WIFI problems on Dell xps 15 L521X

Jump to solution

I got my Brand new xps 15 yesterday, It works fine, looks great, I'm overall satisfied with it. (even though it gets warm all the time)

 

Problem is, the WIFI doesn't work well at all, I'm 2 meters from my box right now, And I'm not experiencing any problems, but as soon as I get upstairs in my bedroom, my signal speed drops significantly, I can't even load a youtube video, I was downloading a game from steam yesterday, and the dl speed dropped to 6mb/s!! That's awful, If this problem can't be fixed, I'll be returning mine, and won't buy any other Dell product, I don't see how a laptop that pricey can have that kind of problems. ( because I heard I wasn't the only one, a lot of people have the same problem)

 

Anyways, if any of you have a solution to fix my problem (Like a Bios), I'd be really grateful.

 

Thanks !

I got it working!

First and foremost, speed will always get down when you get away from the modem - we have to admit, that it does it more on these systems - compared to other laptops or other electronic devices.  So having that clear, I had updated the wifi driver to the latest one from 2014 and I was experiencing the mentioned issue, reading the things people have tried I decided to DOWNGRADE (ROLLBACK) the Wifi driver to an earlier version.


I did this going to the adapter options, driver as the image shows.  HOPE IT WORKS FOR EVERYONE because this is a good machine and so sad that the design issue has affected all of us.

Problem is, the Software you gave me isn't valid, it says it can't be 'retrograded',

Plus, I'm experiencing difficulties, following your instructions, Cause I don't succeed in Chaging my windows 7 langage, I find the section to do so, but it always shows french ... Could you help me ?

fritefighter,

 

Did you recently install/reinstall the operating system?

 

Try these FRENCH Intel Centrino Advanced-N 6235 Bluetooth DRIVERS.

No I haven't, should I ?

I have not done anyting with my laptop yet, Only things I've done: change wallpaper,  Download 2 games on STEAM, and download google chrome, I highly doubt this could have affect my wifi reception

fritefighter,

 

What virus program came with the computer?

 

What virus program and firewall are you currently using?

 

Places to look to see if your Connection is enabled Cold be as simple as pressing Fn and F2 or F2, even the switch on the side on some models.

In fact i also have this issue with my WIFI and so do many other L521x owners, i have resorted to returning my system until the problem is confirmed fixed. There is also a CPU throttling issue on some models. It is most likely a bios fix and will be solved soon, but to just be safe i didn't want to count my chickens before they hatched. Other then that i love the system i just cant over look it.

I'm Using Macafee

I mean it's a shame having this kind of issues on such a system, I was looking for something effective and good looking and I didn't want to buy apple at all, And you guys came with an stunning alternative to the macbook pro, It's a shame it has such ridiculous problem. 😞

To Dell employees, I'm leaving for vacation tomorrow and won't have my laptop for a week, I won't be able to send it back, or find out if there's a solution.

-do you know if such a technical problem is included is the standard warranty ?

-Do you know when the bios would be released ?

Thanks.

Other problem, I'm having is that it seems you can't use the SSD as a normal disk

When I spoke to tech support the xps warranty covers basically everything from accidental damage to other issues with the system, they said that they would exchange my computer, and said that the new system should work. As this issue is common for the system I knew that the exchange system will most likely have it also. they assured me that Dell computers go through testing before they are shipped, I then went on to say that I believe it, but if the issue was detectable by their standards it would not have arisen in the first place. That is why I am returning it.
