Few Noob Questions About Networking

[Larnica]

Hiya.

Hope you dont mind me asking a few basic questions

1) I have a Wireless Router which uses a "WPA-PSK Secruity". I'm just wondering how often I should change this?

2) How do I connect my computers to my Wireless Network with the SSID Broadcasting Turnt Off? I have to put in MAC codes and SSID and WPA-PSK manually I assume, no idea how to do so.

3) I have Firewall/Anti Virus but I dont think they protect Wireless, does this matter as im using a WPA-PSK Key.

Many Thanks!!

Great!

Thanks for your information!

Should I invest in Wireless Secruity? or will normal Firewall/AV be okay, as I think advertised wireless secruity products just help protect the router and the WPA-PSK key, as it says on the box only compatiable with certain routers.
