Apple Music causes constant WiFi dropping on iPhone 6s

Hi there everybody,

I have a problem I just can't get rid of.

I have iPhone 6s and a subscription to Apple Music.

Every single time I want to download music to my phone or just stream it from my Apple Music account, doing so causes constant WiFi dropping after just few seconds. Basically said, I can only use Apple Music with mobile data, but since I don't have the unlimited plan for it, I really need WiFi to work.

No other app causes such problems, nor on my iPhone or Mac, where Apple Music seems to work perfectly.

It's just the combination of Apple Music and the iPhone ...

Reseting the settings/router/phone, forgetting the network, renewing lease and changing DNS didn't help at all.

Has anyone had similar problem? How did you solve it?

Many thanks in advance!

Cheers,

Nina
