Wireless insecurity

I’m not generally a fan of wireless networking. If you have the option of using a cabled network, you should probably take the option. This is partly because the radio spectrum available is shared between users, and so will never be as fast as an equivalent wired network; and partly because a wireless network can be cracked by somebody nearby and you have no easy way of knowing it’s happening.

Lifehacker has an article on cracking WPA protected networks which is worth a read. The motto: Turn off WPS if your router supports it. Ideally, permit access to systems by MAC address (most wireless routers support this). (If you’re using WEP… don’t. Switch to WPA2.)

I should add that wireless networking does have its place, but you should work on the assumption that if you’re using wireless then your network may not be secure.
