10. Troubleshooting
⚫ SSH login fails
➢ Make sure that the PC and Raspberry Pi are correctly connected using an Ethernet
cable.
➢ Connect to Raspberry Pi as explained at 8.1 and check the IP address of the Ethernet
I/F(eth0) using the ifconfig command.
⚫ Even if a wireless driver is loaded, the wireless interface (wlan0) is not generated.
➢ Check the DIPSW setting of SX-NEWAH-EVK (7.1.1 DIP Switch Setting).
➢ Check the connection between Raspberry Pi and SX-NEWAH-EVK.
➢ Restart SX-NEWAH-EVK and try again.
⚫ Wireless connection between AP and STA is not established.
➢
Check that the settings described in the configuration files are correct for both AP’
and STA’ ( ap_halow_*.conf or sta_halow_*.conf).

When WPA2-PSK, WPA3-SAE/OWE is used:
Check that the settings (e.g. wpa_passphrase, IEEE 802.11w, etc.) are identical
between the AP’s and STA’s configuration files (ap_halow_*.conf or
sta_halow_*.conf).
⚫ iperf throughput is low
➢
The reception strength may be too strong as the units are too close. Keep more
distance between the units or change the Tx power for both AP/STA units using the
txpwr command.
➢
Check the connection between antenna and the antenna cable.
