Wireless hardening

hmm.. if these providers (E.g. M1) is managing all the wireless infrastructure, they should be abiding by govt regulatory policies. but it's always voice down to end user, so it's better to have endpoint protection at ur laptops.

most of us hooked up to wireless@SG all across Singapore, esp at Mac, so just wondering if it's really safe? at home, what i did is to secure my wireless router by limiting to mac address filtering, is that enough?
