    I know that this question has probably been asked before, but I just can't seem to find any good information on this subject.

    Does anyone have any clue is it would work to change out the linksys mini pci wireless card for say something a little more powerfull.

    I'd like to run DD-WRT with maybe something like the following card.

    http://www.demarctech.com/products/...-rwu-600mw-atheros-802.11g-mini-pci-card.html

    There are linux drivers for the above card.

    What would it take to get this working. Is it simple or not worth the effort.

    I already have the router and plan on using it to establish a long distance connection at around 2.33km. I have full line of site with NO obstructions of the the fresnel zone. I'd like something with a higher power and sensitivity than the linksys card in this router has.

    At 2.3Km you card is the least of your concerns. You will need to have the proper antenna in place at both ends to even consider this.

    Should be good then, if i was in your place i would test it as is. If you need to make changes i.e. incur other costs at that point then so be it But why spend the money if there is no need. But back to your initial question, i know there are lots of posts out there, have not seen many on this site but i know there are many out there on what cards work the best. However all that i have seen personally are for users wanting to do things locally that the inbuilt card does not offer. I dont see that being the case in your instance.

    I agree with the above. Anyway, you can use only one directional antenna not two. But a connection of 3 Km could be reached with default antenna on router (2 db) one one end and a USB stick in a can on the other end. I experimented that, long before reaching and reading linksysinfo.org or this site (with many examples of antennas-spanish language). What I've experimented looks exactly like "Scenario 2: Outdoor USB Wireless solution (distance < 3km)": so no need for high gain card&two directional high gain directional antennas.

    Yeah I'm pretty sure that just one antenna would work. But for added security and stronger signal strength I plan on using a 24dBi dish on both ends. I'll be installing the router in a weatherproof outdoor box and running POE. I'll update pictures and diagrams later. I knew that the stock card would work but I'd still like to play with a different wireless card just for the hell of it. What would you guys suggest I set the transmit power to on both WRT54G's. I'm currently running 60mW. I'm thinking thats plenty when considering the antenna's I'm using.

    aligning those 2 grids are going to be a major b*tch, especially over 2km. I hope you know a decent amount about aiming these and such, which it looks like you may...what with mentioning the fresnel zone and all. :) Might as well run at 84mw, since that's the highest you can run without putting a heatsink on the radio. Good luck...
