I have a linksys wireless router and connected to it is a DSL modem and 2 (wired) PCs. We also have a laptop elsewhere in the house that connects wirelessly. I know the neighbors can see the wireless network, so my questions are, what do I need to do security-wise to make sure people can't steal bandwidth or see files? I really struggled setting up WPA and WEP originally, so I gave up, thinking I would just not explicitly share any sensistive data. Was I wrong about this? Recently, someone said I should filter the MAC addresses, so I added the laptop's MAC address(es) to the filter list today. Everything seems to work fine still, so any need for anything else?
