rj11 cat5
I dislike AT&T internet at home. Oddly enough, they use a Cat5 cable with an RJ11 port. The length is only about 6 feet, but I need a 25-foot cable. Since I’m rearranging furniture, I require a longer one. Where can I purchase a Cat 6 RJ11 25-foot cable?
RJ11 is designed for mobile devices. You won't find cat5 or cat6 cables with RJ11 connectors—this explains why you don’t see cat6 cables paired with RJ11 jacks. Ethernet connections require RJ45 ports. The cat5 cable works well for 100 Mbps, and even shorter runs suffice for 1 Gbps. Cat5e is intended for 1 Gbps speeds... and it seems unlikely you’ll find cat5 Ethernet cables available in 2019. It’s likely the cables you see are specifically for phones.
Many contractors today primarily rely on Cat5e for Ethernet and phone connections. It's more economical to purchase cables in bulk rather than carrying multiple types. I believe Cat3 (for phone) has largely disappeared. You're correct—networking cable can be used for phones, but you only need about half the wires. As @WereCatf mentioned, shielded cabling is necessary when dealing with interference. Or simply avoid running cables near electrical sources.
