New XPS 15 (9550) - WIFI issues

I have the same issue as well.

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.

A lot better than what i'm getting, Can't even find any wireless networks let alone even enable my wireless card it says enabling but then stops.

I am running Win7 though

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?

Great

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?
