WiFi problem with Inspiron 15 3521

Hi,

Welcome to the community

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

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.

hi, I am sandesh hegde me also having same problems. Please give a solution for this

Hi Sandesh,

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.

I have the same issue. My wifi randomly disconnects after few mins. Its very annoying. The tech had come out and changed the wifi card and the motherboard but no solution.

Please provide a proper solution to this problem.

That was a big help. Its been a week now and the wifi has not disconnected even once.  I have done all the modification as mentioned above and it seem to have worked. Thank you so much.

Hi aamer21,

Glad to know that the issue is resolved. Feel free to reach out to us if you need any assistance in future.

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

reinstall wifi driver maybe then work
