WiFi disconnects when multiple devices are active
Hello
Ever since I've updated to the recent FW version, I'm facing the following issue:
Multiple devices are connected to WiFi: laptop, phone1, phone2.
Watching videos on my laptop. When some internet activity starts on the phone1 (e.g. video playing, apps downloading for update, etc) the WiFi disconnects for every device. This is a bit random but with downloading files, e.g. for an app update, I have been able to reproduce it every time.
This is not the Internet disappearing; this is the WiFi network disconnecting and reconnecting in about 5–10 seconds.
I believe this is the same issue as here: Archer C80 - wifi keep disconnecting - Home Network Community (tp-link.com).
I have tried to optimize settings and to reset the router to defaults, which didn't help. I cannot revert the firmware version.
Thanks for any help.
