Go get any of the Amazon Basics Ethernet cables and be done with it. You will find folk fretting over this but at this speed and distances up to 100 meters Cat 5 up to whatever the current Cat is will do fine.
Your choice to extend this worry.
So I want to connect my TiVo Premier to my home network via ethernet cable rather than wireless. I'm admittedly a little clueless on cable types, so would anyone recommend a Category 5e, Category 6, or Category 7 ethernet cable? (or any I didn't list). I'd be running about 25 feet of cable from my MI424WR Rev I, Verizon Fios router (25/25mbps). Will eventually be connecting a TiVo Stream as well. Thanks for any tips!
