WiFi problem with Inspiron 15 3521

This question has suggested answer(s)

Hi I have just purchased a Dell Inspiron 15 3521 and there seems to be a problem with the WiFi as it will disconnect regularly for no reason. It is not the router as I have other Laptops and they don't disconnect and so I think it may be a problem with the Laptop. Does anyone else suffer from this problem?

Thanks

  • Hi,

    Welcome to the community

    Have you tried updating the Driver for wireless card? You can check this link to get the latest driver

    www.dell.com/.../inspiron-15-3521

    If no go, try to login to safe mode with networking. Restart computer, on Dell logo keep tapping F8. Choose Safe Mode w/ Networking and try to test the wireless connection.

    Please share the system model and operating system installed. Also, share the screenshot of the Device Manager with Network Controllers expanded for me to identify which wireless card is installed on your system. Here are the steps:

    • Press the key combination Windows Logo key + R key to open Run dialog box.
    • Type in devmgmt.msc and click OK.
    • The Device Manager windows will appear.
    • Click on the sign next to Network Controllers and expand it.

    Please reply with the information, I'll be happy to assist further.

    Thanks & Regards

  • where is the afterburner ?

  • I do not get the network adapter options you have listed so cannot make these changes.  I have a Dell Inspiron 15 3521 running Windows 8.1 64 bit

  • Saharsh,

    I am experiencing the same problem. I  internet access breaks every few minutes. I disconnect my wireless network and connect it again, it works but drops again after couple of minutes.


    I have Dell Inspiron 15 .....windows 8.

    I tried the steps you suggested to someone.  You asked to change 802.1h1h+d to Strict 11h ....but I don't see any option to chnage. Also I don't see afterburner anywhere....may be its for another model #.

    Please help ASAP.

    Thanks
