Intel Dual Band Wireless-AC 8265 - Bad transfer speeds


just bought a new dell inspiron 15 7000 and all is good beside the download speed at about 1/3 compared to my 6 years old precision.

Hello slav2103,

We understand you're not getting the expected download speed on your new laptop using the Intel® Dual Band Wireless-AC 8265.

Based on this report we can see the following:

1. You're connecting to a single band, Wireless-N (802.11n) router (VTech NB403*).


2. Wireless Band: 2.4 GHz, Channel 11, Channel Width: 20 MHz.


3. Connection rate: 180 Mbps, 83% signal strength.


4. Intel® PROSet/Wireless Software Version: 20.30.1

The maximum connection rate for your adapter using a Wireless-N router is 300 Mbps. However, this would require you to use 40 MHz channels, which is not recommended in the 2.4 GHz band due to the limited number of non-overlapping channels available, and may increase RF interference.

Since your computer is new, it's possible that your download speed tests are being affected by your operating system downloading updates in the background. Keep in mind Windows® 10 does this by default.

In theory, the maximum download speed you can expect is roughly half of your connection rate numbers. Speed tests don't account for network overhead (encryption, routing), user congestion, radio interference, etc.

In this case, our main suggestion will be to upgrade to a Wireless-AC (802.11ac) capable router, preferably one that is dual band. In Wireless-AC, your maximum connection rate goes up to 867 Mbps, as opposed to 300 Mbps in wireless-N.

We can also suggest to try manually choosing a different wireless channel on your router and see which behaves best in your environment. Channels 1, 6, and 11 are the recommended channels for 2.4 GHz band as they don't overlap.

You may also want to make sure that your router is placed in a central location, with as few obstacles between it and your computer as possible.

There is also a new set of Wireless and Bluetooth® drivers available for your adapter:

- https://downloadcenter.intel.com/download/27622 Intel® Wireless Bluetooth® for Windows® 10 Version: 20.40.0


- https://downloadcenter.intel.com/download/27615 Intel® PROSet/Wireless Software and Drivers for Windows® 10 Version: 20.40.0

However, if you don't require Bluetooth®, you may disable this module in order to further reduce the amount of interference with the 2.4 GHz band.

1. Right Click the start menu icon


2. Select Device Manager from the list


3. Bluetooth® > Intel® Wireless Bluetooth® > Right click > Disable.

Please let us know if this helps.
