Hello. I want change a r11e-lte to Quectel EM12-G
But need a adapter mini pci - m.2
Anybody installed? Thank you

You might want to look at:

The key detail is the miniPCIe-to-M.2 adapter needs to be "Key B" type.

The 2nd question is whether a particular adapter's added height would still fit in the wAP R.
