Wireless card seems slow on my XPS 14z

So far, this is what i have done and my wireless seems to be working a lot better.

I followed the steps from above:

1. Download the Dell driver for the wireless

2. Download the Dell driver for bluetooh

3. Download the OEM Intel 6230 driver (Consists of one program for the wireless/bluetooth)

4. Use the driver programs from steps 1 and 2 to uninstall the stock drivers then install the driver from step 3.

5. Disable and turn off all bluetooth settings

6. Change the power management settings for all profiles to have "Maximum performance" for all 'Power Saver' options.

Only issue i now have is that i get a "Adapter not found" for the My WiFi

I am truly disappointed in Dell not doing anything about this problem. I just ordered a Intel 6200 at my own expense. I will let you know how that works out.

The 'blind' Dell troubleshooting continues. They seem to approach it like this wasn't a known issue by now.

Today I had my "wifi inverter board" replaced. That seems to have made the problem worst.

Now Dell is offering to replace the whole system a second time. I only wish they confirmed that 'something' is different in the new system (i.e. "we had problem with a batch of 6230s but these ones are new and working")

will let you know when the third system comes in

Yes, same here. How long until Dell is going to fix this?

As mentioned above, I installed an Intel® Centrino® Advanced-N 6205 (so different than 6200) but still get the same slow speeds. The problem must be in the antennas and shielding. I am going to return my system.

I have same problem with my new XPS 14z. It's looks even if you get replaced laptop from dell didn't fix that problem. So it's may all laptop with Intel® Centrino® Advanced-N 6230 have that problem.

Can I change Intel® Centrino® Advanced-N 6230 wireless card to other card for example to Atheros?

Dell can you send a manual how to change wireless card to XPS 14z

@Terry: How about 39 pages!!! with people having the same issue with their 15z laptops?

You Dell guys should start taking this seriously. No more smalltalk please. In my case the OEM Intel driver did improve performance at close range to the access point. But the range is far, and I mean FAR below an acceptable level. I've tried different setting under the advance tab in the device manager to improve things, but without result.

I had a technician from Dell come by my House and he did switch the wireless card wit no success.

I need that Laptop to travel and he told me that if we ll complain to Dell, they would write a new driver. I just do not have that much time to wait. He also told me he would inform Dell, but they have not replied yet?

Any ideas out there, what is here to do or do we have to send those faulty laptops back?

I already spend so much time on it trying to figure it out and have put my Software and Documents on it?

What a shame that none of Dell people saw this coming?

Search for and Open "Device Manager"

Under "Network adapters", select your Intel adapter > right click, Properties > Advanced > Ad Hoc Channel 802.11 b/g (at least that's what mine has!)

I made a call to Dell to request full refund for my XPS 14z nobody sorted any problems with that laptops model. Next week someone coming to collect from me that laptop. I like that laptop style, but I can't stay with this problems, specialy when hyou spend €900

That is too bad. Will have to do the same. I cannot believe that they have not figured out the problem, in 6 weeks,

what is worse is that the same issue with the 15z has been reported for over five months, yet Dell is even to aknowledge the problem. Every contact I had with Dell support, they deal with it like if it was an isolated incident. I am waiting for my second replacement but I am not hopeful. A true shame, because the laptop itself is pretty good.

When I replace the Intel N 6230 for an Atheros AR9285 the wireless connection (range and speed) is OK.

So it's not an antenna issue. It must be either:

- Defective N 6230.

- Dell specific issue with N 6230 (firmware/bios/driver).

- A wireless/router specific issue with N 6230.

Is there anyone in this thread that has experienced this issue with a brand new wireless router?
