Wireless-AC 7265 5GHz not working in windows 8.1

Hello

Running Windows 8.1 (x64), tried drivers 17.13.11 and 17.1.0. The problem is, i cannot see any 5GHz networks using windows list of wifi networks or SSID scan tool (inSSIDer). I can see multiple SSID's including my own on the 5GHz band on my other devices. I just got the 7265 card yesterday.

I have tried a bunch of things, including a fresh install of windows and the stuff in the support section on intel website (adapter settings for optimal performance etc). Nothing works!

netsh says my card has "802.11a" and "802.11ac" capability in windows, which seems fine.

It almost seems like there is something turning off the 5GHz radio on the card in windows.

Since the card is new, i thought there might be a hardware issue, i.e. 5GHz radio broken.

However i tried booting from a linux live USB stick, in this environment i can see 5GHz networks, i can connect to my own 5GHz network and i get AC link rates (400-800mbit) and high transfer speeds (100mbit+). This was on ubuntu 14.04LTS. So there should be no hardware failure or hardware incompatibility issue.

Anyone have any tips? Is there any kind of power saving mechanism (or similar) in windows that's capable of turning off only the 5GHz radio? The 2.4GHz radio works fine.

Hello Buffler,

Where do you have this adapter installed ? Is it a laptop or a desktop? If it is a laptop what is the model and brand, we also would like to know if you replaced the original wireless card for the new one. Please let us know as soon as possible so we can guide you more efficiently towards the resolution.

I have exact same issue. today I received my Intel 7265 NGW AC to replace the 7260 N on a Dell Inspiron 11 brand new laptop. with prior N 7260 adapter it could connect 300 mbps but this new one only knows 2.4 GHz and connects at 144 mbps only. I changed all the settings to get better but impossible. searching for an answer saw this post and I am happy at least one more person has same issue. my windows is 8.1 64 bit edition. drivers are the latest CPU is Intel N3530 Quad core 2.16 GHz. RAM 4 GB. SSD 240 Samsung 840 EVO.

Hello, thanks for your attention to this matter. It's a Lenovo Y50 laptop, and i replaced the original wifi card for a new one.

It really puzzles me why it works in Linux but not Windows. I would prefer to run Windows.

My windows desktop PC also has an M.2 slot, so I'm gonna try it there and see if it works

Hello NJ, thanks for the information. So we have two different laptops with the same problem. Please update if you solve it somehow.

The same issue occurs when i install the card in the M.2 slot of my desktop computer. This computer is running windows 7 SP1 x64, Intel z87 chipset. Still works fine in Linux.

Hello buffler, scoop, mihnea and NJ,

We can see that you all changed the adapters, correct? Have you all tried to contact your computer manufacturers also known as OEM (Original Equipment Manufacturer) to see what they can tell you whether this integration is supported by their systems? The issue you are experiencing may be caused by the integration. (the replacement of the original adapter) as it has been modified to fit your system. Please keep in mind that wireless hardware installation and use is subject to regulatory approval, and the adapter you installed may not be supported by your system. In this particular case, only your system manufacturer is entitled to provide the list of validated and certified adapters that are compatible with your system. So for more information you may need to check with them directly.

Furthermore, Intel Wireless Adapters for laptops are meant to be professionally installed by OEM on certified systems only. Please it is very important that you take a closer look in the links below as they contain important information.

http://www.intel.com/support/wireless/wlan/sb/CS-031167.htm http://www.intel.com/support/wireless/wlan/sb/CS-031167.htm

http://www.intel.com/support/wireless/wlan/sb/cs-011644.htm http://www.intel.com/support/wireless/wlan/sb/cs-011644.htm

In this case, we will be more than glad to provide you with the latest Intel drivers, these drivers are generic and in some cases, the OEM changes specifications on the adapters and due to this, our drivers may not resolve the issue. In the links above, you will find more detailed information regarding as to why your adapters may not function as expected. Unfortunately, Intel does not support integrations but we will be more than glad to assist you as much as we can and for this, please contact your Intel Support Center found in our webpage according to your country and location.

Let us know if this information helped you.

As long as the wireless card works with linux, it's not a problem with how or who installed the card or if the laptop is compatible with the card. If in linux the wireless card works fine, and in windows it has problem, then it's a problem with the windows drivers, not a hardware incompatibility.

Mihnea,

When a manufacturer gets wireless cards from Intel, they adapt this card to work well with their system and that implies in changes such as voltage, certain features being disabled or added. Also please be aware that drivers compatibility is highly related to the O.S. this means that the driver may be compatible with the laptop and Linux* but not necessary with the laptop and Windows*. And just as you mentioned, this is not a hardware issue, it is a driver issue. Please contact your computer manufacturer to see if the have specific drivers for this adapter in order to work with Windows*.

Well I saw your post and briefly reviewed your links, however there are many logical fallacies - i.e. If there are regulatory issues preventing Intel from creating a working driver, why do they not apply to Linux? Why are wireless radios with user replaceable antennas sold everywhere if they are illegal? Why am I able to use the higher 5GHz channels, which are illegal to use in my country, on my N-7260 card if following regulation is so important?

Note that I don't doubt that you are correct, I just don't believe the stated motives. The thing is, radio regulations apply to radios and the electromagnetic radiation emitted by those radios. So if radio regulations are the problem, why does the iwlwifi driver work? The same regulations apply to iwlwifi.

Intel surely knows how to make the card work, they just choose not to make them work when combined with the products of Intels trusted business partners.

Thanks for the information though, I think everyone understands why it doesn't work now

I just wanted to chime in as well on this issue. I received the dual band 7265 card this week and replaced my dual band 3160 card in my Alienware Alpha this week much to my surprise the 5ghz channel no longer shows up even though the 7265 is a upgrade option from Alienware. It would be nice if intel could get on the ball and actually figure out their drivers.

I also replaced my 3160 with AC 7265 card on Alienware Alpha. And exactly happens the same thing that happened on you: no 5GHz Network shown.

Perhaps is Dell's OEM Windows OS blocked it, I mean it did blocked me from installing the latest nVidia driver by changing the video adapter's name and the driver couldn't identify the model.

@ aleki_intel Any ideas???

Same problem after upgrading a Dell 7347 running Windows 8.1 (64bit). 2.4Ghz working fine but no 5GHz band. Have tried installing/uninstalling/re-installing drivers from Dell and direct from Intel.

Hello 7347user, SCARITTAGLE and Dudusmaximus

We do understand your frustration, but in this particular case that the wireless adapter was replaced, we highly recommend that you contact your computer manufacturers first to see if they have any drivers that can help resolve the issue. Intel does not support integration (which is the replacement of the original wireless card for another one). Only your computer manufacturer is entitled to provide a list of tested, approved and validated adapters that are compatible with their system with no issues. We also would like to inform you that wireless hardware installation and use is subject to regulatory approval and the adapter installed may not support your local regulations.

Furthermore, Intel(R) Wireless Adapters for laptops are meant to be professionally installed by an OEM (Original Equipment Manufacturer) technicians on certified systems only as features may be added or removed, voltage changes... etc.
