Inspiron 3521 Wi-Fi Problem in Win7
Hi Everyone!
Since i purchased a new inspiron 3521, I'm having a problem in finding the right driver for WiFi. I'v tried all possible drivers for this system. Went through all related forums and Dell supports stuff but couldn't resolve the issue, and its getting really annoying now.
I have tried Network_Driver_2W6N0_WN_WLAN--9.2.0.50_A02 and currently I have DW1704_W7_A04_Setup-7RVKH_ZPE installed. I get very weak signals even if I sit right next to my router. Previously I had win8 and I was not satisfied with it so I turned to win7, but the problem got even worse.
OS is Win7 Ultimate and its x64-based.
The router is fine as my other devices has no connectivity issue.
Anyone please help me out!
Thank you.

Hi Hasy,
I would suggest you to update the BIOS and then uninstall and reinstall the Wireless card driver on the system. Please enter your service tag # on the link below, select the OS and then download the BIOS from BIOS section and then wireless card driver from Network section onto the Desktop screen.

Please follow the steps mentioned below to uninstall the wireless card.
1. Open the charms bar by moving the mouse to right top corner of the screen and inthe search box, Start typing devmgmt.msc and then press enter.
2. Select the wireless card and Bluetooth device under Network Adapter and right click on it
3. Now select properties.
4. In the properties window, under Driver tab, click on Uninstall button.
5. Check “Delete the driver software for this device.”
6. You want to delete the driver click OK.
After the uninstall finishes restart the system and install the drivers by using the file downloaded on the desktop screen.

Hey the problem has occurred again, it worked fine for a day but now I can even see any wireless driver and network controller in my device manager, I have tried the solution multiple times but it isn't helping.
Kindly, help me out in this!

I would suggest you to update the BIOS and wireless card driver in sequence on the system for issue resolution. Please enter your service tag # on the link below,, click on ‘Get drivers and downloads’, select the OS, then download the BIOS from BIOS section and wireless card driver from Network section onto a different system and transfer it your Dell system install it.

Thanks Ravi!
I tried that but now the problem is of poor signals and disconnection problem.
I reinstalled win7 and installed every driver again but the result is still not satisfying to me.
I have done updating BIOS and Wireless Card Driver but no real help. I am not getting if its some glitch or any minor setting issue.
If you would take my service tag and help me out by suggesting more then I'l be really grateful!
