larry and I did some private debugging. The long and short of it is that his setup doesn't receive frames on antenna A, only on antenna B. Antenna A has like 50dB or more less signal: iwm0: energy In A -114 B -51 C -256 , and max -51 So my guess is it's either not connected internally, or (like mine?) it's hooked up through a bluetooth switch that we're just plainly not setup right. On mine, A is active and B looks like the above (-114). Imre/etc, let's look at what iwlwifi/mvm does for default TX antenna config and default bluetooth config. I think it's wrong. I think our hard-coded antenna (1) is wrong, and I think the antenna alternating in the rate table is also wrong. -adrian
