prefix. Therefore, an Access Point will filter out packets destined for these devices, and these devices will not be able to communi- cate through the Access Points with the wired network.

This is not an issue for Ethernet Access Points with revision 1.4 or greater of the flash code image installed. Proxim has modified the flash code for these Access Points to allow non-RangeLAN2 devices attached to an Ethernet Adapter to communicate with the wired network without having to disable the Fixed Node Filtering parameter. Note that in order for the Access Point to pass packets destined for these non-RangeLAN2 addresses to the wireless network, it must first learn of their existence. Therefore, each non-RangeLAN2 device must send a packet through the Access Point before the Access Point will begin to forward packets to it. This should not be pose a problem for the majority of networks.

However, if the network contains a Token Ring Access Point or the earlier mode of the RangeLAN2 Ethernet Access Point (model 7500), then the Fixed Node Filtering parameter must be disabled to allow packets destined for non-RangeLAN2 addresses to be transmitted to the wireless network. Note that transmitting packets destined for non-RangeLAN2 addresses may cause the overall wireless performance to decline.

If the Ethernet Adapter has Roaming Enabled, each Access Point to which the Ethernet Adapter may synchronize must be reconfigured so that Fixed Node Filtering is disabled. Therefore, if your Ethernet Adapter will be a stationary device, you should disable roaming in the Ethernet Adapter's Radio Configuration Menu so that Fixed Node Filtering will only need to be disabled on one Access Point on your network.

The procedure for disabling Fixed Node Filtering differs depend- ing on the model of the RangeLAN2 Access Point. Consult your Access Point manual for additional information.
