      That happens. Faulty equipment is usually the last thing you suspect--unless all the lights are off.

      Last year there was a time when I couldn't stay on the internet for more than a few seconds. I tried everything including getting someone to get my power boosted through the socket. Turns out all it was was a broken modem.
