I was given some very good info on resolving my connection problem with my laptop. But, regardless of the fact that I cannot connect my mac to my desktop...acting as a server for my printer, I am perplexed as to why....after clicking the plus sign on seeing what printers I do have available. Nothing shows up. I look in the library and there are many listed, however I get zero results. I don't think it matters that my desktop is now using Windows 7. Because, I think, I should still be able to see what printers I have available. Even if I can't connect to my network printer. My wife's laptop pc connects just fine. And....several weeks ago, before my wife had a laptop...she had a desktop with a wireless adapter. I was able to connect to my printer. It wasn't listed, but....I used my wife's printer....a similar HP...and bingo! My wifi connection worked with my printer. I feel like I'm in the Twilight Zone or something. Any help would be greatly appreciated.
