Problems with WLAN
The following lists the possible causes for problems with Wireless LAN:
Cannot connect with WLAN
Check that you have enabled the WLAN.
Check that the other WLAN partner is active.
Check the WLAN connection settings
Observe the corresponding notes on WLAN configuration and operation in the Online
Help of the WLAN adapter.
Data transmission speed is too low
Please note that the data rate stipulated and visible under Windows is only a theoretical
value / corresponds to the gross value. Determined by the transmission procedure, the
actual applicable data rate for the data transmission is usually around 50% of the gross
value.
The maximum data transmission speed depends on many factors.
Start by verifying that the transmission mode of all network components is set up in
accordance with the IEEE 802.11 a/b/g/n or ac standard.
The spatial arrangement of the network components can also negatively influence the
transmission.
The distances between the components should be as short as possible.
Masonry or reinforced concrete walls have a negative effect on the transmission
performance and can, under some circumstances, prevent a connection from being
established. For the best performance, a line-of-sight connection of the network
components is preferred.
A high load on the network, perhaps from too many simultaneous access attempts
from different nodes, can lead to lower data rates or communication problems.
