hi, my range extender doesnot pickup 5ghz channel of my main router which is running on channel 149. Range extender does not pickup the 5ghz signals even though i can see signals on my phone. Also there is no option to change the range extender 5ghz channel to 149 or any other channel, its only stuck on channel 36. I have seen many forums with people having this issue, also i am not using this RE in EU so there should be an option to change the channel here. My previous tp-link router also had faults and i bought this new one but i am not able to use the 5ghz because of this channel limitation. Please how can i change this, this is very important.
