Hey, I am going to e orderrig 2 Cat6 cables for my modem to go to my router and for my router to go to my computer. I have been using some old Ethernet cable, probably a Cat5, that I found in my garage to connect my router to my comp. The speeds are terrible; ~1mb/s. My router supports gigabit speeds, and my modem is getting supplied by standard cable. I am paying for 15mb/s, so using a Cat6 cable, what speeds should I be expecting? Is Cat6a worth the extra money? I may know a lot about computers, but I am not well versed with networking. Cheers!
