Integrated wireless sees network but can't connect

Question

I have an Inspiron 9300 with integrated wireless. It was working fine but recently just stopped connecting to my home network. It sees the wireless signal from my router but cannot connect. I tried to use a wireless pcmcia card but had the same result. All of the rest of the computers on the network work great but now my laptop can't connect. Anyone got any suggestions?

I'm running Windows XP-Pro. I have WEP security. My router seems to be fine. As you can guess, I'm on another computer now because I have no connection with the notebook. There is no problem when the notebook is wired to the network. It's only when I'm trying to connect with either my integrated wireless or if I install a wireless card.

Have you tried temporarily disabling the WEP security to see if that is what is causing the problem?  To eliminate software problems, try booting to Safe Mode with Network support.  Can you connect wirelessly in Safe Mode?   Also, from the problem computer, to troubleshoot the problem further, go to Start > Run and type cmd then click OK. In the command prompt window that opens, type ipconfig /all then hit the enter key. Write down the output from this command or select it and save it to a txt file, then copy this output into a reply to this message.   Steve

Steve....thanks for the reply. I didn't try disabling the WEP, however, there is a network in my area that is unsecured and I couldn't connect to that either. I will try the cmd thing though. Can't hurt to try anything at this point. It's just strange that one minuter it's working great and the next, I don't have and can't get a connection. Ray

Well, all that says is that it is not connecting, so it's not very helpful.  Do you have anything like MAC address filtering enabled on the router?  Have you tried resetting the router to its default settings?  Even though you also can't connect to a known unsecured router, since that router is outside of your control, I'm not going to trust those results, but will concentrate on your router over which you have some control.  Do you have any firewalls running on your computer?  Is it possible that somehow the firewall got misconfigured and now won't let you connect by wireless?  Try temporarily disabling the firewall and see if that fixes things.   Steve

Steve....There's no mac filtering set and I have reset both the router and the DSL modem. Nothing changed. I'm wondering if the integrated wireless on the machine has burned out as well as the pcmcia port. I'm tempted to get a USB adapter to see if that allows a connection.

Hi Ray,   Having the EXACT same problem.  Just wanted to ask you to share your solution if you finally are able to fix it.   Thanks.

volcano11 · Answer

Having both the inegrated network card and the PCMCIA slot burned out is very improbable unless you had something drastic happen (dropped the computer, lightening strike, etc.)   The fact that you can see the wireless networks also seems to indicate that these devices are working.  I still think it is a software problem.  Are the TCP/IP properties on both adapters set to obtain an IP address automatically?   Steve

ray1737 · Answer

I don't know if you found your answer to the same problem but mine was a problem in allowing the Intel network manager manage the connection. I changed to allowing windows to manage the connection and got connected immediately.

I hope that this will solve your problem too.
