Troubleshooting

3.1.1

The PC Cannot Connect to the WBSIac AP

The configuration web page for the WBSIac AP would not be able to show up if the WBSIac AP and your
computer are not connected.
If the PC and the WBSIac AP 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 View network connections,
the LAN port shows Disconnected. 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.
The WBSIac AP, 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 WBSIac AP and your computer are connected on the same network by running the
ping command to ping the IP address of the WBSIac AP. Alternatively, type the following in the AP's
Linux terminal:
ping 192.168.3.77
if your computer's IP address is 192.168.3.77 for example.
There should be 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.

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.
