I've been having a similar problem: I have a D110A printer and a MacBook. My printer connected easily to my old network, but since I moved to a new residence and opened up a new internet account, it won't accept my WPA PASSWORD.
It's cable internet (Comcast), and I have a modem/router combo device that's Motorola brand. My roommate hasn't been able to set up her wireless printer either, so I'm guessing it has something to do with our modem device, but I just don't know how to fix the problem.
Any help would be greatly appreciated. Let me know if there's any info I've left out.

OK, let's do a couple of things:
1. On the printer go to Setup > Network > Restore Network Defaults.
2. Cycle power on the router (pull the power plug and let it reboot - about 3 minutes).
3. Back on the printer: Setup > Nework > Wireless Setup WIzard. Follow the prompts.

Thanks for the tips. This, unfortunately, did not work. The printer still won't accept the WPA password, even though my computer connects to the network just fine with that same password. I'm not sure where to go from here.

I have the feeling your wireless router is not configured correctly. What brand is it and is it issued by Comcast or is it yours?

OK, then assuming you can get into the router and configure it check these things:
1. Make sure that 802.11g is enabled, along with other modes like 802.11n is fine, but 'g' must be present.
2. Disable MAC filtering
3. Broadcast your network name (SSID)
4. Make sure that you have DHCP active. Check the range of IP addresses it has in its pool and make sure there are at least 50 or so. For example, the range might go from 192.168.1.2 to 192.168.1.100.

I recently set my wireless internet up with a wireless WPA personal SSID. My printer connected to the wireless network without a problem. However, my nephew discovered my Wireless Key while watching Netflix one day and soon after I noticed that he had hooked up with his Laptop and Iphone everytime he came over. Since he would be able to get my wirelss key password off of the "wireless media" unit I have setup for Netflix. I decided to set up the MAC Filtering to allow only my 6 devices. I logged on to my linksys page and proceeded to "SEARCH WIRELESS MAC LIST" and found all of devices that were sharing the wireless network. I enabled MAC filtering and went ahead on logged each device on one by one. When I went to log the Printer on however I got an error message from the "WIRELESS NETWORK TEST REPORT"
reads as follows:
Your wireless router requires a WPA security passphrase. The passphrase configured on your HP printer does not match exactly . Run the wirelss network setup to re-enter your wireless network and WPA security passphrase***
This security passphrase is the same one that I am using to connect the other 5 devices so making an error in inputing the passphrase is not the problem. As i mentioned previously it worked with the wireless passphrase perfectly. Now that I have enabled MAC filtering it won't accept the wireless key. Can someone please help? Thanks in advance

coopydoop, "4789 fails to recognize the wireless connection". You will need to re-install your printer. Get the latest software for your printer from the "Support & Drivers" link at the top of this page.
help_intexas,
Is your printer on your MAC filtering list? If so, are you SURE it is the correct MAC address (not one begining with "HP")?
