I've been saying it for some time now, but here's an article that sums it up nicely.

If you are currently using WEP or no encryption at all, your wireless network is at risk. Don't be fooled into a false sense of security that your WEP encryption will be an effective deterrent. According to this article (and several others that I've read), WEP can be broken in as little as 60 seconds, 5 minutes in a "worst case scenario".

If you would like to change to WPA security, you will need to access your router's web configuration page (typically done by opening a browser and putting the address of the router in the address bar) You can find your router's address by checking the default gateway setting for your AirPort in System Preferences > Networking. Configuration will vary by router model, but your documentation should cover the details. Once the change is made to your router and you've chosen a password, each client on your network will need to have its connection updated.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

Just to add, I know someone who works at Cinetiq, the UK R&D company, and he can break a WEP network in 45 minutes just using brute force, so I can well believe those figures.

I judge you when you use poor grammar.

First thing I did when I got my new router was change the IP, the SSID, changed the password to login to the router and switched WPA on.

My next door neighbour doesn't think that way to the point where I have printouts to prove he uses grokster. He hasn't put any security on, has opened the ports for P2P and still has the default SSID, username and password which basically means I can cause mayhem if I want

A friend of mine likes to say "The stupid shall be punished" - and that's true.

I cracked my 128-bit WEP key within 40 seconds on the MacBook Pro. Now let me say, yes WEP can be broken quickly, however one must capture some serious IV's before it can be done this fast. I had to capture around 900,000 IV's, which took around 8 hours of active collection in a slow network environment. Networks with users active will produce more IV's quicker, but it "might" take 1, 2, 3, 4 + hours to obtain that many. And yes, I agree WEP is no longer the secure method of securing a network.
