Hi I have a nx200 5 g router and having trouble with it dropping the WiFi because it keeps swapping from 5-4 g then it comes back so I have configured it to use 4G only I am on top of a hill and there are various transmitters around , I have a external aerial with 5m leads not shorts ones and it's up a pole outside   I have the weather app and under the image of the nx200 is a signal strength bars but showing amber colour and not many I have configured the ex aerial in the settings do I go up a ladder to twiddle it to get better signal or is my external not compatible thanks mark
