Terminating ethernet cable (Oooops!)

I just finished two fiber optic runs to my shop and added four more cams out there. I'm using media converters to convert the fiber back to copper at both ends. The cams were all running fine so I moved on to adding my AP. I installed 23 AWG solid copper CAT6 for everything and terminated the ends myself. It was only when I finished up with the AP install that I noticed the media converter was only showing 100 Mbps. My AP is capable of gig speeds. The ends tested fine as far as continuity but I decided to snip them off and reterminate. Same issue. I made a test cable and brought it into my office and connected it to my PC. It too showed 100 Mbps connection.

I never questioned the cameras because they were all working which makes sense as they only need 100 Mbps. Plus since I had a new POE switch connected to the camera media converter it was showing a full 1000 Mbps. I decided to buy new Klein crimpers and new RJ45 connectors. The new connectors were the three piece suit variety. The other connectors were the basic pass through kind and I used some crimpers I bought at Home depot years ago.

When the new stuff arrived I made a test cable and it tested fine and showed full gig speed on my PC. I reterminated the ends on my AP cable and it worked perfect at full gig speed. I then decided to pull my four cameras down out in my shop. I tested each cable run by connecting to the internet and using my new AP at the other end. Sure enough all four cam runs showed 100 Mbps at the media converter. So, I reterminated all four camera ends and they tested fine. The other ends are in a network cabinet connected to punch down keystone jacks. They are all now capable of gig speed even though it's overkill.

I think the problem was my old crimpers and the push down prongs on the connectors were only two tooth. I took a closer look with a magnfying glass and it appears that the old crimpers were not pushing the prongs down far enough. If you look at my photo, the new connector style is on the left, and the old passthrough style is on the right. On the passthrough connector it looks like the crimpers pushed down at a slight angle. Whats weird is they tested fine as far as continuity. Maybe some of the push down prongs were barely making contact??

Anyway, now I need to check all the camera runs at the house made with the same damn passthrough connectors and crimpers. I'm betting they are all maxed at 100 Mbps as well.

Here's the crimpers I bought and the new RJ45 connectors. I really like the load bar on the connectors.

And the pic of the new and old RJ45 connectors. Note the slight taper on the push down prongs on the right connector. They are all even on my new connector on the left.
