Hi,

My 3G modem doesn't work. Windows diagnosis tool says "Local area connection doesn't have a valid IP configuration". "Netsh winsock reset" command works, but only until I connect with my wifi. Then it starts again.

Hey fred7790,

Have you contacted your service provider? The difficulty with troubleshooting wireless modems is that they contain their own proprietary software.

If you can still connect and transfer data through your normal connection, it is unlikely to be a WinSock problem.

Regards

Laz

Hi, fred7790
Any update?

What OS are you using?

If you open a command prompt you can check your IP config like so:

ipconfig /all

Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . : <domain>
        Description . . . . . . . . . . . : Intel(R) 82567LM-3 Gigabit Network Connection
        Physical Address. . . . . . . . . : FF-23-24-14-F0-C3
        Dhcp Enabled. . . . . . . . . . . : Yes
        Autoconfiguration Enabled . . . . : Yes
        IP Address. . . . . . . . . . . . :[if this starts with 169 then you have a DHCP problem]
        Subnet Mask . . . . . . . . . . . : 255.255.0.0
        Default Gateway . . . . . . . . . : 
        DHCP Server . . . . . . . . . . . : 
        DNS Servers . . . . . . . . . . . : 
                                            
        Lease Obtained. . . . . . . . . . : November 4, 2014 07:45:39
        Lease Expires . . . . . . . . . . : November 4, 2014 15:45:39

The output will be similar to the above
Check the IP Address.
If your system uses DHCP, and you get an address that starts with 169, then you aren't receiving the address properly.

Let me know...

PS: I'll move this to the computer forum

Thank you for help. I use Windows 8.1. It does start with 169, it's not called "IP Address", but "Autoconfiguration IPv4 Address" and after the address there is "(prefered)".

Hi, fred7790,
I'm not a Windows 8 adept, however, the Autoconfiguration thing has been around since W2K. It is there to provide a valid IP address so that some network-dependent programs don't fail outright. They don't work, but at least they do not throw up ugly error messages.

Try this:
In the same window as you typed
ipconfig /all

type
ipconfig /release

Then after a delay of 30 seconds or so type:
ipconfig /renew

If that works, great.
If not let us know.

Do you know where your IP address comes from? It could come from your ISP, a router or a Wireless access device.

Cheers,
VS

When I typed ipconfig/release it said "an error occurred: the parameter is incorrect".
And I don't know where my comes is from.

There needs to be a space before /release.

If there actually was one, then what to try next depends on how your network is set up.
  If your computer connects directly to you ISP, then call their support
  If your computer connects directly to a box supplied by your ISP, reboot that box
  If there is more than one device, start with the one to which your ISP's cable connects and reboot it. Once it is stable, reboot each other device in turn.

Best of luck,
VS

Rebooting the box didn't work, but thanks for trying. I'll contact the support.
