Connect two wifi network at the same time

[Homeye]

I remember that about a year ago i found a setting for connect 2 wifi network with my phone, but i had to disable it because it made some problems with vowifi calling for me. Now, i can't find it where can i turn it on. Please help me to enable it, i know (think ) it's real and i'm not just imagining it
(I have a lmi with the latest miui14 stable)

Tap on Wi-Fi in the settings, then select Network Acceleration. From there, you can connect to two Wi-Fi networks.

The thing is that there's no settings for it and when i try to turn it in via the Activity Launcher, it's grayed out.

Have you tried clearing the cache or app data ? Otherwise, I have no idea... I'm sorry.
