AC750 RE200 Range Extender Connection Issues
I have been using the AC750 RE200 since July 2023 when I purchased it and all had been great. When I looked at it today on the app the RE200 no longer exists and the extender just flashes green on the power and 2.4ghz and 5ghz buttons, the WiFi symbol just flashes red before they all go out and then it resets. None of the buttons will go a solid green and when trying to reconnect to the router it just makes a high pitched sound but nothing happens. I have tried numerous sockets as well as resetting the extender with no luck. The SN number is 22331M8004794
I cannot see any of the TP link wifi addresses on my wifi links available.
I have only owned this for about 10 months so disappointing if this is failed already. I purchased through Argos, I have the credit card payment but not physical receipt. Is it possible that someone can assist.
Thanks
