Can you open a terminal and post the output from

sudo lshw -C network




iwlist scan


rfkill list

sorry about taking so long to get back to you mark. how can I cut and paste the replies to to your code questions from a usb stick

Connect to your router with an ethernet cable

Or copy the output to a text file then copy it to another PC

Have you tried switching your firewall off? Because sometime firewall causes some issues while connecting to the internet.
