Hello mifisa,

 

 

Would it be possible to generate a new SSU while you're connected to WiFi, and with your VPN disconnected/disabled?

 

 

In the one provided we were not able to see any connection information, which we will need in order to troubleshoot performance issues.

 

 

Best regards,

Hello mifisa,

I'm not sure why, but this new report has no connection information just like the last.

Let's try something else:

1. In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes.

 

2. At the command prompt, type: netsh wlan show interface

 

3. Please take a screenshot and share it with us.

In this output we should be able to see your current radio type, channel, receive and transmit rates, and signal strength:

Best regards,

Hello mifisa,

 

 

Thank you for running this command. We were now able to extract the following information:

 

 

1. You're connected to a legacy 802.11n network.

 

2. Your computer is communicating with your router at 150 Mbps (connection rate).

 

3. You're using the 2.4 GHz band, on channel 11.

 

 

The Intel® Dual Band Wireless-AC 3165 uses a 1x1 antenna configuration. For this antenna configuration, the maximum connection rate achievable in Wireless-N networks is 150 Mbps, which is what you're currently receiving.

 

 

Meaning that your adapter is performing optimally, and the reason for your slow download speeds (aka throughput) must lay somewhere else. Your current connection rate, minus environmental factors (such as: network overhead, user congestion, distance, obstacles (such as walls), interference, etc) should result a maximum expected download speed ranging from ~13 Mbps on a very congested network, going up to ~75 Mbps.

 

 

For a marked improvement, we recommend upgrading to an 802.11ac capable router. We can also recommend making the following adjustments to your https://www.intel.com/content/www/us/en/support/articles/000005585/network-and-i-o/wireless-networki... advanced wireless adapter settings:

 

 

1. 802.11n channel width for band 2.4: 20 MHz Only.

 

2. Roaming aggressiveness: 1. Lowest

 

 

If this does not help, you may need to adjust your wireless router's settings for Quality of Service (QoS), WMM, or priority access list, depending on your router's vendor. You could also test your computer on a different network to see if there is a difference.

 

 

For more detail on the factors that affect performance when your adapter is connecting at full capacity, you may find the following article interesting: https://blogs.intel.com/technology/2014/06/throughput-stupid/

 

 

Best regards,

I think theres is something else because I have other old laptop computer in the same room and my phone that download at 26 Mbps when my new computer with the wireless-AC 3165 only download at 3.8 Mbps... I feel that it is a software problem... how can I validate this?

Hello mifisa,

 

 

I would recommend testing your computer by connecting to a different network. You could also reset your router back to factory settings, reconfigure your network and connect this PC first, so that it may receive high priority by default.

 

 

If this was an issue with the adapter or it's drivers, then the connection rate achieved would be low. Right now you're getting the best possible connection speed for 802.11n networks with this adapter.

 

 

In Windows® 10, networking is handled primarily by the operating system. But you could test by installing a much older driver. You could also uninstall the drivers altogether and let the OS install it's generic inbox driver. If the performance remains similar throughout this, then it's not a driver issue.

 

 

1. Download and save both our latest, and oldest drivers available for your adapter in Windows® 10

 

1. https://downloadcenter.intel.com/download/26148 Version 19.10.1

 

2. https://downloadcenter.intel.com/download/27309 Version 20.10.2

 

2. Under Programs and Features in the Control Panel or Apps & Features in Windows* Settings, uninstall any instance of the "Intel® PROSet/Wireless Software." When prompted, choose to "discard settings."

 

3. Go to the Device Manager > Network Adapters > Right click on your Intel(R) Dual Band Wireless-AC 3165 and uninstall it. Make sure to select the option to "Delete the driver software for this device."

 

4. Clear out your temporary files: Press the Windows* Key + R to open the run box. Type Cleanmgr.exe and press OK. Here you will need to make sure Temporary Files are checked, you may uncheck everything else (unless you're ok with the extra wait) and press OK.

 

5. Install the older Intel® PROSet/Wireless Software downloaded back in step one.

 

6. Reboot your computer.

 

 

If your performance does not improve, repeat steps 2, 3, and 4. Then reboot. Windows* should automatically install their generic driver.

 

 

If the throughput is not affected by your driver changes, our recommendation will be to install the latest driver again, and begin to troubleshoot your router next. It is possible for one device in a network to receive a lower priority while others are able to access the full bandwidth.

 

 

Best regards,

Hi, I followed your instructions and nothing happened, so I tried something else, I installed a linux portable distribution and run speedtest.net test in order to discard some software problem and I found that with Linux distribution I get the desired speed... So I think tha the problem is Windows... what do you think? And what can I do?

This is with Linux:

In windows, I get this results: =(

Hello mifisa,

 

 

That's a big difference. There are a few reasons why this could be happening:

 

 

1. Windows® 10 is accompanied by a native antivirus software. The automatic update process involved for both the AV and the OS itself takes up quite some bandwidth while ongoing. This is not needed in Linux*.

 

2. Along with the OS and the Antivirus, there are usually more background processes running in the background in Windows* than in Linux* builds. It's possible that some of these are also stealing away your bandwidth. Browsers, productivity software (such as MS Office®), others, could be updating automatically.

 

3. Browser add-ons such as pop-up and ad-blockers could be slowing down your connection since they filter all content being downloaded. Although less likely in a brand new system, you may also need to consider a malicious infection (adware/malware/etc).

 

 

Again, your adapter is already receiving the expected connection rate for Wireless-N networks, and this connection rate is high enough that you should be able to reach your expected download speeds even accounting for the standard network overhead.

 

 

To troubleshoot, you may take a look at your Resource Monitor > Network to see what is taking up your network resources, although this may not be as simple as uninstalling everything high on that list, some of those may be necessary.

 

 

Another thing you could try would be to reinstall your operating system. Thankfully Windows® 10 makes this very simple with the "Reset" option:

 

 

- https://support.microsoft.com/en-us/help/12415/windows-10-recovery-options Recovery options in Windows® 10 > "Reset your PC."

 

 

Otherwise you may need to engage your computer manufacturer for assistance since it's a new system.

 

 

Best regards,

Good day,

I have a Dell 5567 notebook, it has an Intel AC3165 Wi-Fi board. Internet download speed does not reach 4Mb. At home I have another old HP notebook, which I usually download at a speed of 25Mb. Obviously, the two connected through Wi-Fi.

I have tried everything to correct the problem without finding success. I have contacted Dell technical support, which gave me remote assistance, installed and uninstalled the drivers, without success of having found the solution. I have changed the configuration of the Wi-Fi board, having gone through all the possible configurations, and always obtaining the same results.

What version of Windows do you have? In my opinion the problem started after a Windows update.

Could someone solve it? In what way?
