Wireless Troubleshooting
Is it a hardware problem ?
If following symptoms happen on the access point
- None of
the LEDs turn on when I plug in the power
adapter
Make sure you are using the supplied power adapter and that
it is plugged in to an appropriate power source. Check that the power source is
turned on. If the problem persists, you may have a hardware problem. In this
case, you should contact your local vendor.
- The Access
Point reboots automatically sometimes
The supplied power to Access Point is too low. Check that
the Access Point is receiving enough power. ¡@
How can I check to be sure if I am interfered or not ?
There may not be an easy or quick answer to this. One thing
to notice first is whether the problems are continuous or intermittent.
Interference usually occurs intermittently, or else it would have likely been
noticed when the link was first commissioned.
If I've confirmed it is an interference problem. What
should I do?
Change the location and choose other radio channel to see
whether the impact of the interference decreases and the link quality improves.
What should I do if I have low signal or high noise ?
To improve the signal, check or get the antennas with
reverse SMA type connectors. For noise problems, please shield or remove the
interference. If the situation doesn't improve, please change radio channels.
Unable to associate to the access point
- Verify that
the PC card or PCI adapter is installed correctly.
- Is the
signal strength and link quality good ? Move
closer to the access point to see if it helps ?
If not, you may have radio problems. Make sure you are in the wireless
coverage of your access point.
- Temporarily
disable the WLAN MAC Filter function on the access point. If this solves
the problem, check to make sure the MAC address of the wireless client is
not contained in the list of denied MAC addressed.
- Temporarily
disable any security feature on both the access point and the client. If
this solves the problem, check to make sure that the Wired Equivalent
Privacy (WEP) key you use to transmit data is set up exactly the same on
your AP and on any wireless devices with which it associates.
- Make sure the
configuration on access point and wireless consistent. Verify that the
configuration for the SSID on PC matches the access point's ESSID.
Unable to authenticate to the access point
If your client adapter is unable to authenticate to an
access point, check the security settings of your client adapter and the access
point. These include the following areas:
Authentication with shared key (WEP):
If you use WEP shared key to authenticate the wireless
clients, you should check whether following configuration parameters on both AP
and wireless clients match:
- WEP key
values, WEP key sizes, WEP activation, and WEP transmit key parameters
¡@
Unable to transmit traffic
- Verify
that the client has passed association and authentication.
- Make sure
the client is configured with exact IP setting or get a valid IP address
from DHCP server. You can go to a DOS prompt and type: ipconfig
and press Enter to verify this.
- Ping the
gateway in your network. A response other than Request timed out indicates
a successful ping.
- Enable
packet trace function on the access point Verify that the Wired Equivalent
Privacy (WEP) key on the client is set up exactly the same on your AP.
What should I get back to my technical support for analysis ?
Following information are helpful to your technical support
to troubleshoot your problem, please get back the answer and associated files
to your support:
- Is this a
new or existing installation ?
- Did it
work before ?
- Have there
been any recent changes that might affect the LAN, the client workstation
or the radio environment ?
- What is
the firmware version you are using now ? Do you
have uploaded firmware recently ?
- Is
addresses, networking information and ROMFILE available
? If yes, please send it (include your password) to your support.
