Important Notes
Throughput Option for 802.11g Radio Blocks Association by 802.11b Clients
When you configure the 802.11g access point radio for best throughput, the access point sets all data
rates to basic (required). This setting blocks association from 802.11b client devices. The best
throughput option appears on the web-browser interface Express Setup and Radio Settings pages and
in the speed CLI configuration interface command.

Transmit Power Set to Maximum When You Install 802.11g Radio
When you replace the 802.11b radio in a 1200 series access point with an 802.11g radio, the 802.11g
radio is set to the maximum transmit power allowed in your regulatory domain regardless of the power
setting configured on the 802.11b radio. After you install the 802.11g radio and the access point reboots,
configure the 802.11g radio to the preferred transmit power.

System Software Upgrade Sometimes Fails Due to Insufficient Memory
When you use the web-browser interface to upgrade access point system software, this error might
appear:
appear:
ERROR: Not enough system memory for HTTP upgrade.
This error indicates that your access point or bridge does not have enough free processor memory to
transfer the entire system image over HTTP. The memory shortage might be caused by memory
fragmentation, which can happen over long-term operation of the unit, or by features that require
significant memory, such as WDS. To complete the upgrade using the web-browser interface, free the
required memory by disabling the radio interfaces and high memory-usage features such as WDS, and
reboot the access point. After the access point reboots, try the upgrade again.

If you use the CLI to disable access point features, remember to save the configuration to Flash
before rebooting.

Use Auto for Ethernet Duplex and Speed Settings
Cisco recommends that you use auto, the default setting, for both the speed and duplex settings on the
access point Ethernet port. When your access point receives inline power from a switch, any change in
the speed or duplex settings that resets the Ethernet link reboots the access point. If the switch port to
which the access point is connected is not set to auto, you can change the access point port to half or
full to correct a duplex mismatch and the Ethernet link is not reset. However, if you change from half or
full back to auto, the link is reset and, if your access point receives inline power from a switch, the access
point reboots.

Note
The speed and duplex settings on the access point Ethernet port must match the Ethernet settings
on the port to which the access point is connected. If you change the settings on the port to which
the access point is connected, change the settings on the access point Ethernet port to match.
