-- Posted by Falling Star at 5:18 am on Nov. 7, 2008 I'm currently running XP with a modem. But have bought a new computer with Vista which is incompatible. I've heard I need to buy an ethernet cable to make it work. 1. If I buy one, do I just plug it into my computer and modem? Where the hell do they go? 2. Around howmuch are they? Generally. 3. Are they reliable? -- Posted by Jadien at 5:19 am on Nov. 7, 2008 Why would you a buy a computer that wasn't compatible with your modem? -- Posted by Dass at 5:19 am on Nov. 7, 2008 all you need to know is the length and if you have an available port on your computer -- Posted by rawrr at 5:21 am on Nov. 7, 2008 Yes, they work (obviously) not all that expensive, maybe 15 bucks and yes they are reliable. -- Posted by UndergroundKing at 5:33 am on Nov. 7, 2008 Depends how long of a cord you need... A 6ft is only like $4 max.  A 50 ft is $20 max. As far as reliability.... Meh, they are cheap ass cords.  But if you treat them with some level of decency it should last. -- Posted by espresso8097 at 1:48 pm on Nov. 7, 2008 Is this a dial-up, cable, or DSL modem? If possible post the brand and model of modem.  Just because it is not marked as being compatible does not mean there are not ways to make it.   -- Posted by allsmiles at 2:59 pm on Nov. 7, 2008 You're going to need a NIC for an ethernet cable to plug in. Ethernet does not interface with a modem directly. -- Posted by YeahBoii at 5:47 pm on Nov. 10, 2008 $6.99 for a 50ft one. http://www.newegg.com/Product/Product.aspx?Item=N82E16812105309
