I am new to building wired & wilreless network. I need build wired and/or wireless network in my motel. I have three buildings. Office buidling has the dsl service. 50 feet from the officebulding is located 2 story 140 feet long concrete block bulding with chaseway in the middle. If I really work hard I can probaly hard wire this two building together(If possible I do not want to do it). 3rd bulding is located about 100ft away from 2 story building and there is no way to hard wire this buidling(but may be hard wire from office building-but it is about 150 feet away with driveway in the middle. I just bought linksys WRT54GX4 router installed with my 2wire dsl modem. After moving my router, I got covered my office building, and 1/4 of my 2 story building. Somehow I need to extend wireless access for my coustomer to the all the building. Cost is concern, but want to build reliable network. Since I have not done this kind of work before, I want to be able to do it my self, so I can figure out when it stop working. My option are I could buy all the router , access points, or range extender that I will need but I want my network work reliable and fast. thank you in advance for any help..
