Swop sky hub to the same

[Zingbah]

My sky hub router has gone wrong. Sky  say they need to send an engineer again out  to replace it but won't come out for a week, so can I buy a second hand one on Facebook marketplace or eBay and just swop myself? Would it need to be exactly the same (it's the newer box) or would an older one be ok? I can't not have Wi-Fi for a week so need a solution today

We have to advise that almost all Q Hubs and all Sky Broadband Hubs and Max Hubs are loaned by Sky, not sold to subscribers, so the legitimacy of any you may find available elsewhere is distinctly dubious.  They may or may not work, and if working may or may not continue to do so.
