Why do TP-Link routers kick wireless users off and prompt for password?

Installing and Using OpenWrt
21

Sorry. I will post config again. I have an TP link MR3420 running OpenWrt 18.06.1 / LuCI openwrt-18.06 branch.

It's configured as AP. luci-proto-relay is installed. Frequently, after some hours, the router asks for wi fi password again.

I didn't undestand all your question. But I have just disabled legacy rates. How do I disable power savings?

Are your clients that connect to the router via WiFi that keep getting disconnected running Linux on them? If so, to find out what model of chipset the wireless adapter is can be found typically by running 'lspci | grep 802.11' in a terminal.

If your clients that connect to the router via WiFi run Linux and use NetworkManager, you need to do the following as root or sudo to disable power management for the wireless adapter on those clients:

touch /etc/NetworkManager/conf.d/wifi-powersave-off.conf

Then using your favorite text editor, add the following to that file:

[connection]
#Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
wifi.powersave = 2

Then restart NetworkManager using 'systemctl'
