So, I have an AirPort Extreme named AirPort North, and an AirPort Express named AirPort South. APN (AirPort North) is connected to the modem via Ethernet, and APS is acting as a WDS. I was having some issues earlier, and I was trying to expand their coverage, but I reverted back, but now, APS will show green, and it will show up in the AirPort Utility, but it won't show up in the list in the menu bar or in the task bar for the windows users. I've reset it, but I can't seem to get it working. Any help? Thanks!
