CAT 7 Cable not Recognized by Nighthawk R8000

Recommended Posts

Posted · Original PosterOP

Going from a Google Fiber Modem to my Netgear Nighthawk R8000, I have a 100ft CAT 7 cable. My R8000 does not recognize that anything is plugged into it. CAT 5 and 6 cables are recognized and my computer recognizes the CAT 7 cable just fine. Everything I've read online suggests CAT 7 cables should be compatible with even older CAT 5 ports. Suggestions?

Don't quote me. I've got a mate who lays internet lines. And he's had cable go faulty even if one of the wires inside inside that older cat gens dont use.

Haha! You have been quoted by the quotemaster! Take that!

 

Anyway, @ankybone Cat7 cables are actually not an FCC standard. They do not have to fit within any specification. Cat5, 5e, 6, and 6a cables have to fit within spec. There is no reason you need to use cat7. You only have gigabit. It's the same thing with hdmi cables. Silver conductors does not 'improve' quality. It's all digital. As long as the 1s and 0s can get from source to destination, there is no real difference. (This is way over simplified, but still applies.)

Check the speed that your computer links at when connecting to the modem using the Cat7 line. If it says "100Mb" and/or "Half Duplex" then at least 1 of the wires in the cable is not connected, and your router may be less flexible about negotiating a link than the computer.

While not recognized by the FCC, there is an international standard for Cat7 cables, and they do actually make a difference - when trying to link 10Gb at around/over 100m. That being said, many/most "Cat7" cables are actually cheap crap, barely capable of passing Cat5e ratings.
