@Al94 So far so good with the Apple devices using the guest network there have been no issues.

@TP-Link Thanks for the suggestion, will give that a go. Unfortunately our son is the only person we know who uses Apple devices so will have to wait till the 21st to see if it works!

Home network, BT Infinity FTTC. Normally trouble free until our son visits and uses his iPhone and Mac, all our devices are Windows/Android. When he is here my wife and I frequently lose internet...
