I dont really need extra seurity cos I live in the country, but just wondering how much safer is WPA2, and woulld WPA be quite safe if you used like a 60-100 leter/number string?

Cos apparntly hidden SSID and MAC Address filtering is rubbish, cos ppl can get past those easy if they know what there doing.
 
The longest passphrase I've seen a router allowing is 42 characters.
As far as I've seen brute forcing the passphrase is the only way in, with either WPA or WPA2.
 
They are almost the same thing and as far as I know neither can be hacked, apart from via brute force as tolien suggested.
 
mine allows a passphrase this long..

abcdefghijklmnopqrstuvwxyz1234567980abcdefghijklmnopqrstuvwxyz1 :p
 
well ive just changed my password/string to 62 long, the bulk of it is......... qetuowryipadgjlsfhkzcbmxvn9753186420_phil.. noticed what Ive done there guys? Cool hey

The basic difference is that WPA uses TKIP encryption and WPA2 uses AES encryption, the principal reason why older cards cant support WPA2/AES is that AES uses hardware to encrypt data transmissions, TKIP is software based.
 
additionally WPA is susceptable to MIC attacks. Effectivly a client sends two malformed message integrity check packets. When the AP receives these it thinks it's under attack and shuts down for 1 minute.

This happens to me a lot as my good ladies' laptop doesn't like my IP phone and when they're both switched on it breaks the wireless network, though I think that's a weird bug more than an attack :(

WPA2 has this problem fixed as much as I understand it...
 
cool I wonder if my router shuts down if it thinks its under attack, but its getting quite dated now, its a D-Link G604T. Sometime I might upgrade to the latest d-link router on the market.
