Help! Getting an IP address but NO interntet connection.

Hi. I have a Linksys WRT54GS router and a Motorola SB4100 Cable Modem. I'm trying to set up a network so that all of my computers can connect to the internet.

If I connect the SB4100 modem directly to a single PC, the internet is working fine. But if I will connect the SB4100 modem to the Internet port of the router and after cloning the MAC address of the LAN adapter of my PC to the router, i do not get internet connection at all.

the weird thing is that the router status have all i need to connect to the internet. i get the domain name of my isp, my ip address on the internet usually like (210.xxx.xxx.xxx) (not the 192.168.xxx.xxx), a default gateway and 2 DNSs. they are the same information i get when i connect directly from modem to PC that runs smoothly. Though i get these numbers, i cannot ping the Two DNS the router gives me. That is very weird. These is the status of my router.

on my computer, i get the usual 192.168.xxx.xxx from my router, the default gateway ip address of the router, etc. it seems that everything is fine. i can ping 192.168.1.1, enter the browser and configure the router.

am i missing something? please suggest all the necessary steps to solve this problem bec. i beginning to explode just figuring this one out. Thank you very much in advance.

Any firewall software running on the PCs? What operating system are you running, what ISP do you use and do you specify a proxy within your browser connection settings?

i already turned off the firewall of my pc. i am using windows XP SP2 and my ISP is comclark surestream (Philippines) and it also does not specify a proxy.

Try resetting the router back to factory defaults...?

problem resolved! it turns out that the problem is the modem not communicating to the router properly. so i went to my ISP and have them change my modem. then after setting my home network again, all is working good. anyway, thanks for all your suggestions.
