Intel AC7260 problems

Hi there, I just excitedly bought 3 AC7260 cards for all our laptops in the house cause we upgraded our router to the RT-AC66U and let me tell you I am soooooo NOT impressed with these cards. They are horrible, I cannot keep a consistent connection with my router.

Computer # 1 is a Dell 7720 running windows 8 and all I keep getting is constant unable to access network page errors that only say on a chrome web page:

Error code: ERR_NETWORK_CHANGED

In my intel event viewer I get around 3 lines marked Information..... authenticating wireless profile XXXXX every minute!!!!!! This can't be right???

Computer # 2 is an XPS 15 running windows 7 home and I get the same problems as computer # 1 just not as many chrome ERR pages.

Computer # 3 is an Alienware M18 and it consistantly drops the wireless connection too. I had a bigfoot card in there previously and NEVER had any problems with losing wireless connections.

I'm using all the latest newest drivers on all my laptops and i just can't believe how troublesome these 7260's are. Anyone else actually have a 7260 thats rock solid and if so, how did you do it?

I join this community for one reason and one reason only. To express my utter frustration.

This card is absolutely garbage and in the past - God only knows how many - months there has been 0 progress. Every single fricking update brings out the same garbage connection and the same garbage problems. I've been through countless different versions and every single one has the same issue.

Why can't you specialists pin-point this issue? Buy a notebook with your card and try using it for a day! Try playing real-time strategies or even try visiting a website! It's so frustrating to have to deal with this issue every single day I use my notebook.

I bought the MSI GS70. I was so excited because MSI makes a quality product and only uses quality devices in their notebooks. I saw all the specs and thought to my self that this would be a very good investment. And for the most part it has!

Except for this garbage, garbage, garbage (I can keep saying it!), GARBAGE network card.

I've tried so many different scenarios and so many different configurations that I'm truly at the end of my rope.

If it weren't for this notebook being sealed (and losing my warranty if I open it) I would have bought another card months ago to save me this stress.

So Intel, what do you have to say about the countless complaints and countless issues with this device. Don't tell me "it's a work in progress" because obviously there is no progress. If you actually tested your cards before releasing them to the general public, you wouldn't have these issues and potentially ruin your reputation as one of the largest technical firms in the world.

Not that that'll happen, because I'm just a small guy in this world and this device is just a tiny part of the technical industry.

Resolved: Intel Wireless-AC 7260 + ASUS Wireless-AC1900 router = FAST

Using an "AC" router I am finally able to get expected 100+Mbps speed from the Intel Wireless-AC 7260 wifi card. T-mobile provided me with a fantastic free ASUS (RT-AC68U) Wireless-AC1900 router through their "Cellspot" program.

Lenovo tech support did a remote session into my machine and updated all the network drivers and power managements settings (again) but was unable to fix the issue. The hardware support desk (great people) then referred me to the software support desk who tried to convince me that the T440s was completely incompatible with any 5Ghz network. Obviously, that is not true.

I still do not know where the limitation lies. Either the Intel AC 7260 is a defective design and is not fully backwards compatible with wireless-N. Or perhaps the Lenovo drivers are bad? Or perhaps it is a Windows bug? At this point I can only tell you all that for me the AC router solved the problem.

I am pretty sure that the fault will be found to be with the adapter itself, and probably not solvable by a driver update. I have been having the same issues as many others. I have a Toshiba p55w and the WiFi works great in the same room as the router. I do have an Lynksys e4200, and it is not AC compatible. The router cost me a lot of money two years ago.

What I have noticed is that the Wifi works great in the same room, but put a wall in the way and performance drops rapidly. On the 5ghz band, I can put a wall in between me and the router and maintain performance, but the 5ghz signal doesn't travel far. For me it is not dependent on signal strength, as you can see in the posted pics.

Picture one is same room. Picture two is bedroom (which is really close to the router, but has a wall in the way). Ping times are great on each test. Signal strength is maximum on each test. The laptop is connected to the 2.4ghz band. I have tried all the workarounds, settings adjustments, and have tried the Microsoft and Intel drivers (all versions). And notice how only download speeds seem affected?

