Hello. I own multiple MikroTik devices and had almost zero problems with it, before this week.
Latest RB2011UiAS-2HnD-IN (v6.43.16) worked perfectly for almost 3 months. But these days I notice constant wifi drops without any reason whatsoever. Many devices on my network just stop seeing the Wifi broadcast. And some, while still connected, don’t have access to the internet or other computers. Here is a Google Spreadsheet with recent log - https://docs.google.com/spreadsheets/d/1TOLb1OfuMSuuXXXINr9su399I1XUNGBTfr3ALDYh08A/edit?usp=sharing
We moved to a new place, my network configuration was not changed, but 10 smart wifi lightbulbs were connected to the router. I am not a network specialist, your help is appreciated.
Well this is far from overcrowded, but it is one big mess. Those devices could all work nicely together, and share the available wifi spectrum with good performance.
Due to the disturbing “auto” implementations, and maybe some ignorance of the device owner, you have full destructive adjacent channel interference in the environment, instead of collaborating co-channel interference.
The AP’s are not that bad, but other devices are just as destructive.
You should only have 2412,2437 and 2462 as center frequency for 20 Mhz bandwidth (non interfering channels 1, 6 and 11). Zillion of documents and youtubes to be found on this topic.
There are some AP’s which do not comply, but they are weaker than -86 dB
However the client device at 2447 with -27 dB is a killer!
OK. This neighbourgs story is a well known situation. There are 2 ways to solve this:
Move to 5 GHz with all you can (see http://divdyn.com/docs/2.4-GHz-is-Dead-v1.00.pdf)
But your RB2011UiAS-2HnD-IN is not 5 GHz capable. Adding a hAP ac2 or even a hAP ac Lite would already give the needed extension.
But this is a cost.
Weed out this 2.4 GHz environment. What is yours in this list? (It could be much more than you think, the line 37 2447/26dB device is normally very close to the RB2011, or it must be unbelievable strong (dangerous and illegal). All devices with a signal lower than -86 dBm can be somewhat ignored. There might be enough room around 2437MHz . In that case the 2412 and 2462 do not interfere and can be fully ignored. Do not rely on “auto” frequency selection, pick it manually ! Almost always the case !
The 2011 is well-known to have poor wifi performance. We disabled wifi on all 2011’s that we manage around 3 years ago and installed alternate APs. I believe it is due to the wifi chipset myself.
Incidentally I had reason to use a 2011 about a week ago for 3-4 days. Even on 6.46, I still had the same problem with the wifi clients disassociating randomly. For my use it didn’t really matter, but I noticed that it still happened.
