Appendix A: Troubleshooting
Symptom Possible Causes Things to Do
Inability to access the router • Incorrect or incompatible
wireless network configuration.
For example, shared key
authentication is configured on
the wireless AP/Router and the
wireless client is attempting
open system authentication
• Inadvertent media access
control (MAC) address filtering
• The wireless network name
is not visible
• Verify that the wireless
network configurations
between the wireless client
and wireless AP/Router are
compatible. Make sure that the
client system’s network card is
set to receive IP automatically.
•Use “Ipconfig” utility to verify
that the client is getting an IP
address from the router:
1. Click Start > Programs and
select Command Prompt.
2. Type ipconfig /all at the
command prompt.
3. With default settings on the
router, client should get an IP
address in the range of
192.168.1.XX with a default
gateway IP of 192.168.1.254.
• The wireless AP/Router and
wireless network adapter are
not using the same 802.11
standard (for example, you are
using an 802.11a network
adapter and a 802.11g
wireless AP/Router) • Use the same 802.11
standard for wireless
AP/Router and wireless
network adapter.
• Radio frequency (RF)
interference from nearby
devices such as cordless
phones and Bluetooth devices • Remove the device causing
the interference.
• Wireless client is at the
periphery of the RF range of
the wireless AP/Router • Move the wireless client
closer or re-locate the wireless
AP/Router..
• Improperly functioning or
outdated wireless network
adapter driver • Obtain and install the most
recent version of the wireless
network adapter driver.
• Cable failure (when wired to
the router) • Check the “Link” LED next to
the port on the router. Make
sure that Ethernet cables are
connected properly.
