Wireless Connection - No IP Address

I am having trouble trying to connect my notebook to the internet using wireless connection, when i actually plug in the cable i can connect fine, however when i try to connect using the wireless it seems to be unable to connect. It appears to have a connection (status says connection excellent of very good), however it doesn't retrieve an IP address and i can't actaully connect to the internet.

We currently have two notebook's they are exactly the same, i have compared the network configuration it they appear to be the same, (however i am not very good with network issues). I am stumped as to what to look at next, any help would be greatly appreciated.

Do you have encryption WEP enabled in your router. If yes , temporarily disable it and check if you can connect that way.

Have you gone to command prompt and gave ipconfig /release followed by ipconfig /renew to see if you can get an IP address that way..

It would also work if you just restart your laptop and see if it can pull an IP address.

When you connect to wireless network and when you see the wireless connection is "good", what IP address does it display ?

In your wireless connection icon , going to network connections under control panel , try to give a static IP address and see if that would work.

If you are using external wireless cards in both laptops , swap the network cards and see if that way it would work.

Temporarily disable firewall in the laptop and check

make sure the channels and SSIDs are correct

And.. try stopping and starting the Wifi Service..

Go to Control Panel.
Choose Administrative Tools.
Select Services. A two-pane window comes up.
In the right-hand pane, scroll down and click Wireless Zero Configuration.
Click Stop the Service. A progress bar may come up briefly.
Click Start the Service. Again, a progress bar may come up.
Close the Services window.

Also, post your IPconfig here for us to look at..

Start > Run > cmd (OK)

ipconfig /all > ip.txt

(Open ip.txt with Notepad and copy here)

in addition to the good advice above, what firewall(s) are involved? try disabling them and check

I have had the same issue myself and when the computer connects to the wireless network it wont grab the ip address even though it is set to do so. All you need to do is go Start > Run > Type: CMD then press enter > In the dos window type ipconfig /renew

This should go out to your Wireless router and obtain an IP address

Is there a bridge?
http://www.lpt.com/windowsnetworking/regusers/wxpbrdge.htm
try removing it

gbelken99

I can see that you have an ethernet connection on the computer you are trying to set up with a wireless card. Have you tried unplugging that connection and releasing the IP ipconfig /release ? Also is there indication that you are connected to the wireless network? What kind of Wireless are you using namely what brand router? and what kind of configuration? Sometimes these routers have a turbo mode which causes problems with cards that are not the same brand.

There is no bridge, the router brand is Netcomm NB5580W and the confguariton is WPA_PSK and TKIP. The confiuration is exactly the same as the config on the notebook that works, also the hardware and software is the same. The only difference that i have noticed is in the ipconfig (with the Node Type). With the notebook that works the node tpe is mixed however mine is Uknown and also when looking at the access point information mine says that the encryption is disabled whereas the other notebook has the encryption as enabled

stevenlewis

>>also when looking at the access point information mine says that the encryption is disabled whereas the other notebook has the encryption as enabled
this is where I would look, it's having trouble negotiating the encryption

I thought this may be somthing, but where do i set this encryption, i am stuggleing were to find this setting

Fatal_Exception

As Sun suggested in that first comment, I would disable encryption on the Access Point and see if you can connect. That way we will know whether it is the encryption and can start dealing with it next..

My encryption is already disabled, and i don't know how to enable it - as stated in the above comment i need help on knowing how to change the encryption.

Thanks

Thought we were going somewhere with a resolution, but...

Still having problems, this week have since connected, however have know stopped the other notebook connecting, therefore we have realised it is a setting to not allow multiple users to connect to the wireless network, we have logged a call with the technical support and are waiting a response from them. Thanks for you help.

Fatal_Exception

NP.. that setting would create a problem, eh? hope you get that resolved..

Fatal_Exception

Thanks... again, I hope they get you fixed up!
