maximus Posted January 29, 2016 Share Posted January 29, 2016 Ok im pretty sure this is a Mac os problem rather than with my router but the wifi card in my sig does not want to connect to wifi if its channel is set to 40 mhz ( 300 Mbit ) i can only get it to connect when the channel is set to 20 mhz. Booting into windows and ubuntu connects fine with 300 mbit. Does anyone have any ideas?
