Hi

Can you brief me the problem you are facing?

Can you tell the printer name ?

did you install the software CD of the printer in the computer ?

did you make configuration changes for the printer to detect your computer

Were you previously using the printer with USB or Ethernet connection ?

ok

can you connect the ethernet back and verify if it is working now

Change from an EthernetconnectionUse the following instructions to change from anEthernet connection to a wireless connection.NOTE: For Ethernet-enabled HP devices only1. Open the embedded Web server (EWS). For moreinformation on the EWS, see the electronic UserGuide available on your computer after you installthe software.2. Click the Networking tab, and then click Wireless(802.11) in the left pane.3. On the Wireless Setup tab, press Start Wizard.4. Follow the onscreen instructions to change from anEthernet connection to a wireless connection.5. After you finish changing the settings, disconnect theEthernet cable.

can u try these steps ?

if the printer has no port for cable, how did you use it with ethernet cable ?

ok.. so the scenario was like the printer was wireless printer and you were using it wireless on ur computer. Suddenly, it doesn't work wirelessly....am I right ?

Can u provide me ur email address ? I will email you the troubleshooting document of this printer.

Without router, is ur computer and printer communicating ?

1. Make sure the wireless (802.11) light is turned onIf the blue light near the HP device’s control panel is notlit, wireless capabilities might not have been turned on.To turn on wireless, press the wireless button (locatednear the wireless light) once to turn on wirelesscapabilities. Or press the Setup ( ) button on theHP device’s control panel, select Network, selectWireless Radio, and then select On.

2. Restart components of the wireless networkTurn off the router and the HP device, and then turnthem back on in this order: router first, and then theHP device. If you still are unable to connect, turn offthe router, HP device, and your computer, and thenturn them back on in this order: router first, then theHP device, and finally the computer. Sometimes, turningoff the power and then turning it back on will recover anetwork communication issue.

3. Run the Wireless Network TestFor wireless networking issues, run the WirelessNetwork Test from the HP device control panel:

HP Officejet J4680All-in-One seriesa. On the HP device’s controlpanel, press the Setup( ) button.b. Select Network Setup,select Print NetworkSettings, select WirelessTest Report, and thenpress OK.

HP Officejet J6400All-in-One seriesa. On the HP device’s controlpanel, press the Setup( ) button.b. Select Print Report, andthen select Wireless Test.

If a problem is detected, the printed test report willinclude recommendations that might help solve theproblem.

a. On the HP device’s controlpanel, press the Setup ( )button.

b. Select Tools, select NetworkSetup, and then select RestoreNetwork Defaults.

I think the problem is that the router and the printer have different SSID

can you navigate to the router device setup in your computer ?

you should find it where you have the wireless network card icons appear in Network Connnections under Control Panel

ok...right click on the router and select Properties

only these two ... Show up ?

is the firewall Broadcomm your router ?

Once the property window opens, can you navigate to the Wireless Networks Tab

There you should find something listed in a box. Please select it and click on Properties Button

I have understood your issue .. The Issue is that the router is having different SSID and printer is having different SSID

so both are not looking for each other

Setting up SSID should be done by the technicians of the devices.

I am not sure of the SSID setting.
