We've been using the Archer MR600 V2 as an NBN WIFI router very successfully for the last 6 months. We normally connect through the 5ghz channel because it is much faster than the 2.4ghz alternative. In the last few days we have not been able to connect to the 5ghz channel. It shows up on our devices (iphones, ipads, macbooks) but when it's selected we get the message "Unable to join the network TP-Link_73D2_5G". I've tried forgetting the network then starting again on each device. I've tried rebooting the router. Nothing seems to work. No-one has changed any settings on the router. Does anyone know how to fix this?

Hi, is the wired connection or 2.4G connection still working fine?
Please login the web interface of the MR600, try to change the 5G WiFi name and Password, then try to connect the 5G WiFi again.
You could also try to change the 5G channel from Auto a static one such as channel 36, 40 etc.

Hi. Thanks for the suggestions. Changed the name and password for the 5ghz channel but no connection. Changed from auto channel selection to 36. Again, no connection.
Message continues to be "Unable to connect" even though my phone and computer, etc, can all see the channel.

Hi, thank you very much for the reply.
May I know if you tried factory reset the router as well? If not, please have a try.

Hi. Thank you again.
I rebooted through the app. I also disconnected from power for a minute. Are these the same as Factory reset? If not, what is the correct procedure please?

Hi, thank you for the reply. The procedure you've done is to restart the router instead of factory reset, please note that factory reset is to reset the router to default settings, so your previous configuration will be lost.
How to do factory reset: with the router powered on, press and hold the reset button on the back panel of the router for about 10s until the power LED start flashing.

Hi. I have done a Factory reset now and the same problem continues on all devices. We get the message "Unable to connect" even though the devices can see the 5ghz channel.

Hello. Thank you for all your advice. The firmware is the current version so it appears we've exhausted all options.
I will contact the engineer on the email you've provided.

Just a follow up - TP-Link Engineer was very thorough trying to resolve the issue for us. In the end decided it was a physical fault with the router and is arranging a replacement under warranty for us.
Stuff breaks down. Can't help that. But great response from TP-Link Community and Engineer makes the process much easier. Really appreciated.
