Hi!
I’m experiencing difficulties connecting to Wi-Fi networks, particularly “CIC” (an open network on DFS channels) and “GETALOOKOUT” (secured with WPA2), on the Seeed Studio NVIDIA Jetson Orin NX 16GB Edge AI Device - reComputer J4012. The device seems to recognize available networks but fails to connect. Below is a detailed list of troubleshooting steps taken and their outcomes.
Device and Setup
- Device: Seeed Studio NVIDIA Jetson Orin NX 16GB Edge AI Device - reComputer J4012
- OS: JetPack 5.1
-
Wi-Fi Networks:
- “CIC” (Open network, channels 56 and 60, 5 GHz, DFS channels)
- “GETALOOKOUT” (WPA2, channels 7 and 40, 2.4 GHz and 5 GHz)
Troubleshooting Steps and Results
-
Basic Connection Attempts via
nmcli:
-
Command:
sudo nmcli device wifi connect "CIC" -
Result: Connection timed out with error
(11) 802.1X supplicant took too long to authenticate, despite “CIC” being an open network. -
Command:
sudo nmcli device wifi connect "GETALOOKOUT" password "lookout2133" -
Result: Failed with error
(7) Secrets were required, but not provided.
-
Manual Wi-Fi Connection with
iwconfiganddhclient:
-
Commands:
- Set ESSID and frequency:
sudo iwconfig wlan0 essid "CIC" - Set specific channel and frequency for DFS:
sudo iwconfig wlan0 channel 60andsudo iwconfig wlan0 freq 5.3G - Attempt IP assignment:
sudo dhclient wlan0
- Set ESSID and frequency:
-
Result: No connection established;
dhclientstalled without assigning an IP.
- Adjusting Wi-Fi Power and Region Settings:
-
Commands:
- Disable power management:
sudo iwconfig wlan0 power off(returned “Operation not permitted”) - Set regulatory domain:
sudo iw reg set US
- Disable power management:
- Result: No improvement in connection stability or signal strength.
- Network Manager and System Restarts:
-
Commands:
- Restart Network Manager:
sudo systemctl restart NetworkManager - Toggle the Wi-Fi interface:
sudo ifconfig wlan0 downandsudo ifconfig wlan0 up
- Restart Network Manager:
- Result: Still unable to connect to “CIC” or “GETALOOKOUT”.
- Channel and Signal Analysis:
-
Command:
sudo iwlist wlan0 scan | grep -E 'SSID|Signal|Channel' - Result: Confirmed weak signal levels (around 10-20 out of 100) even when close to access points, with both “CIC” and “GETALOOKOUT” showing low quality.
- Checking Device and DFS Restrictions:
-
Command:
iw list | grep -A 10 Frequencies - Result: Verified that channels 56 and 60 are DFS channels with radar detection. Possible DFS restrictions may be impacting connection attempts on “CIC”.
Summary of Issues
- Primary Issue: Unable to establish a stable Wi-Fi connection on open and secured networks, with timeouts during connection attempts.
- Possible Causes Considered: Weak signal strength (despit router being nearby), DFS restrictions on 5 GHz channels, driver compatibility for the Realtek Wi-Fi adapter, and potential power management issues.
