Hi,

I have a home gym in the garden and need to replace an old powerline extender. I have bought a tp-link AC2600 as a replacement. I have two questions!

 1) Would I be better with a powerline extender, we have new electric cable running to the office and thick walls, so might be better than a wifi extender? Maybe the tp-link AV600 or AV 1000?

2) I have set the AC2600 up and seems to work okay. Blue circle on when running on 2.4GHz. However, sometimes switches to 5GHz and so the blue circle turns red- weak signal? When I did the set up I selected both 2.4GHz and 5GHZ. Should I reset it to just connect to 2.4GHz ?

Main use in the gym is Smart TV (you tube) and mobile phones. Our router is Netgear and is on 5GHz. Thank you for your help.
