Problems with WIFI on Dell xps 15 L521X

I got my new xps 15 yesterday, it works great, looks great, I am generally satisfied. (even if it's hot all the time)

It is, the WIFI doesn't work well at all, I'm 2 meters of my box right now and I feel no problems, but as soon as I get on the floor in my room, my signal rate is significantly reduced, I have yet to upload a video on youtube, I was downloading a Steam game yesterday and dl speed has fallen to 6 mb/s! It's awful, if this problem cannot be corrected, I'll be back from mine and will not buy any other product Dell, I don't see how a laptop computer cheap that can have this kind of problems. (because I heard that I was not alone, many people have the same problem)

Anyway, if anyone of you has a solution to my problem (like a Bios), I would be really grateful.

Thank you!

(Sorry for my English, I'm french)

I got it to work!

First of all, speed will always get down when you escape the modem - we must admit, it does more information about these systems - compared to other laptops or other electronic devices.  So given that clear, I had updated the driver wifi for the last from 2014 and I lived the question mentioned that reading things that people have tried, I decided to DOWNGRADE (ROLLBACK) the Wifi driver to an earlier version.

I did this go card options, driver as shown in the picture.  HOPE IT WORKS FOR EVERYONE because it's a good machine and so sad that the issue of the design has affected all of us.

  • Problems with wifi, bluetooth and gps in my iphone after updating iOS 6

    After that the last iOS 9.3 update my iphone 6 has problems with wifi, bluetooth and gps. Now, my wifi connection is slower and falls easily on a short distance. My bluetooth does the same. But the biggest problem is the GPS on my phone. I tried Island:

    -By doing a reset network

    -Do a reset total and restore my phone

    -To restart my phone twice.

    -Audit and third-party applications unnistalling

    Nothing works. I was in the apple store where they checked my phone and they say everything is ok with the phone. I'm not crazy, and I know when something does not work correctly. Also, I think it's iOS 9.3 update a reaponsible for my phone issues.

    Please fix bugs fast.

    Having the same exact problems since the upgrade. In addition, battery drains very quickly now, and sometimes the phone becomes very hot. It took to the Genius Bar and they told me everything was normal in the diagnostic tests. Restored, restarting, etc., and always the same problems. GPS locates me, but then don't follow my movement at all and told to go outside as the gps is not detected even if I am outside. Bluetooth connection to the car and watch grave intermittently. Signal WiFi is greatly reduced and falls easily.

  • Problems with WiFi from Toshiba and their lack of support - you're not alone

    For those of you out there problems with WiFi on a Toshiba laptop, you're certainly not alone.

    Over the past years, I have noticed a growing number of different brands and models of computers laptop toshiba and laptops with the same problem.
    Last year, 100% of the toshibas that came in my workshop have had this problem, it is about 75% of the laptops that I fixed.

    These models have all hardware wifi (Agere, Intel and Realtek)

    The wifi switch is on, on the same computer, some programs to detect as being market, others see it as extinct.
    What, it doesn't connect to a same wireless router when used to.

    Responses of toshiba were the usual non-professional form response from: it must be the router, try to flip the switch, you have updated the bios?, update the drivers et al.

    It is a software problem, and given the number of people on this forum talking about the same issue, it's a great.

    Often, I came across the issue of windows for communication services wireless disabled by software of Toshiba and I believe, that it is a conflict between tosh software and various other (zone alarm, windows and al.)

    In some cases, the software seems to intervene and to corrupt the OS from windows drivers and interfere with their implementation and enforcement, which is worrying, the software doesn't have to touch all areas. (if not, what is the point of a BONE in layers)

    I sometimes managed to force to work (for example manually restart the services), but these solutions are not a "clean way" of doing things.

    The most reliable way to solve this problem seems to be, backup your data and reformat back to the manufacturer's specifications, and then immediately uninstall the software from toshiba and update the drivers terribly old (even those on the site are about one year more up-to-date for the model I'm working currently on.) Unfortunately most of my clients is companies that need a LOT of data stored in different saved locations, then a ton of programs specialized to be reinstalled, which is slow and costly.

    Message from TOSHIBA:
    Please make it a sticky in this forum for all the REAL solutions, not one of the threads that I watched with your suggestions has been resolved.

    If there is little no support for your products in this regard, I will contact the ACCC, choices, and associations of trade fair with an open letter that I ask all customers affected to sign, and I will put a national call for people with the same problem to come forward.

    I would like to ask also if you encounter a problem where your wifi stopped working and it does not detect or work, please just post "bump" under here so that we can keep way reasonably clutter free.

    I used to recommend Toshiba and Asus for laptops, now, this list is one.

    You can do what you want but as mentioned above; WiFi problems are not specific to a laptop manufactures, you'll notice WLan issues on computers (laptops, desktops computers) all manufactured products.
    I had 4 different books of four various manufacturers and ALL had problems of WiFi, but most problems could be solved by the driver update, change, or reset of the router are.

