The router I have is a model WRT54G3G-ST ( http://support.linksys.com/en-us/support/routers/WRT54G3G-ST ) It allows for a pcmia card to be inserted into the top of the router. I am trying to find the correct firmwear on the page http://tomato.groov.pl/download/K24/ I am not sure which firmware to use for this router. If I get it wrong it wont work. Because it has this special feature I need to make sure to pick the exact firmware. The card get the signal through the pcmia card and broadcasts it via wifi. Its a card that has unlimited internet for about 50$ a month (grandfathered) but only at 1.33 mb speed. Its feeding a "compound" where my mother in law lives. There are a few people that use the internet from it. A few people torrents relentlessly and uses a lions share of the internet. I do not mind torrenting unless it blocks nana from using the internet. My plan is to put the tomato firmware on it. Then I can put all the mac addresses on the router that use the internet and manage them. With tomato I can limit each mac address. I can also limit torrenting in the QOS section. That is my plan for keeping family harmony and allowing my in laws (nana and poppa) to browse facebook unencumbered by unpaid torrenting. If you have any thoughts I would like to know. Trying to set it up today.
