Hi, I am using Airtel 4G Hotspot, and VoWiFi is working perfectly. I bought this TP Link TL-WA855RE 5.0,
and When i am using extender Signal, its not working. I am not getting VoWiFi . I tried upgrading firmware,
but found I am using Latest Firmware.
Pls help me, if there are any settings to fix it.
