Resolved Caveats
Resolved Caveats
This section describes resolved caveats for client adapter firmware release 4.25.30.
Roaming Issues with Client Adapters
When a client is associated to an access point and then moves away from the access point and closer to
another access point, the client maintains association with the first access point even if the signal
strength is very low and the signal quality is poor. If you remove and reinsert the card, the client
associates to the second access point, and ACU shows a high signal strength and excellent signal quality
(CSCdv68043). This caveat is resolved in firmware release 4.25.30 and ACU release 5.02.005 with the
addition of the Periodically Scan For A Better Access Point parameter. When this feature is enabled on
the ACU RF Network screen (which is the default value), the client will look for a better access point if
its signal strength becomes low and will switch associations if it finds one.

Poor Throughput with 350 Series PC Card in IBM Laptop
If you install a 350 series PC card in an IBM 600E laptop that is running Windows 98 or 2000, the card
experiences very poor throughout (CSCdu17477 and CSCdw71765). These caveats are resolved in
firmware release 4.25.30.

Wideband Japan Channel Set Displays Incorrect Power Levels
The 4800 series client adapters do not display the correct available power levels when programmed to
the wideband Japan channel set (CSCdv57626). This caveat has been closed because wideband Japan is
not a valid factory configuration on the 4800A.
