All of a sudden yesterday multiple devices in my home failed to obtain an IP address (iPhone 11, Samsung Note 10, Google Pixel book, iMac, Google Home, Google Nest Mini) but one device MacBook Pro is still able to connect?!?
I have a SuperHub 2ac.
I can't hard wire into the SuperHub using a patch cord either anymore. Which always normally works?
I connected wirelessly to it via the one device that still works, the MacBook Pro.
I reduce the DHCP lease time to 10mins, turned on and off, reset it via the pin hole and there is not change. Devices are still unable to obtain an IP address.
Re: Some devices now unable to obtain an IP address
I investigated a similar problem for a neighbour recently (albeit with Hub3). Turned out to be an address conflict caused by an errant piece of Apple hardware. After it was removed, everything worked OK. I'd suggest switching every user off then re-adding them one at a time to see if there is a particular device causing trouble.
