Is this AP/sta or adhoc mode? It may be you are running low on memory bandwidth or cpu. I'd done a test over usbnet to the board and got about the same result. Does the wifi use the softmac layer? The changes toke made there on ath9k (see https://blog.tohojo.dk/2016/06/fixing-the-wifi-performance-anomaly-on-ath9k.html ) resulted in quite a nice gain in performance. Also the supplied antennas are not the best, you can get better antennas pretty cheaply via amazon. > In order to enable 2x2 MIMO on the board, you need to add a file > /etc/modprobe.d/wl18xx.conf containing the following line: > > options wl18xx ht_mode=default > > This might actually be an upstream bug -- the default ht_mode should > probably be "default" (duh), and the documentation for the "n_antennas_2" > module parameter is incorrect (it is documented as defaulting to 1, but > actually defaults to 2). > > I'll let you know if something breaks. Next time I boot mine I will add in all the changes you've figured out out! Thanks! > -- Juliusz -- Dave Täht Let's go make home routers and wifi faster!
