It is very rare these days that I get permission to talk about what I'm doing, but today I did! Somos Internet has been designing and building their own MT79 based internet router and bridge for the past few months. They engaged me to take a look at the reference board, and we were really pleased to see how well all of OpenWrt, not just the make-wifi-fast fq_codel bits, was working nowadays.

That was last month. This month, they got back the new boards with a new antenna layout, and the 5ghz performance at range is terrible. I confess that I no longer have even the slightest grip on how to go about debugging and improving antenna performance - are there beamforming variables worth sweeping in the mt76 driver? A piece of test gear we could use to see what is going wrong? A design tool for antennas? A debugging strategy for antenna placement?
