Have Dell laptop with Windows 7 and IE9, HP Deskjet 3050, Orange Livebox router all set up wireless. Has been working fine for months and now suddenly can't print wireless from internet. MS office docs work ok and everything works ok with USB connnection. I have uninstalled / installed printer and s/w, download latest drivers, rebooted router but still no joy ! Wife's laptop works fine on same home network. Laptops, printer and router are in same room no more than 1 metre apart. There are no metal or magnetic obstructions. HELP !
