I've lost the internet twice this week with my computer. My computer insisted everything was ok with the network connection, but I couldn't connect to any websites. Most surprising was that I was able to send an email. or at least, Gmail thought it sent the email. Who knows, it may just have been confused about that. The router and my phone and Fire (wireless) were ok, as was my work laptop (not wireless). Rebooting the computer restored its connection. I'm guessing FIOS burped sometime during the night and everything successfully restored their connections, except my computer. Which only thought it did.
