HI Anthony,320,

I can understand how this must be frustrating but there are a few things we can try.  First, take a look at this support article and follow it's directions to see if it helps resolve the problems you're experiencing.

Resolving Connection Issues on Your Wi-Fi Network for Windows 10

You may also want to take a look at this support article as well:

Wireless Networking for the Home for Windows 10

You don't mention which wireless card you have in your system but you can go to our support site, key in your service tag, and click on the Drivers & Downloads link to find all the drivers for your model.  

Are you getting any messages before your wireless connection drops?  Does the signal strength seem to fluctuate?  If you try to repair your connection does it connect back up immediately?

For your router, what make and model are you using?   And have you updated the firmware on the router now that you have this Windows 10 system?   Windows 10 uses a slightly different chipset than previous wireless connections do so your router may simply need to be updated to be compatible with Windows 10.

To more efficiently help me troubleshoot this issue please let me know what wireless card you have in the system and the driver version you're currently using.  Please click on my Dell Todd username and send me a private message with the Dell Service Tag of your XPS 13.  Please keep all troubleshooting steps and discussions here in this public thread so that others can see what is done to resolve this issue.

Thank you,

Todd

I'm having a very similar problem. Have you had any luck yet? Also considering returning my machine.
