That reminds me... Years ago I had the battle of all battles with my cable co. I complained that somehow there servers where failing after having some much throughput go thru the modem. I made them replace the modem, the line outside. The checked a bunch of there equipment. It stopped for a period after they replaced the modem a second time. It later can back in a few months. I decided to strip down the machine, and low and behold a capacitor had blown it's top and had leaked on the PC board.of my external NIC. I guess it would build a charge over time and shut the card down. I replaced that card and have never had any other issues of anything similar.
