I have a Dell laptop with a built-in 802.11g card which I use for accessing WiFi Hotspots while on the road. I want to increase the range of the card by adding an external antenna which will mount on the roof of my travel trailer. The question is, how do I attach the antenna to the laptop. One suggestion I've read is to add a Zoomair Model 4103 PCMCIA card, which has a removable antenna, and use it in place of the internal card with the outside antenna attached to it. Another is to use a Linksys WET11 bridge, attach the outside antenna to it and attach it to the laptop with an Ethernet cable. The third is to purchase a Linksys WRT54g access point with Sveasoft firmware and use it in client mode. I'm totally new to wireless and much of what I've written, I'm not sure I understand. Any suggestions on how to proceed will be greatly appreciated.
