I can see they just released new drivers for the wifi card today but I can't download them. Same for the new BIOS

They replaced the LCD screen which carries the antennas and the WIFI card. Still the same.

When did you have your screen replaced? Apparently, the screen that I got replaced last week was a different design from the original XPS14z screen.

After endless discussions with technical service, and four reparations, they have finally fixed the problem by changing my WIFI card to an Atheros DW1901.

But anyways, it is unacceptable that this should happen in a brand new high range laptop.

I also have an XPS14z (since the end of november 2012), and have the same problems.

During all these months I thought it was only a problem in my house because of my router, but now I'm sure it is a problem of this computer.(some others are working fine)

I tried last week to desinstal and reinstall all the network drivers, and turn everything to the maximum. But the problem isn't solved.

During the last month, It seems to be woth and worth. The wifi network stops every 2 minutes. It is unusable.

I don't know what to do, and my 1 year waranty will end in a few days.

Does anyone realy solve his problem ?

Call technical support and tell them the problem you have. Tell them also to replace your wifi card with the Atheros DW 1901, which is Atheros equivalent of Intel's 6235.

Like I said on the previous post that was the only thing that solved the problem for me.

I called them, and the told me to install the last drivers (just arrived this morning).

Now it seems to work better. I'll tell you in a week if it is good or not.

Dear  didou30, do you have the link to download the new driver for Wifi 14z that you mentioned above?

just go to the dell support, desinstall et re-install the drivers, it should work

Yesterday I downloaded and installed the latest Intel driver (Nov 15th 2012), it improved the connection significantly. I didn't have any disconnect so far. Will tell you more after 1 week.

Here is the link where you can find the downloads:

downloadcenter.intel.com/Detail_Desc.aspx*&DownloadType=%0A%09%09%09%09%09%09%09Software%20Applications%0A%09%09%09%09%09%09

It's for both the N-6230 and N-6235, window 7 (32 or 64 bit). Choose the file carefully before you download.

Make sure you remove all the previous Proset software using Windows Installer cleanup. Restart in Safemode, completely delete the C:\Programs\Intel\Wireless and Wifi and Bluetooth folders. Then restart normally and install the new software.

I also have a bit of problem with the registry. (Cannot open KEY Unknown/components).  After follow this instruction to modify 'permission' from of the Registry (do it at your own risk..), it went OK. www.okino.com/.../changing_windows_registry_permissions.htm

Hope this helps :)

I am also having a real nightmare on this same model.  WiFi "worked" but with the dropout issues noted here even with the latest drivers from Dell.  I tried the latest Intel drivers (15.#.#) and I then got a Network Adapter Not Found error in the Intel My WiFi Technology app (V15.#.#).  So, I removed the drivers and app, went into safe mode and deleted the associated folders.  Next, after a re-boot to normal, I re-installed the original release Dell drivers and utility just to try to get back on track.  Same result.  I then updated to the latest Dell drivers and utility again with the same results.  The odd thing is that the card shows up in Device Manager and it says it's "working properly".  No wireless.  Win7 just says a possible problem with the driver, but it's the latest approved one from Dell and it used to work!

I have been on this task all day to try to revive this unit to at least some version of Dell driver that will wake this thing up.  I hope to not have to do some sort of re-install.  I just want to even get back to the original state of wireless there but dropping out at this point.

Please help!  Thanks.

I have had the exact same problem! Ive gotten my wifi adapter replaced and my CDDVD optical drive replaced(differernt issue). 

When the guy was here he said that he has noticed that the XPS 14z has had wifi issues, that it is strange that Dell hasn't done much about it. Since the replacement didnt help they are coming in a few days to replace the Antenna, Motherboard (bad performance, false advertisement), and the trackpad(it randomly stops working).

I asked for a different laptop. They said they can't do that. In all honesty I feel scammed. 

Just got mine back from a visit to Dell for a new wireless card. Enormously inconvenient in lost work time and productivity. Plus they wiped my hard drive, so now I have to reinstall everything.  That was AFTER doing all the other recommended fixes.

IT STILL WORKS VERY BADLY! I can use wifi on another laptop where this one gets NO signal. They say it is "fixed".

I don't know what to do now.I have no budget for another, and this one is useless in a lot of places I need to work.

DELL --WHERE ARE YOU ON THIS?
