Edit: I have found the reason for the low speeds.
My router is set to automatically set the Wifi channel and I have many other wifi’s around me.
I played around with the settings and set the channel manually. If I set a high channel number like 13, I get only very low speeds. If I set Channel 1, I get instantly 77Mbit of 150 possible Mbits.
The funny thing is, that most of the Wifi’s around me use channel 1. I always thaought it would be better to use a channel which is not used by other wifi’s.
My router at somepoint decided to switch channels, thats why the problem appeared out of nowhere.
Problem solved.
Hi,
I have been using Raspberry for more than a year now with a Edimax EW-7811Un Wifi and OSMC and everything was running fine. I even used to stream my desktop screen via moonlight app ner-realtime to my raspberry. The wifi connection was more than good enough for it.
But out of sudden, I only get very low Wifi speeds now. My router shows me that the raspberry is only using: 2 / 51 Mbits 2,4 GHz / n / 20 MHz WPA2, 1 x 1
I have changed nothing. The distance to my router and the location of the raspberry have unchanged.
Restarting etc does not help at all.
The WIfi Works flawless in my laptop. I have also bought another new Wifi dongle from TPlink cause I thought, maybe the Wifi dongle is broken, but I get the same low speeds with the new adapter.
Therefore I believe that the problem is some Software sided problem on the raspberry.
Strange thing is that my router shows me that the connected device could use 51 MBits, but is only using 2 MBits.
Apart from the slow wifi speed, my setup is working flawless.
With that low wifi speed, the setup is useless.
What is the problem here? Anyone can help?
