After updating my Wifi driver to 20.0.2.3 (2-3 weeks ago), I've twice gotten a blue screen crash on resume from sleep. As this driver version is the first to include the KRACK vulnerability fix, it is not reasonable to roll back to an older version. An inspection of the last memory dump reveals the following:

PAGE_FAULT_IN_NONPAGED_AREA (50)

Invalid system memory was referenced.  This cannot be protected by try-except.

Typically the address is just plain bad or it is pointing at freed memory.

Arguments:

Arg1: ffff8009f4c00000, memory referenced.

Arg2: 0000000000000002, value 0 = read operation, 1 = write operation.

Arg3: fffff80032d896af, If non-zero, the instruction address which referenced the bad memory

    address.

Arg4: 0000000000000002, (reserved)

Hello,

I have DELL 5521 (Service Tag: 50W44Y1) with Windows 10 installed. Recently i have purchased Amazon Alexa (2nd Generation) and connected to laptop by Bluetooth.

Here problem starts, When i try to watch videos from youtube or any other website and listen on bluetooth speaker or on Alexa, wifi stops working. Sometimes it shows

connected or sometime it shows no network. Even wifi on/off button also doesn't work. Same thing i tested on other brand's laptop, on same Wifi network and with same bluetooth

speaker and Alexa, it works. I have updated Windows/Wifi drivers from below links using auto detect tools and it shows your device is already updated with latest drivers.

Dell Inspiron. 3160 sees internet connections, but will not connect - simply says "no internet". I've installed the latest driver. I'm out of ideas. Tried both 2.x and 5GHz settings.

New Linksys Velop network at our house and multiple devices connecting no problem - macbook, iphones, pc Windows 10, desktop Windows 7 BUT my laptop Windows 7 does not connect. Sees the signal but hangs up in authentication.  Wireless adaptor is Intel Centrino Wireless N 2230.  I've updated drivers, deleted all connection profiles, tried static IP,  rebooted 9999 times.  Any ideas welcome!

Hello,

I've recently upgrading my internet connection to 500 Mbps fibre however I've only been able to reach speeds of <250 Mbps on my laptop which is equipped with the Dual-band AC-8265, on AC mode, 80Mhz channel width, 5Ghz band, 99% signal strength, I understand that it could reach a theoretical maximum of 800+Mbps however as I mentioned I'm nowhere near that. I've attached a copy of the SSU text, in which it states the following:

Product Type:"Intel(R) Dual Band Wireless-AC 8265"

                    Profile:""

                    Radio Type:"802.11ac"

                    Receive Rate:"866.7 Mbps"

                    Service Name:"Netwtw06"

                    Signal Strength:"99%"

                    State:"connected"

                    Status:"Enabled"

                    Team Name:"Not in a team"

                    Temperature:

                    Transmit Rate:"866.7 Mbps"

Now I suppose this less than scientific or real world speed testing means little to nothing but when my iPhone 6S Plus is consistently running well above 200 Mbps and as you can see in the attached capture (IMG_0757) hits speeds of over 400 Mbps while the laptop rarely sees speeds of 200 Mbps as you can see in the other attached capture (6754205111) this if nothing else suggests that something is configured incorrectly with the Intel driver, as I'm running the speedtests against the same server, same wifi, same internet connection just moments apart...

now I've made some changes in the advanced driver settings however nothing seems to have any meaningful impact, I'm hoping that someone can offer some insight or suggestion that would help.

I recently bought a Dell Latitude 12-7275.  I also have a new IPhone 8.  When I try to connect the Dell to a hotspot through the IPhone, my Iphone flashes several times at the top and bottom of the screen, and then the Dell gives me a message that it "Can't connect to this network." 

I'm running Windows 10.  The Iphone data is through Verizon.  I have installed all Windows updates.  I updated all of my drivers through Dell, and then I updated my wireless adaptor through Intel.  The wireless adaptor is a Intel Dual Band Wireless-AC 8260, and I have installed Driver 20.0.2.3. 

Please help!

