I've just moved to BT Business FTTP with a Smart Hub 3 (replacing a Smart Hub 2) with the Hub 2 I had a wifi repeater disc (the black business one) but that doesn't work with the Hub 3 (BT confirmed that - and offered to supply a disc that does work at an outrageous monthly charge)
I don't understand all the technical stuff so - does anyone know if this gadget from Amazon
https://www.amazon.co.uk/dp/B0CSD8GL7W/?coliid=I26HYRXPSTMH8P&colid=ORYXZ3U6EPBY&ref_=list_c_wl_lv_ov_lig_dp_it&th=1 will work with the Hub 3?
I'm willing to give it a try as being Amazon it can go back painlessly, but I'd like some comfort that it might work/
AND if anyone is interest the existing black disc which works with Hub 2 (it's as new) is for sale at £45 posted (BT sells them for £100, they seem to go on ebay at anything between £45 and £75)
