Initial wireless activation freezes unit

After finding out the hard reset code I have simply plugged my printer into my D-Link router via ethernet cable, problem solved using this workaround. Obviously this doesn't resolve the actual problem which is using wireless to connect the printer, but this solution works for me since both printer and router devices are next to each other in my office.

1. The wireless configuration cannot be used with any security protocol, or it will always freeze. It might be possible with MAC address filtering, but haven't tried it.

2. You need either a cross-over cable, wired hub, or wired router. In my case, I used an old Linksys wired router which gave out DHCP addresses.

3. Un-plug the HP L7780. Un-plug your wireless router.

4. With no wireless AP on, plug in the printer. Patch it to the wired hub so it gets an address. Patch your laptop/computer to the same router and get another wired address. Alternately, you could use a hub or cross-over cable and assign the L7780 an IP and subnet mask thru the front panel such as 192.168.1.101/255.255.255.0 and assign you computer a similar IP--192.168.1.102/255.255.255.0. If a hub, plug each into hub, if a cross cable is used, connect computer and printer directly.

5. Open your browser to the printe's IP, ex. 192.168.1.101 and the embedded web applet will appear.
Go to the networking tab and click on "Wireless networking" and assign the IP, subnet mask, gateway, and DNS server (on home network, same as the gateway) of your preferred wireless network.

6. Click "apply" or submit; click thru any warnings about not being able to connect.

7. Disconnet devices from wired hub or cable and plug in your wireless AP. In my case, the L7780 did not retain the IP I assigned, but did acquire a new DHCP address from the AP.

8. Print out config sheet, open a browser, go to the assigned IP and change the settings to the ones you want.

I just started having this problem today after I upgraded my old Linksys router to a WRT54GS.

This is not just a Linksys issue, I am having the same problem with a new wireless router from Rukus. I have attempted to connect with various security setting, including none, and the printer freezes after it connects to the router. The printer works fine when I try to connect it to my DLink wireless router.

Beth, Any details on what firmware version worked for you. Have a WRT54GS V7 -- and having same darn issue!! - Jen

Thanks, Beth. I am only on my 2nd L7780 unit but am struggling with the exact same problem. Which Firmware patch did you download from the Linksys website? Thanks, Sharon
