I have a 3300 hooked up to a 964. I have my Netgear WGR614v6 setup like listed below. I have few problems, usually during an electrical storm or power flicker. I sometimes have to turn everything off for 15 seconds and then turn everything back on, that's all.

Try installing your printer like listed below.

Fix your network first.

Update the firmware in your wireless router. Manufacturer's website, make & Model needed.

Broadcast SSID(You may want to change this to make it easier to connect)

Use WPA security

Mixed b and g mode(n if available)

Use channels 1, 6 or 11. Most devices work better on these channels.

After router is done, now setup your wireless print server/printer.

If wireless printer server is used, Plug USB cable into computer and print server. Insert the print server disk. Choose Network, then choose print server and follow the instructions. If the disk does not work for Vista, you may have to go to drivers and downloads and download the 3300 drivers and install from that program.

Now setup the printer.

Now go to drivers and downloads/select product/printers/select your printer. Download drivers, Utilities, firmware and Patches. From what I see, the patch is to remove the printer.

Install your printer drivers. Choose Network. Follow instructions.

Everything should now work.

Is your wireless router set on channels 1, 6 or 11. Most devices work better on these channels.

Type of security?

Try un-installing the printer one more time and restart your computer.

Click on the downloaded drivers. Choose network. Noe click add printer. Now choose wireless print server. Follow the instructions.

What do you get?

Thanks for the suggestions. 

My router is on channel 6.  I have McAfee security. 

I reinstalled the 3300 and got network access OK. I uninstalled the 944 printer and downloaded the drivers again.  I selected the network option and then selected “The printer is connected directly to a network or wireless printer”. 

The installation went OK, including the last step of detecting the printer, but when I try to print, I get the message “Communication Not Available”.  I tried again with the firewalls turned off, but had the same result.
