Hell0,  Dell Inspiron 3543 user here. yes me too, had problem with wireless network after updated Network_Driver_X4Y5C_WN32_7.35.295.0_A01 on windows 10, it seem to be no connection or connection limit ( yellow triangle on wifi icon) , troubleshoot problems option cant help..,  solution , go to device manager - network adapter -  Broadcom 802.11n network adapter -  Driver tabs - Roll Back Driver.

Actually tried something different I combined the windows 10 and 8 driver meaning i installed both packages and that seems to be working for me at the moment, it isnt very stable but it gives me more stability than the braodcom or single packaged drivers.

You can also go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

1. Power Option

2. Click on " Change plan settings " - Balance or Power saver)

3. "Change Advance Power Settings "

4. Tap "wireless adapter settings"

a) " Power Saving Mode "

b) Set Maximum Performance

by default these are on max performance, its not just my laptop having this problem with this particular card my friend has the same laptop with windows 8 and he has been experiencing the same problems with it.

OMG... I have been battling for so long to get the right driver and this finally worked.  Thanks!

@Durban Dominique could you please tell me which one is the right driver? It would be a great help.

I'm actually using a Dell Inspiron 15 3543. When I try to disable the wifi adapter (Broadcom 802.11n) trough the device manager or when connection is lost and I try to reconnect it, the screen freezes, and the only option is to shut off the computer forcing it (by pressing the power button for 3 seconds or taking the battery away) 

I'm so close to change this laptop because I look in tons of pages for a solution (I'm can't send Dell my computer again because I bought it in the US and I'm outside the country for a long time and I'am not thinking in open the computer and change the wifi antenna because is brand new.

I  really trust you can help me. 

Thanks a lot.

Hello Rahd! Thanks for the quick reply.

Is there a specific antenna you recommend? If that's the solution I wil try to change the default one..

I just don't know if the warranty still covers any problem that the laptop may show after opening it or changing parts..

I forgot about this topic tbh but guys there is no cure for this....all the drivers you use even the default ones and generic drivers wont work.....I just changed the wifi card at my local dealer...its an easy change half height wifi card located in the same area where the hard drive and ram stick is....you can practically do it yourself.....as for curing the problem it seems to be the card's themselves that is the problem as NO drivers work for it.

Hi Aaron,

I have that exact same laptop and the Broadcom 802.11n Network Adapter worked for me.  I have had no problems since with my wifi and didn't need to do any hardware changes.

Good luck.  I hope that helps.

Regards,

Dominique
