HpL7780 wireless freezing up printer

Just bought this printer and was setting up the wireless wizard on it. I recognised the linksys system that I have, then said is was successful in setting up the wireless process then it freezes. the only solution to this that i have found is to plug out the printer power cord then reinsert it. The wireless does not work. It prints if connected via usb and it scans , havent tried the fax as yet. A number of persons online seem to have the same problem, some have solutions but these dont seem to work for me. HELP!!

I have the same problem. But if the printer is close enough to the linksys wireless router, you can workaround it by connect it directly with a network cable.

    You will need to disable the wireless to undo the freeze. Follow the instruction on the HP site on how to disable the wireless.

Connecting a brother hl2170 wirless printer to a linksys wrt54g

Take note all the wireless settings of the router first. Now go to the printer and Press Menu/Settings, look for wireless setup wizard. It should find the network, highlight it and connect. If it asks you for the network key, type your wireless network key. It only allows WPA-Personal(TKIP) and WEP. If you have WPA2 or AES, it will not connect

HP printer cannot find access point and I'm not sure what to do.

You must first connect your printer to the pc using usb cable, then run installation wizard that is on the CD that came with the printer.

Wizard will guide you through the setup orcess where you will provider your routers ssid (linksys) to your printer, and your printer will use that ssid to connect to your router.

After the Wizard setup is done, it will tell you to disconnect the usb cable and only then your printer will work on wireless.

Good luck,

Trying to network xp pc to wireless laptop

Right click on the drive you want to share. Ex: C:\Vol-xx = name. In the pop up window click Sharing & Security. This needs done to all the drives you want access too. To share a printer. Everyone must have the printer drivers installed. The Pc that has a direct connection to the printer must also Share the printer on the network. Open Printer & Faxes, highlight the printer you want to share. Click File than click Sharing follow windows instructions.
Small suggestion regards to the wireless side of the network. Suggest you setup security so others close too you can not tap into your network. (common).
