I've recently purchased and installed a 3-unit Deco M5 mesh as the current Fritz!box as supplied by our internet provider doesn't cover the whole house.

Since installing, my work laptop (behind a work-provided VPN) thinks it's based in Guangzhou, China.  If I disconnect the mesh, the issue resolves.

Similarly, using the Google search widget on my phone results in a "too many requests detected" issue from Google and refuses to load any results. This doesn't prevent search suggestions from loading while typing.

If I turn off WiFi and use the network connection, all works perfectly again.

I can't replicate the issue on my android tablet... (Older android version)

Any suggestions as to what could cause the issue?
