Hi,

Which wireless card do you have in that XPS 13?  I believe it currently ships with either Dell Wireless 1560 or the Intel 7265 card.   Assuming you have the XPS 9343, here is the downloads page for the XPS 13 9343.  Please make sure you filter it to show drivers for Windows 10, and you can update the driver for your wireless / bluetooth card.   

The wireless cards not reconnecting is probably a power issue.  If you can tell me which card you have in the system I can try and find some information on how to adjust the settings on the card.

I have the same problem (same XPS 13 9343) and just upgraded to Windows 10. Now wireless is very flaky, basically unusable. I have a Dell Wireless 1560. I have downloaded the latest driver from Dell (filtering for Win10). The driver version is 7.35.295.0. Please advise.

BUMP same problem, 1560 wireless card w/ updated drivers.

I updated the driver for my Dell (Broadcom) 1560 wireless card to the latest version (7.35.295.0).  Same problem - both WiFi and Bluetooth are unreliable with frequent disconnects.

I then purchased the Intel 7565 card ($30 on Amazon) and replaced the Dell 1560.  A bit tricky to install, but the problem immediately disappeared.  Both WiFi and Bluetooth now work as expected.

For others with this problem, the link on Amazon is:http://www.amazon.com/Intel-7265NGW-Wireless-Bluetooth-Interface/dp/B00TKO47XI/ref=sr_1_1?s=pc&ie=UTF8&qid=1441399949&sr=1-1&keywords=Intel+7265NGW+Dual+Band+2x2+Wireless+AC&pebp=1441399952858&perid=088FGME6825MYAG0M4XJ

I have a XPS 13 (9343, Early 2015) with the Broadcom 1560 wireless chip. Under Windows 10 it is really bad. Constantly drops connections and only responds to extremely strong signals. Performance under Windows 8.1 was great. Dell really needs to put some pressure on Broadcom to release Windows 10 drivers that do not suhck.

Same Problems got the new xps13 9343 with broadcom 1560 Chip and win10! Always lose the Connection!! DELL pls help!!! Regards

I upgraded to windows at over a month ago and in the last two days having huge problems with wifi... its unusable and without a ethernet port on this laptop a MASSIVE probelm!

this is not what you expect on a top end product.

Ive read dozens of forums and cant seem to solve the problem.  The wifi in my office is fine and no other laptops or phones have any problem.  I put an LTE modem right next to my dell and that works so I know its the dells problem...

My solution was inelegant. I bought a wifi repeater for my house to boost the signal. It works.

I wish they would just write some better drivers for laptop's wifi chip. 

yes i could do that but why should I.  also I travel a lot and use hotel, wifi hot spots...

I'm having the same problems new Dell Xps 13 with windows 10 I updated wifi drivers and have frequent wifi disconnects especially after sleep. Are there any updates?
