Greetings, Before I continue to struggle with this, I'm wondering if someone can confirm the viability of the following scenario: N wired to AE wds'd to ABS wired to switch wired to other PCs N = existing ethernet network AE = Airport Express config'd thru WDS as a 'base station', though not distributing IPs etc (that is handled through N) ABS = Airport Base Station config'd thru WDS as a 'Remote base station' The problem is, when I connect an Airport client computer to the network (by choosing the AE) I cannot see the PCs at the end of the chain. I'm testing this connectivity through pinging. Am I missing something? Is it possible that an AE cannot be a base station? Many thanks in advance for any suggestions/tips!
