My Fingers are crossed
I am not sure why, but I can now access the internet on my Mac again. Apple suggested I call Linksys even though they probably wouldn't be much help. The Linksys rep admitted up front that they only offer limited support for the Mac, but the router should work. We went thru the routine of setting up a new network, etc. It didn't appear to help. The very last thing we did was install the latest firmware for the router. I didn't check the Mac immediately, but about 1 hour later, I came into the room and the Network Status window was displayed. It should that both of the Parallels connections were green and amazingly the Airport was also green. It said that I had an IP address and was connected. Sure enough, I was able to connect to the internet. I am typing this message on the Mac side now.
Not sure if the firmware update was the trick or if I will lose connectivity at any time, but I will keep my fingers crossed.
I really do wish I knew why it started working again.
Thanks
Rod
