Klein Tools VDV826-703 Pass-Thru™ Modular Data Plug, CAT6, 50-Pack (ASIN B076PRM7W8) 2. Klein Tools VDV226-005 Compact Pass-Thru™ Modular Crimper (ASIN B07R3GK9FQ) 3. Soft Plastic Ethernet RJ45 Cable Connector Boots by Copapa (ASIN B07219KGC4) 4. H!Fiber 1Gbe Ethernet Network Adapter (ASIN B074PPRQQK) I’m using CAT 6 UTP (23 AWG) that I bought from a local home center. 1. I found the Klein Tools VDV826-703 Pass-Thru™ Modular Data Plug, (CAT6, 50-Pack) to be easy to use. This is my first-time using pass-thru connectors, and I have mixed feelings, but that’s not what this is about. The 23 AWG wires fit in snuggly but did require a bit of convincing to pass thru. They are more expensive than some others that are available, but I know these will work perfectly, especially with a same brand crimper. 2. The Klein Tools VDV226-005 Compact Pass-Thru™ Modular Crimper did its job flawlessly. The insulation is held tightly in place, the crimp felt secure, and the pass-thru wires were cut perfectly flush. I still need to try this with cheap plugs, to see if they are cut just as flush, but these work great with their own. 3. While I don’t usually use boots, I decided to give them a shot as they make the wires look more “finished”. I purchased the blue Soft Plastic Ethernet RJ45 Cable Connector Boots by Copapa. While they didn’t cost much, they were very soft and fit okay. I wish they were a little tighter around the wire, but that can vary from brand to brand. Overall, I’m happy with them. 4. Once the cables were completed, I plugged them into a H!Fiber NIC (Intel I350-T4 chipset). They all fit nicely together, even with the boots. That network card is not the V2, and that was expected. The V2s are harder to find and there are no performance differences. The revision was made to fix a slight power surge during power-on. The network card performed flawlessly with pfSense and I was able to configure two LAGGs with LACP support. One to a Cisco managed switch, and the other to my cable modem (SB8200) but I’ll save those for a different review. This card is working perfectly. ## Features - ✅2.5Gbase-T NIC: Single RJ45 Port support 2.5Gb/1Gb/100Mbps, 2.5x Faster than 1G NIC.
