I have a Linksys WRT160N v3 wireless router and I find that even when my home network is showing 5 bars, I can't always connect when I'm using my laptop in another room. I happen to have a D-Link ANT24-0700 antenna which I believe can be used to transmit as well as receive. If so, how would I connect it to my router? I can't see anything on the router that would allow that but maybe I'm missing something.
If I can't make a direct physical connection with the router, is there perhaps a PCI card that I could put in my computer, designed for the purpose of taking the signal coming in via ethernet and amplifying it for transmission to other wireless-enabled devices such as my laptop?
