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.
