I have a strange issue occuring and am at a standstill. I use a Dell Latitude laptop with Windows XP Professional and my wireless networking has stopped working in my home office.

A few points:

The "Wireless Connection" shows "connected"
The laptop works fine if I plug it into the wireless router.
I have another laptop in the house that works fine (Windows 2000)
I was in two airports this week. One connected fine for internet access. The other had the same issue where it showed connected but internet access did not work
I am getting an IP address, but I can not ping other addresses on the network.
I called Dell this week and they sent me a new card. The problem continues


any suggestions would be appreciated

So, you're getting a strong signal and connecting to router just fine. Is the IP address you're getting on the same subnet as the router?

Have you checked the device manager for an error?

You said you're using XP, so are you using MS's zero config tool or a proprietary tool that came with the card to manage your wireless card?

What do you have for a wireless card?

What firewall are you using?

Q: Is the IP address you're getting on the same subnet as the router?
A: Yes.

Q: Have you checked the device manager for an error?
A: Yes. There are no errors

Q: You said you're using XP, so are you using MS's zero config tool or a proprietary tool that came with the card to manage your wireless card?
A: Using the MS tool. The newest driver came with a tool. I used that too. No success.

Q: What do you have for a wireless card?
A: Dell TrueMobile 1300 WLAN mini-pci card. It is a built-in card that came with the laptop.

Q: What firewall are you using?
A: I was using Windows firewall, but I turned that off while trying to figure this out.

More info: I took the wireless card out of my other laptop this afternoon and installed it w/software in the Dell Latitude. It works fine. If I can't fix this problem, I'll end up using it but that isn't ideal. It has a proprietary program and doesn't have the capability to search for a wireless network the way the built-in one does. I travel a lot and the ability to search for networks in hotels/airports/office parks comes in very handy.

More points . . .

I rolled back the driver . . . no success
I downloaded the newest driver again . . . no success
Since the card is new and does connect to the network at the airport, I don't think it's the card
Since the computer does connect to the wireless LAN with another card/software, I don't think it is the computer LAN configuration.
Since other computers will connect to the wireless LAN, I don't think it's the router config.


I am stumped.

I am having the same problem, except my computer works oppositely. It will connect (w/ no internet) when connect by ethernet cable, but when connected wirelessly it works fine.

DW,

With the other wireless card out, can you run ipconfig/all and post the info back here?

Can you ping the default gateway and www.google.com? Let me know the exact error you get.

Make sure only one config tool is running. Having two config tools trying to manage the same wireless device will often cause problems.

The info from ipconfig looks good, so something must be interfering. Do you have any filters setup on the router? (Especially, a MAC filter)

WHat are you running for a firewall?

Q: Do you have any filters setup on the router? (Especially, a MAC filter)
A: No, I don't. Plus, this used to work fine. I haven't changed anything on the router in years.

Q: WHat are you running for a firewall?
A: I was using the Windows firewall plus the firewall built into the router. During this troubleshooting, I've turned each off to test. No success.

Ok.

Can you run 'route print' and post the info back here?
Also, run tracert 192.168.1.100.

The IP address 192.168.1.100 does seem a bit odd for the router's IP. Did you change it from its default IP?

Do you have ICS setup anywhere on your network?

It's really weird that you can't ping the gateway.

Here's another thing to try:
- Reserve an IP for your wireless MAC address in your router settings
- Do an ipconfig /release and ipconfig /renew
- See if you get the IP you've reserved

It's very, very unlikely that your router-laptop connection is only one-way (that is, DHCP assigns you an IP, yet you can't ping the DHCP server).

If you have completely ruled out the wireless card as a cause, as a last resort, you can do a factory reset of the router... just in a case a configuration change may be causing this.

Q: Can you run 'route print' and post the info back here?
A: I ran it but it is too long to re-type. Is there a way to cut & paste from CMD screen?

Q: Also, run tracert 192.168.1.100.
A: OK, done. 1 - 7 the request timed out. Number 8 was "General Failure"

Q: The IP address 192.168.1.100 does seem a bit odd for the router's IP. Did you change it from its default IP?
A: Yes, You're right. I changed it over the weekend while I was messing around with this issue. I have changed it back to the default . . . 192.168.1.1

Q: Do you have ICS setup anywhere on your network?
A: Sorry, I don't know what ICS is. Since I don't, it is unlikely that it is running.

I agree. It is almost as if the card can send out requests but can't listen for them

I am not an expert at this, but I think I did what you request. It always gave me back the same IP address, but I don't know if that is the same I reserved (which is just "1"). The one it always reserves is . . . .104.

I have reset the router. No luck. To say the least, I am stumped. Right now, I am typing on the computer via a link from the other wireless card, which works fine.

ICS = Internet Connection Sharing

You can Copy from the command window by right clicking and selecting Mark. Then highlight what you want to copy and right click again. Now you can paste the info wherever you like.

I'm having the same problem and I think I've had it before.
I'v just installed a new larger hard drive in my laptop which has a truemobile wlan card and has been up to now been working fine. After installing the drivers on the new disk the symptoms are that data is being sent but nothing received.
I have however found that when turning of the WEP encryption, everything is fine. I have been thinking about this today and I'm sure that XP is still controlling the card and that any changes that I am making in the Dell utility are not taking effect. Another thing I have noticed is that the icon on the task bar when using the new disk shows 2 stepped screens while on the old disk (the one that works) a single screen is shown. I will be doing further investigation tonight and will come back if I find anything.

Sorry it has been a bit since I have updated this. I had the flu last week and then called Dell on Friday. They are scheduled to be out here tomorrow to replace the motherboard.

However, I just resolved the issue entirely. I have a stereo system with some wireless speakers that I use for the back yard. I was cleaning and realized that the plug to the transmitter was still plugged in. After I unplugged the wireless speakers, the laptop logs in without a problem.

Doesn't quite explain why I couldn't log in at the airport, but I suppose they could have been having network problems that day.

Are you running any type of encryption?

Yes, WEP is used with a key.

Make sure you are using the correct key. I had a situation where the computer had keys numbered 1 2 3 4. The router had keys numbered 0 1 2 3. So key #1 on the computer would be key #0 on the router. Using both keys numrered 1 would result in the situation you are having.
