I have a question that I'm hoping someone can help me with. My Airport Extreme Base Station is connected to the internet via a DSL modem in my back office where I also have my eMac. Because the AEXBS doesn't have enough range to reach all the way into my house where I have an iBook, I bought an Airport Express to basically function as a network extender. But while my iBook has no trouble connecting to the network, it freqently cannot connect to the internet. Any ideas why? Thanks.
