|Thanks for your responses and the link discussing differences between cables. Considering FIOS though, is Cat6 better than 5e?|
The simple answer to this question is no. They are essentially the same as far as the bandwidth you'll be using at home goes.
I recently received a circular from Verizon stating FIOS can do 5 to 15 Mbps. I think I answered my own question; if cat5e can do 10BaseT and 100BaseT that's way enough, right?
Cat5e and Cat6 are both capable of 10, 100, and 1000 Mbps. The main difference (as stated in the article wanderer linked for you) is that Cat6 is certified for 1000 Mbps. Cat5e can, and does, do 1000 Mbps.
