Linksys WAP54g v3.1.Can't connect more than 1 computer wirelessly

Try reseting the Linksys back to the default settings - Press and hold the pinhole RESET button at the back of therouter with the power ON for 20 secs. then release the RESET button.
To connect to your wireless router, the router's wireless settings needs to beconfigured with the SSID, encryption etc. and also the wireless cards in allthe laptops/computers needs to be configured with these router's wirelesssettings. Then the laptops/desktop computers can communicate with your wirelessrouter.
Connect a LAN cable from the Linksys to the LAN port on your computer.
Open a browser and enter the Linksys configuration URL
http://192.168.1.1
The default login = admin
The default PW = admin
You can protect your router by changing the default PW (write it down and putit in a safe place)
Go to the wireless configuration and set up the SSID and WPA or WPA2encryption.
Apply these settings to the wireless card in your laptop/computer.

try to reset your AP please.

Ok, what you really want to do is have one router as an access point and the others all set as repeaters.
You'll want to find some WAP54G for the access point/repeaters
The procedure, I cannot explain better than this article does:
http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&login=1&app=search&vw=1&articleid=4200
it has diagrams and the works on setting those routers into repeater mode.
Post a comment here if you have any issues with that configuration!
NOTE: your configuration should use 2-3 WAP54G with a WRT54G as your main router at the modem.

You must be more PRECIS with your question... What I understand is that you want to connect two computers to the WAP54G (wireless Access Point)??? an than you mention wires ??? if it's because the Access Point is set up to bridge with an other wireless network you can not hard wire two computers to the AP (since it has only one port) unless you have a multi port SWITCH staked/connected to the AP, if the AP is set up to broadcast a WIFI connection than you just need to set up the second computer with the same information as the one all ready working (SSID, ENCHRYPTION KEY, etc...) if it's because you are trying to NAT one computer connected to the AP to an other computer through hard wire, than you need a switch and a good understanding of networking to share a single network connection with two computers...

Try the following steps:

1. Disconnect the WAP54G power adapter.

2. Reinsert the power adapter directly into the wall socket.

3.Remove any power strips or surge protectors temporarily to ensure that these items are not preventing the WAP54G proper operation.Note: Make sure that you are using the power adapter that came with your WAP54G.

4. Plug the power adapter into a different wall socket in another room.

5. Press and hold the reset button for 1 minute. Release the button. Then turn off the WAP54G for another minute. Then turn it back on.

6. If the power light is still red, then you will need to replace the WAP54G.

You need to get a router in order to share the Internet connection. The existing Internet connection (from the DSL/cable modem for instance) goes into the WAN port of the router/firewall, then you connect the AP to one of the LAN ports.

Today it is often a better idea to buy a wireless router instead, i.e a router with built-in wireless AP. They are very inexpensive.

yes, the manufacturer doesn't really matter as long as they are 802.11g (usually backwards compatible with a and b) so as long as the router and the adapters are installed properly NO problem

Unfortunately cyber this does not have a mode or option to act as a repeater .I have check their website and check the specification of the device..You may want to get the WAP54g from Linksys as well for it has that option (act as a wireless repeater) or get the WRE54G wireless extender or repater for Linksys router.

Hope this was informative.

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.
