Will a D-Link Xtreme N Provide fast connections when connected to Linksys WRT54G?

Question

Hi everyone, I'm not new to wireless networking however I am looking to buy a product that will allow me to get an even higher connection speed. My current maximum is 54 mbps, and I want at least 100 mbps and I recently discovered some products that can deliver some higher connection speeds but I was wondering if the high speed is a combination of my pci card and my router. If i buy a newer, better pci card then will I have to buy a new router to experience the fastest connection speeds?
I currently have a Linksys WRT54G router, so if I put the new PCI card in my computer and connected to the wireless network would I experience faster connection speeds or would I have to buy a new router as well?
Thank you and here's the link to the new PCI card I want:

Answer 1

You are always limited by the slowest link in your chain, but with that card you will gain the benefit of mimo antenna structure. The truth is your weakest link is most likely your internet connection. so for online gaming or anything that requires getting out of the building, your internal 54 mbps system is already faster than you can take advantage of. Internally you need to speed everything up to achieve the higher speeds.

Answer 2

The router you have is capable of 54 Millions bits per second. That is equivalent to a 6.8M dsl line. If you get the N type of device it will automatically downgrade to the G standard. Technically, it is an unneccessary added expense. The G device for the computer should work well if you do not have interference from outside sources. I have always had good luck with the wireless/USB devices. It will allow placement outside the back of the computer with the cable.