  • Problems with WiFi after put 10.11.2 up-to-date.

    Mid 2011 iMac.  Problems with WiFi after put 10.11.2 up-to-date.  No associated network.  Everything was fine before the update. All the pre 10.11.2 device works fine.  Anyone else having issues?  I have to disconnect and reconnect manually.  WiFi drops every 5 to 10 minutes.  Nothing has changed on the machine something of the update.

    Please do not comment on the age of the system.  Achieve a Mid 2011 arrived at a possible replacement point.  I have many other new Mac at home.  The Mid 2011 is spec'd with 16 GB of RAM, i7 and SSD.  It's always very fast.

    Thank you in advance for the answer...

    Hi Captainsniz

    There are a few things to try. Keep doing this until the problem disappears.

    First of all, if you have not already, shut down the computer completely, wait about 1 minute, then restart.

    Disconnect the wifi network either via system preferences, either by pressing the "Option" key and clicking on the wifi menu bar icon.

    Reset the DHCP lease by going to system preferences > network and show Advanced Options, and then click the button to "Renew the DHCP lease" TCP/IP tab.

    You can delete the wifi network of system preferences > network > network name... then close system preferences. Then reopen and add the network in.

    You can also restart your wifi router, it erases the old connections. Most of the routers you just turn off and wait a few minutes, then restart. You can also reset your ISP modem if you have a.

    Finally, you can try to reset the PRAM and SMC on your Mac. I'll get this info here on Apple Support KBs for your particular Mac.

    Be sure to back up your computer.

    Hope this helps, Greg

    I bought ver2.0 WRT350N and I have problem with WiFi. WiFI is not working no signal and WiFi even not blink. I did the Firmware Upgrade to the latest version, reset several times 30-30-30, but it does not help. I'll be appreciate for any response.

    Concerning

    Robert

    Thanks a lot for your answer. I have reset the router for 2 minutes, but it's not helping. It looks like this: after the power cord to the electric light taken router is green and blinks twice 10 seconds more late light output changes from green to yellow color twice safe. I can ping the router, I can connect to it via the web page, I can update firmware via the web page. I see all the options. I can turn on and turn off wifi but the router does not give any signal radio (wifi)... and of course wireless light is black. I tried to download the firmware via TFTP without success. I don't know what more I can do...

  • Problems with wifi, I have a wifi extension in my house and I can not connect

    Original title: Wifiproblems

    Problems with wifi, I have a wifi extension in my house and I can't connect it, I try with support but it did not work. It's a shame in a new tablet to have this problem

    It only happens with the tablet surface, not with other devices

    It's an easy way to solve

    I saw a similar situation in forum wireless, they have solved the 'limited' problem by disabling the Extender, and then turning turn it back on. He solved their problem, and it is easy to try. I hope it works for you.

  • Problems to reformat my Dell XPS 710 desktop computer.

    I have a Dell XPS 710 desktop computer and I'm trying to reformat my computer. I tried pressing F8 at startup and do a repair, and I get an error Unmountable_boot. If I start the computer and press F12, the hard drive does not work with my drive. Is there another way possible I can reformat my computer? I'm running Vista on this machine.

    Hello

    1 - is the computer come pre-installed with the Windows Vista operating system?

    2. do you have a re-setup for the Windows Vista operating system disk?

    3. do you have external hard drives connected to the computer?

    Method 1:

    The error indicates that the hard drive has failed. I suggest you to remove or top-sheet all external hard drives except the one in which the operating system is installed and check if the problem persists.

    Method 2:

    If you have the Windows installation disc, I suggest to fix the computer using the disk and check if it works.

    Reference:

    What are the system recovery options in Windows Vista?

    http://Windows.Microsoft.com/en-us/Windows-Vista/what-are-the-system-recovery-options-in-Windows-Vista

    Method 3:

    If the computer came pre-installed with the Windows operating system, see the link to contact Dell support.

    I also suggest you check with Dell if they have any hard drive diagnostic tool that could help the issue.

  • Problems with WiFi. Problems with the Wifi adapter driver.

    Hello

    I have a Dell Inspiron 3520 with original 8 Windows installed on it. Wireless settings worked fine until yesterday but anyway its no longer works. I don't see any WiFi option and no wireless networks are also getting detected. Although his active on the network and sharing Center.

    The details of the pilot are:

    Dell 1703 802.11b/g/n (2,4 GHz) Wireless

    The internet LAN connections are working properly. When I received a diagnosis of the wireless connection, he said that there could be a problem with the driver for the WiFi card. I also tried the system restore, but the problem persists.

    How can I sort this problem?

    Most often when a device does not work, it is because the driver is damaged. Re-install a new copy should help
