Hi have two Deco X60 connected to an LTE router via 1000mbps TP-Link Powerline.  The "master" deco is connected to a powerline adapter, and the LTE router in the attic/loft is connected via powerline.  The "slave" deco is upstairs.  It has been setup this way for about 8 weeks with no issues whatsoever - it massively improved things in the house in general.

I have a problem which started a few days ago where my Playstation 5 connects to my mesh wifi but cannot detect an Internet connection.  I also have a Windows 10 Pro laptop exhibiting the same behaviour.  Connected but no internet.  My Samsung TV (AU7000, so recent) is the same - no Internet.  Yet I write this post from my Windows 11 Home laptop, connected to the same deco wifi with zero internet issues.  I am using multiple browsers, OneDrive, and a Citirx client to talk to a work VDI.  However Zwift, a local app that uses the system web viewer control, isn't working on my Win11 laptop.

Can anyone offer some advice.  I've rebooted the router and the deco system and the PS and laptop.  I fear it's something silly like when my kids phones first connected they had to "authenticate" which was just some checkbox.  However I have removed the PS5, laptop, and TV from parental controls (even though they were setup as family members with no restrictions).

I don't have the premium homeshield only the free/basic tier.

Thanks
