Quick Tip – Build a mini citywide wifi network

Work| Views: 1192

This tip has saved my ass more than once. If you are traveling with a smartphone, get the wifi password everywhere you go and connect your smartphone to the network, even if you aren’t using it at that moment. Later, when you run of out credit on your phone or don’t want to use expensive international data roaming, you have a little network of hotspots all over town. Even if the place is closed when you return, you can usually huddle near the wall and get some signal.
