Hello,
I have the TP-Link Archer C5 AC1200. As I understand things, v1.x is eligible for OpenWrt, however v2.0 is not.
The sticker on the bottom of my device says "Model: Archer C1200(US) Ver2.0." From this page, it looks like the 1.x model has 3 external antennas, whereas the 2.0 model only has 2 external antennas.
I believe I have V2.0, yet my device has 3 external antennas. Has the wrong sticker been placed on my device? Is the web page incorrect? Perhaps I have a newer model? I would appreciate any help resolving the discrepancy.
