Resetting The Zyxel Device - ZyXEL Communications NWA Seres User Manual

Any certificate that you want to import has to be in one of these file formats:
3
• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, uppercase
letters and numerals to convert a binary X.509 certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital signatures)
that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The private key is not
included. The Zyxel Device currently allows the importation of a PKS#7 file that contains a single
certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase letters,
uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable form.
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The private key
in a PKCS #12 file is within a password-encrypted envelope. The file's password is not connected to
your certificate's public or private passwords. Exporting a PKCS #12 file creates this and you must
provide it to decrypt the contents when you import the file into the Zyxel Device.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy for this
to occur since many programs use text files by default.
Wireless clients are not being load balanced among my Zyxel Devices.
• Make sure that all the Zyxel Devices used by the wireless clients in question share the same SSID,
security, and radio settings.
• Make sure that all the Zyxel Devices are in the same broadcast domain.
• Make sure that the wireless clients are in range of the other Zyxel Devices; if they are only in range of a
single Zyxel Device, then load balancing may not be as effective.
In the Monitor > Wireless > AP Information > Radio List screen, there is no load balancing indicator
associated with any Zyxel Devices assigned to the load balancing task.
• Check that the AP profile which contains the load balancing settings is correctly assigned to the Zyxel
Devices in question.
• The load balancing task may have been terminated because further load balancing on the Zyxel
Devices in question is no longer required.

29.6 Resetting the Zyxel Device

If you cannot access the Zyxel Device by any method, try restarting it by turning the power off and then
on again. If you still cannot access the Zyxel Device by any method or you forget the administrator
password(s), you can reset the Zyxel Device to its factory-default settings. Any configuration files or shell
scripts that you saved on the Zyxel Device should still be available afterwards.
Use the following procedure to reset the Zyxel Device to its factory-default settings. This overwrites the
settings in the startup-config.conf file with the settings in the system-default.conf file.
