I cannot find the setup CD of my Linksys WAP54G Access Point, and I cannot configure it properly again. For some reason it is not working.

Go to this web site and download your setup.

Hey !
you said that you that you reset the WAP54G , the default IP address address of WAP is 192.168.1.245.
The IP address that you tried ( 192.168.1.1 ) must be the IP addres of the sonic firewall which might be acting as a DHCP server.
To access the WAP54G set up. you will need to connect the computer to the HUB and the WPA to the hub with the cable and then try to access WPA with the IP address 192.168.1.245

If the power lost power for at least an hour it loses its entire configuration. There is no current fix for this that I know of

check this out and i hope this will solve ur concern..

Open any browser in Vista:
Type 192.168.1.1

your pc firewall is enable? diseable it and check the cable

the ip address of the 2wire router might be different from the ip address being used by the wap54g (ip address is 192.168.1.245 by default) that's why it's not being detected.
you need to directly connect the wap54g to a computer and set the computer to use a static ip address (ex. 192.168.1.240) and run the cd that came with the wap54g. you need to set the ip address of the wap54g to the same segment being used by your router to make them see each other

hope this'll help you and just ask me if you have other concern

ciao!

perhaps this can help you

The IP Address of WAP54G is 192.168.1.245

Connect a computer to the Access point.

Assign a static IP Address to the computer, like : 192.168.1.10 , the subnet mask should be 255.255.255.0

Open the setup page of the Access point, by typing 192.168.1.245 in Internet Explorer / Firefox. Configure the wireless settings, Change the IP Address to the range that of the Actiontek router.

Save settings. To know about wireless security, click here.

Ok, so why do you need an access point upstairs and a router downstairs connected wirelessly? If you can't connect with a laptop or a pc, why whould you think you could connect the access point? The purpose of this configuration would have to be with the access point to the router via ethernet. What's the point? If the problem is range, check out http://www.dd-wrt.com/dd-wrtv2/index.php to enhance the capabilities of the WRT54G... and maybe building a parabolic antenna for it as well. Plans to do so abound at Lifehacker.com.