This just sucks. Sure I could fix the problem using only my 5ghz band at home, but I cannot use it at work (older router, access point down the hall) and hotels are a miserable experience. I do have a USB WiFi adapter that makes the laptop usable, but I shouldn't have to have a two inch stick sticking out the side of my 1000 dollar laptop.

Unfortunately Intel does not want to take responsibility.

I'm stuck with using a mini router as a wireless client and connect the ethernet to the LAN port of my notebook (because the company that made that port actually cares about their product). While the crap Intel garbage is stuck to being just a Bluetooth receiver (I'm surprised it actually works).

Next time I think about buying anything Intel, I'm doing my research.

I will be telling people about this product and the lack (most people would say none) of customer support for the thousands of people affected by their negligence.

The little man will prevail.

Sounds like defective card or that the antennas are loose or aren't firmly attached to the card. I get all of my 100 Mbps all the time with 2 walls in between the router and Intel 7260. Try opening the case and check for antenna.

Veterans,

You raise a good point. Since there is a very solid "click" when the antennas are snapped into place, and I'm guessing there wouldn't be anywhere near this number of detached antennas. That being the case, Intel should be accepting back all of the defective cards at this time for hopefully fully tested next rev. hardware.

theveterans, have you tried checking the consistency of your connection? For example, open two command prompt windows. One to ping Google's server, 8.8.8.8 and the other to ping your gateway (for me, 192.168.0.1). Make sure to set the number of times to ping to a high number and the timeout to something like 60 seconds. For example, 'ping 8.8.8.8 -n 99999 -w 60000'.

Do this and try streaming Youtube, watching netflix, playing an online game or something else that requires 100% connectivity.

As an added stress test, try streaming music from a bluetooth device at the same time. When I do all these things, I get ping times of 50-50000ms from my notebook to the gateway, which should always be either 1ms or <1ms.

Clowngod, if this is the case, someone like me cannot open my laptop as it is sealed by the factory. If I break the seal, I void my warranty. I have 16 months left so I'm not doing that.

In that case you should be able to return the entire laptop as the wireless connectivity is non functional. Maybe (depending on the manufacturer) there's a spin of it using a Broadcom or Atheros card?

I probably would, but is it worth my time and effort? No. Intel should have released a working adapter. I'm not about to send a notebook which I use every day on a 14 day turnaround to possibly or not possibly have the adapter replaced with something functional.

Of course it would increase latency no matter how good the adapter. It's the nature of WiFi and QoS. I believe that the more consistent packets you send over the air, the higher the jitters will be. Also, WMM QoS would be a huge factor here as it will prioritize streaming packets and put the round-trip packet pinging test to a low priority. However, even with increased latency of least prioritized command prompt ping from 1 ms to 20ms with spikes to 100 to 150ms, there should be minimal network lag experience on the high priority packets like YouTube, DLNA video/music streaming, gaming and VoIP. Yes I get the cmd ping spikes to 100 ms on pinging gateway test when doing multiple activities such as multiple streaming while downloading but I never buffered nor have interruptions with my local NAS streaming, YouTube/Netflix/Silverlight streaming when doing multiple things at once. Spikes of 50000/ping timeouts are not normal at all, I think the router might also cause this interruption. Try performing the same stress test on another device with Atheros or Broadcom wifi and see if you get ping timeouts. If both get the same results, it's the router.

Ah right ahead of you:

I have no proof at this moment in time, but I have tried these tests on another laptop with a different card. The other card would get spikes between 1-200ms but it didn't cause any interruptions. My laptop on the other hand had spikes of 0.01s to 25 seconds at a time (most of the pings would timeout for a few minutes after if they were bad enough). It basically halted internet connectivity. I tried turning off bluetooth at first, but it does nothing. This has been happening since the beginning of time with my notebook but it's only now that I can actually see it happen in front of my eyes.

