I would like you use the device on the Repeater Mode. So I connected it to my WIFI router (2.4GHz and 5GHz). I connected my PC to the RE450 via a network cable, and now opened the TP-Link page on a web browser. I went to the 'Wireless' Tab and pressed the 'Extended Network'. Now, I would like to disable both, the Extended 2.4GHz and Extended 5GHz, but the user interface wouldn't let me. So, if I disable one, then the second one is enabled. I could not manage to disable both. This could be good if I were connected wireless to the RE450, but I am connected hardwired, and would like to disable the WIFI Extended Network. Can this issue be fixed by TP-Link?
