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
– A high load on the network, perhaps from too many simultaneous access attempts

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.
from different nodes, can lead to lower data rates or communication problems.
