FAQ

How can I manipulate the power saving settings for Wifi in my Linux environment?

Wifi adapters by default often come up in a power save mode. That is a mode in which the adapter shuts off the network connection in a state of inactivity.

While this is a good way to achieve additional power savings it of course introduces a delay for re-connecting.

To set the mode on or off:

iw wlan0 set power_save on
iw wlan0 set power_save off

To query the current setting issue:

iw wlan0 get power_save

Some systems might require "sudo" in front of the commands to be exectuted.

Jetson TX2 NX Wi-Fi USB is not showing up after a soft reboot

The Jetson TX2 NX does not act the same as the Jetson Nano when providing power to the m.2 slot. The Jetson Nano will automatically toggle PMU_EN, while the TX2 NX will require a manual toggle of the pin in software.

This applies to USB variants, as PCIe variants have a reset built into the PCIe standard.

unknown symbol in dmesg error

On a linux system if the dmesg is reporting an unknown symbol this is usually due to one of the following:

  1. The backports drivers didn't get compiled against the correct kernel.
  2. WLAN, CONFIG_BT, and WIRELESS were not removed from the kernel menuconfig.
  3. backports was compiled with different flags than how the kernel was compiled.

 

Do your Wi-Fi modules provide a temperature value?

Currently none of our Wi-Fi modules support reading a temperature value.

One important thing to make sure before sending in your device to Laird for country, regulatory or antenna testing.

When you have an agreement with Laird to send in your device for testing of anything around your radio you need to make sure your radio can be set to all necessary test modes.

In order to do that please contact the Laird FAE already known to you or write to Laird at "support@lairdconnect.com" to get in contact with us.

Your FAE will be able to help you determine if your device is fit for testing.

How to set regulation domain in LWB/LWB5/LWB5+ with latest release 8.5.0.7 and later release in Linux platform?

(1) By option regdomain

/etc/modprobe.d/brcmfmac.conf

# Sample contents of a brcmfmac.conf file configured for operation in
#  the United States
options brcmfmac regdomain="US"

(2) By device tree

@mmc0 {
  #address-cells = <1>;
  #size-cells = <0>;
  bus-width = <4>;
  non-removable;

  brcmf: wifi@1 {
    reg = <1>;
    compatible = "brcm,bcm4329-fmac";
    laird,regdomain = "US";
  };
};

How will Laird handle the FRAG attack announced by Wi-Fi Alliance in 2021 May?

Please refer this blog as below. Laird are currently investigating these issues internally and investigating with the chipset vendors and our internal QA team to establish test scenarios to evaluate the impacted devices.

What are some disadvantages of using AP+STA?

The AP and STA are on the same channel potentially causing disconnections if the STA roams to a different AP. The Sterling-70 has the advantage of dual independent radios that can run on different Wi-Fi channels.

What is the MCS index for Wi-Fi?

MCS stands for Modulation Coding Scheme and is an industry metric index based on Wi-Fi connection parameters between a client and wireless access point. These parameters include modulation type, coding rate, spatial streams, channel width, and guard interval.

What versions of Android are supported by Laird Wi-Fi modules?

This can be found by reviewing the release notes for the specific product on GitHub.

 

I have a Ubuntu system that has automatic updates will this affect my Wi-Fi?

Yes as new kernels are updated in Ubuntu automatically it will break backports and will need to be reinstalled.

Can I use a Laird WiFi module on Ubuntu?

Laird modules can be used on a Ubuntu system with a kernel version that is supported by Laird backports.

To check, find the kernel version of the Ubuntu system and then check the release notes of the products to see if the latest backports supports that kernel.

Can I use VOUT_3P3 to power VDDIO?

No, if VBAT is 3.6V or greater, this power source should be used for VDDIO_RF, and USB2_AVDD33 if strapped for USB. Otherwise leave this pin disconnected.

Is there a way to extend the shelf life of Laird modules?? If the shelf life cannot be extended in any way, what are the consequences of using modules after shelf life?

The shelf life statements are essentially to prevent mishandling of the product and not storing it properly. If the modules are still sealed in the package, stored at the proper temperature and have not been exposed to moisture they should be fine. However, when working with modules beyond their shelf life you MUST bake the modules before populating the them to your board. Failure to bake the modules could result in the yield rate dropping down lower than expectation due to popcorn or de-lamination on the modules. It is recommended that you follow IPC/JEDEC J-STD-033 which is the general standard for the handling, packing, shipping and use of moisture/reflow sensitive surface mount devices.

Our main concern is around the castellation/pads which solder the module to the board. It is imperative those pads do not get tarnished, as this would cause soldering issues. Humidity can affect solderability as well, as if there is any excess moisture in the solder on the module, during reflow of the module to the board, steam balls can essentially explode the solder and sometimes result in an open circuit (or possibly a short circuit).

As long as all of the moisture handling and temperature guidelines are being followed you will likely have no issues. It is further recommended that when you do the build with modules that have exceeded their shelf life that you start with a handful to perform a test run and do a final test to make sure all is working as expected. As long as there are no issues with the initial test run we would expect that you will not experience any problems.

What is Laird Connectivity's product lifecycle EOL and PCN policy?

Laird Connectivity is committed to the long-term supply of all its standard embedded wireless modules and packaged products. Laird Connectivity’s products are specifically designed to meet the needs of the industrial and medical markets, which typically require 7 – 10 years product lifecycle.
