Where is the WiFi on this model? Windows couldn’t see it when doing initial setup
It should have, per the specs:
Wireless: USB WiFi dongle
Check the box for it? If you don’t find it, you can reach out to 203 trading (warranty link on features) and they should be able to send you one.
If all else fails, Woot Customer Service. From a browser, use the Woot Customer Service form. In the Woot App, choose Account from the bottom navigation and then Support.
Thanks - it’s not in the box. I’ll try to reach out to support.
