I had this problem:
For Oculus GO, my home wifi network was invisible. He saw the surrounding wifi network but not my home. But the home network was fine - all other devices connected without any problems.
I repeatedly contacted support, but all the advice was without results.
This solved the problem:
In the settings of my home wifi router, in the settings of its Channels, I changed this setting from "Auto" to a fixed channel number "5". And that's all! Since then, the Oculus GO connects perfectly.
This change has no effect on the operation of other devices in my home. I hope that this solution will help someone else ...
