But I will try a few common issues. Can you share what CHANNEL the Router has the WiFi on?
I've suddenly lost my wireless connection, (which had been working fine for months), to my HP Laserjet 100 color MFP M175 color printer.
My wireless router is working fine, with no broadband connection problems. I've followed the (rather complicated) HP 'Help' pages, which basically suggest I hold down the blue 'wireless button' on the printer panel for 2 secs until it flashes and counts down from 2 mins. This is supposed to reconnect the wireless network, but I just get an error message 'Connection failed'.
I'm not an IT expert, and need someone to talk me through fixing this.
