Poor wireless performance with RealTek RTL8723BE












0















I have a laptop with the RealTek RTL8723BE. Performance is poor with long ping times, dropped packets and often on wake the network manager will report 'connected' but nothing with get through, pinging the router will get nothing. Other devices on the network have no problems, Windows running on same system has no problems.



Here is output of various possibly useful things:

So, my question: how do I get this adaptor working reliably like it does under Windows?

          Try to channel the wireless channel from 1 to 11 and check the performance



          Check the frequency and channel



          sudo nm-tool


          nm-tool will list all of the visible wifi networks' frequencies.



          sudo iwlist frequency


          The command sudo iwlist frequency will give you a list of their corresponding wifi channel numbers.



          Now change the channel to 11 with the following command



          sudo iwconfig wlan0 channel 11


          Hope this helps!

          • Seems an odd solution, but gave it a go anyway. Got this for the last command Error for wireless request "Set Frequency" (8B04) : SET failed on device wlan0 ; Device or resource busy. Would assume as it's connected to a channel that as mentioned above is set by the router.
