Haven't updated my iPhone 7 since iOS 11.x. Recently updated to 14.2 and instantly got 5 GHz connection hanging problems. Restored from FDU, resetted network settings - nothing helps. 5 GHz keeps hanging in minutes to hours after connecting. Reconnection helps sometimes, but not always. Usually rebooting the device helps, but now I'm just using 2.4 GHz instead. 100% software issue.
