At/on/for/through open WiFi network

[germanictamoon]

What preposition would a native English speaker use before WiFi in the following sentence?

Don't access your account at/on/for/through open WiFi network?

I think 'on' is better.

Thank you very much.

Hello,

I agree with you but feel you should have the indefinite article - 'an open wifi network.'

Don't access your account at open WiFi network?
Don't access your account on open WiFi network?
Don't access your account for open WiFi network?
Don't access your account through open WiFi network?

Is that what you are asking? Don't you think there's an article missing? Both "on" and "through" work.
