Atheros 8121 ethernet controller says gigabit on the box (Asus P5Q Barnaby 12/28/2008 5:49:01 AM It is advertised as gigabt=1000 megabits but only shows up as 100 megabits. What gives ? I have the latest driver loaded on Windows XP Home Service Pack 3. -- Barnaby

Some cheap cables only have four wires inside the cable (and 8 pin connectors). It won't autodetect GbE unless four pairs of wires are present and working. (I had that problem on my older computer, where one of the contacts in the Ethernet connector wasn't making good connections. I had an eight wire cable, but it detected as 100BT. Inserting and removing the connector five times, cleaned it and it started working.) Paul

If the device at the other end of the cable is 100BT, then both ends run 100BT and no more. For a GbE link, both ends need a GbE chip, and you need a cable with eight wires. There is no reason for a cable modem or ADSL modem, to have a GbE interface. More likely to be 10/100BT. For cable types, start here. There are links near the bottom of the page, for the other standards. For a short patch cord, I wouldn't expect the various cable standards to make a difference. http://en.wikipedia.org/wiki/Category_5_cable Paul > > > "Paul" wrote: > >> Barnaby wrote: >>> It is advertised as gigabt=1000 megabits but only shows up as 100 megabits. >>> What gives ?

Re: Atheros 8121 ethernet controller says gigabit on the box (Asus Barnaby 12/30/2008 6:01:01 PM Thanks , that answers it. My cable modem must support 100 megabit. The only time a Gigabit connection is an advantage I heard is if you are doing a file transfer like over wifi assuming the device supports it. -- Barnaby "Paul" wrote: [Quoted Text] > Barnaby wrote: > > -- The cable says Cat 5 on it and says it has four pairs .
