I had brought a Netgear wireless router and about 50' of Cat5E. However, the reason the Netgear was scrapped became obvious. Although the WiFi on it was working fine, the WAN port apparently was not. So, I got a nice signal from the Netgear but a signal to nowhere.
And on that note, I'm full circle--back to the middle of nowhere. I don't plan to return to the hinterlands for a while, so I've terminated the Verizon Wireless account. (As always, Verizon Customer service was quick, knowledgeable, and efficient--no joke.) There was at least one other bit of good news. There were many other folks at the family reunion, many sporting AT&T phones, mostly iPhones, and they were able to get a cell signal much of the time at the north end of the house.
