New XPS 15 (9550) - WIFI issues


I have a new XPS 15 -(9550) - Windows 10 Pro

I am getting issues with the wifi connection dropping intermittently.

I have another two other dell laptops and the wifi connection is rock steady.

I've updated the wifi drivers to the latest on the dell site  Communications_Driver_NYN84_WN32_1.519.0.0_A01.EXE

I have also flashed the bios as per the dell site:


Finally I have removed the wifi device drivers completely and reinstalled

However my wifi connection still drops. The only way to re-instate is to switch the wifi off on the laptop then back on again.

Please can you help?

Looks like I found the solution.

Disable all the power saving for the wifi card.


1. go into control panel/hardware and sound/power options/edit setting.

2. click on advanced power settings.

3. Scroll down to Wireless Adapter settings

4. on power saving mode, set On battery to Maximum Performance.  Set Plugged in to Maximum Performance

Since I've set these options 3 days ago, my wifi has been completely stable. Hope it helps you guys too.

Since the latest WiFi driver update (few weeks ago), I don't have any issues with my WiFi anymore!!!

It took them ~5 months to solve the problems, but for me now finally everything is OK and the whole laptop works perfectly.

Same issue here.. In my case probably the antenna is broke. I also see scattered bars, so they have to replace the whole screen, where the antenna's are also located..

Thanks singh_s!

This problem has been driving me crazy since I got my laptop and I didn't notice that it only happened when I was not plugged in.

Only happens when the laptop goes into a S3 Sleep State... If you disable sleep in BIOS it fixes the issue which needs to be addressed by Dell.   Its funny though if you enable hybrid sleep / hibernate before hand, the system won't sleep but even though sleep is disabled it will still go into hibernation... something is up lol.   The good thing is WiFi still works after hibernation.

Here is some event viewer data:

Is Dell the only laptop that doesn't use the Intel wireless chipset?  Really.  I can't find a single major brand laptop that uses something other than the Intel chipset.  At least you can download the Intel drivers from Intel and get timely updates.  No such support from the Dell/Broadcom dynamic duo.  Thanks Dell.

I've noticed whenever the microwave is in use, the wireless driver crashes. I know this because I went through SupportAssist and found that the wireless driver failed and caused the crash. The microwave is between me and the router, but it shouldn't crash. My other laptop which is years older now temporarily loses wifi signal then hops back on when the microwave is done. Anyone else has this problem?

I'm having the same problem.  4 desktops and my old Toshiba laptop work just fine, but if I'm not in the same room as my router with my new Inspiron 5559, I'm getting intermittent disconnects.  My router is wireless-N, so I've ordered a wireless-AC one that should be here tomorrow.  I've already disabled sleep mode, so I hope the new router works better.  This is a time consuming frustrating problem!  -(

You could try channels on the router. There are utilities which help you pick the least used channels. This helps when interference is due to other wireless appliances, but may nof be able to solve the microwave. I have never heard of a microwave issue. Po erhaps you should get an RF meter and check for a radiation leak. With agn routers, disabling the "n" function sometimes helps disconnects. Look in the Advanced tab in the Wireless section of the Device Manager.

It's been working just fine for me since I turned off sleep mode.  I also changed the power options for Wireless Adapter Selttings to Maximum Performance.  I'm still using my TP-Link wireless-N router, and this thing's been flawless for the last 4 hours with streaming audio (Pandora) IE and Firefox all running continuously.  Time will tell but I believe those tweaks have made the difference.

 It's nice to try to "save the planet from climate change" if you can do it without causing all kinds of grief.  But if you try to do this, you need to test and make @#$% SURE it's not causing more problems than it potentially saves!  Mr. Dell needs reminding of this.

I have a similar but different issue.  When my two-week old XPS 15 9550 sleeps while the wireless is connected, when it wakes the wireless driver cannot be found - as if there were no wireless card.  Is there a fix for this?

Same problem here.

Even when I shutdown the laptop, sometimes the device just disappears.

The device manager in win10 shows that the device cannot start:

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.


Not sure if this is power related, as it works for 5-10 minutes and then stops working.
