Hi everyone, this is my first build.
I have the TP-Link PCI Express Wifi Adapter (N) installed and wifi works flawlessly. When I first set up el capitan I was able to access the app store and download Xcode. Now when I try to download or update apps it tells me "Your device or computer could not be verified".
I have searched around and I have seen people say I either need ethernet or a wifi adapter such as the one I have. I cannot run ethernet to my machine and do not want to even try (too far from router). I found this solution: http://ift.tt/1P5gz6V which says it should be last resort after having PCIe wifi device but I cannot find a fix for having the wifi device.
Any advice? Thanks!
