Dell XPS 13 2015 Intel Wifi Bug

Hi all, I was wondering if someone who has a Dell XPS 13 (2015/Broadwell) with an Intel wireless card (as opposed to the Dell Wireless/Broadcom card which ships with most configurations) could try and reproduce the following bug for me:

1. Disconnect from power supply
2. Connect to a 5G network (in particular I encountered this bug with a Virgin Media Netgear router)
3. Load google.com. This may work, but any subsequent requests will time out.

It looks like there's some sort of power saving regime which is breaking compatibility with 5G networks.

Many thanks.

EDIT: Forgot to mention that I tried booting into Ubuntu and I could not reproduce the issue there. So this is definitely a software problem.

 

I don't have this issue but I have a very loud high pitch sound coming from this wireless card. Going to return it for the broadcom one

 

Just fixed the high pitched noise on the wifi card, it was due to old drivers.
Search for Intel 7265 AC drivers, install the intel driver update utility, follow on from there.

Let us know if that solves anything.

 

Hey, just tried your steps (although I had already tried getting Windows to automatically find and download the latest drivers through the device manager, but apparently this utility isn't that clever) and it found new drivers. I installed them and restarted but the problem persists. It is odd that I'm alone in having this very specific issue. Already had the engineer round today (replacing a wobbly key on the keyboard) but don't think this is a hardware problem since, as I mentioned, it works on Ubuntu. And it's more a minor annoyance than a serious issue anyway. Would be curious to see if anyone can reproduce this, though...
