Ok- Long story short - my office is in my back yard. I have direct burial Cat5e around the whole perimeter of the property and feeding into my office. Two nights ago I started getting interruptions in my internet. It would work for awhile then cut out, then work again. For some genius reason I thought it was my ethernet cable - I had crimped them on the copper wires and not grabbed the sleeve. Even those this same cable had worked for two years - I clipped it while still plugged into the router and rebuilt the end. Since then I have not been able to connect to my router. I keep getting the yellow warning sign in my taskbar alerting me that the network cannot be found.

So I went to Microcenter and bought a LAN Cable tester. I've rebuilt the cable end in my office about 8 times. Every time I run the cable tester #6 doesn't light. It goes through every other light in the set of 8 just fine. Always #6.

Ran a giant 100ft cable across my backyard from my office to my router - works perfect. So I know it's not my Ethernet adapter.

Can cat5e cable just "go bad"? Is that a thing? What am I missing here?

Any advice/help would be greatly appreciated. I'm tearing my hair out over here.

Two thoughts

1. When you crimped the cable while the other end was connected to the router, you may have damaged that port if you created a short with the small amount of juice running through the cable. I'd test with that 100 ft cable and make sure all the ports on your router are sound.

2. Assuming your router ports are solid, you've narrowed it down to the cable. Recrimp both ends, not just your office end, ensuring proper wire positioning and all that jazz. If you're still getting the problem, somewhere in the cable is the fault. Pull the cable and either inspect it for damage, or make life easy and run a new cable through. Since you're doing a new cable run, might as well go Cat6 or 7 and plan for 10Gb speeds for a future upgrade.

Azran - thanks so much for the suggestions. It works! I must have jiggled something loose on the other end of the cable. I went inside to the router, rebuilt the connector on that end and plugged it in - everything is working fine now. No more connection interruptions either!
