My iPhone 6 is still randomly disconnecting from my home WiFi, even after the latest OS update. My spouse also has an iPhone 6 and has experienced no issues with WiFi connectivity. When I spoke with Apple earlier in the week, I was told that they were aware of this issue with iOS 8 and would be working on a solution that should be released in 24 hours. I have a $700+ phone that doesn't stay connected to WiFi. Ridiculous. Apple really needs to get it together. This is the worst OS release yet.
