Same problem in Eastern PA with a Belkin wireless router!
It is not a computer-specific problem because it occurs on both our desktop and 2 laptops at the same time.
In the past 3 weeks, it's been several times a day that the little yellow triangle with an exclamation point pops up next to the network icon on the taskbar, and we can't connect to the Internet due to "limited connectivity".
Found out that this has also been the case with a friend who lives a mile away and also has Verizon.
Incredibly annoying to have to power cycle my router every few hours....
What are you using to connect your Belkin to the Internet?
