Mikrotik – Optimizing Wi-Fi performance

Published on Author gryzli1 Comment

I was getting very bad Wi-Fi speeds with my Mikrotik 951G-2HnD routerboard.

Here are the few steps I executed and got really better performance while connecting through Wi-Fi to the internet.

Choose the least used channel frequency

I have Android based phone, where I was able to install WiFi Analyzer, which helped me decide which is the least used frequency channel around me.

The channel could be changed by the Mikrotik WEB GUI from here:

Web Gui –> Wireless –> wlan1 –> Frequency

 

Choose channel width

In my setup I’m using channel width: “20/40MHz HT Above” , and it could be set up from here:

Web Gui –> Wireless –> wlan1 –> Channel Width

 

Set wifi distance to “Indoors”

The most significant improvement in router wi-fi operation was from changing this option.

You can change it from here:

Web Gui –> Wireless –> wlan1 –> [Switch to advanced mode] –> Distance == “indoors”

 

Change Tx power to 17 DB

I set this up from here :

Web Gui –> Wireless –> wlan1 –> [Switch to advanced mode] : 

Tx Power Mode == all rates fixed

Tx Power           == 17db

 

Change ht-amsdu-limit to 2048

Web Gui –> Wireless –> wlan1 –> [Switch to advanced mode] :

HT AMSDU Limit   == 2048
