OpenWRT One. 25.12. One device cannot connect with mixed WPA2/WP3 mode

Installing and Using OpenWrt

Hi All,

I have printer. Brother DCP-T425W. When my 2.4GHz SSID on OpenWRT One device is set to mixed WPA2/WPA3 encryption method is set that device cannot connect. Changing SSID to WPA2 only makes the printer connect straight away.

As OpenWRT One is THE most stable wireless experience i ever had i suspect that the printer is acting.

I would like to ask if there any parameters which i could add to /etc/config/wireless that i could try to keep mixed mode and get that printer connected? I would like to keep AX mode on 2.4GHz.

Thanks for any help.

don't use mixed mode ? it's not more secure than WPA2.

just create an exclusive wpa2 ssid for those problematic devices, and keep your main ssid wpa2/wpa3 or wathever you prefer.

A quick web search for "Brother DCP-T425W WAP3 mixed" provides a lot of results describing issues with this model connecting. This website seems to have a dead link to a Brother webpage that described your problem as a known issue.

This same issue arises with the Pixel 10; it will not connect if you have OpenWRT set to mixed OR WP3-SAE ONLY mode. Connects fine with WPA2.

This is new; mixed mode DID work prior to the 25.12 upgrade. NWA50AX-Pro.

It appears something is wrong with the WPA3/SAE mode implementation in this release.

Just curious: was it working with mixed mode in 24.10?

Yes. 24.10.05 and prior worked perfectly in mixed mode. I noticed this after the upgrade in that the Pixel was falling back to 2.4g (which I have configured for WPA2 only because of some older gear that has issues with mixed mode) and when manually asked to connect to 5g it refused and said the password was no good – which is definitely not the case.

Looks like that is indeed the same bug…..
