So I think this has been an issue with ios9 in general but i have not been effected till now. iphone 6S+ updated to ios9.2 and my home wifi has been terrible. I used to have wifi calling and now I don't anymore and now My backups won't run, my email is hanging, and surfing the web is painful. If i switch to my data connection all if fine. I have tried to trouble shoot a few things as far as deleting and re-adding my wifi connection. Reset network connections reboots and also even trying to change my DNS on my phone and router. Nothing seems to improve it. Anyone have similar issues and have any sort of resolution?
