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?
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.
