Wireless IP Configuration

Hi,

I have just upgraded from Windows Vista to Windows 7 recently but currently I'm face with a problem.

After connecting with the wireless net at home, I have no internet access. It says "Wireless network connection doesn't have a valid IP configuration".

I read on websites that I should change the TCP/IPv6 and TCP/IPv4 to automatically acquiring IP address and DNS server address, but to no avail. I tried using the CMD but don't really understand how the IPCONFIG/ALL and IPCONFIG/FLUSHDNS work. I also tried changing the last 3 digits of the IP address to a higher number but also to no avail.

Done all that I could do, but I still can't access to internet though I could connect to the wireless.

Can anyone help? Your effort is much appreciated. =)

Hi and welcome

couple of things to try
Are you using a firewall or antivirus? disable them to test
use the ipconfigs like this first ipconfig /flushdns then ipconfig/renew
in cmd type ping and the routers ip

let us know results

Hi, first of all did you changed the SSD name? Do you have password ? Did you tried without pass??? Can you login in router ??? What system do you have ??? What router do you have ??? Don't mess with cmd, it's useless... Disabling/enabling the wireless network adapter is just enough... did you updated the driver ??? Try updating with manufacturer drivers... not the one from windows update.... And post more info about your system...

I turn the Public and private firewall off, disconnect and connect again but still can't get the internet access.

Then the ipconfig/renew, there was an error saying: An error occurred while renewing interface Wireless Network Connection - The operation was canceled b the user.
And: An error occurred while releasing interface Loopback Pseudo-Interface - the system cannot find the file specified.

Then I ping the IP address: 4 sent, 0 received -> 100% loss.

Anyway this is the wireless adapter I'm using: Atheros AR928X Wireless Network Adaptor. The driver (though I don't know what is it) is updated using the Windows Update.

Hi, sorry but I'm not very tech savvy. Initially when I bought the laptop, I could just on the wireless and get connected easily without much problem. The problem only occurred when I installed Windows 7.

As it's wireless from my home, I have the password to the wireless. What do you mean what system do I have? This?

Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz
4.00GB RAM
32-bit Operating system

I'm using Buffalo Inc. router, Motorola modem? Is this what you're asking for?

How do I update with manufacturer drivers?

Sorry for your issue, couple things to I need to know:
When you were using vista, did you have to use static ip as well? Not sure how old your router is, but some routers can't handle the dhcp broad cast flag (this happens for vista, I am sure the same goes for w7). To handle the flag issue you have to do some registry editing. We will get to that, if necessary.
I assume you are using the drivers assigned by windows. If so, you should get the drivers from your manufacturer's website, and update the drivers with theirs.
You may run into the issue where it may not let you update the drivers by telling that the latest one is already installed. Use this method to update the driver:
Device Manager, the Wireless Card, Update Driver, Browse computer, pick from a list, Have Disk, then locate the unpacked folder with your drivers. if there is isnt a w764, try the xp64 driver.

Oh man all these look Greek to me. I'm not sure whether was it static IP address or not, but I assume so.

The card I'm using (which I found under PCMCIA adapters) is O2Micro OZ711SP1 MemoryCardBus Controller. Is it this card? If I were to update the driver manually, does it mean I have to download or buy something? Manufacturer's website as in Fujitsu website? My laptop is Fujitsu.

The card you using is under Network Adapters... What about visiting the manufacturer site of your laptop and downloading the drivers for windows seven...

Alright, I'll try and get back to you soon.

Hi, I went to the Fujitsu Driver website and downloaded the driver there. Using a thumbdrive, I install the new driver onto my laptop but still, I could not get the internet access. I could get connected to school network too, just can't access the internet.

I'm using Windows 7 32bit software.

Thanks.

I had this issue whilst connecting directly to my router, the machine wasn't able to obtain any IP settings from ISP's DHCP. Turns out i had issue with the router's MAC cloning setting. Not sure if this is the same issue, can you provide ipconfig /all details.

This? This looks greek to me anyway.

Anyway this guy seems to have the same problem with me. Regarding the 'Unidentified Network' and 'No Internet Access'

Don't worry man... Greek Looks Greek to the Greeks....


yeah i can already tell that your card is not pulling a proper IP address.

Help us out here.

We need model and make numbers of:
Your Router
Your Desktop
Your Laptop

Also, what version security you are using.

how do you have your router set up. did you just pull it out of the box plugged wires in it like the big sheet told you to do and left it alone?

Somehow I don't think it's the problem with the router as I never have problem when my laptop is still on Windows Vista. Furthermore, there is no way I can do anything with the school network, given the fact that I face the same issue while at home and at school.

Why doesn't it pull the proper IP address?

The reason why its not pulling a proper IP is becuase your network is not configured correctly. I know that it sounds like a redundent answer but its the truth.

The reason why i need your router is because some routers are not compatible with windows 7. I just need to make sure. thats all.

If i have your computer model. I actually know what is being loaded with windows because it tells me when i pull up the computer on the internet.

If i have your security system I can tell you how to configure it. I may be good at computers but i don have a artistic memory of remembering screen shots of different antivirus and firewall programs.

Hmm, it's Fujitsu Lifebook S Series S6421.

Okay I realized something new, that the Norman Security Suite (the antivirus softwar) has some compatibility problem with Windows 7. And somehow I can't seem to run it because it doesn't have network connection.

How about your router....
make i have the make and model please


i would delete that anti virus and use this one.

everyone seems to love this one and its free

This shows me that you do not have tcp/ip4 network connectivity. Before you can attempt to connect to your wireless network, which is broadcasted by your router, you need to make sure your wireless adapter is working property. Go to your Atheros AR928X Wireless Network Adapter, in device manager. Under Properties, is tcp/ip4 ticked?

Can you screen shot this?

I can screenshot but I don't know how to post the picture here. Anyway, it's under the Wireless Network Connection Properties where I find the TCP/IPv6 and TCP/IPv4, both are ticked. Everything in that page are also ticked.

My Router is Buffalo Airstation, Model: WHR-G54S.
The modem is Motorola SURFboard SB5101.

Yupyup.

Is your "WLAN autoconfig" service in Services.msc started?
