_jis_It still doesn't work
One restart is sufficient, consecutive restarts cannot help you more 🙂
But if this doesn't help, then go to the Settings / System / Reset options / Reset Wi-Fi...
CedricJuricanDo you have problem only with your wifi router, or with any wifi router in 5GHz band?
It still doesn't work
MonarkYep I updated just now and I too feel that vowifi isn't stable because although I am connected to the wifi network and sitting near the router still it keeps on fluctuating between vowifi and volte. Hence, I don't think it's a signal strength issue. If at all it's a strength issue then this feature is useless on this phone because you can't be sitting near the router everytime.
you are using jio or airtel?
This update only enabled VoWifi for jio only
Still it is cutting off it is not stable
