Manual: Interface/Wireless - Mikro. Tik Wiki. Overview. Standards: Package: wireless. Router. OS wireless comply with IEEE 8. WPA, WEP, AES encryption, Wireless Distribution System (WDS), Dynamic Frequency selection (DFS), Virtual Access Point, Nstreme and NV2 proprietary protocols and many more. Wireless features compatibility table for different wireless protocols. Client/station also can operate in different modes, complete list of supported modes can be found here. Note that no authentication is done for these clients (WEP Shared keys are not compared to anything) - they are just accepted at once (if access list allows that)ampdu- priorities (list of integer . Using AMPDUs will increase throughput, but may increase latency therefore may not be desirable for real- time traffic (voice, video). Due to this, by default AMPDUs are enabled only for best- effort traffic. AMSDU aggregation may significantly increase throughput especially for small frames, but may increase latency in case of packet loss due to retransmission of aggregated frame. Sending and receiving AMSDUs will also increase CPU usage. This value is announced by AP, and can be matched in connect- list by area- prefix. Read more > > burst- time (integer . Note that no other wireless cards in that network will be able to transmit data during burst- time microseconds. This setting is available only for AR5. AR5. 00. 1X, and AR5. X+ chipset based cards. Ceee . Ce, e. C etc) allows additional 2. MHz extension channels and if it should be located below or above the control (main) channel. Extension channel allows 8. MHz (8. 02. 1. 1ac up to 8. What Is Preamble Mode Wifi CameraMHz) of spectrum in total thus increasing max throughput. Default: )Short description of the interfacecompression (yes . Wireless interface must have support for hardware compression. Connections with devices that do not use compression will still work. Also specifies default value of scan- list. For station mode, this is the value of connect for APs that do not match any entry in the connect- listdefault- client- tx- limit (integer . Why is a long preamble the default and what does auto do? I read up on what exactly the preamble in (the physical layer of) wifi is. So long as you are running G mode only. It can be enabled in the 5 GHz mode. Mixed Mode: In this 802.11n mode, packets are transmitted with a preamble compatible with the legacy 802.11a/g. The rest of the packet has a new MIMO training sequence format. Greenfield Mode: In the Greenfield mode. In India, the Supreme Court frequently rules. In 'wds- slave' mode this setting has no effect. Select channel with the lowest number of detected networks and use it if no radar is detected on it for 6. Otherwise, select different channel. This setting may be required by the country regulations. This property has effect only in AP mode. At this point 3 * (hw- retries + 1) frame transmits on the lowest data rate had failed. If no frame can be transmitted successfully during diconnect- timeout, connection is closed, and this event is logged as . Successful frame transmission resets this timer. Value 'dynamic' causes AP to detect and use smallest timeout that works with all connected clients. By default, when value of this property is 0, frames are discarded only after connection is closed. In Winbox, scanlist frequencies are in bold, any other frequency means the clients will need scan- list configured. Allow all channels supported by the card. This page contains more robust explanations of Advanced Wireless Settings than the built in help provides. Depending on the wireless mode you have selected. This mode allows you to test wireless channels outside the default scan- list and/or regulatory domain. This mode should only be used in controlled environments, or if you have a special permission to use it in your region. Before v. 4. 3 this was called Custom Frequency Upgrade, or Superchannel. Since Router. OS v. So if your card works at 4. MHz but Router. OS shows 5. MHz, set offset to 1. MHz and it will be displayed correctly. The value is in MHz and can be positive or negative. Setting it to yes can remove this network from the list of wireless networks that are shown by some client software. Changing this setting does not improve security of the wireless network, because SSID is included in other frames sent by the AP. Refer to 8. 02. 1. MCS specification. Refer to 8. 02. 1. MCS specification. MSDU in 8. 02. 1. Note that transmission of fragmented packet is less efficient than transmitting unfragmented packet because of protocol overhead and increased resource usage at both - transmitting and receiving party. Three sequential failures on lowest supported rate suspend transmission to this destination for the duration of on- fail- retry- time. After that, frame is sent again. The frame is being retransmitted until transmission success, or until client is disconnected after disconnect- timeout. Frame can be discarded during this time if frame- lifetime is exceeded. Virtual AP interface will only work if master interface is in ap- bridge, bridge or wds- slave mode. This property is only for virtual AP interfaces. WDS links also count toward this limit. Find and connect to acceptable AP. Same as station, but create WDS link with AP, using proprietary extension. AP configuration has to allow WDS links with this device. Note that this mode does not use entries in wds. Same as station, but additionally perform MAC address translation of all traffic. Allows interface to be bridged. Same as station- pseudobridge, but use station- bridge- clone- mac address to connect to AP. AP modes. ap- bridge - Basic access point mode. Same as ap- bridge, but limited to one associated client. Same as ap- bridge, but scan for AP with the same ssid and establishes WDS link. If this link is lost or cannot be established, then continue scanning. If dfs- mode is radar- detect, then APs with enabled hide- ssid will not be found during scanning. Special modes. alignment- only - Put interface in a continuous transmit mode that is used for aiming remote antenna. MAC address translation in pseudobridge modes works by inspecting packets and building table of corresponding IP and MAC addresses. All packets are sent to AP with the MAC address used by pseudobridge, and MAC addresses of received packets are restored from the address translation table. There is single entry in address translation table for all non- IP packets, hence more than one host in the bridged network cannot reliably use non- IP protocols. Note: Currently IPv. Pseudobridge. Virtual AP interfaces do not have this property, they follow the mode of their master interface. This option should be enabled only on access point, clients should be configured in station- bridge mode. Available starting from v. Value can be changed in future releases. Default: )name of the interfacenoise- floor- threshold (default . When setting is too small, clients that are farther away may have trouble connecting and/or disconnect with . Although during normal operation the effect of this setting should be negligible, in order to maintain maximum performance, it is advised to not increase this setting if not necessary, so AP is not reserving time that is actually never used, but instead allocates it for actual data transfer. When link is full with high priority queue data, lower priority data is not sent. Use it very carefully, setting works on AP. Mangle rules. Value of that property depends on the type of wireless card. Do not accept connections from clients that do not have this capability. Announce short preamble capability. On station. long - do not use short preamble. AP if it does not support short preamble. Use short preamble if AP supports it. W . This parameter controls how this information is included. It can interoperate with newer versions of Router. OS. This method is incompatible with some clients, for example, Centrino based ones. This uses standardized way of including vendor specific information, that is compatible with newer wireless clients. Default: MAC address of an interface)Descriptive name of the device, that is shown in registration table entries on the remote devices. Values from basic- rates and supported- rates parameters have no effect. Read more > >. For default scan list in 5ghz band channels are taken with 2. MHz step, in 5ghz- turbo band - with 4. MHz step, for all other bands - with 5. MHz step. If scan- list is specified manually, then all matching channels are taken. Using a comma to separate frequencies is no longer supported in Winbox/Webfig since v. Example: scan- list=5. Default: default)Name of profile from security- profilesssid (string (0. Default: value of system/identity)SSID (service set identifier) is a name that identifies wireless network. MAC; Default: )This property has effect only in the station- pseudobridge- clone mode. If this value is 0. MAC address of the wireless interface. Two devices will communicate only using rates that are supported by both devices. This property has effect only when value of rate- set is configured. It could help on the longer distance links, it could slightly increase bandwidth, while latency is increased too. Can damage the card if transmit power is set above rated value of the card for used rate manual- table - define transmit power for each rate separately. Can damage the card if transmit power is set above rated value of the card for used rate. Default: )How often to request update of signals strength and ccq values from clients. Refer to 8. 02. 1. MCS specification. Refer to 8. 02. 1. MCS specification. Port cost is recalculated and adjusted every 5 seconds if it has changed by more than 1. When WDS link is lost, wds interface is removed from the bridge. If wds interface is already included in a bridge setup when WDS link becomes active, it will not be added to bridge specified by , and will (needs editing)wds- default- cost (integer . If this property is set to yes, then SSID of the remote AP will not be checked. This property has no effect on connections from clients in station- wds mode. It also does not work if wds- mode is static- mesh or dynamic- mesh. Such dynamic WDS entries are removed automatically after the connection with the other AP is lost.- mesh modes use different (better) method for establishing link between AP, that is not compatible with APs in non- mesh mode. This method avoids one- sided WDS links that are created only by one of the two APs. Such links cannot pass any data. When AP or station is establishing WDS connection with another AP, it uses connect- list to check whether this connection is allowed.
