I have a macbook pro and version 10.5.6 of leopard. My household used to have att internet with a router they provided. It worked amazing, i got wireless internet in my room and throughout the house. So out of the blue for no reason my mom gets comcast and we have to get a new router. We end up getting a linksys router and it says that any computer that is ging to be connected to it needs to insert the install disk into it and set it up. Well, the install disk ends up messing up my mac to the point where the airport is off and wont turn on no matter what. It messed up all my network settings. I couldnt connect to the wireless or ethernet. I found a site online that somewhat helped me. I forgot what i did but now i can actually use the wireless. But since the disk messed with my computer settings i cant pick up wireless unless directly next to the router which is set to maximum on distance it reaches. My brother has a pc and it connects to the wireless wherever in the house. Im starting to get really frustrated and am pretty dumb when it comes to anything more complex with my mac so i have no idea what to do. So now when i go into my network it has airport and all that but i cant use ethernet, it wont read that its connected to my laptop. So basically wireless is crap and ethernet is done with. please help
