Please help, I have spent 2 weeks trying to help out a friend with this issue.... HP Officejet 4500 G510n-z keeps losing its wireless connection. Re-install resolves the issue but only for a short while before it loses connection again. I have resulted to borrowing the printer and attaching to my laptop to spend time researching the problem. Both laptops running windows 7 Home Premium x 64bit. I also lost wireless connection.
I am so glad that I found this post however on following the steps I am unable to locate the 7z folder (at step 5). I ended up copying the whole download to the desktop and following the rest of the steps, opening the Util... Open CCC etc... I am pleased to report that for the first time ever the printer scan operation is actually working wirelessly now and other functions seem ok however I am not sure how long this will last. Should there be a time that I need to go through the whole process again..... please advise how I locate the mentioned 7z (example 7zS2356) file. I will be returning the printer to my friend later this week and will need to go through the whole process again to connect the printer back to her laptop.
