New cable?

Available at Home Depot, probably Lowes, probably Best Buy, definitely Amazon, and probably several other sources in most cities.

Putting new ends on isn't tough, but I'm not going to recommend it for someone for a single shot. You'll have to buy the ends, know what sort of cable you have (cat5 and cat6 technically should use different stuff for the ends), have to buy a tool, etc.... When I make them, they work 99% of the time. Maybe 1% I have to cut the new end off and put another end on. I have worked with folks that were maybe 50/50 at getting it right the first time. I've actually managed to remove an end and reinstall the same, previously installed end without the tool to do that many, many years ago when I was poor and not yet in IT, and that worked.
