Just bought a 24" Imac and am having trouble connecting to the internet with a wireless router. I use Verizon dsl and have a Westell modem and router combination. I spent a long time the day I bought with the Verizon representative and after updating the firmware on my modem got it working. Now several days later it has stopped working and I'm not sure how to fix it. When I go to network diagnostics it cannot find the network but it is working fine on this computer. Any help as to how to either figure this out or start from scratch and try again would be appreciated.
