Unstable wireless network

Sat Nov 16, 2019 11:24 am

Hello,

For about 2 years I have been using the MikroTik RB951G-2HnD and a few months ago I started having serious problems with the wireless connection on all the devices. By problems I mean frequent disconnections and very slow speeds even in the room where the router is. I tried a lot of things but failed to fix the problem. To clarify that I understand very little about Router OS and all I do as settings is from articles, seminars videos on MikroTik's YouTube channel.

In the end, I decided to switch to MikroTik HAP AC² router, hoping that the problem would be because of a congested 2.4 GHz network (I live in a building with a lot of networks), anyway I would have gone to 5 GHz sooner or later.

The bad thing is that the some of the problems remain on the 5 GHz network. The range is very bad and there are disconnects again.

The router is located in the middle of the apartment and all devices are at most 8 meters away. The router is located on the desk with the computer (in front of the monitors), next to it is a ZTE device, where the optical cable enters and transmits to MikroTik.

I have a lot of Google Home devices (3 smart speakers, 2 chromecasts) that I connected to the 5 GHz network, 2 smart bulbs that I left on the 2.4 GHz network, as well as phones, tablets, laptops and more.

I attach photos of the settings of both networks and registered devices.

I would be grateful if you could help me find and possibly fix the problem.

Thanks in advance!

Try setting AMSDU Limit to 2048 and group key update to 1 hour.

So I should enable instead WPA EAP and WPA2 EAP?

It's a lot better now and I will stick to those settings. Will update if anything changes.
Thank you for the help!
