Hello!
I got this new WiFi device today, it emits a fairly loud buzz/hum so i opened it to have a look were to put some nail varnish in case the offending part is accessible.
I expexted a tin can to cover most of the PCB but i was a bit surprised when i found this:

This can not be right, right?
I thougth RF stuff has to be shieldet for various reasons.
Greetings,
Peter
