13.0 Troubleshooting
13.1 Troubleshooting steps
13.1.1 PC cannot connect to the NetWave device
The configuration web page for the NetWave device would not be able to show up if the NetWave
device and your computer are not connected. If the PC and the NetWave device are joined
to the network by LAN cables, they would not be able to connect if any of the network cable
connections are loose. A possible indicator is that there is no light at the LAN port of the PC. In
Windows, if you click the network icon and click to “View network connections”, the LAN port
shows “Disconnected”. Please ensure that all the connections are tight. Sometimes, disconnecting
and reconnecting the LAN cable solves connection problems if DHCP is used, because the DHCP
server and DNS server are reset.
(Also, dis-associating and re-associating to the wireless network has a similar benefit as
unplugging and re-inserting the LAN cable.)
The NetWave device, the computer, and the gateway must have IP addresses on the same
network. For example, if you use a subnet mask of 255.255.255.0 and the gateway IP address is
192.168.3.1, all the IP addresses must be unique and be of the form 192.168.3.X. Check whether
the NetWave device and your computer are connected on the same network by running the ping
command to ping the IP address of the NetWave device.
Alternatively, type the following in the NetWave device's Linux terminal:
• ping 192.168.3.77 (if your computer's IP address is 192.168.3.77 for example.)
They should be able to give the ping responses.
An IP address conflict would cause unstable pings.
Switch to another address and ping the conflicting address to check.
If using a Windows computer, you should run the command arp -d * if the network configuration
has changed. This is to delete the address resolution protocol (ARP) table in Windows as it may
not update fast enough.
If the ping still cannot get responses, try disabling the firewall on your Windows computer. The
Windows Firewall on your computer may prevent it from sending back a ping response. Disabling the
firewall may be a security risk, so you should take the precaution of disconnecting the Internet first.
13.1.2 PC Ethernet and Wifi adapters
If your PC has both Ethernet and Wifi adapters, they must not have the same subnet. Otherwise,
packets from the PC may not be directed to the correct network.
13.2 Resetting to factory default
To reset the router to the factory default settings, while the power is on, hold down the reset
button for 8 seconds and then release
