My Intel Dual Band-AC3165 adaptor is not giving me the speed my service provider recommended. I do get only about 60 - 70 Mbps. I checked with another laptop and the speed I do get is over 150Mbps. The service provider suggested that I contact INTEL

[DHema]

I have run the Intel System Support Utility and the report is attached.

My wireless router is Linksys EA9300

Thank you.

Hello DHema,

Thank you for submitting your question on this Intel® Community.

Based on the report atttached, we found the following information:

• BIOS is outdated.

According to Dell, there is a newer BIOS version: 1.1.3. Updating BIOS may address this issue. We recommend that you contact your Original Equipment Manufacturer (OEM) to obtain further instructions.

Links to third party sites and references to third party trademarks are provided for convenience and illustrative purposes only. Unless explicitly stated, Intel® is not responsible for the contents of such links, and no third party endorsement of Intel® or any of its products is implied.

We recommend that you check Windows* updates, scan and apply all of them.

• Make sure both the wireless router and your computer are using the same Wi-Fi standard and configuration.

We recommend checking the Recommended Settings for 802.11ac Connectivity.

• Check if the Power Options are set to Maximum Performance.

Hello DHema,

Thank you for your response.

• What is the laptop model that it is not experiencing this problem? Does it have an Intel® Dual Band Wireless-AC 3165 installed as well?
• How are you monitoring the network speed? Are you able to attach screenshots of the tests you perform?
• Have you tried connecting only your Inspiron 15 Gaming 5577 to the router/AP? Does the performance improve?

Hi Wanner, Here are the answers for your questions: * What is the laptop model that it is not experiencing this problem? Does it have an Intel® Dual Band Wireless-AC 3165 installed as well? It is an HP Z-book with a Intel Wireless – AC9560 160MhZ adapter * How are you monitoring the network speed? Are you able to attach screenshots of the tests you perform? Just used https://www.speedtest.net/ Screen captures are attached * Have you tried connecting only your Inspiron 15 Gaming 5577 to the router/AP? Does the performance improve? No Thank you so much for your help. Best regards, Don

Hello DHema,

Thank you for your response.

Depending on the bandwidth, having more connected devices to the network may decrease the throughput (speed), which may result in lower download/upload speeds.

The throughput can be calculated in the following way for the Intel® Dual Band Wireless-AC 3165 Wireless Adapter.

• Go to the Intel® Dual Band Wireless-AC 3165 product specifications and check the "Networking Specifications".
• The maximum data rate for 802.11ac 1X1 is 433 Mbps.
• Now, (max data rate ÷ 2) ÷ number of connected devices = Max throughput (speed).
• In this scenario, (433 Mbps ÷ 2) ÷ 1 client = ~216.5 Mbps per client.

This is important when comparing the speed other devices are showing since they may have other networking specifications > Intel® Wireless-AC 9560

Now, it is worth mentioning that networks are affected by all kinds of limiting factors including distance, obstacles (e.g. walls), interference, environment, etc. This also depends on the channel width configured: 20, 40, 80 MHz, etc.

Having said that, it is not clear if you have got 150 Mbps of speed or more while using your Inspiron 15 Gaming 5577. If you use this laptop at work, the speed you are getting is most likely expected behavior taking into account the number of devices connected at the same time in these types of environments.

We would like to know if you have got better speeds before when connecting only this device at your office or home.

Also, it seems that the screenshots were not attached to the thread. Try attaching these files directly on the thread.

Hi Wanner, Since I noticed low internet speed compared to the DELL laptop, I placed both laptops at the same location in my house and checked the speeds one after the other. I have performed this test so many times and I always got ~50% less speed in the DELL. I also tested with only the laptops connected wirelessly, but not much change. Here are the screen captures: DELL: HP:

Hello DHema,

Thank you for attaching more information to this thread.

First, it is worth noting that throughput (speed) is not the same as Download/Upload speed. Online speed tests will generate a small amount of random data and measure the time it takes to upload it to (or download it from) the web server. This result will be displayed in bits per second.

Download and upload speeds will be affected by the capacity of your wireless access point, computer's networking specifications, bandwidth (ISP), user congestion, network overhead, neighboring networks using the same channels, etc. In other words, wireless networks do not perform anywhere near the maximum data rate product/ISP marketing advertises.

If your computer is running with the latest Windows* 10 updates and Original Equipment Manufacturer (OEM) drivers, then what we can recommend is that you contact your OEM for further support and warranty options in case a similar system (i.e a computer with an Intel® Dual Band Wireless-AC 3165 installed) performs better in the same network environment. 

Also, we recommend that you contact your router/access point manufacturer to make sure it is running with a configuration that can benefit systems with different networking specifications. Besides, they may install a new firmware update for your router/AP if available.
