Ok so on PB1 I had issues connecting to the secured WiFi at work. But with PB2 & PB3 I was able to connect with no issues. But now with PB4 I can't connect my iPhone 6 plus. However my iPad Air 2 and iPod touch 5th gen are both on the same public beta and will connect. I've already tried resetting my network settings to see if that would help and I still got nothing. When I put the info in it says that it can't find the network.
