Ipad pro and ipad 4 shows connected, but no internet connectivity

I have the latest firmware.  I have android, windows 10, numerous wireless Tvs and two ipads. ipad 4 and a ipad pro.

Everytime we go to pick one of the ipads up and open a browser nothing loads.  Wifi shows its connected rather its 2.4, or 5ghz. you have to manually disconnect and reconnect to get back on the internet.  I haven't found anything on search. If anyone has any suggestions I would appreciate it.  This is the only Netgear router that I have had constant issues. The other devices are working fine when the Ipads arent connected.  All updates are up to date.  I have a motorola cable modem
