I've searched the archives for this, but couldn't quite find exactly what I was looking for: I have a Linksys WRT54G that used to be wired inline from the cable to my iMacG5. Wirelessly, I was also able to use a Dell desktop elsewhere in the house using a Linksys 54G adapter for it. Except for excruciatingly slow speed on the Dell, the wireless functioned okay. For convenience sake, I decided to swap places with the WRT54G, and hooked it up directly to the Dell. Then, I bought an Airport Extreme card and installed it in the iMac, and installed the software. The Dell works much better now, but for whatever reason, I can't get the iMac to see the network - though it WILL (I guess) connect directly to the Dell (status says: computer to computer). I've played around with the configs on the router several times, but can't seem to get the iMac on the internet. What am I doing wrong here?
