Poor wifi with upgrade to ultrafast plus

[ceri17-18]

We've recently from super fast to ultra fast plus and the wifi ever since has been awful. Keeps switching to 3G on mobiles and Netflix etc won't load. 
have done the usual box reset etc as advised from Sky but still having the issues. 

anyone had anything similar?

@ceri17-18  Did you have to change the router you had when you had superfast to ultrafast?

[ceri17-18]

No, kept the same one

@ceri17-18  Really odd that it should change with the different technology for you to get your internet it is only a data bearer. Which router do you have from the link below.

Broadband hub.

@ceri17-18  Was the router placement changed when you went to ultrfast broadband to connect it to the ONT?

[ceri17-18]

Router is next to tv. We've had no new router but new port fitted on the wall

@ceri17-18Did this change happen as soon as you got ultrafast? Do you have any devices connected via ethternet?

[ceri17-18]

Yup, as soon as swapped over everything has been poor. 

it's all wifi

Same thing happens with mine

[Highlinder]

@ceri17-18  Have you spoken to Sky about this happening to see if they will send out a new router to discount any issue with it?

[Highlinder]

@Qaiser1  When did you change from Superfast to ultrafast broadband?

[ceri17-18]

Yes. As soon as swapped over the issues started 

[ceri17-18]

That's the next step, spoke to them today to do the usual restart and reset of everything and still the same 

[Highlinder]

@ceri17-18  So what is their next steps if you spoke to them today and they could see no change.
