After reading these no network threads I decided to try the stainless steel mixing bowl idea as nothing else would work to connect the 770 to my 802.11g router at home. I borrowed the bowl from my wife's stand mixer and placed the 770 in it facing the router which was less than 12 inches away. Once I searched for a connection my network was immediately available and I connected while leaving the 770 in the bowl. Once connected I could use the 770 normally from anywhere in my home.

I'm sure one of my neighbors recently purchased a N router which caused my no network problem. Perhaps I'll invest in a travel size stainless steel bowl in case I run into this problem while out of town.
