Hello everybody! I know this thing is not related to Mikrotik. I have got an LG G3. I have not found anything this device's 40 Mhz support and maybe on this forum some people have some information about it.

I have got an RB 751 width 20/40Mhz mode on 2.4 Ghz. I know on 2.4 Ghz the 40 Mhz most of the time is unstable.
My LG G3 connected at only 65/65 Mbit/sec. My Samsung laptop connected at 150/150 Mbit sec and sometimes i could achieve 70-80 Mbit/sec with FTP servers. This would be very good with LG too. I have disabled energy saving mode.

So do you know anything about LG's 40 Mhz support ?

Thank you for your replies.
