Windows 8.1 dropping/losing Wi-Fi/WLAN connection, limited internet access, frequently re-connecting to router/access-point

Title in german:
Windows 8.1 verliert ständig WLAN-Verbindung zum Router / Eingeschränkte Verbindung

A while ago my wife's Dell Vostro 3500 running Windows 8.1 started to frequently drop the Wi-Fi connection to the router AVM Fritz!Box 7390 (sometimes once a minute), requesting a new IP-Adress by DHCP, but still showing limited internet access.

Things I tried, which did NOT fix the problem:
- Updating to latest drivers
- Switching to an AVM USB Fritz!WLAN Stick N v2
- Assignng a static IP to the network adapter

How-I-fixed-it:
I was able to fix the problem by changing settings for the WiFi-Adapter in the Power Options and disabling IPv6.

First:
Windows Key + R, type control panel,
go to Power Options. Click Change Plan Settings,
click Change Advanced Power Settings, then Wireless Adapter Settings,
then Power Saving Mode. Change the Plugged in option to “Maximum Performance”.
If this is a laptop, you might have On Battery option and set it to “Maximum Performance”. Restart computer.
I found thsi hint here:

Second:
In the properties of the Wi-Fi network connection, DISABLE Internet Protocol Version 6 (TCP/IPv6), as described here:

Wi-Fi problems with Windows 8.1 are described in many threads, here are links to the ones i found:
