![User’s Guide Chapter 4 – Reference ManualIAPP RoamingAP1 AP2ClientRADIUS ServerFigure 27 – IAPP Roaming SchemeThe wireless client is switched from AP1 to AP2 when entering the coverage area of the new accesspoint (AP2). The roaming is performed without client re-authentication. The IAPP protocol ensures to inform the old AP1 of the new client association. The AP1 then stops the client RADIUS session, and the AP2 starts the client’s session with the RADIUS.IAPP roaming requires that all access points share the same SSID. Wireless Network Name (SSID) – is a unique name for your wireless network [1-32 symbols]. The default SSID is "P520" but you should change this to a personal wireless network name. The SSID is important for client stations when connecting to the access point. All client stations must have their client SSID settings configured and must use the same SSID. Band – click on the change policy… link and choose the policy of internal radio mode [Mixed/G-only/B-only].Changing the radio policy could result in a loss of your connection when you are using a wireless connection.Radio Channel – select the channel that the access point uses to transmit and receive information. Multiple frequency channels are used to avoid interference between nearby access points. If you wish to operate more than one access point in overlapping coverage areas, we recommend a distance of at least four channels between the chosen channels. For example, for three access points in closeproximity choose channels 1, 6 and 11. Click on the autochannel… link and a pop-up window with auto channel settings will appear. You can now select a list of preferred channels: Gemtek Systems Page 40](https://usermanual.wiki/GemTek-Technology/AP930301G.Manual/User-Guide-698765-Page-40.png)
![User’s Guide Chapter 4 – Reference ManualConfiguration | Wireless | Advanced Settings For normal operation the following default settings do not need to be modified. Changing the P-520r advanced settings requires expert knowledge of the 802.11 protocol and the radio functionality.The configuration menu Configuration | Wireless | Advanced Settings allows administrators to change low level radio parameters and antenna diversity settings: Figure 32 – Advanced Wireless Settings Operational Rate Set – this setting specifies the set of Supported and Basic data rates at which the station may transmit data. Each rate shall be within the range from 2 to 127, corresponding to data rates in increments of 500 kb/s from 1 Mb/s to 63.5 Mb/s, and shall be supported for receiving data.This value is reported in transmitted Beacon, Probe Request, Probe Response, Association Request,Association Response, Reassociation Request, and Reassociation Response frames, and is used to determine whether a BSS with which the station desires to synchronize is suitable. Operational rate set is defined as hexadecimal string where highest bit of each digit represents if Supported rate is the Basic rate (basic rate = supported rate | 0x80, where “|” means “bitwise or”operation).Beacon Period – this setting specifies the amount of time between beacons in milliseconds. A beacon is a packet broadcast by the access point to synchronize the wireless network.RTS Threshold – this setting specifies the maximum packet size beyond which the Wireless LANCard invokes its RTS/CTS mechanism. Packets that exceed the specified RTS threshold trigger the RTS/CTS mechanism. The NIC transmits packets smaller than this threshold without using RTS/CTS [[0-2347] default: 2347 (2347 means that RTS is disabled)].Fragmentation Threshold – the fragmentation threshold, specified in bytes, determines whetherpackets will be fragmented and at what size. On an 802.11 wireless LAN, packets exceeding thefragmentation threshold are fragmented, i.e., split into, smaller units suitable for the circuit size.Packets smaller than the specified fragmentation threshold value are not fragmented [[256-2346]default: 2346 (2346 means that fragmentation is disabled)].Enable TX and RX Diversity – choose this option to enable or disable the antenna diversity.