Thanks.

Hi. We have 2 laptops with Broadcom bluetooth chipsets and 2 with Intel chipsets, all running Windows 10, same updates. The ones with Broadcom chip have a "Share" tab on the bluetooth settings; the ones with Intel don't. To send 50 files from a phone or tablet to the Broadcom based portables through Bluetooth  is a breeze. Just choose the files on the phone or tablet and send them all to the computer at once, after they're paired. On the Intel based ones it's a nightmare, as we have to choose for each file to receive it and after that start sending it on the phone / tablet. And repeat this ad nauseum.

Why isn't the sharing option available with Intel drivers and chipsets? It's too painful to use the laptop without it.

Thanks for any help, I've been searching everywhere to no avail.

Hi!

I have a ASUS Zenbook Pro UX550V with Windows 10 Pro. It has an Intel Dual Band Wireless AC8265.

The Zenbook has the possibility to connect an extrenal monitor via a HDMI plug.

When I connect and activate an external monitor (either duplicated or extended or single desktop) the internet access via WIFI is not working anymore. The WIFI signals that a good and strong internet connection exists but internet browsers (different broweser) or email clients cannot acces the internet.

In the windows event viewer there is a flood of System Errors: "Intel Dual Band Wireless-AC 8265: Has determined that the network adapter is not functioning properly. (Source: Netwtw06, Event Id: 5002)"

As soon as I decativate the external monitor the system errors stops and I can access the internet.

I made sure that I installed all Windows 10 updates as well as all driver updates.

How to solve the problem?

Thanks.

Hello. I would like to upgrade the wireless card on my Dell XPS 15 - 9530 and I was looking into the newest Intel AC 8265NGW card. Could anyone please confirm this is doable? Thank you!

Please refer to the following article that provides detail information about support options for discontinued Intel® Wireless Products and the updated list of adapters that have been discontinued.

Hi,

I have a HP-15-au114tx laptop with Intel Dual Band AC 3168 wireless adapter in it. The problem is that the maximum speed for wifi is not able to cross 100 mbps (even though the rated limit is 433 mbps). My connection type is 802.11ac and have a 1-giga-bit plan for internet, but even after this the wireless adapter fails to give speed above 100 mbps.

Please look in this matter ASAP and provide a solution for it.

Thank you.

Hello,

I would like to know if the module Intel Dual Band Wireless-AC 7260 is end of life ? If yes when is the last call for buying ?

Thank in advance

i recently built a computer (windows 10 /64 bit) and put one of these chips in it, and it has detected it but the chip but, won't do any wireless activities, bluetooth, wifi, hotspot. I've downloaded all the drivers i could find for it and reset my network settings, off and on dozens of times, followed a few other support pages, but it still wont work. the last thing i want to do is to have to pull it out as it takes a good hour to dismantle my pc to get it out. but where do i go from here.

its in an Asrock extreme 4 motherboard with an I7 7700k chip, no antennas on the case, although that shouldn't matter

I have an intel ac 8265 wireless adapter and latest drivers installed in my lenovo t470p In technical specs miracast support is present. But I can't connect to my miracast TV (which works perfectly with other devices).

When I get the dxdiag's log it says: "Miracast: Not Supported by WiFi driver". I have the latest Intel driver installed (version 20.0.2.3). What drivers should I use to be able to use the miracast?

I have had to use external usb adaptor to connect to my router. My Zotac sitting on the same desk has no problem connecting to a number of WIFI's, i.e., I dont't think it is a signal strength problem.

Hi All,

I'm observing few of the PC's in my client network is trying to communicate wServoceith a Botnet IP - 208.91.197.27 which belongs to Confluence Networks Inc (US).

When I check with the Process and source of the traffic, surprisingly I found out that, it is generating from the location Intel PROSet/Wireless Zero Configure Service/ZeroConfigService.exe.

I don't know why it is trying to connect to an external IP.

Have anyone of you observed this in your environment, can anyone help me to find out a solution for this?

Thanks in Advance,

Kiran Vyas
