RB951G-2HnD Bad wireless speed

RouterOS Wireless Networking

Hi,
I Use a RB951G-2HnD.
Wired is the speed good but wireless is the speed bad.
The signal strength is ok (between the -58 and -68
But the speed is poor.
In Winbox I seed a speed of 72Mpbs at the max.
All my devices are 801.11N

The settings in winbox:
Mode: ap bridge
Band: 2GHz-only-N
Channel Width 20/40MHz HT Berlow
Frequency: auto
Wireless Protocol: 801.11
Antenne Gain: 0
DFS Mode none
HT tx Chain: Chain0 Chain1
HT rx Chain: Chain0 Chain1

All other wireless settings are default.

Make a spectral scan to see if the band and especially the extended channel is really free. Change the frequency accordingly.

Signal levels are important, but more important parameter is SNR which tells us if there Noise isn’t too much. So as Jarda suggested, try different channels. If noise is too high switch to 20 Mhz channel and try again.

Enable wireless-fp / wireless-cm2 pacakge!

Try to change position of 951G. Signal might reflecting in many directions which might affect throughput badly so yes - try different locations and keep away from metallic objects.

Thanks for this great reply.
I will try this all and let you know.
But how can I make a spectral scan?

If I run the command:
/interface wireless spectral-scan number=wlan1
I See a lot of frequencies and after that I see DBM and after that I see Graph.
How to implement this and what is best frequency to use? Where there are less “:” and “.” or where there are more “:” end “.” Or where De DBM is ?
