Wireless doesn't work anymore: "Limited or no connectivity"

[Guest void.no.spam.com@gmail.com]

I have a Windows XP SP2 laptop, which connected to my network

wirelessly. It worked fine, until I uninstalled a bunch of apps that

I didn't need anymore, and then it stopped working. Whenever it tries

to connect to my wireless network now, it connects, but then it can't

get an IP address for some reason. It just says "Limited or no

connectivity."

 

The only thing I uninstalled that was related to wireless was

something called a "Venturi Client". I didn't think that was related

to wifi, I thought it was for a wireless modem that I used at a

previous job. Anyways, I'm using the built-in Windows Zero Wireless

utility, so nothing I uninstalled should have affected that.

 

Any ideas why it suddenly can't get an IP address?

It's definitely wireless-related: it's a wifi accelerator program.

It's definitely possible that it tied in with your wireless setup, and

didn't put things back together properly when you uninstalled it.

Get to the list of preferred wireless networks and delete the entry for

yours (and all others that you don't recognize). Then try to connect

again and be sure that you enter the encryption password correctly.

Yeah I deleted a bunch, and now have only 2 - my own, and a friend's

that I set to "on demand". Then I deleted my own, and re-created it,

and it still doesn't work.

This message occurs when your NIC is set to obtain an IP address

automatically but is not receiving an address from a DHCP server.

 

(You can check this by running ipconfig /all from a Command Prompt

window. You should see (about the 4th line down under your NIC's name)

"Dhcp Enabled: Yes" and the IP Address will be of the form 169.254.x.y)

 

In a wireless network, the usual cause is that the client (your

computer) has not properly authenticated to the access point (your

router) because of a security error. Eliminate this possibility by

(temporarily) removing *all* wireless security (encryption, MAC filters,

IP filters, etc.) using your router's configuration utility. While

you're in your router's configuration utility, double check that its

DHCP server is, in fact, on and set to allocate enough IP addresses to

accommodate your LAN. Go back and delete the entry for your network

from the list of preferred networks, because it will have a saved

password and thus won't connect to the now-unsecured wireless router.

 

If you still can't get a working connection, MVP Chuck has a page that

is a good starting point to continue your diagnosis:

http://networking.nitecruzr.net/2005/07/limited-or-no-connectivity.html

 

Given that you ran into this problem when you uninstalled things, I

would suspect an LSP/Winsock problem. See the link on Chuck's page

linked above for multiple suggestions on this, but for your first try,

I'd suggest:

 

netsh winsock reset catalog

 

from a Command Prompt window.

When I try that, I get a popup that says "Network Command Shell has

encountered a problem and needs to close." What do you make of that?

Assuming that you're logged on with administrator privileges, I don't

know what to make of that error message. Do you also get it if you just

try

"netsh /?" [without quotes]

 

Try the other methods suggested at PChuck's site.

Thank you for pointing out PChuck's site, Lem. The LSPFix detected a

problem in the chain, and it fixed it. Now I can connect and access

the Internet.

 

But if I do "netsh /?" from a command line, I still get the "Network

Command Shell has encountered a problem and needs to close" error.

How serious is that? Do you think some of the other fixes listed on

the PChuck site might fix that problem?
