I fixed my Intel Wireless-AC 7260 dropouts on my Dell XPS-15 9530

UPDATE 3: Dell claims the final fix is updating the BIOS: http://en.community.dell.com/support-forums/laptop/f/3518/p/19536047/20724109#20724109

UPDATE 2: Forget anything mentioned below. I „fixed“ my dropouts by replacing my wifi router.

UPDATE: nope, just after the blogpost, went awol again

It happened to me as it happened to many people on the internet with the Intel Wireless-AC 7260 WIFI card. Especially but not limited to the combination with the Dell XPS-15 9530 it happened every once in a while that under Windows 8.1, the connection would die in the background showing „Limited connectivity“ in the task bar.

Some needed to reboot, toggle flight mode or simply wait a couple of minutes for it to resolve. It was frustrating because nothing seemed to help. I tried a jillion different drivers and enabled/disabled almost every setting on the driver and on my router without luck.

I eventually gave up and kept installing „my usual“ ™ tools to my new laptop, which includes cfos speed – a traffic shaper to improve ping times and upload speeds when the download channel is exhausted. When I got back on the WIFI I was waiting for it to fail again to investigate further, but it didn’t for an hour now, which is unusual.

What I cen see though is, that the speed is not as constant as it was without the traffic shaper (that tries to keep a low ping) and drops to half or even 1/10th of the avialble speed, but the connection is not dying! But why? The only thing I can imagine is that there are some RX/TX buffers on the card that overflow ocasionally and the card dies for a second, or communication between that and Windows has errors. With cfos however, the transfers are throttled a bit, but the situation is a hundred times better than before.

SUCCESS!!!! Please comment if you can reproduce that or have other questions (I’ll keep you posted if it changes.)

I am not affiliated with cfos, I know it costs 15 EUR to buy. But you can try it for free for 30 days to check if it also solves your WIFI problem

  1. You can resolve this issues by the following:
    – Remove all intel drivers, and instead use the generic win 8.1 driver for the wifi card.
    – Other people have also reported mixed success with disabling all power mgmt options (both power mgmt in windows and power mgmt on teh wifi card driver).

  2. I have a super tricky issue with my 9530. MY power board went out, after 3 in home service calls the power button was fixed but the ports were not reading, only charging and my touch screen wasn’t working. SO my tech got Dell to send me out a replacement. I swap out the hard drives bc I have so many programs and stuff I just can’t reinstall. BUT now my replacements touch screen and ports are not working and m old one’s touch screen and ports are working fine. So can anyone tell me how the touch screen and ports are linked to my hard drive?!?!?!?! Please help me.
