Wireless network magic?

Why is my wireless network WORKING?

I have a strange problem/non-problem that's driving me batty. My wireless networking is working without a problem. But ipconfig suggests that it shouldn't be. When I type ipconfig, I get "A device attached to the network is not functioning." But I do have an IP address that shows in Network Connections and I can access the internet no problem.

This whole thing started when I tried to install a Linksys bridge/retransmitter to extend the range of the network (I know, I know, bad idea). After that disaster, I had to re-install XP from scratch. I have an Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter on a Thinkpad. I am using a Netgear device that is a cable modem/wireless router in one (at the insistance of the cable company) with WEP (my roommate will not upgrade to WPA). I have the correct WEP key. After trying to install the bridge, the cable company had to come out to get everything working again.

I have updated my drivers. I have checked that Winsock is not corrupted using the instructions at www.howtonetworking.com. I have tried ipconfig /all, ipconfig /renew, and other variants. I have used netsh to reset TCP/IP. Sometimes, when I try ipconfig, my connection *stops* working, but if I turn the wireless radio off and on and reboot, it starts working fine again.

This might sound really stupid to pursue, because I am not having any obvious problem, but I really want to know why ipconfig is not working and how to fix it. Any ideas?

Is it possible that the error you are seeing is in reference to your ethernet card, not your wireless network? Barring that, is the IP address you have being dynamically assigned or is it static? Ipconfig will occasionally take issue with trying to renew a static IP address.

Also, rather than doing an ipconfig /renew, try going into your Network Connections folder and when you right click on Wireless Network Connection, it should give you the option to repair. This is similar to /renew, except that is also does some other maintenance like flushing your DNS.

Generally speaking, this is not something that you would ordinarily do with a wireless connection. (It's really more for when you are using ethernet), the IP is renewed when the wireless network connection is established.

If that was true, wouldn't I expect to see an IP for the wireless even if there is an ethernet problem? I do have a dynamic IP.

I have tried this, unfortunately.

Please more ideas!

Why don't you post your ipconfig /all command output here? Currently I'm surfing from an Internet cafe, and mine (formatted with the [pre] tag) looks like this:

You can see that my wired Ethernet port is currently disconnected, and my Wireless card is my current IP connection. How does your ipconfig /all output compare to this?

Easy way to do this if your ipconfig scrolls out of your command prompt window: IPCONFIG /all >c:\ipconfig.txt

You can then copy paste the contents of ipconfig.txt

Here is the entirety of the response when I ipconfig:

-----
Windows IP Configuration

An internal error occurred: A device attached to the system is not functioning.

Please contact Microsoft Product Support Services for further help.

Additional information: Unknown media status code.

Any suggestions for my next step?

I'd go to device manager and remove/reinstall your wifi adapter. Hopefully that will clear up the weird errors you are getting.

I don't get why installing a bridge/repeater would make you have to reinstall XP.

You sure theres nothing wrong with your wifi adapter?

This might help:

go to run -> services.msc

when that comes up make sure the following two services are started:

Remote procedure call (RPC)
Routing and Remote Access

Then try Ipconfig again.

Routing and Remote Access

That was it! That service was disabled.

Yay quin! Yay mefi!
