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...

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... 😄


*high five*

Right now im getting back my 10Mb/sec
Honnestly i can't tell you which one i have, i don't even know what N or AC means..

Maybe i talked too quickly.
I'm not sure yet, that's strange cuz i downloaded a game (Uplay) and it was like my wi-fi was fixed but my others dl still are very slow.
I used to dl large files (3D movies, games, etc) using Jdownloader2 at 1Mb/sec but now it's more like -50kb/sec..
I tried to dl a driver from Nvidia just to make a test > 200kb/sec., watching 1080p60fps video on YT > Pain in the ass so i'm pretty confused
Even by plugging RJ45 cable, there's not big changes. Maybe it is simply my internet provider but that's would be a BIG coincidence that Orange decide to get probs the week i get my G751JY.
Ill try something tomorrow, i'll try to dl exatly the same file with an other computer but im not optimist ... i already know that all ROG on earth want me dead.

I have not found QoS section in my routeur settings but i found it here:






Maybe i was wrong to do things this way?

Cédric, WMM needs to be enabled on your router too, look in all the areas with Wireless settings - Wifi setup, Wifi Advanced, Advanced, etc.

What make / model of router are you using? Have you updated the firmware? What version is the firmware?

You need to be using WPA2/AES encryption on the router and of course on the laptop. Find the HT setting in the Wifi adapters properties, should be in the same list you found the WMM setting - set to HT for 802.11n and VHT for 802.11ac, you might as well set it in VHT even if your router doesn't do 802.11ac, as you might come across one elsewhere when mobile.

When making adapter properties settings, it is a good idea to reboot, even though the adapter resets after changes, it doesn't hurt to reboot after making the changes - to make sure everything comes up and works as expected at boot time.

150mbps indicates you are running 20mhz single channel Narrow mode, and not 40mhz - dual channel (20mhz) bonded channels. Change from Auto to 40mhz in the router if you can't get it to automatically switch to 300mbps 40mhz bonded 2 channel - Wide mode.

Also, in the US we have 2.4ghz channels 1 - 11, with 6 as the normal default center channel. If you have the same range, try manually setting the center channel to 1 - do some performance tests, then switch to 11 - and run the same performance tests again - I use speedtest.net here and try test nodes north and south of my location.

If you want to get fancy you can use Wifi Analyzer on Android, and inSSIDer on the PC to look at where your Wifi 2.4ghz neighbors center channels are, and then pick a center channel that puts your signal in the clear as much as possible - to reduce interference.

Hopefully your area won't be that crowded, but you won't know until you look 🙂

On a basic router I run without QoS and without other packet processing - just the firewall is on - because at 50mbits/sec or greater it will slow things down. At 120mbit/sec internet speed the throughput drops about 18mbit/sec with all the deep packet inspection. Make sure your firewall is on, both on the router, and on your PC's.

Take it slow and take notes, google if you need to when you find things in the router you don't understand - some routers will have built in help with short descriptionss - google has more details.

How fast is your internet Download/Upload?

Where are you located? You might want to set your DNS in your router to a DNS provider other than your internet provider, I switch around between a few in the US, especially if I get glitches or lags - as I have everything tuned for maximum performance so if something slows down or lags I know it isn't my stuff 🙂

And, remember, this is all supposed to be fun 🙂

I believe that you also need to enable HT mode otherwise your card won't connect to the "n".

Thank youSati747 and hmscott as always thank you for your complete reply, i'll try to answer the more clearly i can.

Trust me i looked in every area i had access (as admin) and i cant find a QoS section, i can send you some screen if wanna check.

My router is a LiveboxFTTH v2 from Sagem and i never updated the firmware, here's te version: SG20_h323-fr-4.33.5.2

I'm using WPA2/AES encryption on the router but i can i know for for the laptop? About HT/VHT it set on VHT by default, so should i change it or let it this way?

I'm actually looking in the router settings but i can't find any places where i can change Auto to 40mhz.

Here's my internet download/upload speed: 10267 Kb/s/1020 Kb/s

I'm actually living in Reunion Island, a little island in Indian Ocean. Take a map look just right of Madagascar and u'll see a little thing in this blue, yep that's me.
I never changed my DNS and a lot of settings, as I told you before, im not really an advanced computer user.

Cédric, it isn't necessarily in the QoS section, that is what I tried to explain above. Here is a router with the WMM setting in the Advanced Wireless section:

43605

Here is where to set the Channel Width settings for 40mhz, 20/40mhz, and Auto 20mhz/40mhz on that router, and set 802.11n only, and manually set the center channel - 6 here, all in the Setup, Wireless, Manual Setup area:

43607

Leave the VHT setting set to VHT.

WPA2/AES is set by the router, the laptop adapter negotiates with the router and uses the same protocols - otherwise it wouldn't connect 🙂

If you have no Channel Width settings available, it might be a fixed Narrow 20mhz radio. Which means the most it will do is 150mhz, so you are done 🙂

I will check around, I need to translate and read.

Do you have a link to an English manual?

I can't find it in english, im still looking for it

Is this what the configuration looks like?

https://josemanuelsp.wordpress.com/livebox-2/manual-sagem-livebox2-orange/

I don't see any Channel Width options.

Do you have a specifications page for the router we can look at? It might only be a 150mbit/sec connection... 300mbits might not be possible with this router.

Here are the newer Sagem DSL gateways, all the way up through a new 802.11ac Wifi unit - but unless you are sharing stuff on your local LAN, your internet speeds aren't high enough to require more than 802.11b/g, even N is way faster than your Down/Up speeds require.

I think you are good at 150mbps 🙂

It looks like there isn't such area like this, i checked all area i could.
