M5 mesh network, I Updated the firmware to 1.8.5 20250612 rel 44225.

Since the update the devices all access the M5 deco units but some (but not all) can't now "see" the internet.  So my SkyQ box has connection with the network but no internet access.  The Sonos worked fine but since resetting it to fix a different problem, it cannot now access the internet to allow Alexa voice control.

connecting directly to the router everything works.

Where do I start?  The iPad I'm typing on is connected to the same M5 but has full internet access, so it's not every device. 

thanks
