If you happen to be in Berlin, you can get <a href="https://www.hotspot.kabeldeutschland.de/" target="_blank">30 minutes of free WiFi</a> in quite a lot of places from a KabelDeutschland™ HotSpot. Unfortunately, each connecting device gets only 30 minutes of free internet per day. On a completely unrelated note, I will talk about changing the MAC address of your WiFi card in Windows 7. I must, again, emphasize the fact that these two topics are in no way related. <a href="https://blag.nullteilerfrei.de/2013/08/25/kabel-deutschland-hotspots-and-wifi-macs/#more-2086" class="more-link">Do you want to know more?</a>
