The original Wireless USB 2.0 Sender unit and Wireless USB
2.0 Receiver unit placement is too far apart. Move the units
to physically closer positions that have fewer obstacles in the
way (walls, ceilings, etc).
And/or, there is excessive Radio Interference on the 802.11g
Radio Channel.
Using standard Wireless Networking software, confi rm if there
are any other 802.11g radio networks operating on or near the
same channel as the Wireless USB 2.0 Extender. (Note you
can determine the current Wireless USB 2.0 Extender Radio
Channel using the procedure on Page 9.)
Confi gure all confl icting 802.11g products so that they use
evenly separated Radio Channels. Optimal separation is
fi ve channels, so channels 1, 6, and 11 will provide the least
interference between themselves.
If the Wireless USB 2.0 Extender cannot establish
wireless communications at short range:
Confi rm that the Radio Antennas are properly secured to the
antenna connectors of the Wireless USB 2.0 Extender.
Confi rm the Radio Channels of the Wireless USB 2.0 Sender
unit and the Wireless USB 2.0 Receiver unit as described on
Page 9.
If the Wireless USB 2.0 Sender unit and the Wireless USB
2.0 Receiver unit are not confi gured with the same Radio
Channels, then set both units to the same channel as
described on Page 10.
If both units are already confi gured to the same Radio
Channel, then attempt the Pairing Procedure described on
Page 12.
