Dual Band AC 3165 download speeds limited to 30 Mbps

Jump to solution

I am unable to get wireless download speeds greater than 30 Mbps on my Dell laptop with the Intel (R) Dual Band Wireless-AC 3165.  My service provider used a 5G phone to connect to my network today and reached download speeds of 120 Mbps.  So he says it's my network card. I have reached 45 Mbps using my cell phone on my 2.4 G network, but nothing over 30 Mbps (and frequently lower) using my laptop on 5 G. Would appreciate any help.

Here is my SSU scan for the network wireless settings:

Hello DebbyG,

Thank you for your update.


In this situation I would recommend the following:

  1. To determine that this is not a problem with the network, testing your laptop in another network would be recommended. Then, we can compare upload and download speeds between both networks.
  2. In terms of software such as drivers, we can determine that the computer is using the latest drivers that are validated for the device. As a recommendations for the future, I would strongly recommend to download of any driver/firmware directly from the laptop manufacturer. Hopefully a future release may resolve this behavior.
  3. To ensure top performance, I would recommend checking with your router manufacturer for any firmware or configuration to perform on their side to ensure proper functionality of the device.


The use of an Ethernet connection will increase both speeds in case you are interested.


I hope this final recommendations help to answer your concern.

Hello DebbyG,

Thank you for posting on the Intel® communities.

I understand that you are experiencing some download problems with your wireless adapter. To better assist you please provide the following information:

  • When did it start to happen? Was it working fine before?
  • Do you remember if this issue happened after a new OS update or Wireless driver update?
  • Please provide the model of your laptop
  • Is this the original adapter that came pre-installed in your system or have you changed/installed a new adapter recently?
  • Have you checked if this behavior occurs on different networks?


Also, I would appreciate if you could attach the complete SSU report to the thread so we can have more information about your system.

This laptop was bought new and has always gotten download rates between 25-30Mbps (before any software updates).  I initially thought it was a service provider issue. All hardware is still original.  It is a Dell Inspiron 13-5378.  I have not tested it on another network, but I have tried a different laptop on my network.  A Dell Inspiron 15-5378 with a Qualcomm QCA61x4A 802.11ac adapter gets 278 Mbps download on my network.

I've attached the full SSU report.

Hello DebbyG,

Thank you for your response and the information provided.


After reviewing the SSU report, I noticed that you are currently using an outdated wireless driver and also your operating system can be upgraded to a later version.

I consider those steps are important to ensure top performance in your device.


First, as you may know, when talking about laptops it’s worth mentioning that Intel provides generic versions of software and drivers. Your computer manufacturer may have altered the features, incorporated customizations, or made other changes.  

I would recommend the installation of the drivers provided by your laptop manufacturer, in this case DELL*. You can find them in the following link.


In case you have more questions about the OEM drivers, the customizations performed by DELL* or guidance in their website I would recommend checking with DELL* for further assistance.


Please let me know if you notice an improvement after the installation of the driver to version: 21.70.0.6.

I did update the wireless driver to the Dell version 19.51.27.1 (as opposed to the Intel 19.51.27.1 that was already loaded).  This did not make any difference to the ~25 Mbps download speeds.  As Windows 10 version 20H2 was only released last month, and I have had this issue for a long time (thinking it was a service provider issue), I highly doubt that this version is going to suddenly increase my download speeds.  The other Dell laptop I have tested has the same Windows 10 version as my laptop and it is lightning fast with the Qualcomm network card.

I was hoping you could see something in my network card settings that I could change, but apparently they must be ok.  Or whether there was some developer type commands to communicate directly with the network card, as I believe there must be something at the firmware or hardware level.  Since my warranty is long gone, unless you have something else to suggest, I will have to live with it until I get another computer or brand of network card.

I owe you (Esteban) an apology.  I really didn't think updating to Windows 10, version 20H2 would help.  However, I did do the update yesterday (it took more than 12 hours to complete!).  I am now getting download speeds of up to 230Mbps!!!  My upload speeds are only 16Mbps, which is still slow.  But obviously I am very happy with the download speeds.

Hi Esteban,

My internet service is supposed to be download (up to) 300Mbps and upload (up to) 100Mbps.  As I first noted, they did come out and test my system and showed I was getting close to those speeds. 

Now, with your help, I am getting the correct download speed, but my upload of 16Mbps is quite slow.  I don't upload a lot (photos sometimes), but if there is anything you can think of that might improve that, I would appreciate it.  If not, I am still very pleased to have much better download.

Thanks!
