Can't get Airport Express A1088 to work with A1264
Hi,
My modem and office are at opposite ends of my home, so I've been using 2 x Airport Express base stations (both A1088) to connect to the internet. One is plugged into the modem via an Ethernet cable, the other is set up in a hallway to extend the range (I just lose the signal if I only use one AX). On Sunday, one A1088 "died" so I bought an A1264 to replace it. I've tried to set them up as a network (following WDS instructions on this site, etc), but no joy. Airport Utilities just won't "see" them. Any tips for set-up or ideas where I might be going wrong? Is there a step-by-step guide anyone can direct me to? Or would I be better off just buying a second A1264?
Thanks in advance for your help.
