1) Yes. Try Belkin or NetGear<br>2) WiFi routers usually have DHCP and will allow you to connect to a web based config interface. No dial-up is needed<br>3) I don't know the dosage level. We are bombarded by signals everyday. I'd be worried more about FM/AM radio signals than WiFi signals. Although leaving WiFi on 24/7 may make it more succeptible to cracking, which can only be fixed by surgery.
