First guess would be the WIFI channel being changed automatically on the router to an invalid channel. Change your router to manually select the channels rather than having them set to "auto".
That will eliminate that as a possibility.

TP-Link is the brand of your router, you will need to mention the model of said router. While here, see if you can use the version number found under your router/router package to locate a support page and see if your router is pending any firmware updates.

Considering your sister's end is what's affected, might want to see if your sister's laptop is pending any BIOS updates, has any OS updates and if reinstalling the WiFi adapter's drivers in an elevated command, changes the issue.
