It's just the physical properties of air transparency for radio waves and other typical materials for the houses
This happens once in a while. Firmware Version OpenWrt SNAPSHOT r22528-0c53801968 but it has happened on other builds as well:

Tried out channels above 100 as suggested earlier and they dont work at all, the wireless cards wont activate. Only channel 36 seems to work for 160Mhz for me, the rest wont apply
That may be due to either the country you're based in, that may not allow the use of those frequencies, or some radar in the vecinity that's disabling their use. You can check the latter in the log file.
Yup logs mention radar as the reason for not being able to apply
Hi, could someone please advise what can I do. I have flashed openwrt but the luci was not there. I was not able to configure the PPPoE trough terminal. Is there a way how to download luci package manually and scp it to the router?
P.S. these are my ISP settings (I have fiber): https://www.o2.cz/podpora/internet/pevny-internet-modemy-nezakoupene-u-o2#c-manualni-nastaveni-a124225
snapshots don't come with luci, you can add it downloading the proper ipk and installing it. ( opkg update && opkg install luci)
For your needs, something like this in /etc/config/network should work:
config device
option name 'wan'
config interface 'wan'
option proto 'pppoe'
option device 'wan.848'
option username 'O2'
option password 'O2'
option keepalive '5 1'
config device
option type '8021q'
option ifname 'wan'
option vid '848'
option name 'wan.848'
Some further fine-tuning (i.e. mtu or ipv6) can be done, but at least it should get you started.
You can use the online OpenWrt firmware selector to build your own package which includes Luci. For the stock layout, go to:
https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=mediatek%2Ffilogic&id=xiaomi_redmi-router-ax6000-stock
For the U-Boot layout, go to:
https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=mediatek%2Ffilogic&id=xiaomi_redmi-router-ax6000-ubootmod
Under the " About this build" heading, click on "Customize installed packages and/or first boot script" and just add luci to the installed packages. It will build a new firmware snapshot with luci included by default.

Thank you I will try this. Could you please tell me what packages are needed for luci. Is it ok when I just add luci there?

Thank you, I had there the interface section, I was missing the device section. Could you briefly describe what is this section for?
You need to enable VLANs (802.1Q) and create a device for the specific Internet VLAN, in which you'll be running PPPoE. That's what this section does.
For instance, if you want to add a new interface for TV (as per the link you shared), you'll have to add
config device
option type '8021q'
option ifname 'wan'
option vid '835'
option name 'wan.835'
config interface 'iptv'
option device 'wan.835'
and then configure iptv interface with the appropiate protocol and parameters.
Yes, just luci is alright.
Noticed that in a recent commit the MT76 maintainer has removed the MT753x driver, see here
Correct me if i'm wrong but isn't this the driver used to support the MT7531AE switch chip in this router?
If so maybe we need to steer clear of snapshots released after this commit?

So it appears the newer DSA drivers (from upstream) are used instead. I might hold off on flashing to newer snapshots though for the time being.

Yes but in my case they are not working like the previous one.

i have problem with wifi 2.4. the maximum speed I achieve is around 30-50 mbit/s. I changed channels and frequency between 20 and 40 mhz, no difference. what is the reason and how to fix it?
I'm using the latest snap.
wifi-device 'radio0'
option type 'mac80211'
option path 'platform/soc/18000000.wmac'
option channel 'auto'
option band '2g'
option htmode 'HE40'
option country 'US'
option cell_density '1'

config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'Nova'
option encryption 'psk2'
option key 'xxxx'
What is your device? It looks like your device only have 20MHz 1x1 support...
actually the problem was on my phone. I tested it on another device, no problem
