CALLING NETWORK GURUS - PLEASE HELP A BROTHER OUT! Bounty available for any hero that suggests something leading to a fix!

Last week my home network suddenly started showing certain devices as 'connected / no internet access'. It seems to only be affecting mobile phones (iPhone and Androids), tablets and the TV. My Linux machine and Macbook are not being affected whatsoever, nor are any ethernet devices like my nodes and security cameras.

When these devices show the error, there is nothing apparent that causes it. There is also nothing apparent that allows them to connect again and function normally (for a short time at least).

Today my ISP sent me a new router, but that did not fix the issue. There has been no devices added or removed from the network in recent weeks that coincide with the problem starting. Finally, I tried setting a static IP on the router for one of the problem devices, but that made no difference.

Can you install a terminal app one of the Android devices and see if you can ping out to the internet (8.8.8.8 or similar). This sounds like DNS is getting messed with.

Do you do any whitelisting of MAC addresses? The mobile devices change their MAC addresses often.

Very likely a DNS issue.

Yeah I can try on my pixel tomorrow morning. I've not touched any MAC related settings on any affected devices or at the router level.

There is now a full Linux terminal on Pixel devices. I highly recommend it!
