Re: Upgrading CAT-5 to CAT-6
Howdy, Cat6 is the spec for gigabit speeds. Cat5 cables frequently work fine at gigabit speeds, but not always. So, if you are already getting gigabit speeds, then no cable upgrades are needed. Most routers have only 10/100 switches built in. So, I'd get a gigabit switch. Connect one of the LAN ports of the router to the gigabit switch and then all of your local machines to the switch. Then, transfer speed should go up between any machines with gigabit ethernet. For me, transfer speeds between my desktop and my NAS really went up when I made a similar change.

Nearly all 'Cat5' cables sold today are Cat5e, which are good for anything oyu can get in a home network, which is gigabit ethernet. Also, this really only counts on very long runs, 75-100 m or more. You can crank 100 megabit over a cat 3 cable if it's only a 15' run. Anything labeled Cat5 is going to be good for a home network up to gigabit. Note you need a gigabit router or switch for this to work.

Upgrading CAT-5 to CAT-6
Just wanting to check that my understanding is correct. When I upgrade from CAT-5 to CAT-6, I can upgrade sections of my LAN one step at a time, and have higher speeds on any 100% CAT-6 paths without being downgraded to CAT-5. 3 computers, 2 NAS drives, 1 router. Computer A <-> Router = CAT-6 Computer B/C <-> Router = CAT-5 NAS 1 <-> Router = CAT-6 NAS 2 <-> Router = CAT-5 Computer A <-> NAS 1 has higher transfers Computer A <-> NAS 2 has lower transfers Computers B/C <-> NAS 1 = lower transfers Computers B/C <-> NAS 2 = lower transfers Now I'm pretty certain the router plays a role in speeds so what specs should I be looking at to see if the router can handle CAT-6 speeds?
