Remeber wifi pass?

Default installation makes disposable network stack, which is secure but has the quirk of having to manually enter wifi pass every time the pc is rebooted.

Is there a way keep the flexibility of a disposable network stack while also automatically logging in to wifi ?

Hope this help.

You can save it in sys-net’s disposable template.

Even tried with non-disposable sys-net. It does not save wifi credentials.

You connect to wifi by entering the credentials from the wifi drop down at the top right of DOM0 screen.

Is there some other way to save the wifi credentials that I am unaware of ?

Yes, it does - at least, for every non-disposable sys-net I have seen.
You’d need to provide vastly more information to convince me of this.
