I'm having a frustrating and what seems strange trouble, i'm hoping it's a quick fix, maybe something I've overlooked. I currently am running XP, SP3, and an older Netgear G router. I got a new D-link N router for Christmas. I'm now having some issues on the replacement. I can not get network connectivity. The router install went smooth, but said at the end that it couldn't detect my internet connection. Well, I know my internet works since I was fine before the swap, so it's not my ISP. After a while troubleshooting, I decided to connect directly from my Comcast broadband modem to my PC's lan card. That's where I get the Acquiring Network Address, times out, and then I get the Limited or no Connectivity error. So at this point, I've eliminated the router and any wireless configs as an issue. Ipconfig shows the 164.x.x.x address and no gateway address.
Now here's what's strange to me...if I connect my old Netgear back up I'm back in business. And both the direct connect from the netgear router to the Lan card and wireless connections work. Ipconfig with Netgear shows IP address of 18.104.22.168, 255.255.255.0 subnet mask, 192.168.0.1 gateway and dns. All of my TCP/IP settings are set for automatically finding an ip address, no static or manual ones. But if I remove the Netgear and connect the PC lan card back to the modem directly, it's a no go. I've disabled wireless network connection to remove that from the equation. I've retried everything with different cables, and they aren't an issue. I just don't know why I'm not getting connectivity straight from the modem to the PC, but yet it works with the wireless router. Is there a setting somewhere that I need to change? Is there something that I've set that my network will only work with the Netgear device as the gateway or something? I'm at a standstill right now.
Thanks in advance for any help!
