Stick up cam Elite has "poor connection" over PoE -- how?

I’m having the same problem and I’ve tried everything. With just a few feet of ethernet cable plugged into my switch, the switch lights up indicating 100 Mb connection. Video quality is good. When moved to the 100’ ethernet cable suddenly it lights up only as a 10 Mb connection which is terrible. Video is very grainy and cuts out often. App indicates “poor connection.”

-Thought it was the connectors so crimped new ones on several times. Didn’t help.

-Figured it had to be the solid copper cat 5e line so ripped it all out and bought solid copper cat 6. Same problem. Crimped new connectors several times. Didn’t help.

-Carried laptop 10’ up the ladder to see what speed it would connect at. Switch indicated great connection of 1000 Mb. How can this connect at 1000 Mb so quickly but ring stick up cam can’t even get 100 Mb?

-Thought it must be a defective camera, brought a different one up and plugged it in. SAME PROBLEM

If you figure it out please post your solution! I’ll do the same.
