Troubleshooting
(Continued)
There is Radio Interference
You may be able to eliminate RF interference by trying the following:
Find the “channel” used by the source of the interference and coordinate
your network and the interference source to be on channels that are at
least 20MHz, but preferably 30MHz, apart. Channels 1,6, and 11 are
non-overlapping.
Move the
DPG-2000W
to a location where the interference is minimized;
in general, increase the distance between the wireless computers and
the device causing radio interference.
Avoid using devices operating in the 2.4Ghz range in the same vicinity
of the
DPG-2000W
.
Keep the computer with the
DPG-2000W
away from microwave ovens
and large metal objects.
2) If the current presenter failed to resume presentation by clicking
“Establish a Session”, another presenter should try to “Establish a
Session.” If this new presenter can successfully start a presentation,
the problem was localized on the previous presenter’s computer and/
or its wireless card. Address that problem after the meeting.
3) If a second presenter also fails to “Establish a Session” to the
DPG-2000W
, a persistent abnormal condition has to be identified. Follow
other trouble-shooting tips in this section to identify the persistent
abnormal condition.
4) Power cycle the
DPG-2000W
.
