Very slow internet browsing on brand new XPS 13 9360 over Wifi.

Have messaged you my details in the hope you can help !

my new 9360 also has terrible wifi. It seems to have a strong connection, but just drops packets a great deal. I am currently tethering through my phone which works super well on this wifi connection.

Please don't just send help by private message we all need to see the results. 

I understand that these wifi issues were present in last years model, it is very disappointing that they have not been addressed in this premium laptop!

Thanks for sending the information, guys! Let me look into this further and see if I can find anything. 

If you notice anything else please update me.

Best regards,

Brad

Thanks again to everyone for sending me info on their systems. I am going to be out of the office until Monday, but wanted to post this before I was out. 

On this thread (from the users that have sent me their system info) it looks like everyone has the Killer Wireless 1535 card (if you do not, please PM me your info). This is a bit outside of what I have seen recommended so far and if you have already tried these steps please let me know. Also, before trying this please make sure to have the original Dell issued drivers handy in case you need to reinstall them, here is the direct link (for the older drivers) but you can also enter your Service Tag on the Dell support site to download them there as well. Please note that the fix we will be trying will not be using this driver, but this is just in case you need to revert back.

Here are the steps to try:

1. Download the latest Killer Driver Suite direct from the manufacturer's site at this link.** 
2. Uninstall the Killer LAN / Wireless software from Programs and Features.
3. Uninstall the LAN / Killer 1535 driver from the Device Manager (it should be listed under network adapters).
4. Restart the system.
5. Install the downloaded driver (remember to try the one downloaded from step 1 first!)
6. Go to Device Manager
7. Look for the Killer Wireless Card 
8. Right Click and go to Properties
9. Click on the Advanced tab
10. Select Wireless Mode and change it to 08-11a/b/g/n

Click Ok, and then test the wireless connection after it reconnects wirelessly (you can try doing a system restart but it should connect just fine). I would recommend testing the card how you were previously to see if anything has changed (faster/more reliable connection etc.).

If after these steps the wireless is still underperforming, then go ahead and repeat step 2, 3 and 4, but this time instead of reinstalling the new driver and suite software try to let windows find the driver on its own (after the system restart). You might need to go to Device Manager and try to force the system to search for the driver. I would like to see if by not having the suite software installed if it changes any of the wifi performance.

Please let me know how this goes, and good luck. I am hoping this corrects some of the issues! 

Best regards,

Brad

**If this newer driver suite does not work, then use this one (before going back to the Dell Driver). If for some reason these newer drivers do not want to install, go ahead and try steps 2-4 with just the Dell Driver and not Software Suite. I am thinking there might be a conflict being created with the software suite, but this is just a thought and something I would recommend testing.

tried all that.  Wiped the laptop and reinstalled windows 10 from scratch with MS drivers only.  installed killer software.  Nothing is helping at all.

Please tell me details about what registry changes and network adapter changes you had made to help with this issue.  Not clear what you had done.

Thanks for the updates, I am sorry to hear that it didn't help. I am going to see if I can find anything else that we can try. One other thing to add is that after trying my steps make sure to uncheck the option "Allow the computer to turn off this device to save power", this can be found under the Power Management tab in Device Manager under "Properties" for the WiFi card. I figured it was worth a shot, especially if the software suite was removed.

Let me know if anything else has changed.

I am also curious on these regedits, I have not heard of this but would be interested in hearing about them.

Best regards,

Brad 

Hi everyone -- I have had a new Dell XPS13 on order since Nov 20, and it is on hold indefinitely due to a wifi connectivity issue.  Wonder if it's the same one that is causing everyone here problems.....

I got my new 9360 yesterday (wifi adapter: killer wireless 1535) The wifi disconnected every time after 15 to 20 minutes while all of my other devices (laptop, cellphone, and tablet) work fine. It shows "connected, no internet" with a triangle malfunction symbol on the wifi bar. I've updated the driver but doesn't seem to work. Is anyone's issue solved?

Hi Jalapeno_lt,
Disabling Intel Speedstep seems to make a big difference indeed.

Can you explain in more detail what you changed on the power options?

Add me to the list of XPS 13 9360 WiFi issues.  I'm seeing the same issues as everyone else is describing, and not having issues with other devices on the same network.  I'm getting ready to initiate a return unless this gets resolved, which is a shame because otherwise I really like this laptop.

Hi changsy,

Thank you for reaching us here. I request you to follow the instructions from the link shared here dell.to/1M6fhdj and let us know the outcome.

Also, I request you to share the system service tag, registered owner's name and email via private message for our reference. You could send us a private message by hovering the mouse pointer over my user name and adding me as a friend.

This definitely seems to be an issue with the Killer 1535, either hardware or drivers.  I imagine that replacing it with another card like an Intel version would help.

Well after getting nowhere on this issue and being told it's not a common fault, I gave up and returned the laptop.  Like you I am disappointed as the laptop itself was good !  Now to find something else !!  HP X360?
