If you've been using WPA encryption for your wireless connection, it may soon be time to move to WPA2. It seems the key exchange process for WPA, called TKIP, is cracked, which will allow people to access your wireless network. This could pave the way for leakage of the data going over these networks too, although that encryption has not necessarily been broken as of yet. Moving to WPA2 should be simple since most routers and devices now support it. And no one should be using WEP.

This might not be such a big thing for home network, although you never can tell what your neighbors are doing with your data. I'm of the better safe than sorry crowd myself, so I switched to WPA2 with AES encryption today. I haven't had any problems connecting my devices.
