Using the Plusnet supplied Plusnet Hub One (the cream one with the big blue light on the front, I think it is a repackaged BT Home Hub 5) when a particular client connects (a Humax PVR) the wifi on the hub crashes every time. It was ok on the previous (ADSL) router. Is there a known issue with these hubs? Is there a firmware upgrade available? It is currently running version 188.8.131.52.184.108.40.206.2.
