XP can't ping router?

[Guest]

This is a bit long, so I apologize, but I am at a complete loss! Nutshell situation: added a new harddrive to my computer, chkdsk ran on original dirve, and deleted system files. Had to do a complete new install of Win XP Pro. The problems begin.
1. I have a DLink DI704P router connected to a wireless access point and DSL modem. The wireless network works fine.
2. This computer is being assigned an IP/DSN by the router (192.168.0.1), subnet 255.255.255.0.
3. I cannot ping router from this computer (timeout error).
4. I can ping this computer address (local loop?) and everything is fine (192.168.0.102 assigned by DHCP).
5. I have reset the TCP/IP stack using the NETSH command.
6. I have purged the ARP using NETSH.
7. I have reinstalled Windows on the origianl drive, same problem.
8. I have installed Windows fresh on the new drive, same problem.
9. I have updated NIC drivers, same problem.
10. I have replaced the NIC board with new one, same problem.
11. I have moved NIC to new PCI slot, same problem.
12. I have tested cable and router connection on another computer and it works fine.
13. Wireless network works fine on all other computers, can see this computer, but cannot access it (no permissions error).
14. I've lost reasonable sanity over this.

Any help anyone can give is appreciated. This computer has been working for 2 years on the network, no problems, until now. The only thing I noticed is that I had a network bridge before in Network connections, although I do not know what it was bridging? Now I cannot install a bridge because I only have one NIC.

Many thanks in advance.

Don't some routers have an option not to respond to ping?

The only thing I noticed is that I had a network bridge before in Network

connections, although I do not know what it was bridging? Now I cannot
install a bridge because I only have one NIC.

I've only ever had one NIC installed and I managed to get a bridge to appear
by using the wrong option in the WinXP Network setup wizard - the bridge
stopped everything working!

Which option did you choose when you ran the wizard? After many problems I
decided that the best option to choose (if you have a router) is the option
"I connect using a hub". You get a security warning that says hubs aren't
safe but a Router is like a hub with a firewall added so it should be OK.
Why Microsoft didn't include an "I connect using a Router" option I never
know. Perhaps they have now?

PINGs are blocked from the WAN side, not the LAN side!
