Can't download Apps on TV, Phone + Tablet

[HelenLuLu]

A previous problem has returned. I really don't know why. I can open emails, watch normal TV but any apps like netflix or ITVX will not open. It went on for months and suddenly started working for a few weeks and now stopped again. Any ideas what's wrong?

What is the name of the EE BB plan are you on including its speed? Which EE router & WiFi extenders, if any, do you have (read label or post a pix)?

[HelenLuLu]

The BB package is the essential full fibre 150 and speed is 100Mbps.

no extender. 

Do you want me model number for the router. I'm  on my third router.

@HelenLuLu Yes @XRaySpeX asked you for it,, and only the third one you have a few to go yet!

[HelenLuLu]

I was away yesterday so sorry for my late reply. Please don't say that! Three is enough. F5394-CP EE

You mean the Smart Hub Plus (SH31B)? 

[HelenLuLu]

Yes

So what happens when you try to d/load apps? What's the error msg?

[HelenLuLu]

All different. ITVX just doesn't open. Netflix states an error code.  Argos app states network failure, Tesco app says no internet connection
