two issues that are so frustrating: 1) I have HP LaserJet printer. Often when I go to scan via Image Capture, I get a response that "no camera or scanner detected." I try and try and try again, sometimes it pops up, and sometimes if I reset computer it works. But, anytime I print, to the same device, it prints no problem. 2) I have my mac online via wifi and ethernet cable. at least ten times a day the mac loses internet connection, I turn wifi off then right back on, and it works. why would I lose connection, and why wouldn't ethernet work even if wifi has an issue? I work from home and am scanning and online all day, so this is so annoying, any help would be greatly appreciated.
