Dell wireless 1390 WLAN mini-card malfunction

I have a Dell Inspiron 6400 laptop running and with a Dell 1390 WLAN mini-card installed and a Broadcom 44/10x100 integrated controller.

Unfortunately I've never been able to get this laptop to function with my wireless Internet, and I strongly hope someone here will be able to help me. You're my last hope, guys!! 

Anyway, here's what happens: Everything's working out nicely, and the computer connects to the network smoothly. After 5-10 minutes of full and unproblematic Internet connection the computer crashes the wireless network i.e. the Inspiron and all other computeres connected to the network is disconnected and my wireless network no longer shows up on the list of available networks.

The network works perfectly with every other computer I've used with it.

I've installed the newest drivers for both the 1390 and the integrated controller from this site. And my Vista is of course also fully up to date.

On the advice of a friend, I've also tried turning the antennae settings to "aux" - Alas, to no avail.

Can somebody out there help me?

Yours,

Kristen

Re: Dell wireless 1390 WLAN mini-card malfunction

mine is a Dell Inspiron 2501 with the same network cards, 1390 WLAN and Broadcom.

It does the same thing.. crashes my home wireless network after 5-10 min, taking out all the PCs connected to the network. All wireless connections fail. They recover after 2-3min, but it's very annoying. Seven other machines, running Win2000 and XP, work fine on the same network.

I upgraded Vista to XP, but the problem persists. I'm beginning to think the problem is in the 1390 card, since that's the only thing that is different between this PC and the others that work.

There's a list of other things to check for Vista on my weblog, see for detail:

best of luck, hope something helps ;-)

What happens if you try to use a different wireless network?  Also, what brand and model of wireless router are you using, and is it running the latest firmware?

Re: Dell wireless 1390 WLAN mini-card malfunction

trying a different network was today's effort.. it worked fine at the library, but their network is unsecured.

So, I went home and turned off WPA-PSK. Now the wireless works fine, didn't drop for 20min which is a new record for this machine. However I don't want to run without WPA so I'm still thinking about what the next step might be.

The router is a Dlink 514, with the latest firmware (first thing I checked). As noted a variety of other PCs with a variety of network cards, older and newer, all work fine with this router and WPA. It's only this laptop that has issues.

Have you upgraded your Broadcom wireless driver as suggested in a similar thread?

Re: Dell wireless 1390 WLAN mini-card malfunction

It's not a Broadcom wireless driver, it's a Dell 1390.. the latest driver for this is 3/4/2008, according to the list at:

I have worked around the problem by disabling the 1390 Wlan card, and installing a Dlink USB wireless adapter. It's a bit slower, but it:

- stays connected indefinitely

- doesn't destroy my network on a regular basis.

Dell Wireless 1510/1505/1500/1490/1470/1395/1390 all use Broadcom chipset and therefore the Broadcom driver is correct...

Re: Dell wireless 1390 WLAN mini-card malfunction

Somms is correct that the Dell Wireless cards use the Broadcom chipset.

I did a quick check of the Dell Support site, and the latest Dell driver for the 1390 card is version A22 (for WinXP <ADMIN NOTE: Broken link has been removed from this post by Dell> or Vista), released on 20 Nov 2008.

Re: Dell wireless 1390 WLAN mini-card malfunction

I assumed that the link that Dell Support sent me (the tinyurl link in my last post), would have the latest drivers.

It shows the driver for the 1390 as being a Dell driver, not a Broadcom one, and it is dated as I noted, 3/4/2008.

There's no way I could find out that the 1390 is actually a Broadcom chipset, nor did I know enough not to trust Dell Support and to do my own searching of the website.

Oddly: when I do search the "Drivers and Downloads", it requires a product identification. If I use the service tag, it delivers the page as per the tinyurl, with the 3/4/2008 driver. If I use the model, it delivers a 2007 version of the driver as the latest.

To get the driver for 20 Nov 2008 - search the entire website by keyword "1390 wlan driver", narrow it to 'drivers and downloads', then order by date.

Thank you for the information. I'll try the latest driver, now that I know where and how to find it..

Re: Dell wireless 1390 WLAN mini-card malfunction

the new driver (dated December 4 2008, now) did not change the behaviour.
