Regarding speed limit problem in Intel Dual Band AC 3168 wireless adapter

Hi,

I have a HP-15-au114tx laptop with Intel Dual Band AC 3168 wireless adapter in it. The problem is that the maximum speed for wifi is not able to cross 100 mbps (even though the rated limit is 433 mbps). My connection type is 802.11ac and have a 1-giga-bit plan for internet, but even after this the wireless adapter fails to give speed above 100 mbps.

Please look in this matter ASAP and provide a solution for it.

Thank you.

Hello suyashbhutara,

Thank you for these reports. This is what we found:

1st Report (https://drive.google.com/file/d/18MDSLKhKmxmvUTyBRhLfgKIsHNBlC_r-/view%29: https://drive.google.com/file/d/18MDSLKhKmxmvUTyBRhLfgKIsHNBlC_r-/view):

- Band: 5 GHz

 

- Channel: 149

 

- Radio Type: 802.11ac

 

- Connection Rate: 150 Mbps (low)

 

- Signal Strength:"99%"

2nd Report (https://drive.google.com/file/d/16oFHJlZkUCvvQivBjK4UHFiFTReIZMWT/view%29: https://drive.google.com/file/d/16oFHJlZkUCvvQivBjK4UHFiFTReIZMWT/view):

- Band: 2.4 GHz

 

- Channel: 1

 

- Radio Type: 802.11n (legacy)

 

- Connection Rate: 28.9 Mbps (very low)

 

- Signal Strength:"89%"

Based on this, we can recommend the following:

1. Make sure that you're using the latest firmware for your wireless access point.

 

2. Enable WPA2-PSK (Personal) encryption on your network, this will prevent unauthorized access to your network.

 

1. To do this, you will need to engage your router/access point support, or internet service provider for instructions.

 

2. Or follow this article by wikihow.com: https://www.wikihow.com/Add-a-Password-to-Your-Wireless-Internet-Connection-(WiFi) How to Add a Password to Your Wireless Internet Connection (WiFi).

 

3. Based on these reports, the 5 GHz band may work better for you. We can recommend the following changes to your https://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005585.html advanced adapter settings:

 

1. 802.11n Channel Width for 2.4GHz : 20 MHz Only

 

2. 802.11n Channel Width for 5.2GHz : Auto

 

3. Roaming Aggressiveness: 1. Lowest

 

4. Preferred Band: 3. Prefer 5.2GHz band

 

4. Enable channel bonding for 5 GHz in your wireless router/access point settings. The name for this will vary greatly depending on it's brand.
