RE: NIC speed |

 LtKer Semper No you will not get gigabit speeds out of your LAN unless all your computers send and recieve everything via memory instead of a hard drive. No hard drive today is cable of sending and recieving data at gigabit speeds. Most IDE drives will only give a maximum of about 20Mbps with the hard drive working at maximum efficiency. For your home LAN I wouldn't waist the extra money on gigabit ethernet cards and switch. You will not see a big difference between 100Mbps and 1Gbps. The only thing that you would see a difference in is that 10/100 SOHO switches only have a 100Mbps backplane. That means if you have 10 computers on a switch connecting at 100Mbps / full duplex you and actively competing for bandwidth you will only see 10Mbps of bandwidth to the individual computers because the backplane of the switch can only switch packets at 100Mbps. Same thing with a SOHO gigabit switch. 10 computers at 1Gbps actively competing for bandwidth will only see a maximum of 100Mbps *theoretically*, you still have to remember that your hard drive won't read and write data the fast. wireless is a convenience. You can carry your laptop anywhere around the house. You don't have to run wires all over the place. The downside to wireless is that it's like a hub. The more wireless clients you have on a wireless access point the slower your connection will be. Why, because wireless is shared media. 10 computers at 11Mbps wireless speeds = a little over 1Mbps per computer, then you have to think of interference. 2.4Ghhz wireless phones, microwaves, neighbors running 2.4Ghz wireless access points can all contribute to radio wave interference hence a slower connection. Don't get me wrong though. :) I still love wireless technologies. :) Another tip to think about that will optimize the speed of you home LAN is duplex settings. most computers by default operate at half duplex. This means that the computer can only send and receive data in one direction at a time. You will need to manually configure the nic cards to operate at full duplex. This means that your computer can send and receive data symmetrically. I hope this helps. :) Semper On 2003-06-26 12:07:30, Darkwater 685 wrote >Im looking at setting up a LAN and when I was looking at NICs i found that you can buy a Gigabit Ethernet NIC, but the wireless card i was looking at only claimed 11Mbit speed. Is the ethernet NIC really going to give me gigabit transfers? If so, do I need to do anything special or is CAT-5 cable and a Switch going to get the Gigabit speed? > >Thanks, --Semper Replies:
