Hey DonnyJ.
Can you see the wireless network from your notebook? If you can great. If you cannot see the wireless network at all, here are some thoughts:
1. Are you using the defaults on the wireless router? (don't answer directly, could get hacked - MAKE SURE the password is changed if nothing else).
2. Do you have another LinkSys router/gateway on you network using the defaults? If so, you have a conflict.
3. Are you connected to a DSL or High-speed connection? May have DHCP enabled on these devices causing conflict.
4. Do you have another DHCP server on your network? If so, you will need to disable one. I made the wireless router a DHCP client on the WAN side and a master on the LAN side.
5. Is the firewall enabled?
6. Using MAC address filtering?
7. What security mode are you using?
8. What mode are you using? (ad hoc, computer-to-computer, etc.)
Try plugging a network cable into your laptop - or another computer if you have a port and make sure you can see the network. Believe your wrt54g has (4) port hard connections on the back. Doing this will verify that the router is good and the issue is related to the wireless.
If you can see the network from your wireless on the laptop, and you are sure the printer is shared from your computer where the printer is attached you need to add the printer on the laptop. Got to settings->printers->add printers-> and select "add a printer". You will have to add it as a directory on the printer in the form of \\PC name\printer name.
Hope this will help or get you started. Let us know how it goes.
