OpenWRT 25.12 - wireless issues with working config in 24.10-SNAPSHOT

[lamelogin]

I installed 25.12-SNAPSHOT on a mt6000. I’m having issues with my wireless coming up, I believe due to my complex network setup. lan and wan networks are working well. I can connect an Ethernet cable directly to router.

If I downgrade back to 24.10, things work fine again.

You didn't share enough of your config... most importantly, the wireless config file. Let's see the complete output of:

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):

Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless

@psherman , I've updated the first post with the files asked for. below is the ubus output, but it reflects v24.10 as this is my home router that I need. it was 25.12 when I have the issues:

24.10-SNAPSHOT

why exactly are you using a 24.10 snapshot, instead of stable ?

[lamelogin]

openwrt-24.10 and 24.10.5 are are pretty darn close at this time. I'm not an expert, but I don't think that is pertinent to my issue, is it?

[frollic]

24.10 and 25.12 are using diff kernels, 6.6 vs 6.12, AFAIK.
I see no reason to run 24.10-snapshot.
keep in mind snapshots should be considered betas.

[lamelogin]

This sounds a little familiar, maybe? I don't get the softbrick, but I do lose wireless, which I believe is due to a dependency (which I need help to figure out)

Previously working network config fails after upgrading to 25.12-rc1 on mt3000

So I tried upgrading my mt3000 that acts as as a bridged ap with multiple vlans from 24.10 to 25.12-rc1. That resulted in a softbrick. Resetting the device and doing stuff step by step, I get stuck as soon as I try to add the vlans from the previous config, I lose network access to it (which, lacking serial console, is painful...). Working: bridged ethernet like so config interface 'loopback' option device 'lo' option proto 'static' list ipaddr '127.0.0.1/8' config gl…

[lleachii]

Or maybe because there are more than 1 bridge?

Is there a reason you created additional bridges with no PHYs?

[lamelogin]

@lleachii , I don't know the answer to this: ".. is there a reason you created additional bridges with no PHYs..". Probably because I don't know what I'm doing?

A few years ago I used Dr Google to create multiple WiFi access points on separate VLans (networks). One for IOT, one for kids, one for guests, etc..

Is there a document i can use/read to better set this up? Note, this has been working for years now; not that it's the right way to do things, as you're pointing out.

[frollic]

Do https://openwrt.org/docs/guide-user/network/wifi/guestwifi/configuration_webinterface

[lamelogin]

@frollic , thank you sir. Will read and better understand.

Note: the first sentence says: "..create empty bridge..". My first thoughts are, isn't that exactly what I did for each network I wanted?

[psherman]

Add the bridge_empty option to the bridges like this:

config device
        option name 'br-iot'
        option type 'bridge'
        option bridge_empty '1'

config device
        option name 'br-guest'
        option type 'bridge'
        option bridge_empty '1'

config device
        option name 'br-briana'
        option type 'bridge'
        option bridge_empty '1'

If that doesn't solve the problem, a few other recommendations:

• Don't use sae-mixed in general -- it's best to use either WAP2 (psk2) or WPA3 (sae).
• Remove the last 4 lines here:

@lamelogin

config wifi-device 'radio1'
        option type 'mac80211'
        option path 'platform/soc/18000000.wifi+1'
        option channel 'auto'
        option band '5g'
        option htmode 'HE160'
        option country 'PA'
        option noscan '1'
        option cell_density '0'
        list hostapd_options 'ssid_protection=1'
        list hostapd_options 'ht_vht_twt_responder=1'
        list hostapd_options 'he_twt_responder=1'
        list hostapd_options 'enable_background_radar=1'

• Delete this:

@lamelogin

config wifi-iface 'wifinet9'
        option device 'radio0'
        option mode 'ap'
        option ssid 'new'
        option encryption 'sae-mixed'
        option key 'xxx'
        option wpa_disable_eapol_key_retries '1'
        option network 'lan'
        option max_inactivity '1600'
        option disassoc_low_ack '0'

• It's generally also recommended to use the same SSID for a given network across the 2.4 and 5G bands. That is to say that you allow the client devices to dynamically select the band based on their own internal logic based on the signal quality.

[lamelogin]

@psherman you're a genius! This resolved my issue: "option bridge_empty '1'"

Will also take a look at the other recommendations!
