Omnia WiFi extension recommendations

I am at my second Omnia, now with WiFi 5 and 5G modem on the ground floor of our new home. The first floor has weak signal on either 2.4 or 5GHz and I am already close to the maximum transmit power (16 and 30 dBm respectively).
Since there is Ethernet cabling available, I think the simplest would be getting an AP with bridged Ethernet mode.

I like Ubiuity’s offering and quality, the U6 would be perfect, but their standalone setup mode will not support 802.11r/k/v.

Any other recommendations would be appreciated. Should I go with another OpenWrt-compatible device? Or get a dumb AP?

Get ubiquiti and flash it with OpenWRT?

where is the first? :slight_smile:
and i´d definitely use something openWRT, or get a used mox perhaps?
you could also think about upgrading the omnia to wifi6; this improved the coverage of my omnia so i could disable the wifi on my mox. but, as always, ymmv.

The first Omnia is serving as a VPN exit point for the second one. I was never satisfied with the Omnia’s WiFi reach, which is why I am looking to complement it with something else.

It seems that the U6+ is supported by OpenWrt, so I ordered it. I am curious if I can make a decent WiFi roaming set-up with it and the Omnia.
