Switching the WLAN Channel
An undefined malfunction occurs.
Performing a Ping Test
A ping to any web URL appears to be faster without the
power save feature (Eco mode).
Possible Cause
Radio traffic is subjected to interference by strong irradi-
ation.
Remedy
Switch the WLAN channel setting on the access point.
Find a better location for the WLAN devices to avoid
potential interference from baby monitors, video
bridges, microwaves, cordless DECT telephones or
Bluetooth devices.
Possible Cause
The new power save feature provides for efficient energy
management: When data traffic between the access
point and the stick is idle, energy consumption is re-
duced. The stick heats up less. The Eco mode works not
only with a FRITZ!Box WLAN, but also with other access
points as remote sites.
Remedy
The amount of data transmitted for a ping is not suffi-
cient to wake the FRITZ!WLAN USB Stick up from Eco
mode. In a typical online gaming scenario, enough data
packets are exchanged over the WLAN route to normalize
the ping values.
