Is MAC address filtering enabled on the router?  If so, have you added the MAC address of the wireless card to the table of allowed MAC addresses on the router? 

Steve

No, MAC adress filtering is off.  

BTW, I also tried rebooting the router.

All new Dell machines come with either Norton Internet Security or McAfee Security suite.  Have you checked to see if the firewall included in these packages is somehow blocking the connection?  It seems unlikely, since you can connect at a hotspot.  In fact, if it can connect at a hotspot but not to your own network, it points to a problem with your router.  You said you rebooted the router.  Does this mean you just turned it off and then back on or did you try resetting it to its factory settings using the reset button on the router?

Steve

When I tried the hotspot I had not yet started Norton. On the previuos try at home only the

XP wirewall was on. Later yesterday I started Norton since it kept bugging me.  I will try without any firewall, will have to rely on the router firewall to keep me from harm.

Problem with the router seems unlikely since two other machines have no problems.

So far I only unplugged the router. I will try reset.

 Tanks for the suggestions

 

I'm having a nearly identical problem. In my case it's a Latitude C840 with a Truemobile 1150 . . . No problem connecting to a Netgear or Belkin WAP, but with a Linksys b/g WAP (WRT54GL), the network is detected, MAX signal strength is indicated, but it won't connect.
Tried it with no security at all (temporarily, naturally!), MAC filtering (checked & rechecked MAC addresses), and WEP . . . nothing.

Anyone else seen this happen?

I am having the same problem with my E1705 that arrived today. I uninstalled Norton, disabled all firewall, etc. took off all security systems for router -- to no avail. My other laptop connects fine to WLAN no matter what I change on the router settings, so I don't think the router is the problem. This is really frustrating, as the reason I forked out the money for the laptop was to use the wireless capability.

It does connect fine to the same router when using the ethernet cable.

Any ideas?

Same here, switching off the firewall made no difference. Ditto with resetting the router.

I just talked with Verizon DSL tech support. She did not know about any incompatibility between some wireless cards and routers.I am fresh out of ideas.

Hi,

I also encountered wireless connection problem when I got my 9400 which is same as E1705. I struggled for a night, and got it resolved in the second night.

It seems all point to the SSID case sensitive problem -- normally window system don't care about case of a letter. However, the newer system and drivers do treat uppper case and lower case differently as they should in the Unix/the other side of the window world.

Here is the LONG steps that I try and solved the problem. (you may need to have wire, i.e. ethernet calble connected to setup your router. Also you can try the short step of just match the case of the SSID in the router and your laptop directly)

1. set the SSID to all lower case in the router, and have the SSID enter the same in the profile in the wireless driver in your laptop.

2. disable the encryption key both in the router and the wireless driver, i.e. set it to none.

3. now click connect and you should get connected.

4. once you get connected, you can start to change the encryption key back to 64/128 bit both in the router and the wireless driver (so you have security on), once that is done, click connect and you should get connected.

5. you can improve the security by change SSID to have both uppper and lower case and select the no broadcast option in the router, and change the SSID in the wireless driver to match that of the router setting. click connect and you should get connected.

By the way, normally just power up or down the system/router to try to get around a problem is not a right approach. It only implies the product is buggy/not ready.

Hope it helps.

I was able to resolve my problem...however I do not know what the actual root cause was....

I have a USR8054 router, and I updated the firmware on it. ONce I had done that, it seemed to work fine. In the process of troubleshooting the router went down a few times before I updated the firmware. I don't know if updating it was what fixed the symptoms, but it immediately connected after I did that.

Try updating your router firmware to see if that helps. I doubted it would work for me, but it did.

Good luck!

Tried all lower case SSID. No change. I also could not find any software update for my router.

I downloaded the driver for the Dell wireless minicard. Upon installation I got a message " starting wireless" or something to that effect. Right after that I saw some signs of life in the form of an active signal strenght meter. I never got full connection though. After a couple of minutes the card seemed to be tired again and went to sleep, never waking up again.  I talke to Dell Tech support and they will send me a new Intel wireless card. See, how that goes. Will be out till end of next week.
