Hi!
I've a RB951G-2HnD at home, I use WiFi for some Mac, iPhone, Windows PC and others, but my new Raspberry Pi 3 does not connect to the WiFI, in settings I do not see Mikrotik SSID. I tried to set manually the parameters, but nothing change.
The WiFi chipset in Rpi3 is the BCM43438, I've upgraded Debian Jessie but nothing change.
The firmware in RB951 is 6.22, Do I have to upgrade?

Thanks!

Most important thing, what channel do you use?

Good question!

2412Mhz
Band 2GHz b/g/n
Channel Width 20MHz

Do you thing I've to change something?

Wow! Solved changing channel from ch11 to ch6!
Thanks for the idea!
