DualBand 8265 ac: Max 10 MB/Sec, Windows 10


I´ve bought an 8265ac and my speed is limited to 10 MB/sec. That´s disgusting. I´ve been searching for a long time to find out that my driver in the "Geräte-Manager" (device manager) has no "ac-mode" and is only limited to to modes "802.11a/b/g". So i set the preferences like the recommended setting from the forum but no difference.

Is that a limitation of windows 10?

Hello Carlos A.

at first i checked the compatibility of my mainboard to the high level 8265ac adapter. Sure, there will be issues like new driver and so on. SiSoft Sandra says the Wifi is working in low powered level like energy saving mode. I checked the BIOS and the device manager. There i stopped any power saving modes and searched in the power savings for a issue like that. There is none. The last adapter i´ve got was an Intel 6xxxx Wi Fi there was not an issue.

Hello cclever,

As per the logs provided, your wireless adapter is using the correct settings.

However since you were not connected to a wireless network at the time that the SSU was ran, we were unable to find out whether your adapter is connected via 802.11n, ac, or an older standard.

Even if your wireless antennas where not connected properly, should still be able to achieve connection rates higher than 10 Mbps.

Unfortunately, when it comes to wireless adapters it is not as simple as one might imagine. It's common for customers to replace an OEM adapter for the same model but not purchased through their OEM, and then experience compatibility issues. Which is why this issue is not supported.

When it comes to the http://ark.intel.com/products/94150/Intel-Dual-Band-Wireless-AC-8265?q=Intel%C2%AE%20Dual%20Band%20W... @ordering Intel® Dual Band Wireless-AC 8265 there are 7 different versions, and that's without accounting for modifications made for each OEM. It's possible that yours may be a low power version, and your system may not be able to communicate properly with the adapter.

Since you're already using our latest Intel® PROSet/Wireless Drivers, perhaps you could try installing the latest drivers, without any additional software:

1. https://downloadcenter.intel.com/download/26469 Download Intel® PROSet/Wireless Software and Drivers for IT Admins, 19.20.3. Windows® 10 64-bit: Wireless_19.20.3_Driver64_Win10.zip


2. Extract the contents of the zip file to a known location in your drive.


3. http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005587.html Uninstall PROSet. When prompted, choose the option to "Discard settings".


4. http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005756.html Uninstall Wireless driver from Device Manager. Make sure you mark the option to "Delete the driver software for this device".


5. Go to Device Manager and locate the 8265 (it may be an unknown device at this point), select the option to install the driver and browse to the location where you extracted the driver files.

However if this still does not resolve your issue. Our recommendation would be to purchase your next wireless adapter through your OEM to ensure full compatibility.

Best regards,


Carlos A.
