rickw001,
So you did have this working before using the Linksys router. I think you'll need to reinstall everything in order to get this working. There is a way to change just the ip address but I really don't think it will work as you're using a dirrerent router with a different Mac address and communications will be next to impossible and you'll tear the hair out of your head.
These instructions are a little lenghty. Please follow the instructions in the order that I have them and you should be able to setup everything to work. I do have a 964 printer connected to a Dell Wireless Printer Adapter 3300 and have it working for 5 laptops.
Let's make sure your computer has the latest Windows Updates, especially .net framework, needed to run many applications and the latest Java.
Fix your wireless router 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-PSK(TKIP) Security(WPA Personal). Most wireless devices work best with this type of security.
Mixed b and g mode(n if available)
Use channels 1 or 11. Most devices work better on these channels. (I use channel 11)
Save and exit. Power everything off for 30 seconds. Power everything back on, wait 30 seconds, now try to connect.
After router is done, now setup your wireless print server/printer.
3300 Utility
3300 Firmware
Attach the 3300 to your computer using the USB Cable and insert the 3300 disk. Follow the instructions. It should ask you for the network ID, type of security and password.
Now for the printer. Download and run this patch to completely remove the printer from your computer. Run the patch, a MUST on Vista machines, until it prompts you to restart your computer.
Restart your computer.
Download the proper drivers.
XP Drivers
Vista 32-bit Drivers
Vista 64-bit Drivers
All other drivers
Install the drivers, choose network, choose I'm using a wireless print server(if you do not see this, then choose add printer and you should see it then) and follow the instructions.
***When installing the drivers, the file might just unzip. If this happens, right click on the setup.exe file, then left click run as administrator, then follow the instructions***
As for scanning, if you have the disk that came with the printer, then insert the Printer disk and stop it from running. Go to My Computer and double click on it. Look for the drive with the Dell disk in it. Right click on it, left click explore. Look for the OCR Folder. In the OCR Folder, there is an Abbyy Folder. right click on setup.exe, that's in the Abbyy Folder and left click run as administrator. This will install the OCR program.
Scanning
Scanning using USB connection, open the Dell All-In-One Center, click on scanning and copying and scan from there.
Scanning wirelessly, use the scan buttons on the printer
Let me know what happens.
