Hello orez, and welcome back to the community!
It is indeed unusual, especially as you are working with the WiFi due to the ethernet port not working (was this a relatively recent development, or has the port not been working since you received the Shake?).
Could you please download the logs from the Shake (if needed, instructions are here: Please read before posting!) and attach them to your reply?
Could you also attach a couple of screenshots of “rs.local/”? One of its main page and one of the Settings page would be perfect.
Thank you.
