Connection loss

[Kevb27845]

Why do I keep having messages on my TV and phones saying connection lost or unstable?

[JimM1]

@Kevb27845 Is the message correct and you are having the issue with both or more off the devices!

[Kevb27845]

Yes,  and security cameras always display unstable network

@Kevb27845 It may be worth running the service checker and diagnostics, then having a look at the devices in the test, if you have a poor/weak wireless wi-fi signal too them it may be able to indicate that too you! As you have now added more devices on the posting then time to look at the wi-fi signal strength around the property!
