Good day.
Thank you very much for your time and patience.
Did you set up the TL-WA1201 as an access point?
Do you have a stable connection from the main router?
Have you checked both 2.4ghz and 5ghz have the same issue?
When the signal disconnected, did you still detect the wireless network but fail to connect, and any error message?
By the way, how far away is WA1201 to the home router?
If possible, please try to change the wireless advanced settings on the home router, such as channel 11 for 2.4ghz , channel 40/48 for 5ghz;
And please also try to reserve a fixed IP address for 1201 on the router;
Thank you very much.
