5ghz wifi bug spotted After updating to 23.05 rc2 ub mi 4a 1gen

5ghz wifi did not work

Can you provide clearer information and details.

e.g.

  • can you clarify what device you're referring to (if I had to guess, your shorthand refers to the "Xiaomi 4a 100M"?)?
  • use full sentences
  • what version did you upgrade from?
  • did you keep settings when upgrading?

EDIT - I found a reference:

Device gigabit 4a mi router
I was on 22.03.5 and after seeing the announcement that 23.05 in on rc1 i flashed that on my device and find 5ghz are not working i can see that on the admin panel but my phone or laptop can't find 5ghz so i switch back to 22.03.5 and now everything is normal as usual.

Yes i put that when i flashed and 5ghz did not work.

Yes i keep my settings and i also keep my settings when i come back from 23.05 to 22.03...

#does not have any overlaying packages.on which o flashed.


Boughtanother router today but same issue with 23.05 that 5ghz are not working i have to revert back to 22.03.5 and it is also working well.
Now i have 4mi router 4a gigabit with openwrt.
So a stable 23.05 firmware is important for me.

Here is a boot log

I have tried again and same issue no 5ghz wifi on

I think previous boot log might help figure out the issue thanks.

Set the country code to your actual country. Both radios must be set-- to the same country-- do not leave one unassigned. Use a channel number instead of auto. For initial tests, choose a channel which is not DFS in your country.

I have done that already bit did not work.
channel 36 is allowed in India for Wi-Fi 5GHz.
I try that but did not work.

ACS means Automatic Channel Selection, you will not have those if the channel is set to a particular one instead of auto.

No the boot log is when i switch back to auto. But trust me i have tried with 36 channel and it did not work but this works when i am in 22.05

If you saved settings during the upgrade, go to the CLI and rm /etc/config/wireless and reboot to generate a clean new wireless default file. Then add your country and channel numbers and configure an AP.

I can't do it right now as it was not working i just switch back to 22.05 sorry๐Ÿ˜”

Do you have same router can you confirm thqt it woeks on your system.

Yes have tested it- version 23.05.0-rc1:

  • Country set to IN, channel 36 works.
  • Country set to IN, channel 52 (a DFS channel) does not work.
  • Country set to US, channel 52 (a DFS channel) works.

Just installed rc2
The issue is in auto mode 5ghz never shows but in 36 channel i can see wifi 5ghz
Which is not a issue in 2.4 i can see it working in 2.4 ghz in auto mode how to resolve it

In channel auto mode channel stays 0 but manually selecting channel makes it work



It appears to be a bug even in rc2 but if i go back to the 22.03 wifi 5ghz works well in auto mode and shift to a open channel whenever required @mk24 have you lookinto this

Yes I've already tested and can confirm that channel 52 does not work with the country set to IN but does with it set to US. The table at Wikipedia says that channel 52 is allowed in India, though restricted to indoor use with DFS. Maybe there is something related to the really poorly documented indoor flag?

But in 22.03 firmware i find auto mode correctly switch between channels correctly but with 23.05 selecting auto it stay disable and on 0 channel i think it is a bug as it does not happen on 22.03. What you think.

Either that, or it is stricter implementation of the indoor / outdoor restrictions of some countries.

Try adding option country3 '0x49' to both radios.

# The third octet of the Country String (dot11CountryString)
# This parameter is used to set the third octet of the country string.
#
# All environments of the current frequency band and country (default)
#country3=0x20
# Outdoor environment only
#country3=0x4f
# Indoor environment only
#country3=0x49
