Everything seems to work well with my Z3100. Prints great, output looks great, no errors. The issue is when I am trying to upgrade the firmware. The response in the web browser is ridicuously slow (Windows Vista, ethernet connection). When I put in the network address it takes 25 minutes before the Z3100 responds. Until then the web browser just indicates it is waiting for a response. I then clicked on the settings tab and it took over 30 minutes. I do not have a proxy server, which is the only thing I could find to look at in the HP documentation. I have tried this with IE7, IE8 and Google Chrome. Same response every time. Any ideas on what is going on here?
