My wireless connection between my HP laptop and my Photosmart C1800 all in one is properly connected with a succesful diagnostics report (signal strength excellent) but I cannot get the printer to print either photos or documents. at the first attempt I did not set the correct properties for a document and the printer indicated there was no paper (It thought I requested a photo). I cancelled the print by pressing the cancel button on the printer and since then I cannot get the machines to print by wireless communications.

Network troubleshooting
If you are encountering issues using your HP Photosmart over a network, try the following steps in the order listed:

1. Turn off the router, product, and computer, and then turn them back on in this order: router first, then the product, and finally the computer. Sometimes, cycling the power will recover a network
   communication issue.
2. For wireless networking issues, run the Wireless Network Test from the product control panel.
   
   1. Press Setup.
   2. Press the down arrow button until Network is highlighted, and then press OK.
   3. Press the down arrow button until Wireless Network Test is highlighted, and then press OK.
      The Wireless Network Test prints.
   If a problem is detected, the printed test report will include recommendations that might help solve the problem. If you need to change the network settings on your product or have never run the Wireless Setup Wizard, do so now.
   Double-click the HP Solution Center icon, click Settings, click Other Settings, select Network Toolbox, and then select the Wireless Setup Wizard link.
   
3. If the previous steps do not solve the problem and you have successfully installed the HP Photosmart Software on your computer, run the Network Diagnostic tool.

NOTE: The diagnostic test might prompt you to connect a USB cable between the product and your computer. Position the product and computer near each other and have a USB cable readily accessible.
To run the Network Diagnostic tool. In the Solution Center, click Settings, click Other Settings, and then click Network
Toolbox. On the Utilities tab, click Run Network Diagnostics.If you are unable to run the Network Diagnostic tool or it does not help solve the problem, check the following sections for additional information:

1. Make sure that the computer is connected to your network
2. Make sure that the product is connected to your network
3. Check to see if the firewall software is blocking communication
4. Make sure the product is online and ready
5. Make sure the HP Device Discovery software is running

use wired, wifi , is and always will be problematic.
I have 2 printers here, both new, both have wifi and both wired.
usb.
not by accident.
we have wifi camera;s here too.
and are fussy at times, you do know its radio tech. right?
and subject to signal noises and jamming in the hood.
move wifi to a higher channel, force it.
or use

Hi there,
Does your printer connect to your network ok? Have you connected it to your wireless network before trying to "find" it on your laptop?
Does your wireless network have a router/switch/firewall?

Connect wireless Or LAN?

If you need more help post back!
Thumbs and testimonial are welcome!

Have you added it to your Network?

The one that is missing in the network is the printer.So try to reconfigure the IP of the printer again using the wireless wizard in the printer manager. Or go to Using the HP Network Diagnostic Utility in Windows - HP Customer Care (United States - English)

Also ; Very seldom does the printer itself cause problems. To determine if you have printer trouble, do the following:

• If you're using a wireless connection, see if the wireless indicator lamp is illuminated? Can you turn on the wireless radio from the control panel of the printer?
• Print a Network Configuration page and a Wireless Network Test report from your printer's control panel, if available.
  • Does the Wireless Network Test report indicate trouble?
  • Does the report indicate that the printer is connected to your wireless router, and not to a neighbor's? The network name the printer is connected to will be shown on the both the Network Configuration page and Wireless Network Test report.
  • Compare the printer's IP address [X]
    IP address
    An IP address is a series of numbers by which computers, printers and other devices on a network are known. An IP address is usually issued by the local wireless router (network) from its DHCP service. A device is given an IP address that is similar to the wireless router's IP address. For example, if the wireless router's IP address is 192.168.1.1, a printer may be given an IP address of 192.168.1.5. to the gateway IP address [X]
    Gateway IP address
    This is the IP address of your wireless router. . They should have a similar format (for example, the gateway IP address might be 192.168.0.1 and the printer IP address 192.168.0.5). If the printer has an IP address similar to 169.254.XXX.XXX, it probably is not connected to your wireless network.
  • On some printers, the Network Configuration page will list all wireless networks detected in your area. Is your network listed among those found? Does it have good signal strength?
  • Are there several wireless networks on your same channel or using channels close to your channel? You should use a channel at least 5 channels away from the closest used channel. Consider changing your wireless router's channel to 1, 6 or 11.
• Are there any error messages on the printer or unexpected blinking lights (consult your manual to determine what to expect)?
• Reset your printer (usually by removing the power cord from the back of the printer, waiting 30 seconds and then reconnecting the cord. Consult your manual for specifics).
• Restart your wireless router [X]
  Wireless router
  A wireless router is networking hardware that allows both wired and wireless devices to connect to a network. When connected to a wireless router, devices such as computers, printers, and other Wi-Fi enabled electronics can share one Internet connection AND connect to each other. Connections can be made to the wireless router through a wireless connection or a wired connection using an Ethernet cable. by unplugging the power cord, waiting 60 seconds, then reconnecting the cord to the wireless router.

you have problem with router range your laptop has been not get proper signal from the wireless router when got signal you get password screen then after due to signal is week the connection will lost

First thing to do - check wireless is turned on. It sounds basic, but sometimes the switch can get knocked, meaning that the laptop won't recieve any wireless signal. If this doesn't work, play around with the settings for a while - if you're running Windows you can go to 'network connection' in Control Panel and right-click on your wireless connection; go to 'repair' and the repair wizard will go through it to try and fix it. Make sure both the wireless switch on your laptop is turned on, and that your modem is turned on too.
If this doesn't work, go to your modem's setup page (usually a web page - the address will be in the manual) and choose a different wireless channel - 0, 6 and 11 are the only non-overlapping channels. You may want to adjust your wireless signal power to make sure you have enough signal. You might also want to run a diagnostic on your modem to see if it is running properly. Some modems will display on the setup page which computers are active. See if yours comes up.
If this still doesn't work, you may want to go to an internet cafe or other wireless hotspot to check whether it is your modem which is at fault. If you get a signal and can connect, then it may well be the modem at fault. Check at some other locations just to be sure. If not, it sounds like the wireless card has a problem. If it is an internal wireless card, you might want to take it back to the manufacturer for repair. If it is an external wireless adapter, you may just want to replace the card or adapter to see if this helps.
Hope you work it out, and that you get your wireless connection back soon!

jdawg01,
