I was forced, yes forced last October to change my broadband to EE, since then I have had nothing but trouble. I'm waiting for my fourth new hub, these things are rubbish and fail on a very regular basis, if this is the power of the new partnership then I suggest you split up again as sine BT has been with EE it's rubbish and you have not done yourselves any favours joing with this bunch.
I understand customers can go back to BT or should I just go to PlusNet another BT company.
Little comfort to you but my EE wifi 6 hub works perfectly.
As your only a few months into your contract there will be hefty financial penalties if you left.
Far simpler is to buy a new SH2 or the plusnet equivalent ( both literally the same router) from Ebay and swap them over.
You can pick one up new for around £10.
@Augusta, what symptoms are you seeing when the routers fail?
