Hello. I am experiencing a problem that baffles me. The bottom line is I cannot get a laptop heard on the Internet even though I know it is seen. My ISP is a cable provider. I have a WRT54G (firmware v3.03.6). I have 3 laptops. Two laptops are XP and the third is W2K. The modem is a Motorola (model=?). About 2 weeks ago, I purchased the WRT54G. Upgrading from my older Netgear, I was looking forward to being able to VPN into my work with my wife also VPN'ing (which I could not do on the Netgear). All was fine for a few days when I noticed that the XP laptops (my personal and my work machines) were unable to get to the Internet but my wife's W2K laptop was just fine. As far as the ISP was concerned, all was fine since they saw the modem. Further investigation showed that although the XP boxes were given an IP address, they were not given DNS addresses. I bypassed the router and saw the same behavior. The W2K laptop was fine but the two XP boxes were without DNS addresses. The ISP gave me a new Motorola modem to replace the one I had and whaddaya know, the behavior is somewhat swapped. Now, the two XP machines are fine, off the router and wired/wireless but the W2K does not work off the router (wired or wireless). It will work directly off the modem but that's no way to operate. I use IPCONFIG to tell me IP and DNS address status. Can anyone provide me with some guidance as to what the problem is? Why would a machine not have a DNS address but yet have an IP address? Thanks in advance. ps - The W2K laptop has no local firewall running, at least that I see (no ZoneAlarm, Norton, etc). And when I could not get the XP machines running, I shut down ZoneAlarm and XP firewall to no avail.
