Thanks, Comcast! I'll be working on the laptop and suddenly lose connectivity because the modem has shut down. I then have to reset it, and wait until it comes back online. Tonight, it happened while I was online competing for substitute teaching jobs, and I missed out on one because the garbage modem decided to stop working. Again, many thanks, Comcast! Your poor quality has cost me a day's work and $100 plus dollars. Nice work.
