Transmit Errors
●
Transmission errors
Is incremented when a frame cannot be sent successfully despite hardware retries.
●
Dropped frames
Number of packages that were dropped either when the packet was not sent despite all
retries or packets that had not been sent when a node deregistered.
●
Acknowledged errors
Sum of all packets sent that were not confirmed by an acknowledge.
●
RTS errors
Sum of all sent RTS frames that were not acknowledged by a CTS.
●
Retry count
Sum of all frames sent successfully that required one or more retries.
●
One retry count
Sum of all frames sent successfully that required exactly one retry.
●
Multiple retry count
Sum of all frames sent successfully that required more than one retry.
Note
The percentages shown following the errors relate to the total number of received / sent
frames.
Overlap AP
Note
This menu command is available only in access point mode.
For optimum data throughput, it is important that the set wireless channel is not used by
other access points. In the 2.4 GHz band (802.11b or 802.11g), there is overlapping of the
wireless channels so that an access point occupies not only the set channel but also the two
or three adjacent channels. You should therefore make sure that there is adequate channel
spacing to neighboring access points.
The "Overlap AP" page shows all access points that are visible on the set or adjacent
channels (at 2.4 GHz). If entries exist here, the maximum data throughput of the access
point will be restricted.
●
Type
Shows the type of connection. The types AP (infrastructure mode) and AdHoc exist.
●
MAC address
The MAC address of the wireless devices.
●
Channel
The channel on which the found wireless device transmits.
●
Signal
Shows the signal strength with which the other wireless devices are received at the AP.
The stronger the signal, the greater the probability that they interfere with each other.
