Hi, I'm brand new here and I don't have tons of computer knowledge although I am learning....I hope! We bought a campground last year and were offering a wifi hot spot located near the camp office. It was actually done by accident because we live in the same building and have our own home network of 3 computers. We have a Linksys WRT54G router and a cable modem. So the campers were hopping on our wireless. I had some problems over the winter with someone using my credit card online. I was advised to maybe try getting another router and a hub/switch and basically to hook that hub/switch to the cable modem and then hook both routers to that and to have one of the routers be secured (WPA) and the other unsecured for the campers to use as a wifi hotspot. I also bought a Linksys range expander which I haven't set up yet. If this configuration with 2 routers on the same cable modem will work, I will set up the range expander to the unsecured router. I emailed linksys to ask them if this whole configuration was possible and the answer I received was basically not very straightforward but they made it sound like it couldn't be done. So now I'm asking you if it can be done the way I said or if there's another way I can offer an unsecured hot spot without compromising my own home network and security and without costing me a fortune. Hope someone can help. Thanks.
