So I have a wifi network with AT&T Gigapower router. My iMacs same age as my iPad 2 and from its report it is showing Supported PHY Modes: 802.11 a/b/g/n and is connected to my wireless N network. Speedtests from the iMac show about 300Mbps however speed tests from the iPad only shwq about 30-40. I have reset network settings, erased everything on the iPad and set up as new, tested my wifes iPad 2 and get similar results as my iPad. It appears that even though it is connected to a 5Ghz wifi network its performance is 10 times slower than iMac and iPhone 7 on the exact same network in exact same locations in the home. Both iPads running iOS 9.3.5 Any ideas ?
