Windows 7: Wireless Network Connection doesn't have a valid IP configuration

Wireless Network Connection doesn't have a valid IP configuration

Hello there dear friends.

I just registered to your forum searching for help to a very persistent and annoying problem i have been facing.

While my internet works fine, many times a day (every day) the connection will fail and a yellow exclamation pyramid will appear at my connection status. When i perform a troubleshoot at my connection the problem is recognized as Wireless Network Connection doesn't have a valid IP configuration and the problem is immediately repaired.

Now as you understand this is a very annoying problem because i am unable to perform many internet functions demanding time as downloading a file or playing an online game because i will drop every once and a while. I noticed that many people have been facing this problem but they couldent connect at all in the internet, as you understand my problem differs because i can connect to the internet but i get dropped every once and a while.

I am using a wireless router: airties rt-205
my laptops network card is a realtek rtl8191se
and i am using windows 7 home premium 32bit.

Before you ask i have already updated my networks card and routers drivers to the latest ones.

I beg you masterminds of windows 7 forums please help me solve this very annoying problem thats killing all the fun of my internet.

(ps if you need the details of the troubleshoot report just let me know)

Hi BlitzGreek, welcome to the forums

My next door neighbour had the same issues but it turned out to be a fault with the router. You could try 1 thing...Turn the router off, press and hold the reset button (found on the back of the router) for 5-10 seconds then power on again.

Note   Note
This will completely reset the router to factory settings without reverting to previous firmware. It can take up to 2 minutes for the connection to be fully restored.

ISP's tend to send router updates up the line but this can cause connectivity issues

Hope it helps

Have you tried scanning the area to see if you are using a clear wireless channel?

It would be worth while to run the Xirrus wifi inspector to make sure you are using a clear channel. You can change the channel to an unused one by going into your routers set up page.
Xirrus: The Leader in High Performance Wi-Fi - Advanced IT Wi-Fi Networking Tools

It can also help to designate your connection security and encryption. Set your router to use WPA2 and AES "not mixed" also do the same when you set up your wireless connection.

Thanks orbital Shark for the warm welcome and fast reply, i already did as you said. Now only time will tell if restarting my router fixed the problem. I will report back if the problem persists.

Chev65 thanks for the advice while i do not know a lot about wireless channels and how to change them, i am downloading the software you recommended right now to use it.

Checking my connection i can see my security is wpa personal and my encruption is TKIP.

I really have absolutely no knowledge on the subject, i dont know if my security type and encryption are good or causing the problem, so i am based at your advices.

Once you run the software it should be really easy to find an unused channel, you will be able to see which channel you are using and your neighbors connections also.

After you find a clear unused channel go into your routers page by typing the default gateway into your browser. Look around for a place where you can change the channel to one that isn't being used as per the Xirrus software.

I'm not familior with your particular router so can't say exactly where that setting might be.

Keep in mind that the latest firmware for your router was back in 07 which was before Windows 7 came out, therefore your router may not be compatible with Windows 7 and a new router may be required unless you can find a more recent firmware.

I think i finally found the channel you mentioned. Xirrus says i am using channel 11, and i can see that one of my neighbours is using channel 11 too. Could this be the cause of the problem?

And if yes what channel number should i enter at my routers interface to change it?

Wow you are right and the irony is i bought this router just a week ago. i guess i should have made a more careful selection before i bought it.

You can use any channel that isn't being used, doesn't seem to matter much. Yes channel cross over can cause frequent disconnects, this is espeically true with Windows 7. I certainly hope this is the problem because it's an easy one to fix.

As for the firmware problem, it can go either way, it might work or might not. I would think if they are still selling your particular router that it would work with Windows 7. I can tell you that many types routers require a firmware update in order to work correctly with Windows 7 but I'm really not familior with your router so can't say for sure.

I already changed it and set it to channel 2, which from what i can see in xirrus nobody from my neighbors is using. I really hope that this was the problem because buying a new router would set me in expenses i cant really afford at the time.

Anyhow if the problem happens again i will let you know.
Thank you very much for all your help and advices, i really appreciate it
