How do I buy a Smart Wifi SW30A Disk?

[RJSin07]

I am trying buy a 4th Smart Wifi Disk. I cannot find how to get a Smart Wifi SW30A Disk through the EE Store. I have 3, coverage is not good in my office. I am willing to pay for the 4th disk but, I keep getting put into a perpetual loop... I have checked the EE Store and I cannot find this anywhere. 

This is the link EE keep sending me: https://ee.co.uk/broadband

@RJSin07  Do you mean one of this  ? 

if you do I believe it’s no longer available as EE have updated their routers.   You can get these on eBay but I think the max you can connect to the router is 3.

Did you manage to get an additional one, I currently have 7 BT whole home discs and Ive been sent a new router and 3 W30A extenders and cannot seem to find additional ones, Ive called EE and they directed me to amazon, the model there is w10A and the feeback from some purchasers was that the W10a isnt compatible with the newer model
