Rollback WRT3200ACM to 19.x?

[anomeome]

Appears to be some errors in your above log that will need to be sorted. If > 1 SSID on radios be sure to set unique BSSIDs per.

i would try to reset to default.
start from the beginning, just use the first two radios, and make sure to set channel 36 on 5ghz, and leave all to default.

[napierzaza]

I decided to go one further.

1. I deleted the /etc/config/wireless file.
2. wifi config
3. wifi reload
4. Went to the LUCI config to enable the NAC radio without changing any setting

Result: It just says "wireless is not associated" and shows "disabled." This is just to launch an unprotected AP called "OpenWRT"

Is there something that would persist from installing 21.x even though I downgraded to 19.x? It doesn't seem to find the wlan0

I did a logread

Is there something that would persist from installing 21.x even though I downgraded to 19.x? It doesn't seem to find the wlan0

There should be no permanent changes.

I suggest that you reset the router to defaults, regarding all settings.

As mvebu moved to DSA, there are incompatible changes e.g. in network config ( including switch) config. If you have restored 21.02 network config files into 19.07, you will run into trouble.

Network, system and wireless are the most incompatible config files between 19.07 and 21.02.

If you want to copy settings backward , it is best to just use the old config file as reference in reconfiguration, and not actually use them.

[napierzaza]

I never actually copied anything between settings. I was mostly wanting convenience for my hosts and ethers but I just did everything fresh with no copies.

[hnyman]

what does the kernel log say, when you boot the device?
Are the wifi devices initialised properly?

[DanSman]

Maybe this can be helpful for you as well

WRT3200ACM (v21.2.0) - 2 bridge devices with different switch ports not working

That was it! Thanks for that! I remember setting the vlan on the switch (version 17 or so). I was able to just leave it as tagged. I did a little research on those 2. Now it's actually working correctly, right? I mean vlan untagged and tagged? There are 2 bugs on this device that I came across: Post 3 wpa3 bug Anyway, thank you all! Edit: I can't change to [Solved]. And I would like to add mk24s answer as a solution too. It would be great if there was a possibility to add 2 solutions.

I had to tick legacy on a 2.4ghz WiFi for one of my laptops. Which has only 2.4ghz. It worked on 19.7 or less without it but the latest 19 and 21 needs it.

[napierzaza]

Okay so a completely clean reset, and then the most minimal wifi configuration possible seems to have fixed this. I am not sure what happened but I guess I won't venture to change bandwidth or region or channel ever again. Will also wait for a few changelogs in 21.x to see if I'll ever consider upgrading again.

[hnyman]

Just be adviced that Linksys/Marvell/NXC stopped the mwlwifi driver development in early 2019, so the wireless in WRT3200ACM and WRT32X will be always broken regarding some wifi functionality: 802.11w, mixed WPA2/WPA3 etc.
