XPS 14 wifi issues

Question

Hi,

I got my xps 14 today but the wifi connectivit is really aweful.

It is giving upto 50 mbps when I'm sitting within 2-3 m of the router but getting reduced to less than 1mbps if I go bove 8-9m of router.

I've Killer Wireless-N 1202 (2.4GHz and 5GHz) on my lappi. I also tried updating the driver to the latest version but no help!

I heard a lot about wireless N version that they work fine with these xps laptops but not in my case.

Even I can't see the 801.11n option in driver advanced properties. Attaching the screenshot for reference.

Any help would be much appreciated!

Hope this problem gets resolved otherwise I'll have to request dell to give take this product back and give a refund.

Thanks

Prashant

Hi Prashant,

I recommend you to update the driver from the manufacturer’s website. Click on the link below to update the driver:

Select the appropriate Operating system before downloading the driver.

Let me know the status after updating the driver.

Hi Sujatha,

Thanks but this has not helped much. I have updated the driver from manufacturer's website, still the speed is around 1-2 mbps while my old DELL LATITUDE give upto 20 mps at the same place.

I have also updated the BIOS as an update was available for the same but no help!

Is there any advance that I need to do? Could you please help?

Thanks

Prashant

Hello,

I realize this is a bit late, however I found the fix for my Dell XPS 14. I found that even after updating drivers, etc, my WiFi still was slow. What I didn't realize is that there are settings in the Power Options that cause the WiFi chip to use less power. If you go into your Advanced Power Options, then click on Wireless Card (or something to that extent), then set it to "Maximum Performance" it should fix your problem. It worked for me, let me know if it works for you.

I've just resolved this problem, and for reference here is what I found out. This is an extremely widespread problem with this model of laptop, and various things have been reported to help. However none of them are a definite fix. Here are some of the suggestions:

Updating drivers (didn't work for me)
Updating laptop BIOS (didn't work for me)
Turning off bluetooth (no noticeable difference, and I use bluetooth regularly)
Turning off power-saving features for the wireless card (didn't work for me)
Adjust wifi settings to change wifi channel or force wireless G, wireless N etc (didn't work for me)
Replacing the wireless card with an identical part (I didn't try this)
Replacing the wireless card with a different model (this did work for me, see below)
Getting Dell support to replace the whole screen assembly, which includes the wireless antennas. Apparently the more recent replacement screen assemblies are a new design which improves wifi reception (I didn't try this)

What worked for me:
I changed to a completely different wireless card. I removed the Intel 6235, and replaced it with an Atheros AR5B22 / DW1901 (which I bought for just a few quid on eBay). In most situations around my flat, my actual wireless throughput has increased from an unreliable ~10Mbps to a reliable ~50Mbps.

Hope this helps.
