If you create a VAP for 2.4GHz or 5GHz radio the VAPs will be labelled athX.1 & athX.1 respectively where X = the interface's number. Ath0 is the 2.4GHz radio and ath1 is the 5GHz radio for most routers, for some like the TL-WDR4900 v1.3, ath0 is 5GHz & ath1 is 2.4GHz its just the way the radios are connected on the PCB & is normal. If you have a dual band router ath1 will be displayed below ath0 with the same available settings. Here is what it changes: Wireless Physical InterfaceĪvailable Interfaces: athX (0, 1, 2 etc, varies by router as many routers have 2 or more radios in them) The standard provides Dynamic Frequency Selection (DFS) and transmit Power Control (TPC) to the IEEE 802.11a MAC. It was originally designed to address European regulations but is now applicable in many other countries. It solves problems like interference with satellites and radar using the same 5 GHz frequency band. Here's some information on what 80211h was supposed to do: IEEE 802.11h is the IEEE standard for Spectrum and Transmit Power Management Extensions. For example, Canada's max allowed EIRP is 36 dBm while its max allowed TX power is 30 dBm, with Canada selected and antenna gain at 0 dBi, the radios will never go above 30 dBm assuming they are capable of reaching that of course.Īvailable Settings: Off, 802.11h Loose, 802.11h Strict, 802.11d Maximum EIRP varies by nation and your max TX power will be capped by the regulatory domain if you have a powerful radio. 24 dBm TX power with a 6 dBi gain antenna has an EIRP of 30 dBm.EIRP is TX power plus antenna gain, example: * 20 dBm TX power with a 10 dBi gain antenna has an EIRP of 30 dBm. This determines the channels available in the list for both bands (if you have a dual band router) and the maximum EIRP 'legally' allowed by the telecom authorities in the chosen country. See: Advanced Wireless Settings for the rest of the settings not found on this page.Īvailable Settings: 115+ different countries (several countries share the same regulations) Note, if you do not see a certain setting on your router, it may be on a different screen or it is not supported.
