Have recently gone back to using the HH5 with Infinity service, but finding that many of my iOS devices will *sometimes* fail to detect the 5ghz network. I've intentionally named the 2.4ghz and 5ghz networks differently so that I can control which devices connect to which. This broadly works fine, but both an iPad Mini 2 and an iPhone 6+ will at random refuse to see the 5ghz network. If I restart the Home Hub the network again appears.
I've already disabled the 'smart setup' option based on another post in the community, and I've manually adjusted the DHCP lease time to the maximum (21 days) hoping that it might be a problem with DHCP addresses renewing. Sadly that has made no difference. Also both 2.4ghz and 5ghz networks are set to 'smart' channel selection. I can connect to both from a laptop without issue, and Wifi Explorer can see both networks with approx 75% and 45% signal strength, respectively.
Has anyone else experienced similar and/or know of any settings that might address this?
For reference, my HH reports the following:
|2. Serial number:||+068343+NQ34653453|
|3. Firmware version:||Software version 18.104.22.168.83.8.204 (Type A) Last updated 03/04/15|
|4. Board version:||BT Hub 5A|
The range at 5GHz is much shorter, so maybe that is the issue?
Possibly, though disproven by the fact that both devices have been connected to the 5ghz network and tested at full bandwidth from the same location previously, and also another device (laptop) connects to the 5ghz network without issue at the time the iOS devices don't detect the network.
When the issue occurs, standing directly in front of the router with no obstructions the 5ghz network is not visible.
