i have set my router up and is running and i have been enjoying the amzing advantages of wireless internet from my laptop (eg sitting out in the garden with the laptop). anyway, i decided not to put WEP security on. however, i put on a mac filter and then hid the access point. anyway things are going well but my nextdoor neighbour bought my laptop and that has wireless. so i abit worried that he may been able to access the net from my network. would he be able to and also would this system of protecting my wireless work on all OS's. i know MAC OS is rubbish at network sercutiy. anyway thanks for reading.
