Intel AC7260 problems

[NK5]

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?

No AC but it works a thousand times better than that stupid Intel 7260AC. It is very stable on both bands.

I have no issues lately with 5 band. Do you use AC router?

[BIonu]

I have this model: http://www.tp-link.com/en/products/details/?categoryid=2166&model=TL-WDR4300 http://www.tp-link.com/en/products/details/?categoryid=2166&model=TL-WDR4300

Unfortunately it does not ac...:(

Hello Everyone,

It seems like I have found the answer:

(1) My Mac Address of the laptop is added to my router. This was suggested by other forum member.

(2) Install Intel driver 16.8.X.X by going to the following site:

[BIonu]

I installed the latest driver 16.10. There's nothing new, going as badly as before. Good job Intel !

Same thing here. Updated from the 16.8.0.6 drivers from Gigabyte but still have the same periodic "limited connectivity" issue in Windows 8.1 with the AC7260.

Hello All.

I am having similar issues. Ordered this card replacing an intel wireless n 1000 card in my ASUS UL30VT (win7 x64). I just wanted 5ghz band and wireless AC I have tried these drivers:

16.10.0.5

16.6.0.8.

Same result. High latency, wont reconnect after system resume or hibernate. These are junk drivers. Please help us out Intel. There are too many users with different machines across the board that are having the same problems.

Are you using the latest firmware on your router?

[TSliw]

My AP is a 4th generation Apple Airport Extreme (model MC340LL/A) running firmware 7.6.4 which is the latest for the series. I have a 2009 macbook using a Realtek 802.11n card which is connecting at 5GHz with absolutely no issues. I also have an LG Nexus 4 on the same 5GHz WiFI link and have seen no problems.

[AKule2]

Yes. I have tried my 7260 with a multitude of different routers with the same issue. Went back to my centrino wireless N 1000 card and the problems went away immediately. Not exactly the solution I was looking for. Really disappointed with the 7260 and intel driver support.

[BIonu]

Be sure you all have problems with our router .... wireless LAN Intel has no problem, right? That's the solution when a producer is not able to sustain a product of theirs?

[BMatt3]

I have a Dell Latitude E5540 with the AC7260 that is also having latency issues no matter what driver I try or router that I connect to.

[LG4]

I'm running Dell E5530 with AC 7260 and Netgear R6250 AC router. I haven't had much trouble with the last 2 sets of drivers. Currently running 16.10.x I can say that installing drivers and the ProSet utilities is more stable than just drivers and let Windows manage connectivity. I still have degraded 2.4 band performance. Also it is known issue with Intel cards and beamforming on the router. http://www.intel.com/support/wireless/wlan/sb/CS-034535.htm Intel� Wi-Fi Products — TechNote: Sporadic wireless disconnects caused by data reordering issue

I've got the latest drivers on windows 8.1 for the desktop version of this card, and I'm getting bad latency spikes every ~1min or so. Latency is usually about 5ms but shoots up to 200ms for a few seconds then back down. Any fixes?

[BIonu]

I installed the latest driver 17.00. There's nothing new, going as badly as before. Good job Intel !!!!!

[LG4]

I have been running 17.x version and it seems to work ok. I do have problem getting 300Mbps connection,but I was getting it with latest 16.x version drivers.

Any idea @Joe_Intel?

Thanks

[Jose_H_Intel1]

It is possible this throughput issue will be fixed with 17.0.2 soon. We have identified a similar issue.

[MS9]

There's some huge issues with 17.0. I'm on a Dell 7537 and I used to use 16.6 and 16.10. After 17.0, when sitting my laptop next to router, I received barely 3mbs. On a wired connection, I received 6mb.

As soon as I uninstalled 17.0 and ran the speed test, it jumped up to 5-6mb.

I have no idea how a driver can slow down hardware the way this can.

I'm reinstalling 16.10 to see how that goes.

[JMcKa]

I am also seeing the jumps in latency every now and then, which interrupts streaming live TV from a HDHomeRun through a Fritz! Box 7390.

It used to work fine on my 2820 NUC with its stock 7260 card. After replacing it with the dual band version, I am experiencing this fault.

A dual band Netgear USB adapter behaves just fine.

[JMcKa]

I have completely removed the Intel drivers for this card and started using the Windows 8.1 Inbox drivers. At this stage it seems that my issue is solved. I will do more testing tonight

[AKule2]

What driver version number are you using? Can you list the version that comes with windows 8.1? I am running windows 7x64 and tried the latest intel driver 17.0.0.34 and still have latency spikes on either the 2.4 or 5.2 ghz band when pinging my wireless router....
