client-Mode).
Flashed it with latest image from
- So far everything seems to be solid/stable (only 12 hours uptime tought).
- Hidden SSiD & PMF does seem to work (2.4GHz).
- Client-Mode (on 5GHz) works.
- Multi SSiD doesn't seem to work in Client-Mode (on 5GHz) tought.
In Client-Mode the AX-Mode seems to work out of the box (?) - at least it does connect with 4x4 80mhz at roundabout 1900/1900 and the main AP does also list it as using Wifi 6.
Thanks a lot. This smal line makes my Sunday great:
wireless.radio1.htmode='HE80'
The Wifi 6 ax is activated on my new Ubiquiti Lite U-6 and runs.
The GUI just shows AC, but the client says AX 
Hi there
I just tried this with my 8450 and I received a "Invalid Argument".
Do I have to add the device, if so, how?
Thx
Hello, I tried to install openwrt on this router again, but it failed, the link you posted in here doesn't work anymore either, do you have a good link? Thanks, Reinoud.
Link works.
