I have a PC that uses 3G USB modem to surf the Internet. Now I want to use my WRT54G as the access point and DHCP so that I can share my Internet with others at home.

I've seen a lot of sites on how to convert WRT54 to become an access point, but I've yet to find a solution that suit my need

this is the type of connection that AP will take
I don't think that AP can work as AP except the new one

In this case, why dun you disable the DHCP on the linksys. Just connect your network cable to the LAN port instead of the WAN port.

I would presume that your PC is also connected to the LAN port. In addition, you are also doing ICS on your PC right? So DHCP will be given by the computer. You must turn off the DHCP on the linksys as it will make all computers attached to it to a different gateway.

Ooooh!!! How do u know that I am from Kuching?..... Scary?!!! Ha ha ha !!! Yes.

Alternatively, its to put the WAN port on fixed IP and then make the DHCP on the linksys work. Then u will have 2 sets of network.

TCM, how do I configure the fixed IP option? As shown on the image, what IP address should i put in the static IP config? Will it be my USD modem IP or the IP of the PC connected to the USB modem.

nvm, i got it working eventually. I used the same way as what many sites suggested. I don't know why, but it won't take 192.168.1.1 as the gateway ip. thanks anyway guys..
