Have a HG659, running the latest firmware supplied by BigPipe ~12 months old.

Have an interesting intermittment issue with what seems to be DHCP leases. Occurred in the last 15mins with my iphone 8 being unable to access the internet via wifi (4G Spark fine). At the same time my iphone 7 and ipad could still access the internet. All three devices running 12.1.2.

I looked at the wifi information in iOS for the iphone 8 and all the dhcp information was missing, the iphone was showing as connected to the wifi router, (status bar), but wouldnt look up the router address. I then logged in to the router on the ipad, the DHCP lease was -190 hours.

Turned the guest network feature off and the iphone is now working. Interestingly the ipad then forgot the network key. Have checked the logs and can’t see anything...

Couple of thoughts: could it be the number of reserved devices (28), lease duration is one week not sure if this influences the situation, uptime currently is 7 days.

Two screenshots below (didnt think to grab one of the router).

Any ideas welcome
