How can I check if my SDIO Wi-Fi module is recognized by the system using command-line tools?
To check if your SDIO Wi-Fi module is recognized and available in a Linux system, you can use several command-line tools to probe the system and examine its output. Here are some commands that are commonly used for this purpose:
1) lsusb
and lspci
:
- If your SDIO Wi-Fi module is externally connected via USB or internally via PCI, use these commands to list the USB and PCI devices, respectively.
lsusb lspci
- Look for your Wi-Fi module in the output. External SDIO over USB adapters will appear in
lsusb
, while internal ones connected to the PCI bus will show up inlspci
.
2) dmesg
:
- This command displays kernel messages, which can be helpful to see if the module was detected during boot or when plugged in.
dmesg | grep -i sdio
- Replace
sdio
with a more specific keyword of your Wi-Fi module if needed.
3) ip link
or ifconfig
:
- These commands show network interfaces recognized by the system.
ip link
- or for older systems:
ifconfig -a
- Check if there's a new network interface that corresponds to the Wi-Fi module.
4) iwconfig
or iw
:
- These tools are specifically for wireless network interfaces.
iwconfig
- or using
iw
:iw dev
- These commands list wireless interfaces and can be used to identify if your SDIO Wi-Fi module is active as a network interface.
5) lshw
:
- This command provides detailed hardware information.
sudo lshw -C network
- It shows all network devices and their statuses, including any Wi-Fi modules.
6) lsmod
:
- Use this command to check if the driver modules required by the Wi-Fi card are loaded.
lsmod | grep -i wifi
- Replace
wifi
with the specific driver name if known.
7) Check System Logs:
- System logs can also provide information about hardware detection and driver loading.
cat /var/log/syslog | grep -i wifi
- Replace
wifi
with a more specific keyword of your WiFi module such aslrd
for some Laird specific drivers and firmware.
8) rfkill list
:
- This tool lists all wireless devices and shows if they are blocked or unblocked (enabled or disabled).
