My iMac G5 is no longer correctly sharing my dial-up internet connection. We use a 12" PB G4, an iBook G3, and a MacBook in the house via Airport, and all network services work, but the internet connection is not functioning properly on any computers except the iMac. I think that the iMac is sharing the connection, but for some reason is just letting a little bit through. For instance, if there are no internet-using applications running on the iMac and there is only one computer trying to access the internet and it is sitting right next to the iMac, it can take 10-12 minutes to load a page, if it loads at all. In all fairness, my PowerBook does this with two other connections, but only on a specific ISP in our area. At home we do not use the same ISP. The routers used in these two locations are of different brands and one location has regularly switched brands due to malfunctions. Any ideas as to why the connections are so slow?
