We have an AirPort Extreme 6th generation in the office. It's providing 5 GHz and 2.4 GHz wireless networks, with different names:
AirPort Utility: Wireless tab:
AirPort Utility: Wireless options:
Sometimes, when a device is on Brains 5GHz, it can't communicate with other devices on the network, but it's able to connect to the internet with no problems.
It doesn't happen all the times, but it happens pretty frequently. Once it's begun, the only resolution is to switch my devices to the 2.4 GHz network, at the cost of much worse wireless performance.
When I say my devices "can't communicate with other devices on the network", here's what I mean:
- Can't print from MBP or iPad (airprint) to wired printer. Printer status says the printer is "not found".
- Can't ssh/screen share to coworkers' computers.
- Can't reach my dev web server on my computer from an iPhone/iPad (and other mobile devices).
- Can't mirror to Apple TV xe2x80x94xc2xa0doesn't even show up on the Airplay device list.
If both devices are on the 2.4 GHz network, there are no problems. If even one of them is on 5 GHz and the AirPort is misbehaving, we can't communicate with them.
The behaviour makes me wonder if the AirPort is isolating clients from each other somehow, but I've gone through the settings and updated the firmware, and still have problems.
Is there something I can change in my setup to resolve these problems?
