I have an old Scientific Atlanta modem. Been using this fine for a few years now. Last couple of days it has been crashing under light use, such as watching youtube videos, loading large picture files, downloading files. You can browse the internet fine as long as you do not encounter any large images. Resetting the modem fixes the problem straight away to let you browse again. This happens when you are connected straight into the modem, so is not a router problem. Any suggestions are welcome, Thanks!
