and based on the type of the wireless client device, determining whether the wireless client device supports the wireless network feature. ### Claim 6 (depends on 1) The method of claim 1, further comprising: transmitting, by the wireless access point, at least one of: (a) one or more beacons or (b) one or more probe responses, which advertise the wireless network feature in a manner so that the wireless network feature is hidden from the one or more wireless client devices that do not support the wireless network feature. ### Claim 7 (depends on 1) The method of claim 1, further comprising: broadcasting, from the wireless access point, one or more beacons that advertise support for the wireless network feature in a specific information element of the one or more beacons. ### Claim 8 An apparatus comprising: a wireless transceiver configured to transmit and receive wireless signals in a wireless local area network; and a processor coupled to the wireless transceiver, wherein the processor is configured to adaptively enable a wireless network feature without advertising support for the wireless network feature in a wireless network-standard compliant manner, wherein the wireless network feature is supported by a first wireless local area network standard and is not supported by a second wireless local area network standard and such that the wireless network feature is enabled for one or more wireless client devices that support the wireless network feature and is hidden from one or more wireless client devices that do not support the wireless network feature. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the processor is configured to enable the wireless network feature by: obtaining a probe request from a wireless client device; evaluating data contained in the probe request to determine whether the wireless client device supports the wireless network feature; enabling wireless network connectivity with the wireless network feature for the wireless client device based on determining that the wireless client device supports the wireless network feature; and enabling the wireless network connectivity without the wireless network feature for the wireless client device based on determining that the wireless client device does not support the wireless network feature. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the processor is configured to evaluate the data contained in the probe request by determining whether an address of the wireless client device included in the data of the probe request is included in stored data that identifies wireless client devices which support the wireless network feature. ### Claim 11 (depends on 9) The apparatus of claim 9, wherein the processor is configured to enable the wireless network connectivity without the wireless network feature by providing one or more probe responses that do not include information signifying support of the wireless network feature. ### Claim 12 (depends on 9) The apparatus of claim 9, wherein the processor is configured to evaluate the data contained in the probe request by: determining a type of the wireless client device by comparing a signature or pattern included in the data of the probe request with signatures or patterns included in stored client probe requests;
