I have an older model computer and I need the network adapter card to connect to wifi I actually have one but its an older model Linksys wireless G and its great just doesn't get very good range.

I was using PCMCIA "Texas Instruments PCI - 4510 card bus"; it was working very well, but when I move to a big house, it couldn't work for me.  First I went to electronic store and they told me to buy an antena; I bought and the signal strength were low.  I then went to factorydirect and I found Linksys Wireless-N and bought it.  Since I bought it, I have never experience any problems.

If you are willing to buy, you can buy it from any electronic store. It is also cheaper to buy it from http://www.factorydirect.ca in person if you live close to them; otherwise, they will charge you for shipping.

Hi, and welcome to IMshopping! Some of the newest Network Adapter Cards are for the Wireless N Networks. Depending on whether you have a laptop or not, you could chose between a USB plug n play, plug in ones that go into your Express Card Slot or one that you can directly install into your desktop computer. I have found several choices for you to check out. I hope these help and happy shopping!
