A USB cable wasn't included with the printer.
Yes, there is a WPS button. The router is a BT Homehub 3.0 type A
I've done both. Only green left hand side Wifi button now on. On my PC a pop up appeared with our Wifi address. I clicked the Password XXXXX and the Admin Password XXXXX Clicked through after this and now can't get any further 'printer can't be located'.
Both wifi lights are now solid on the printer
'Printer not found...'
No printer is coming up. Should I click on 'The printer that I want isn't listed'?
Yay! It's now listed. Still won't print, but that's probably because it hasn't been used before, so I'll keep trying. Thank you very much indeed.
