Hi all,
we recently bought a FriendlyARM R5C router to use in a mobile robot. What we'd like to also have is a DBDC capable WiFi card. I flashed the device with 24.10 snapshot, latest kernel, and tried two ath11k-pci based cards (this one with WCN6856 and this one with QCA6391). None of them show two phy devices. Any ideas if I am missing something and they should work or are they just the wrong cards and I should get a diffferent one?
Thank you!
I think you need MT7915/MT7916 based card....but power consumption and heat dissipation might be an issue.
Thank you! I got an MT7916-based card (AsiaRF AW7916-AED, https://asiarf.com/product/wi-fi-6e-m-2-ae-key-module-mt7916-aw7916-aed). Works like a charm. Just plugged in, loaded kernel module, second phy shows up and works. I got 1Gbs throughput over 5GHz WiFi working and parallel upstream over 2.4GHz with 300Mbps. Really cool!
I had considered going down the same route but wasn't convinced that an M.2 card the size of the AW7916-AED would fit in the R5C.
Any chance you could upload a pic so we could see the tolerances?
It doesn't fit, not even close. To get it to work, I got an M.2 A key extension cable and, using this, I am 3D printing an additional enclosure for the card and the IPEX pigtails (three needed). I will share some pictures once done.
It seems there are no M.2 cards with 2230 size (the only that would fit inside the R5C) that can do DBDC.
The AsiaRF card is size 3052, i.e. the typical size of WWAN cards. Much bigger, and also with a heat sink. But has A/E keying, like a regualar WiFi card. WWAN cards seem to mostly have B keying.