Sudden, infrequent irregular spikes to 100-200 ms is normal for WiFi, but what's not is when this affects whatever application you're working on currently. Basically, when there's a packet loss, or latency above 300ms, that's when live streaming gets interrupted. You do have wifi adapter problem being erratic. Some people here have noted that replacing the adapter with the revised version fixed their problems though. Then again, it's unreasonable to open up a brand new laptop for a WiFi antenna check/Wifi card replacement.

I too am experiencing many of the issues discussed in this thread. I created a thread describing my issues before reading this one but thought I would chime in here too. I have two laptops running two different Linux distros (with different kernels and different firmware versions), both have the 7260 card and both have all the issues described. I have two different APs at home and the issues occur on both APs. I have another laptop running an Intel 6205 card and that laptop has no connectivity issues. I really, really wish Intel would fix this card. The wireless is entirely unreliable.

theveterans,

This is exactly my point. It's unreasonable why this is happening. I didn't think it was like a reputable company like Intel to make such a mistake and completely overlook these issues before releasing a card. It makes me doubt Intel and makes me very weary of what I purchase from them in the future. Not only that but when someone asks me what I think of Intel from now on, I will have nothing good to say because of these experiences. It's even worse that they refuse to help or even troubleshoot their own device.

I'm disgusted right now and wish I had the opportunity to exchange my card for another company. I hear the Qualcomm Killer-N 1202 is an excellent replacement card. Only about $45 on eBay as well. Once my warranty runs out on my notebook I will be removing this card and burning it. Total garbage.

kas,

With all the attention this card has already, and the amount of threads being created, I highly, highly doubt anything is going to happen.

Hi mpelley92, you got me thinking about the Qualcomm Killer N 1202 card. As far as I can tell, however, that card is mini PCI-e, so I don't think it would work with my laptop (mine has the AC 7260 M.2 NGFF). Also, I've heard that some laptop makers whitelist the wifi card hardware, making it impossible to replace your wifi card with anything but what is supposed to go in there. I don't know if Toshiba does whitelist, but from what I understand they do.

I thought about getting the AC 7265 M.2 to try and see if it works better. Unfortunately, there are so many different models I am at a loss as to which one to get. This really sucks.

And no theveterans, it isn't a lose connection. Too many people have this issue for it to be a lose wire. It's a broken wifi card is what it is. And now I'm stuck with a thousand dollar laptop that won't connect most places (except at unusable speeds). Heck, I even went back to Best Buy to speed test the display laptop. What do you know, less than a MB/s....NOT HAPPY.

Combination of poor drivers and wifi card quality IMO. I believe the early April 2013 7260 cards are the best batches since I never experienced problems with it under Windows 7, but did have an issue with windows 8.1 so it was a driver problem for me. I was able to fix it though with zero power saving on pci express.

FYI, Killer N1525 is NGFF, not mini pcie like N1202 and it's a good alternative to 7265

theveterans,

Thanks for the information on the n1202 card. I can't find them for sale yet, although I do see where they are used in several newer laptops.

I took you advice and opened up the case and looked at the WiFi card. Leads were firmly attached, and even had black tape over them to keep them tight. Also, I am not sure, but the card that is in my Toshiba looks different than the pictures of the N1202 card on Google. I'm going to look more into this. The unusable WiFi is killing me, especially at work. At home, I just use the 5 ghz band and don't have too many problems. But at work, my connection is unusable unless I use the USB WiFi adapter I bought. I am just afraid I'll snap that little stick off one of these days...

Found a solution to limited connectivity/adapter power problems. This completely fixed the problem for me. I can now use wifi after sleep mode even when moving locations to different wifi signals.

Device Manager -> Network Adapters -> AC 7260 -> Properties -> Power Management -> Uncheck both "Allow the computer to turn off this device to save power" and "Allow this device to wake the computer"

Haven't had a problem for 2 weeks. I'm a student who uses my laptop regularly.Oh and,

Screw You Intel.

I only wish it were that easy for me. Seems Intel put out (an apparently very large) batch of bad hardware where regardless of power settings, APs, or anything else they can't stay connected for more than 30 seconds to a minute. Intel of course has not offered to replace the bad hardware, so in that case it's "Intel screwed us".
