Statement of Conditions The information contained in this manual is subject to change without notice. Breeze Wireless Communications shall not be liable for errors contained herein or for incidental or consequential damages in connection with the furnishing, performance, or use of this manual or equipment supplied with it.

[. . . ] This parameter is a threshold in RSSI units that determines the sensitivity of the Carrier Sense mechanism. Signals with a lower RSSI are considered "noise", and the unit disregards them. · Carrier Sense Difference Level ­ Carrier Sense Difference Level refers to a sudden rise of the signal level. This parameter is the minimum rise in RSSI units to be considered a Carrier Sense positive result, in which case the unit will not attempt to transmit. Rate The Rate menu contains the following parameters: · Multi-Rate Support ­ When this parameter is enabled, the unit will automatically switch to the best transmission rate at any given time. · Multi-Rate Decision Window Size ­ It is not recommended to change the value of this parameter. · Rate Counters ­ The number of frames transmitted in each data-rate since the last time the unit was reset. In APs, the counters for all associated stations are displayed, indicated by their MAC address. In stations, only the stations' rate counters are displayed with no indication of address. The rate counters show the rate the packet was transmitted for the first time, not including retransmissions. The Ret counter shows the number of frames that had to be retransmitted, and does not count the number of retransmissions that actually accrued. Checking rate counters is the best way to determine which data rate is optimal for the unit. It is recommended to restrict the Maximum Data Rate (refer to section 4. 4. 3) for each unit according to these counters. 4. 5. 6. Maintenance The Maintenance menu contains the following parameters: · Display Alarm Log ­ The last four error messages that the unit displayed since the last Factory Defaults reset. The Alarm log stores events and four levels of error notifications: MSG (Message), WRN BreezeNET PRO. 11 Series 4-14 Installation Guide Device Setup and Management (Warning), ERR (Error), and FTL (Fatal). You can control message severity as follows: in the main menu, press Y-Testing, press 2-System Info and System Parameters, and press 4-Events Storage. Use the 1Event Storage Policy runtime value option to set the policy until the next reset. Use the 2-Event Storage Policy Nv ram value option to set the policy for the Alarm Log stored in the Nv ram. · Wait for Association Address (SA only) ­ The Association Address is the MAC address of the NIC (Network Interface Card) card that the station is connected to through the Ethernet UTP cable (usually the Ethernet card of the PC). The station uses the Association Address as it's identification in the Wireless Cell (WLAN Address). When a station is first connected to an Ethernet port, it waits for the Association Address update over the Ethernet. You can have the device use its own MAC address (Use Mine) for testing purposes, in which case there will not be a proper network connection. [. . . ] · Verify antenna polarization.

Corrective Action · Verify antenna alignment. · Check length of cable between antenna and unit (an overly long extension cable may adversely affect performance). Unit associates with the wrong Access Point. In a multicell structure with overlapping cells, the units may not associate with the closest Access Point. For a unit to associate with a specific Access Point, assign a unique ESS ID to the Access Point and to all the units you want to include in that wireless network. Each AP must have a unique hopping sequence regardless of ESS ID. Reduced performance in a multi- The APs in the same coverage AP configuration. "DE" unit.
