From March next year most McDonalds restaurants throughout Australia will be providing free wifi. Australian IT reports it will be “family friendly” as sites with pornography, terrorism etc. will be blocked. But at least that is better than the expensive options they offer now.
Of course the use of open wifi can be useful but many people don’t realise it can also be dangerous.

wow! scary! we have a wireless network linking 2 PCs here at home, maybe I should check their security … thanks for the post, Jim.
Hi Adam
Yes it can be a worry. Turning on the highest level of security that your router provides with a strong password is essential.
