Intarwebs giving me problems...

For those commonly seeing fast responses from me, our internet connection at home has decided to be very unreliable. I'm trying to figure it out tonight when I can talk with the service people at Roadrunner. It's not our computers (given that I use the same laptop at work for various things AND at home, and it has no trouble connecting with the work wireless, my AirCard is clearly still just fine), so it has to be something on their end -- either the service, or their modem.
