Most secure setup for Netgear WGR614 Wireless Router

WEP is basically useless except for the casual user who doesn't know anyting about wireless. WEP can be cracked in minutes, and measures posted on a BBS about securing WEP, if that is what they said, can be disregarded. Same with not broadcasting the SSID. The SSID is still in the beacon and can be seen without any particularly special tools.

If however you own client hardware, or AP hardware for that matter, that doesn't support WPA or WPA2 then that is what your stuck with. MAC filtering, or some Router/AP combos will filter by IP ACL's. Turning off SSID Broadcast etc... That's about as good as you can do. Ports are already blocked. Can't speak to what you heard or read but if they actually said/wrote that you should block ports then well, they really should be ignored. I suppose there may be some SOHO routers that have ports open and you could close them but it's unlikely. The opposite is true. NAT Routers should block and you have to manually open them if you want to do something using that port. Running an FTP server on one of your machines for instance. You'd open port 21.

If your concerned about wireless security, honestly, then go out and by contemporary hardware that supports a mechanism that isn't pitifully easy to break. Buy WPA capable devices. WEP, MAC filtering, disabling SSID broadcast, if you know what your doing, is barely a bump in the road.
