Troubleshooting
| Problem / Symptom
|
Possible Solution
|
| My
TM1100PC adapters can't associate with my Access
Point. |
- Verify that the
Service Set ID (SSID) on the Access Point and the adapter are
identical. Remember that the SSID is case
sensitive.
- Verify that the data
rates on the Access Point and adapter are set correctly. The
Access Point sets the data rates for the network. 11, 5.5, 2, and
1 Mbps data rates are available. Each rate can be set to basic,
yes, or no. Basic means that a card has to support that
rate in order to associate. Yes means that the rate is
optional. No means that the rate will not be used. If
you have more than one rate set to basic then the adapters data
rate has to be set to auto. My Windows 95 computer can not
access the Internet.
- If WEP is enabled
verify that the WEP Key on the Access Point and the adapter are
identical.
|
| I
can't get adapters to associate with my Access Point when using
WEP. |
- If you have set WEP
to be optional on the Access Point and your adapter is using WEP
then you need to select the Allow Association to Mix Cells
box on the RF Network tab in WinDGS.
|
| My new
Windows 95 computer can not access the Internet. |
|
| When I shutdown or suspend my computer, roam to another part of the building and restart I lose my connection |
|
| Docking and Undocking Issues |
- When using a dock with an internal NIC, you must remove your wireless LAN card before docking
- If your dock has an internal NIC and your are using TCP/IP, you should configure the wireless LAN card for DHCP and the internal NIC with a static IP address.
- If you lose you connection when docking/undocking, you may need to release and renew your IP address (see the 1st bullet above).

Indicator
LEDs
The PC Card has two
indicator LEDs (green and amber) on the face of the card.
The green indicator is
the Link Integrity/Power LED. It lights when the card is receiving
power and flashes slowly when the PC Card is linked with the
network.
The amber indicator is
the Link Activity LED. It flashes when the PC Card is receiving or
transmitting data or in a pattern to indicate an error
condition.
See Tables 3.1 and 3.2
for an explanation of the LED Messages.
