    I had to steal a internet connection and the bad part was that i had only access to the wireless network in the bathroom. SO browsing while taking a shit is the only option so i had to extend the range someway. I had a WRT54G and WAP11 lying around in my house. So this is what I did..

    I followed instruction here to mod my linksys WRT54G to act as a client and connect to the neighbor. Thanks god he hasn't enable security.

    Then.. I connected the WAP11 to the switch on WRT54G and holy crap.. I have wirelesss connection in my house. UNTIL the freebies end.

    I think instead of using the WAP11 to connect i can somehow configure the WRT54G to do both of the job. But this did the thing for now.. I am happy.

    It's the one mentioned on the link. Alchemy something. I am not too up to date on the linksys hacks .. but i think it's the latest alchemy hack.

    cool thx. you should try dd-wrt, if you think that alchemy is good.

    I have a wrt54G connected to a WAP11 and it works well. If you ever decide to upgrage the WAP11 to another WRT54g, remember to turn off the DHCP server. It may work for a while but shortly you will get machines assigned addresses that are not in the right network.

    I know this sounds obvious but it took me a while to figure out why the WAP11 always worked and the WRT54G would work for a while and the quit.

    I am using DD-WRT on the WRT54G and like it a lot. I tried several other version and DD-WRT was the only one I could get to work right.

    I have now installed a cheap hub in front of the WAP11 so that I can hook up both wired and wireless computers.

    Thanks for the heads up.. BTW... what u mean by IP addresss of wierd networks.. Will the DHCP server give u any IP address unless the ones in the range u have asked it to. It's strange.. But i believe.. Would watch out next time..


    :) hate me if u hate the stealers.. But I am loving it not for the money I am saving but the thing is that i got it to work. I am a geek.

    My last post needs a little more explaining. I have an antenna connected to a WRT54G running DD-WRT. That is outside on a post. I have setup power over ethernet so the extra 4 wires in the ethernet cable bring the 12 volts from the house out to a box near the router. The box contains a RJ45 punch down so I split the power back out to a connector that fits into the back of the WRT54G. If you are interested in how this is done, Google power over ethernet and you will find some nice plans. DHCP is enabled on this WRT54G.

    On the other end I have a similar box that has the 12 volt transformer plugged into it and a RJ45 cable coming out. The RJ45 goes to the hub and then a cable goes from the hub to the WAP11.

    My original plan was to use a second WRT54G instead of the WAP 11 and hub.. I planned to connect the cable from outside to the one of the switch ports on the WRT54G. It would work for a while but then stop. After much playing around I found that the second WRT54G was trying to assign IP address also because the DHCP server was enabled. Things would work until the power was shut of and then some machines would come back up with an IP address in the wrong range. The second WRT54G had its DHCP server enabled and was giving out bad IP addresses. Shutting off the DHCP server on the inside WRT54G solved the problem.

    Adding the hub in front of the WAP11 allows me to plug in a computer and configure the WRT54G which is outside on a pole. You cannot do that through the wireless because you are on a different subnet. It also was the hub that gave me the clue that the second WRT54G was causing the DHCP problems because everything that was plugged into the hub seemed to get the correct IP address. The wireless was what did not work so I did some checking and found the bad IP address problem.

    I saw the following news article on MSN yesterday, and couldn't help but laugh when I read this thread. It's none of my business if you're stealing internet or not; I really don't care. lol Anyways, a guy was arrested for using someone else's wireless network to use their internet connection, so be careful at least.

    this is the first ever conviction of someone using someone elses internet. if i was the guy that was being charged i would say "i though it was a free hotspot like they have @ starbucks" :D
