L7680, and cannot connect HP Solutions wirelessly, works fine through USB?

Question

Here's the deal, I have 4 computers in the house and we are all hooked up to the same printer wirelessly and with vista we all had HP Solutions which allowed us to scan and the other commands that solutions allows, now with 7 it recognizes the printer and allows us to print, BUT when we tried to hookup HPsolutions she could not get her laptop nor her desktop to recognize solutions, and soon gave up a long time ago and just excepted the fact that she can't scan and will just ask her husband to scan for her... Don't like it but I guess I have to except it for now, well I investigated the forums a bit more and was able to get the full version on my desktop through the USB cord only, which works but is not what the intent is... my desktop is the stronger of the 4 so I don't want to even tamper with the lesser 3 until this is solved with my desktop 64bit with 7                  COME ON GUESS HELP ME OUT

Answer 1

I had a similar problem with my OfficeJet L7680 and here's how I fixed it.  
18APR10 - from Dan
     I lost my L7680 network link (using CAT5 from printer to router) and could not print to it over the network.  However, I could print from a PC with a USB cable directly to the printer, but there are currently three PCs connected wireless to the network.  I think I have a viable solution for anyone with the same problem and is not related to the operating system of the PCs.
     Originally, I went to the HP site and downloaded the program for the L7680, Critical Update to Enhance Reliability of Network and USB Connectivity and Improve System Responsive....  This worked wonders until my modem and/or router went down.  I could see ink levels from my PC, scan, print, and so on.  Then I somehow lost my network connection again.  When I checked the network settings on the L7680 printer panel (Setup, 5 - Network, 1 - View Network Settings, 2 - Display Wired Settings), I noticed a different IP address than the original 192.168.1.100.  Once I figured out how to reset the printer to that one, it connected and worked as it should. 
     Here's how to reset it:  1.  Power down all devices (wired and wireless) to the router (I even disconnected the printer power cord and CAT5 cable at the printer); 2. Power down the modem and router - wait a minute or so before powering back up;  3.  Power up the modem and give it a minute or so to go through system checks, which will normally acquire a new IP address from your ISP;  4. Power up the router and let it go through its system checks; 5.  Connect the CAT5 cable from the printer to the router and power it up before you power up and connect any other computers.  This should assign the printer the first IP address from the router, which should be 192.168.1.100.  Once the printer goes through its start-up checks, you can check its assigned IP address from its panel.  6.  Power up any other PCs or devices to the router.  They should be assigned successive IP address numbers from the router.  You can check these using a browser in the PC after typing in 192.168.1.1, logging in to the router, and checking the appropriate place in the router driver/software displayed in the browser. 
     I was not able to reassign IP addresses in my router's driver/software to individual devices, but this method did the trick.  I did not try to change the IP address of the printer from its panel to match what had been inadvertently reassigned to it.  That might be another option to synchronize the printer and router with the same IP address.  If the printer loses its connection again, you'll have to synchronize what the printer has with what the router shows.  This worked for me.
