Rollback WRT3200ACM to 19.x?

There is a little known mvebu-specific way: OpenWrt does not use the pretty large "syscfg" partition, where the Linksys OEM firmware stores intermediate files.

OpenWrt only uses that partition to store the config backup archive .tar.gz during sysupgrade. And after the sysupgrade the archive gets deleted.

But otherwise the partition is unutilised, but it is always mounted at /tmp/syscfg. That looks confusing, as /tmp is ramdisk, but yes, there is a permanently mounted large flash partition at /tmp/syscfg. And that is common and visible to both dual-boot partitions.

So, you could could make a backup from your settings (with the sysupgrade script) and store that to some new directory in /tmp/syscfg. You can then later easily restore them (with the sysupgrade script) to the then running partition.

Okay so I was able to flash over to 19.07.8, using the factory image was the trick and I didn't get the erorr I did previously. Now it's really weird because my AC wifi just doesn't work anymore. It originally worked fine when I was using 19.07.8, then I had my issues with 21.x, and now being back on 19.07.8 has somehow broken it.

hnyman · September 23, 2021, 4:13pm

Are you sure that you have not restored "newer" configs from a future firmware (21.02) to the old 19.07 ...

Some options do change between versions, e.g. the wifi band option is new in master and 21.02, but is not supported in 19.07

Example from my routers:

This is from a new style config (master): option band '5g'

config wifi-device 'radio1'
        option type 'mac80211'
        option path '1a143000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0'
        option band '5g'
        option cell_density '0'
        option htmode 'HE40'
        option channel '44'

While this is the old style: hwmode '11a'

config wifi-device 'radio0'
        option type 'mac80211'
        option channel '36'
        option hwmode '11a'
        option path 'soc/1b500000.pci/pci0000:00/0000:00:00.0/0000:01:00.0'
        option country 'FI'
        option log_level '2'
        option cell_density '0'
        option htmode 'VHT40'
        option txpower '21'
        option disabled '0'

hnyman · September 23, 2021, 4:16pm

Note that you can regerate the 19.07 default wifi config with wifi config, which only works if you have no /etc/config/wireless file.

root@router1:~# cd /etc/config/
root@router1:/etc/config# mv wireless wireless.backup
root@router1:/etc/config# wifi config
root@router1:/etc/config# ls -l wireless*
-rw-r--r--    1 root     root           707 Sep 23 19:14 wireless
-rwxr-xr-x    1 root     root          1030 Sep 19 22:41 wireless.backup

There is now a new "wireless" with default contents. (in addition to your old settings in wireless.backup)

napierzaza · September 23, 2021, 4:20pm

config wifi-device 'radio0'
	option type 'mac80211'
	option hwmode '11a'
	option path 'soc/soc:pcie/pci0000:00/0000:00:01.0/0000:01:00.0'
	option channel '56'
	option htmode 'VHT40'

config wifi-iface 'default_radio0'
	option device 'radio0'
	option network 'lan'
	option mode 'ap'
	option key 'xxx'
	option ssid 'yyy'
	option encryption 'psk-mixed'

This is what I have now, it looks like the old style. When I reflashed I made sure to exclude keeping the config, but it seemed inconsistent. At least the IP restarted with OpenWRT named AP and the IP reset as well

hnyman · September 23, 2021, 4:25pm

you are missing the country and txpower options. (I do not remember if they are mandatory)

what does you kernel and system logs show about wifi (and hostapd)? Usually there are explanations if you do "wifi up".

napierzaza · September 23, 2021, 4:44pm

I added country code and power, it seemed like they were optional but I can't be sure. Still doesn't work.

channel 56 is dfs, so make sure that you set contry code FR,and leave txpower to auto

anomeome · September 23, 2021, 5:15pm

CC, and TX power are ignored on the rango, but if the third radio is in play it has to be in agreement with CC of the mwlwifi radios.

napierzaza · September 23, 2021, 6:07pm

Okay that's weird I guess I will choose another channel there really isn't any info there.

As for the third radio it's not enabled so I guess that doesn't matter?

napierzaza · September 23, 2021, 6:45pm

Changing to a different channel seems to have no effect regardless of whether my computer should be able to connect I would assume that LUCI would tell me it's on and operational though no?

anomeome · September 23, 2021, 7:02pm

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.

anon4457646 · September 23, 2021, 7:24pm

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 · September 24, 2021, 2:10am

I decided to go one further.

I deleted the /etc/config/wireless file.
wifi config
wifi reload
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

hnyman · September 24, 2021, 5:13am

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 · September 24, 2021, 5:29am

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 · September 24, 2021, 6:08am

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

DanSman · September 24, 2021, 6:26am

Maybe this can be helpful for you as well

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 · September 24, 2021, 7:01am

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 · September 24, 2021, 7:38am

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.
