Encapsulation

 shows one of two different network packet forming modes

 

None or Encapsulated 

This setting takes the entire Ethernet frame, including the Ethernet

Header, and puts it into an 802.11 frame. This setting is here for compatibility with some older

802.11 implementations and should not normally be used.

 

RFC1042 

where the DIX Ethernet frames are converted using SNAP header based on

RFC1042. This mode will also convert any RFC1042 SNAP header frames to DIX Ethernet

frames before transmission to the Ethernet interface.

 

802.1h 

where the DIX Ethernet frames are tunneled using a full selective translation table. This

mode does not convert RFC1042 SNAP header frames to DIX Ethernet before transmission to

the Ethernet interface

It is required to select encapsulation mode corresponding to the one your access point or other

workstations use. If the encapsulation mode is incorrect, the PC will join to access point or will

be seen by other workstations, but network operation will not work.

Channel

 

– shows radio channel number used for networking. Only Access Points and Ad Hoc nodes

can create a BSS therefore this parameters is not active if Mode is Infrastructure. Infrastructure Client

nodes will always go the same channel as their AP. Please see the table for the requirements of

different countries and the channel frequency.

TX Rate: 

The transmission rate at which the data packets are transmitted by the client or AP. You can

set this to 

Auto select I or 2Mbps, Fixed 1 Mbps, Fixed 2 Mbps, Fixed 5.5

 

Mbps, Fixed 11 or  Full Auto

(I to 11 Mbps).

Important:

 You must know the T

Rate that your AP can support.  Failure to which may

cause the undesired 

results.
