UNSOLVED
Dell Latitude 3330 1504 half card wireless connection very intermittent
Hi Guys,
Just joined the forum to see if anyone can shed some light in regards to the Dell Latitude 3330 1504 half card wireless connection and if you have seen any problems with them.
It had originally started from one machine which was having a lot of wireless problems and no matter what we did(update drivers, reinstall driver, recovery partition and even fresh window install and fresh drivers) it was not working the way a normal wireless connection should work ( drop outs, time outs and sometimes cannot see wireless point) pings are anywhere between 1-2000 to the gateway.
The fix for this laptop was just to buy another dongle and then all was fine until we needed to order more and since then another one has pretty much had it's wireless card, motherboard and then daughter board changed by Dell warranty and still they cannot get it to work.
And now I sit here with another 3 new machines and the first 2 out of the box have the same wireless issue but now having some more luck by uninstalling the DWLAN utility and updating the drivers in Windows but it is still choppy.
We are still waiting on Dells response to the laptops and trying all I can do in the meantime.
The drivers I'm using are below.....any help please?
Regards and thanks in advance!!

Good luck with the Dell Techs as I was chasing my tail for almost 6 months.
I had to go and email the world before I got some decent responses and it came down to using an evaluation driver which seems to work a little better but not 100%.
Hopefully they can provide you access to the same driver after signing waiver forms.
We do not purchase these laptops anymore.....

There seems to be a design or global issue with wifi card on this model.
Sometimes the wifi network refuses to connect, even after reboot. Disabling & enabling the wifi card sometimes work.
Other devices, like Vostro V13 connectivity is working perfectly on the exact same location.
I tried to tweak the NIC options with no success

Here is the exact WIFI card model:
Broadcom BCM94313HMG2L ( ie: DELL DW1504 )

Does someone knows why there are 2 wires per Wifi antena ? ( only 1 cable per antena is used, the other is left unplugged)

Maybe a solution could be to replace the Broadcom card with the Intel wifi mini PCIex card that is also mentioned in the driver section of DELL support for this model :

I understand this is an old thread, but it still shows up in Google. In case anyone is looking for the answer, here it is. The built in wireless card is subject to interference from the USB3.0 ports on the right side of the laptop. Whenever using high speed devices in those ports, wireless transmission becomes very intermittent. This is a design flaw by Dell. The work around is to throttle down your 3.0 devices by using the USB2.0 port on the left side of the laptop. USB2.0 devices seem to work ok on the USB3.0 ports on the right side, but beware of interference from high speed/high throughput. Another option is to use the wired NIC, or USB wifi. I hope this answer clears up some of your frustrations.

Good that someone still tries to solve it....!
This issue is however not solved by above, since a Lat 3330 without any USB attached still loses WiFi connection every five minutes.
My thoughts is that this is a FirmWare issue in the Dell 1504 WL mini card..
And probably does not every driver update contains the latest firmware update.
So if you don't update with the right old driver update you will have an old and fawlty FW.
I will try to solve it on my daughters old school computer. Will be back if I find a solution.
To bad that Dell have not solved this in five years... I hate when they abandon the customer for new hardware before they work!!

Yep the card not perfect .. but thats not why people have problems!
My Latitude was installed by so called IT specialists, and it lost wifi every 5 minutes needing Wifi retstart (deactivation/activation)!!
I started updating Bios to A06.. but no change...
Issue: Updating driver with Windows Update won't update the fawlty FirmWare.
You need to denstall and remove driver, and Dell System Detect will see the right driver and not download it.
Now download the Network_Driver_16R0G_WN_6.30.223.228_A03.
Disconnect any network cable, or it will do windows update again!!
Run the Network_Driver_16R0G_WN_6.30.223.228_A03 program
And if it installed OK you will have an better FirmWare and driver.
Only lost connection once in 60 minutes... maybe not perfect, but better.
I'll continue to update stuff.. see if it improves, and update this post!
(Sorry for accusing Dell for this, but they could have wondered why people have problems)
