Not sure what else to do. Tried hard reset and everything's fully up-to-date. Wifi keeps slowing to a crawl -- issues especially obvious when playing live online games (Poker, Pool, SSG2). I'm open to suggestions on how to fix it. Painfully unsatisfied with Apple recently and I pray there's a simple fix that I've overlooked. I'm on an iPhone 5S. Does anybody have any suggestions please?
