Setting Up MUs
Legacy MUs
For a discussion of how to initially test the access point to ensure it can interoperate with the MUs
intended for its operational environment, see
"Testing Connectivity" on page
802.11n MUs
Third-party 802.11n clients can connect to the Access Point using default settings with no additional
user intervention. However, there could be instances where the specific (high-performance) 802.11n
settings cannot be sustained due to adverse radio traffic conditions within the network. When this
occurs, Extreme Networks recommends changing the Windows XP settings so the adapter can use
settings defined for legacy (802.11a/bg) adapter operation. Once network conditions improve, use
Windows XP to re-enable the adapter for 802.11n support.
To change the Access Point's settings to support legacy 802.11a/bg operation (using Windows XP):
1 Select My Network Places.
2 Right-click and select Properties. The Network Connections screen displays.
3 Select (right-click on) the adapter supporting 802.11n operation with the Access Point and select
Properties.
4 Click on the Configure button.
5 The Network Connection screen displays supporting the 802.11n adapter.
6 Select the Advanced tab.
7 Select 802.11n Network from the Property field and select either Enable or Disable from the Value
drop-down menu.
8 Select Disable when the 802.11n rate settings and performance values defined on the
Access Point cannot be sustained (due to network congestion or interference). Once network
conditions improve to the point where 802.11n traffic can be sustained, enable the 802.11n Network
parameter once again.
