I'm looking to rig a powerful (fast) OpenWRT router, and notice (from other threads) that most of the relevant boards use off-board mini-PCIe WiFi cards, and are often sold with various Compex cards. As the ToH only lists the boards/full routers, I wonder which of the Compex cards are actually expected/supported to work with current OpenWRT.
Looking at the Compex site https://www.compex.com.sg/wifi-module/ they make a number of QualComm/Atheros based boards, ranging from QCA9377 to QCA9984 (roughly). They also talk up their QualComm QSDK based OpenWRT fork for their own boards.
What isn't clear is which of these WiFi boards can actually be fully used by standard OpenWRT.
For example their most powerful cards for 5GHz seem to be WLA1216V5-20 (narrow to fit in more cards) and WLA1216V5-23 (QualComm reference design, double output power (+3dB), but wider than normal cards). Both use QCA9984/QCA9994 4x4 MIMO.
Bundles with Main board+cards+box+ OpenWRT installed often use the cheaper cards such as WLE600VX (QCA9882 2x2 MIMO).
I would also need to buy a 2.4GHz card from the series of cause, so their support status would also be relevant.
(Note: Not really my first post, just the first after the forum was rebuilt).
