I recently learned to change the wifi channel to have better internet connection and speed. However, after i changed the wifi channel from the tplink app, the router reset itself when i turned it back on the next day and i have to redo the setup for the router. I usually turn off the router and modem at night and turn it back on the next day when i woke up.

I tried changing the wifi channel twice and both times ended up i have to re setup my router again.

Anyone have any idea what is the issue here?

Thanks.
