I have been having this problem for around the past 4 months. Every day, my WiFi connection drops on certain devices but continues to work on others. The devices can be phone or a laptop, it picks at random. The devices show that they are connected to the WiFi, but they cannot connect to the internet. Bringing the device closer to the hub makes not difference. Disconnecting and reconnecting the device will temporarily give the device internet for a few minutes, but then the issue returns.
I have replaced my Hub 3.0 with a replacement Hub 3.0 thinking that the issue was with the hub, however the issue continues. Rebooting the hub seems to be the only temporary solution as the issue doesn't usually return for around 12 hours. I cannot stand having to reboot my hub daily for the past 4 months to get a WiFi connection on all devices. I have called support but they have been of no use as they say everything seems fine from where they are. What could be causing this issue and how can it be fixed?
