Real speeds of fast routers and NICs

  JonJ 11:25 AM 04 Mar 12

The maximum speeds of Wireless-n devices are typically 150Mbps or 300Mbps, but in real world situations speeds rarely come close to these. So my question is: does it usually make any difference whether you have a 150Mbps device or a 300Mbps device? To put it another way: if you are achieving, say, 50Mbps with using 150Mbps devices, would you achieve a higher speed (or double the speed) with 300Mbps devices?

The limiting factor on some though perhaps not new PC's is the speed of the network card or chip, these were typically 100Mb, as my internet connection is over 100Mb I installed a 1000Mb card - There are perhaps other bottlenecks though. - If you have a 100Mb network card you are never going to top that.

As regards wireless few if any people ever see the theoretical limits as walls & other obstructions soon slow things down.

Also you would be limited by your broadband speed if surfing the web. My new PC will go at over 100MB but my older one struggles at more than 75MB on the same router.

I should say that's with a wired connection - wireless is quite a bit slower.
