I have a Dell Inspiron 9400 with an Intel PRO/Wireless 3945ABG card. I am using a D-Link DI-624 router to create a wireless connection.
The router was working perfectly fine untill I did a PC Restore in my Dell laptop. I am able to access internet using an ethernet cable directly between my cable modem and the laptop. However, when I connect the modem cable to the WAN port in the router the wireless card will not detect the router. Also, if I connect the router to my laptop using a separate ethernet cable the Network connections inside the Control Panel will show both Local Area and Wireless connection as "Not Connected".
I have tried resetting the Modem and the Router but it won't help. I have also spoken to Dell Wireless Support, D-Link support, Comcast support but none of them are able to provide a solution.
While talking to the D-Link support I was resetting the router and after that I found that the Status LED stopped showing up. All other lights (Power, WAN and LAN)come up fine. The Status LED was showing earlier. I tried to reset the router a number of times but the Status LED is still not showing.
Any guess why is it happening and what do I need to do set up a wireless connection using this router.

Re: Unable to detect my router
This is because your router is setting your pc at a different IP address than your original modem.
Make sure router is set to enable DHCP which gives out an automatic ip address and check your wireless card and network cards are set to obtain ip address automatically.
It may take a few re-starts to get on the internet as your systems will need to clear their previous DNS settings.
Also i assume you have set up the home network wizard (XP) as you are now using a router and not a direct modem.
Also try Start>Run, then type ipconfig /flushdns then press enter.

I had usualy solved mysterious problems with other intel PRO wireless cards not authenticating, loosing signal, etc, by simply upgrading to the latest intel drivers. Also using the Intel connection manager instead of the windows or Dell/other notebook manfucaturer's product is far more reliable. Hope this helps.
from what you say, it sounds as if you have your wired and wireless card connected at the same time.
This will confuse the router as it is trying to give two different ip addresses to the one pc, which it cannot do.
If you are using the wireless adapter, make sure you dissable the wired adapter as the router will continually look for the wired ip address while allocating your wireless adapter causing instability.
Next ensure you have a good clear signal from router to notebook as this can obviously cause problems.
Lastly ensure that the wireless cards TCP/IP properties are set to obtain ip address automatically, especially if your router is DHCP enabled to allocate ip addresses automatically.
This is unusual, as it seems the router is allocating two pc's the same IP address.
Go into your routers settings (internet browser and type the router address, eg 192.168.1.1)' and look at Client DHCP list and look at the IP addresses that each pc has been given and see if two are the same, they should be one digit difference, that being the last.
Also go into the properties of both your pc's wireless cards and ensure that they are set to obtain an ip address automatically.
