Hardware: TP-Link Archer MR200 v1 (v1 00000001). (https://www.tp-link.com/se/download/Archer-MR200_V1.html#Firmware) And an iPhone 6.
Current Firmware Version: 0.9.1 1.2 v004a.0 Build 180502.
Operator: Tele2 Sweden.
Problem: Call a call via Wi-Fi.
Hey! Earlier this week I start with the idea to start using Wi-Fi calls, because my mobile coverage is not so good indoors. When I first activated it on my iPhone 6 (this phone allows Wi-Fi calls from Tele2 Sweden) it didn't work. I googeled as creazy to try to find a solution and succeeded at the end when I found this article: https://community.tp-link.com/en/home/forum/topic/97458?replyId=205283 and updated firewall in the router . I tried calling on Wi-Fi and it worked fine, I also saw "Tele2 Wi-Fi" in the upper left corner of my phone.
When I carefully read the name of the file I saw it was a "beta file", so I wanted to update to the latest version to make sure I have a secure network. So that's what I did, I uppdated to 0.9.1 1.2 and now the Wi-Fi call no longer works :( I don't see "Tele2 Wi-Fi" in the upper left corner of my phone even though I stop and start it.
I really hope someone can help me with what to do, I can't do much about networking.
