Sigh...

My wireless router has stopped talking to my desktop.

But here's the weird thing. The wireless is fine--I can still access the internet and router through my laptop on that connection, but the desktop is plugged directly into the router via cable, and the router is refusing the connection. When I do an ipconfig, it shows no connection and no assigned IP address. When I unplug the cable, it knows it's unplugged, and when I plug it back in, all is well again, except it won't talk to the router.

I've tried rebooting the thing several times, with no luck. It just started happening, and I didn't do anything unusual that might have caused it.

Next thing to try is rebooting the desktop, I guess, which I hate to do because I have a loot of browser windows open that I'll lose.

Well, that did it. The ways of Microsoft passeth understanding.

Not sure if you tried this but this will sometimes help refresh your network connection without rebooting:

Go to Start > Run and type cmd and hit

At the command prompt type ipconfig -release windows will report an ip address of all zero's

Then, type ipconfig -renew and then hit this will cause windows go out and fetch a new IP from DHCP.

Also the same can be accomplished by going to Start > Network connections folder and then double click on your network adapter. Click on the support tab (which will display the same information as ipconfig) and then click on the repair button (which does the same as an ipconfig release and renew).

Note: that I had recently added a computer to my wireless network and due to poor connection quality my router would often have similar types of issues that you've described. However, I recently took 15 minutes out of my life and constructed a parabolic dish from cardboard and aluminum foil with very good results. My router issues have dropped to zero since this recent enhancement. For more details try this site:

I'll try the "renew" thing next time, but note that this was not a wireless problem. My wireless connection was fine on my laptop. The desktop was unable to communicate through the ethernet cable.

The IPconfig /release and IPconfig /renew will work with any network connection...so it will work with your Desktop NIC.

Correct. When I introduced a computer into my network that was experiencing poor signal quality and began to experience daily issues with my router ranging from complete lockups that took my whole network down. To knocking my wired ethernet computers off the network while wireless connections were maintained. To the whelp from my girlfriend on the wireless computer in the other room saying, "The computer lost connection again!!!"

I added my parabolic dish to the antennae of my router and have maintained an uptime of roughly 3 1/2 weeks so far with no issue.

I took a call from a client earlier today who was in a fab area and his computer would blue screen, memory dump, and then reboot itself when he would make a call through outlook to the global address list. I asked him to look at his signal strength for his wireless connection and it was low. I had him wonder around the facility to a point where the signal strength was strong and had him make a call to the directory lookup and had no issue. Corrupt packets can cause some nasty things to happen. There are even some viruses out there that corrupt network packets on purpose to cause routers to crash.

the disable/enable thingy often works too with such issues, you just gotta remember not to do it over remote desktop connection :/

Lose lots of browser windows on shutdown? How? I mean, all you have to do is select "start with previous windows" when Opera fires up.

Windows Troubleshooting

1. Reboot.
2. Reinstall.
3. Reformat.
4. Profit!

I have a Linksys router which sometimes shows the same symptoms - DHCP works fine with wireless laptop connection but not with the wired connections. I finally gave up and just assigned static IP addresses to wired connections; this works ok as long as my ISP doesn't change the addresses of the DNS servers.

If you ever figure out what the problem is, please post it!
