The wiki talks about Ethernet standards - Cat 6 as current, Cat 5 as only 10/100 Mbps (not true) and Cat 7 as the "future" standard.
Per Wikipedia, Cat7 is not an IEEE standard (https://en.wikipedia.org/wiki/ISO/IEC_11801#CAT7), and uses proprietary connectors that, while may resemble RJ-45, are not compatible with most equipment using RJ-45/8P8C connectors.
Additionally, Cat 5e can run 1 Gbps speeds just fine, and is the most commonly found cable in most houses and most situations. It can even run multi-gig, at short distances, though this isn't per-spec.
My suggestion is to remove Cat 7 from the wiki, include a mention of 5e and perhaps state how a user might identify the type of cable they have, maximum transmission distances/speeds, etc. A simple table would do the job here - I'm happy to provide one if requested. Thanks!
