Fragmentation Threshold Default setting is bytes and the allowed range is bytes. It specifies the maximum size for a packet before data is fragmented into multiple packets. For your testing, you can set this threshold to bytes and then check the result. Should Wmm be enabled? WMM is the default setting of the modem and should be left enabled. The issue you have is that when WMM is enabled, you get occasional lag. What is WPS button? It is designed to make the process of connecting to a secure wireless network from a computer or other device easier.
What is Beacon period setting? What is the best RTS threshold setting? The recommended standard of the RTS threshold is around A low threshold implies RTS packets are transferred more frequently and the throughput of the packet is on the lower side. What is AP isolation? The AP Isolation is a feature of wireless routers that enables you to create a separate virtual network for each wireless client that is connected to a network name or SSID.
When this feature is enabled, all wireless devices in the network will not be able to communicate with each other, preventing unwanted hacking. DTIM stands for Delivery traffic indication map or message.
It is basically an additional message added after the normal beacon broadcast by your router or access point. The default value is 3. What are beacons used for? What Is Beacon Technology? Beacons are small, wireless transmitters that use low-energy Bluetooth technology to send signals to other smart devices nearby. TIM element contains information useful for stations in low-power mode. As you can see below it has following fields a.
Element ID 1 byte b. Length 4 byte c. Partial Virtual Bitmap byte — represent stations in low power mode for which AP has traffic buffered.
Country Each country has regulatory bodies that limit the channels or power levels allowed in their regulatory domain. This is not a mandatory field in a beacon. Power Constraint 3 byte This element is related to So to avoid interference with those systems AP should operate max power specified by these constraint fields.
Channel Switch 6 byte This is also related to When a radar blast is detected, all stations must leave the affected channel. The AP can set to announce to the cell which is the next channel. Quite 8 byte Another element related to TPC Report 4 byte This element is also related to A nonERP station legacy A neighboring cell is detected, allowing only nonERP data rates c. Any other management frame except probe request is received from neighboring cell supporting only nonERP data rates.
It is only required if there are more than 8 supported rates. It provides information on the cell load, from the AP point of view. It has following subfields a. Station Count — How many stations are currently associated b. Available Admission Capacity —. QoS capability This element is used only when QoS is supported. Mobility Domain If AP supporting HT Capability Used in HT Operation Used with VHT Operation Used with Giovanni di Marzio said:.
October 30, at pm. Thank you! Pingback: How do wifi clients detect APs? Joe Chiarelli said:. June 9, at am. Ive disabled B mode support on a router, and i still see 1 B , 2 B ,5.
Can you explain why disabling B mode does? I also notice it had rates for 6 B and 12 B , making them mandatory too. Hari said:. October 29, at pm. December 16, at pm.

I am trying to do the same in wireshark but it seems in ubuntu, latest version of wireshark is not showing the Radio measurement field in capability info. But in the capability info value I can see radio measurement enable. Also in response the mobile devices which supports radio measurement are sending radio measurement bit enabled and devices not supporting are not enabling the same bit. In wireshark, I can see Capabilities Information : in beacon packet which shows that AP supports radio measurement.
In the bit description of capability info bits just below, I can see some bits like 1: ESS capabilities, 1: Short Slot time etc. March 4, at pm. March 21, at pm. Joe said:. April 12, at pm. And i do not know how to set the Qos info. April 21, at pm. June 25, at pm.
What is the maximum power supported by the country by reading the beacon Country Thanks. Madhusudhanan Sampathkumar said:. December 21, at pm. Likewise if Post as a guest Name.
