I have a HP Photosmart C4380 printer which has been working perfectly wirelessly, until I updated my broadband router yesterday. It now only works when connected by usb cable. The original cd set-up disc cannot be used with my present os. I have tried many attempts to re-configure the printer but seem to be getting nowhere.
I have tried both suggestions but still getting nowhere. I can print via USB connection but not getting anywhere with a wireless connection.
I think the problem is that the SSID needs to be amended to the same as updated wireless router but I just can't find any instructions on how to do this.
After a lot of time and frustration I have managed to solve the problem at last! I did a re-boot of my router and downloaded the installation of the printer from the HP website as suggested whilst disabling virus protector and firewall and printer now printing wirelessly quite happily - and so am I!
Thanks to all of you for your help and suggestions.
