It Isn’t Working! Why not?
Rabbit-based Ethernet products should work with any access points that perform wireless bridging. There
is nothing special to do in order to get Rabbit Ethernet support working. It should also work with the
“wireless bridging” products, with the exception of the Linksys WET11 mentioned earlier.

If you have a Linksys WET11 device and a Rabbit device with a Realtek Ethernet chipset, you may have
problems with the WET11 constantly rebooting and locking up. It can be made to work by connecting with
a 50 foot or longer Ethernet cable or by adding 15 ohm resistors inline on the TX+ and TX- lines of the
Ethernet cable on the WET11 side of the cable. Because of this problem, we do not recommend the
Linksys WET11.

If you cannot ping the local access point from the Rabbit, then check that you are using a crossover cable
from the Rabbit to the access point. If your access point has a crossover switch, then set it to the “X” posi-
tion and use a straight-through cable. Try hooking a PC directly to the access point (reconfigure the net-
work interface on the PC to be on the same subnet as the access point, if necessary).

work interface on the PC to be on the same subnet as the access point, if necessary).
If the wireless connection is not working, there are several possible sources of errors. Make sure that all
devices are on the same subnet (with the same netmask). Check the SSID and channel values on the access
points. Make sure that the encryption keys match—if you entered it via a passphrase, check that the pass-
phrases and the keys are the same on each access point. You could be outside the range of the access
points, or interference could be causing problems. The more walls between the access points, the smaller
the range. Try testing the connection with the access points close to each other. If it still is not working, try
connecting a PC with the access points and verify that that works.

Also note that your two wireless access points will probably need to be the same model. It is also possible
that the model of access point you have does not support wireless bridging. Query the product’s technical
support if you are unsure.

If, after all of this, your wireless connection with your Rabbit is still not working, try hooking the Rabbit
up through a wired connection to make sure that there is not a more general problem. If you are all out of
ideas, and a wireless connection between PCs works, then contact Rabbit Semiconductor technical support
for further assistance.
