"Media Disconnected" with wired router connection
I'm hoping someone here can help me fix my Ethernet connection to my router so I can configure it for wi-fi. Let me start by giving you the full background story.

I have a US Robotics 5462 router and a D-Link DCM-202 cable modem on Comcast. I've had this router for years and initially configured it for wireless access using a Windows XP system (this router requires you to configure it via Ethernet and 192.168.2.1). That computer stopped working last year, so I got a new computer running Windows 7.

When I first got this new PC, I could not connect to my router via Ethernet (just like I can't now), but I was still able to connect to the wireless network I had previously set up, so I was satisfied. A year went by, and last week I was suddenly unable to access my wireless network, so I did a factory reset on the router, erasing my previously configured wireless network and requiring me to connect the router to my computer via Ethernet to reconfigure the router. I tried to do this, but despite all of the correct LEDs being lit on the router, I could not access 192.168.2.1. A little poking around on my control panel revealed that my LAN was being labeled as an "Unidentified Network" and there was "No Internet Access." I tried to make it a private network, but that didn't fix the issue.

I searched around for a while and read some advice to try running ipconfig. When I did that, I saw "Media Disconnected" for my LAN adapter. Googling that brought me here. I've tried a few of the possible solutions already with no luck.

It might be helpful to know that with the same computer and the same Ethernet cable directly connected to my modem instead of through the router, I *CAN* get online. That's how I'm connected right now. Also, I have no problem accessing any wi-fi networks.

Please let me know which commands you'd like me to run and post so you can help me out. Thanks in advance!

the ip addres you have posted looks like its connected to the modem

User manual
http://www.usr.com/support/product-t....asp?prod=5462


connect to the router and make sure the router is not connected to the modem
do another full reset on the router using the reset at the back of the route
Quote:
If your Web User Interface stops responding, unplug and then plug back in the power supply of
the 802.11g 54Mbps Router. This will reboot the 802.11g 54Mbps Router. If you are still unable to
communicate with the router’s Web User Interface, use a paperclip to press in and hold the RESET
button for five seconds. This will reset the 802.11g 54Mbps Router to the factory default settings.
If you applied any personal configuration settings, you will need to make the changes again.
now do the following
Quote:
Launch a Web browser. In the location or address line of your Web browser, type
http://192.168.2.1 to access the Web User Interface.
After the connection is established, you will see the Web User Interface. The default password is admin. Click Login

Thanks for the reply. I just followed your instructions (connected to the router without the router connected to the modem and tried to access 192.168.2.1), and I was still unable to get there. I tried it once without rebooting my laptop, once after rebooting, and then once after reconnecting my router back to my modem. No dice. Also turned off my firewall in case that makes a difference.

With my router NOT connected to my modem and after a full reset and a laptop reboot, this is what I get when I use the same commands as I posted earlier:

So it gave me a different ipv4 address, which it's now able to ping, but now it doesn't give me a default gateway. What does that mean?

Hmm, something interesting just happened. I tried resetting a few more times, and one of those times, my old wi-fi SSID somehow came back from the dead and started broadcasting. I wasn't connected to the cable modem, so I had no internet access, but I was briefly able to reach the configuration utility at 192.168.2.1. However, as soon as I connected it back to the cable modem, I lost that access. Additionally, I'm not convinced my attempts at doing a factory reset are actually resetting anything. I'm using a paper clip to press the button on the back of my router for 5-10 sec, and something is definitely pressing, but the LEDs don't change at all unless I unplug it.

So I'm thinking my router is bricked. Any other ideas?

I agree that it sounds like a failed router. But unless you are sure that 10 seconds is enough for your router hold that reset button for 15 to 20 seconds.
