5Ghz Connectivity Issue
2020-08-07 06:43:37
Model: RE200  
Hardware Version: V4
Firmware Version: 1.0.6 Build 20200708 Rel. 47302

Hi! I bought TP Link router  C6 AC1200 V2.0 (US) and TP Link extender RE200 AC750 V4.0 (UK). Both have OneMesh feature also smart connect. Also both of them upgraded to latest firmware. Now the problem is the RE200 cannot find 5Ghz network from my router. The only way it can if in my router i set the 5Ghz channel to 36/40/44/48. Doing this all my device can find 5G but my Samsung S9 cannot. Anyway you can help me?

@Blue1234 

Good day.

Thank you for your time and patience.

Due to the CE certification, RE200(UK ) V4 only supports 5Ghz channels:

band1 (36 40 44 48)

band2 (52 56 60 64)

band3 (100 104 108 112 116  120 124 128 132 136 140)

(band 2/3 are DFS channels.)

while for the US version of C6 V2, the supported 5Ghz channels are:

band1 (36 40 44 48)

Band4:149-165

So, since RE200 does not support band 4 like channel 149-165, so it could only see C6 when the router is on channel 1;

For the Samsung S9, is there any way you could check if the smartphone could be modified to support band 1 as well?

 

Really sorry for the inconvenience.

Thank you very much for your understanding and support.
