Last week while traveling and staying in a rented room, I and one of the folks with me both had laptops with Wifi capabilities. The person from whom we were renting had wireless internet and said we could use her connection. There was no security on their router. It was an always-on satellite connection. I do not know the brand or model of the router. We would always receive a GOOD or VERY GOOD signal, but often, and sometimes for hours on-end, we would both receive an "UNABLE TO CONNECT" message when trying to connect to this wireless connection, even though it showed a GOOD or VERY GOOD signal. What might explain this? The only thing that I could speculate was that her internet connection was "down." so YES, we could communicate with the router, but could not get to the Internet because she was not connected to the internet. Is this plausible? Is there a better explanation?
