I have an iPad 2 running iOS 9. Ever since I upgraded from iOS 6 to iOS 7 a few years ago, I have slowly been noticing the wifi connection drops out very fast when I leave the room with the router. The connection is terrible after going about 10 feet from the router. My iPad 1 with iOS 5 connects very well. I have two routers connected to a switch, an Apple Airport Extreme Snow 2003 and a Linksys WRT54G. All other wifi devices connect fine, so I don't think it's a router problem.
Thanks in advance.
