Missing channel (like 157) about 8821au-20210708 HOT 6 CLOSED

Let me duplicate this issue and see if I can figure out what is going on. Have you connected successfully using any of the channels that do show?

This paint has not dried on this driver code. There are a lot of changes and editions from the last version and this version has shown in my testing to be much better than previous but with big change comes the probability of some bugs.

from 8821au-20210708.

I have the same issue with the previous version.
I can connect to all the channel in the list.
I tried with other distro without success.

Hmmm...

Unable to duplicate the problem here so far. Here is what I have done but first are details of my test setup:

Alfa AWUS036ACS usb wifi adapter based on 8811au

WiFi router changed to channel 157, 80 MHz channel width

As you can see, it is connected to myMT76-5g. I ran iperf3 and did some surfing. Performance is very good.

Verdict: Unable to duplicate the problem. It works here.

Recommendations:

Don't use "iwlist", use "iw"

Run $ iw phy phy0 channels and post the results. Change phy0 as needed.

Run S iw dev and post the results.

Run $ sudo iw reg get and post the results.

Oh, something else. I did a lot of work on the driver last night. Recommend you run $ sudo ./remove-driver.sh followed by deleting the driver directory followed by a reboot and full fresh installation. That will make sure we are on the same code.

from 8821au-20210708.

Oh my bad I so sorry.
I had the old driver from aircrack-ng.

Sorry for the issue, I close it and continue to test this driver.

No problem. It happens. I can use all the help I can get testing this driver so please give me reports as you have time.
