Hope full support with MT7927 wireless card.
Will make a note!
Upstream patches for Mediatek MT7927 :
I wonder if such a card could be added in the Openwrt One case… but I don’t see any card with 3 antenna connectors
Probably yes but OpenWrt One already has MT7981 & MT7976 as its WiFi PHYs.
More likely, MT7927 can be used with an Intel N100 x86 OpenWrt router with M.2 add-on interface, Raspberry Pi 5 SBC, or Banana Pi R4/R4-Lite when AP mode support becomes mature for the new driver later on.
Sure the N100 would be able to provide power enough to run it?
Probably, but if the goal is to enable 2x2 6 Ghz 320 Mhz channel (around 5.7 Gbps throughput) , you need a router / PC with at least a 10 Gbit port / NIC to fully utilize this huge bandwidth.
I imagine N100 can drive 10 Gbps throughput but the difficulty would be to find a N100 SBC with a 10 Gbit port available. For N150 and higher model, you can find a 10 Gbit port more readily available, for example, Protectli VP2440.
I was referring to A(mpere), not CPU power.
That’s probably more of a power supply issue, I imagine.
PS: Looking at the blog article on patch submission:
Someone already tested it on a Banana Pi R4, but running into negotiation bug at 320Mhz BW.
Guess this is something still to be further tested & confirmed.
It appears this mt76 issue documented the usage of new firmware files:
Yeah, I've got a Debian 7.0.10-1 (2026-05-27) and it's detected by lspci, but no joy with wifi.

Edit: He's also using the 7925 patched to 27, that's not my case since I'm trying the firmware released from MT.
The mt76 issue mentioned Ubuntu 24.04.4 + kernel 6.17 , maybe the Ubuntu Kernel is heavily patched.
Don't know how fast the latest patch is backported to Debian Kernel, but if it sticks to mainline Linux mostly, you may need to catch up on it later. See Git Kernel: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/log/?qt=grep&q=mt7927
