ZyXEL v1.00_ZT.0_b1 release notes:

1. New Features and functionalities

Improved Rate Adaptation thresholds.

New ZyXEL GUI

2. Solved issues and limitations

SOLVED – Power save bit in control frames.

SOLVED – WPA key in WPA-PSK mode is now renewed after renaming of an

ESSID. There is no need to re-enter the pass phrase in ASCII for the new ESSID.

When in WPA pass phrase HEX mode rename of the ESSID is blocked. Only in

ASCII mode renaming of the ESSID is possible.

SOLVED – Adaptation did not start at highest rate.

SOLVED – ASCII characters 32-126 may be used in the pass phrase. Other special

characters should be avoided.

3. Reported issues and solutions

WEP Keys – WEP works with key index 1 only. Use WEP key index 1.

Redundant authentication packet sent by Centrino (while being associated) is

ignored by switch. As a result, Centrino may rarely disconnect and reconnect. This

may be observed under heavy traffic only.

Multiple RADIUS servers support: Use only one Radius server IP address for all

SSIDs. Same server should be used for all SSIDs

EAPOL_START is ignored by switch (to avoid DoS attacks)

Certain wireless clients do not connect to the system in pure 802.11g. Use mixed

mode in order to support these clients.

According to the standard ESSID may be up to 32 Alphanumeric characters only.

When working with SpectraLink handsets in WPA-PSK, it is recommended to

manually add the following lines to the XML configuration file:

In <channel> tag

Release notes

<ignore_rates_num>0</ignore_rates_num>

In <security> tag

<key_timeout>3000000</key_timeout>

<key_timeout_count>5</key_timeout_count>

Advisory: number of APs should not be divisible by DTIM value e.g eight APs and

DTIM=4 is not a good selection, chose DTIM=3 in such a case.

4. Installation and upgrade notes
