Our home is currently wired with Cat5e throughout and has been fine for the 45Mbps service we have from AT&T. We are now switching to Spectrum's Gigabit (well, 940Mbps) service and I'm wondering if our Cat5e will be sufficient. We have multiple AppleTV's, including 2 of the 4K versions, several computers (iMac & pc) that are hardwired via ethernet, and two Apple AirPort Extreme wireless routers. So far I've heard conflicting information. Some of the things I've read say we should be fine with Cat5e, while my son's techie friend insists we need Cat6a or even Cat7. I'm prepared to rewire the house if necessary, but don't want to do so if we won't really see a difference.
