• Make sure you have a compatible mobile broadband device installed or connected. See
www.zyxel.com for details.
• Make sure you have the cellular interface enabled.
• Make sure the cellular interface has the correct user name, password, and PIN code configured with
the correct casing.
• If the Zyxel Device has multiple WAN interfaces, make sure their IP addresses are on different subnets.
Hackers have accessed my WEP-encrypted wireless LAN.
WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available software.
It is strongly recommended that you use a more effective security mechanism. Use the strongest security
mechanism that all the wireless devices in your network support. WPA2 or WPA2-PSK is recommended.
The wireless security is not following the re-authentication timer setting I specified.
If a RADIUS server authenticates wireless stations, the re-authentication timer on the RADIUS server has
priority. Change the RADIUS server's configuration if you need to use a different re-authentication timer
setting.
I cannot configure a particular VLAN interface on top of an Ethernet interface even though I
have it configured it on top of another Ethernet interface.
Each VLAN interface is created on top of only one Ethernet interface.
The Zyxel Device is not applying an interface's configured ingress bandwidth limit.
At the time of writing, the Zyxel Device does not support ingress bandwidth management.
The Zyxel Device is not applying my application patrol bandwidth management settings.
Bandwidth management in policy routes has priority over application patrol bandwidth management.
The Zyxel Device's performance slowed down after I configured many new application patrol
entries.
