I am aware of the "Table of Hardware", but I specifically look for an OpenWrt-compatible WiFi repeater to be a WiFi-Intermediate bridging from my upstairs router WiFi to my downstairs PC WiFi.
Are there any affordable devices with multiple real hardware WiFi interfaces (on different channels) for this purpose, so I do not half my WiFi bandwidth?
you can use pretty much any dual radio router as a wireless repeater, connect to the source with one, retransmit with the other.
But doesn't "dual radio" usually mean that one is 2.4GHz and one is 5GHz?
For speed reasons I would prefer a device that support 2x 5GHz.
generally yes, but there are triple radio devices.
5GHz usually have issues with passing through walls (and roofs), I can imagine the 2.4GHz signal will be the one you'd want to choose anyway.
And how would a find a matching device?
It seems the "Table of Hardware" does not allow filtering by parameters like "dual radio", "ac WiFi", etc.
pretty much anything with a 2.4GHz and 5GHz band would be dual radio device.
Okay, how do I find a "triple radio" device?
Linksys EA8300, becoming an older model but it does have two 5 GHz ac radios.
I don't know if there are any triple wifi 6 (ax) routers yet.
get for instance a mesh node, like the Asus Lyra, it got one 2.4GHz radio, and two 5GHz radios.
Seems there might be support coming for the Orbi too - https://github.com/openwrt/openwrt/pull/3469
Netgear Orbi Pro support-booting from MMC
Another option would be powerlan adapters, openwrt support those as well.
Thnx mk24, was looking for that one

My DSL 250 is breaking down regularly during video conferences and it takes 2 minutes to re-establish the connection. I suspect that my currently used Devolo power line solution is the reason, interrupting the DSL line, therefore I am looking for WiFi.
Life has mysterious ways. Thanks to your tips, links and further research, I found that Meraki MR33 is OpenWrt compatible and has triple radio. And I just wanted to put that unused piece of hardware up for sale So now I need to find a serial adapter...
I think plan B would be the Asus Lyra MAP-AC2200, it only uses 7.2W compared to the 15W of the Meraki MR33. The Linksys EA8300 will probably require more power due to the 4 LAN ports, which I do not need.
