There doesn't seem to be any option to attach a file to this post so I put the logging output on Dropbox here: https://www.dropbox.com/s/mp7473rwwpb74as/05062014_000.htm . See my original post for the time that it failed. I ran the diagnostics in the Pro/Set application while my connection was limited and all tests succeeded other than the ping test.
Let me help you with this.
Checking the information you have provided, I see that you are using the Airport router so I was wondering; can you try a different router for this connection? We have received feedback from customers reporting dropping connection issues with this device.
You can also contact support at the following links for them check on this:

I have the same problem with my XPS 15 Touch (XPS 15-9530) with the Dual Wireless-N 7260 card running Windows 8.1. I can't even seem to get any connections most of the time, it just showed "Connected" but I can't access or ping to any websites, other times it showed "Limited'.
The wireless access point is a TP-Link TL-WA901ND, no other computers/devices shown this kind of problem connecting to the same access point. Updated to the latest driver 126.96.36.199 but it does not help at all.
I'm really frustrated.
Hi Kevin, unfortunately swapping out my router isn't a realistic option at this point. However, as I mentioned in my original description, I also have problems joining wireless networks at restaurants and coffee shops, as well as tethering. So I would say that this is definitely not specific to Airport, although maybe the driver has additional problems with Airport. I will contact support directly.
One correction I want to make is that I have the Dual Wireless-AC 7260 card, not the Dual Wireless-N 7260 card.
I've a Lenovo T540p with Intel 7260AC. Connection drops or is extremly slow.... (Router: Fritzbox 7570)
I had the same exact issue with my Gigabyte P34G running the N 7260 (and later the AC 7260) adapter. I saw a link to leaked WHQL drivers version 188.8.131.52 on this post: Intel 7260? - Page 44 from notebookreview.com. I've been running these drivers since April 30th with none of the "limited connectivity" issues I had before.
Thanks Tom. I tried the 184.108.40.206 version of the wireless driver from the Lenovo website to see if it made a difference. So far it's showing some promise in helping to avoid the dropped connections I mentioned, but I haven't been able to give it enough testing to know for sure yet.
The one thing that I wanted to mention I still have trouble connecting to WiFi hotspots at some restaurants even with the 220.127.116.11 driver. For example, I was at a restaurant yesterday I was able to successfully connect to their public wireless network (the connection didn't show as limited) but I was unable to do any DNS lookups so I couldn't browse the web at all. I enabled some logging during that time and put the resulting htm page here ( https://dl.dropboxusercontent.com/u/9301353/2013-05-08-13-30.htm ). Oddly enough, the Pro/Set utility's diagnostic tests passed everything, including ping tests. The time when I was connected to that WiFi hotspot was around 1:30pm, although I started the connection a minute or two before. I don't believe that it was a misconfigured router, as I was able to load webpages on my iPhone just fine when connected to that WiFi hotspot.
I also included this note on the ticket I filed with Intel. I will do troubleshooting on that ticket and include any updates here on this thread.
Try checking if you have an option under the Adapter properties > Advanced tab called uAPSD and disable it.
The fix is two-fold, as mentioned in two separate comments:
- Update to the 18.104.22.168 driver, which fixed support for Airport Extreme and iOS tethering by fixing a bug in handling QoS levels.
- Disable uAPSD under Adapter properties > Advanced, which seemed to fix my inability to join certain wireless networks.
I am still working directly with Intel support on troubleshooting #2. I was told that they still want to make uAPSD work correctly. I will update this thread if I am able to get a better resolution that does not require #2.
I`m facing the same problem with this device "Intel(R) Dual Band Wireless-AC 7260", the wifi becomes very unstable, it is disconnecting frequently. This happen after a upgrade my ASUS ZENBOOK UX301 to Windows 8.1.
I already install the latest intel drive to solve, but it is NOT working yet. I used "Wireless_17.0.3_e164.exe". And still not working.
We have information that a new coming driver will be released soon to solve this problems but we don’t have an ETA yet.
In the meantime, try updating the BIOS of the unit, reinstalling the driver and testing the driver provide by the Computer Manufacture since those drivers are special for OEM systems.
The new driver 17.0.5 still has the problem, the WIFI unstable.
Do you any workaround for that? or Is there any roadmap to solve this bug? It seems that 7260 has this problem a lot time ago.
