I own a HP 2840 printer. It has a wifi connectivity. At my home there is a linksys wifi router. The printer is configured for all the wifi to share. When the computer goes to sleep the printer went offline. I have to find it again the printer and faxes section. It has become complicated to make this thing constant. It is just not getting online at all. Is there any way by which I can keep this constant. On startup the printer is detected but when I wake the system from sleep mode it is lost.
