Secure Your Wireless Network.

Update to my last, I think I have solved the problem but still not sure exactly what was the cause.

The day after my last post I found references to similar problems related to using IPv6, I disabled it and since then the laptop has a more stable wifi connection, but also no system freezes have occured.

For anyone reading this with the same symptoms heres a link to turning off IPv6...

I used a value of 20 (Prefer IPv4 over IPv6).

More evidence that securing your wireless network from wardrivers is essential...

The US authorities have charged 11 people in connection with the theft of credit-card details in the country's largest-ever identity theft case.
They are accused of stealing more than 40 million credit and debit card numbers before selling the information.

The 11 suspects are alleged to have obtained card numbers, account information and password details by driving around neighbourhoods and hacking into wireless equipment.
