Intel 7260AC terrible wireless speeds... anyone else having problems?

So, we all know that this wireless adapter has real potential problems, the internet is full of horror stories from people about this card.

I did tests today and am consistently getting download speeds of 30Mbps (out of a possible 125Mbps sustained speed, which I get when wired). My crappy Aetheros adapter in my old Acer PC gets 100Mbps sustained download speeds on 5ghz Wireless N, so it is clear that this wireless card is dramatically and horrendously underperforming. My laptop is placed around 4m from my router in the same room, with little to no interference from anything else, so conditions are ideal.

I have tried multiple channels and settings on my router, and tonight will further experiment with the driver-level power saving features etc to see if something is wrong with the software settings on the ASUS itself.

I heard another guy on another forum telling me to try "multiple versions of drivers until you find one that works better", but for me that 's too random.

So, how are you guys doing with your Intel 7260AC cards? Did you have issues? Any tips solutions you used to solve them? 😄

Regards,

Rich.

UPDATE 20.11.2014

GOOD NEWS GUYS!

Before I left home for work I Googled someone with a similar issue and managed to fix my initial throughput problems.

The solution was this... https://communities.intel.com/thread/47426?start=15&tstart=0

Basically on your router you need to "Enable WMM (Wi-Fi multimedia) settings" in the QoS section on your router settings (mine is Netgear 6300, maybe yours is in a different place).

I now get the full internet connection speed that my Wireless N-equipped laptop gets!

However, what I have not tested yet is if I will get through Wireless AC throughput between my router and my laptop, or if the Intel settings page now states that I am connecting at AC speeds.

However, this is already a BIG improvement! 😄

PS: Please note that this an issue specific to this Intel chipset... all my other laptop WLAN cards are 100% fine without this setting enabled...

Ok, I just did a wireless file transfer to another laptop which is connected by ethernet to my Wireless AC router. I was averaging 19MB/s sustained transfer rates.

How does this seem in real terms, Wireless N speeds?

My adapter still doesn't list Wireless N or AC speeds in the device settings, but these transfer speeds certainly seem higher than Wireless G...

EDIT - Apparently "HT" is Wireless N, and "VHT" is Wirelsss AC in the adapter settings, can someone please confirm?

I'm not very expert, but 19MB/s = 152Mb/s, that is surely Wireless N speed.
Wireless G speed is up to 54Mb/s 🙂

Exactly what I thought... so how do I get AC... *sobs*

Richdog, you might already be connecting at AC speeds, check your wireless adapter in Networking and Sharing Center => Change Adapter Settings, what does it show? Right click on the adapter icon and select Status. If you are connected at AC speed, it will be over 600mbps, like this showing 866.5mbps

43485

That is one of the things about AC speed, you won't fully utilize it unless the sending side can muster up enough throughput to fill the available bandwidth.

Network throughput is limited by disk throughput. Is the other PC sharing data from SSD or HDD? The fastest the server can send data from the storage is the fastest you can share the data. For testing you can use a RAMDISK if you only have an HDD on the sharing side to remove the physical disk bottleneck. Be sure and locally test the throughput of the RAMDISK you use to make sure it is helping - some RAMDISKs are slow.

Here is a good on that has a fully functional trial:

Raxco RamDisk Plus - +5GB/sec throughput in tests.

Let's see your connection status to see how to improve it 🙂

AHhh I'm stupid, how could I not think of checking that? Duh. *slaps forehead*

My connection is at around 650Mbps, and so I think AC must be working.

Thanks Scott, guess I'm fine now and just need to optimizse my conneciton speeds. 🙂

Richdog, cool 🙂

That's the speed you are looking for with the Netgear 6300, for AC1300 = 2 x 650 = 1300!

You might google for the particular chipset in the wifi card, is it Intel 7260 - the specific number and letter extensions are important in determining it's spec. The Intel spec for the top part shows connection of 866.5, roughly AC1750, and the same goes for your router.

I guess I wouldn't waste to much time on it, but if you try forcing wide mode on the router on each band, take out of Auto and set 40mhz on 2.4ghz and 80mhz on 5ghz, that might nail the speed to the max.

But, if that works, check your Wifi Landscape to see how crowed it is, the router might be playing nice and reducing it's bandwidth to avoid local traffic.

On Android I use Wifi Analyzer
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en

On the PC I use inSSIDer, the paid version, version 4, but there is also a free version:
http://www.techspot.com/downloads/5936-inssider.html - free
http://www.inssider.com/#steps - paid product info

And, if it is really crowed, 40mhz/80mhz will be obtrusive to other users, and if your servers won't fill the pipe anyway, you might as well be a good wifi citizen and let the router reduce to AC1300, and then I would reduce power as far as possible to reduce interference to others. I run mine as low as it will let me set it, and I don't have connectivity issues.

This shows my Asus router, ssid dlink, with 20mhz bandwidth on 2.4ghz, 80mhz on 5ghz
43486

And, with 40mhz bandwidth on 2.4ghz, you can see I am walking all over other signals with such a wide band signal.
43487

Hopefully you are without wifi neighbors and you can run at full speed 🙂

No more tuning needed!

Except on the server side, to get you more throughput 🙂


Actually it is AC1750 (450+1300 Mbps) ... so it should be connecting at higher (1300 or over) in an theoretical "ideal world", but more realistically around 900Mbps. I briefly saw it connect at 850, but then it dropped to 650... so I guess I just need to find the best conditions in my room. 🙂

Richdog, refresh the page that post is on, and check it out again, I updated after looking at the router/wifi chipset specs 🙂

If you saw the highest speed connection, your settings are likely ok, but like you say the local conditions might be interfering - check out that other post I have software links to look at the local Wifi AP's - maybe you can take the channel selection off auto and move the center channel on one or both bands in to clear space, away from interference.

Richdog THANK YOU!

Your solution works just perfect!!! Damn i was so frustated with this issue, i just did'nt want to send it back to the seller and being without laptops for weeks, i could commit suicide.
DAMN!! I could kiss you if i could!

Glad to hear it dude! *high five*.

What wireless speeds are you getting now... do you have a Wireless N or AC router?

As for the kiss I'll need a few beers first... 😄
