OID_WW_TAC_ANTENNA_MODE
As a query, the OID_WW_TAC_ANTENNA_MODE OID requests the miniport driver to return the NIC's current antenna-selection algorithm.
As a set, this OID requests the miniport driver to change the NIC's current antenna-selection algorithm.
This request uses a WW_TAC_ANTENNA_MODE data type, defined as equivalent to an INT.
For either a query or a set, this request uses one of the following values:
| Value | Meaning |
|---|---|
0 |
Automatic antenna selection |
1 |
Always use primary antenna |
2 |
Always use secondary antenna |
-1 |
Antenna algorithm currently unknown |
Typically, this OID can be used to either temporarily change which antenna the NIC currently uses for debugging purposes or to select an alternate antenna if the antenna that is currently in use fails to operate correctly. During sets, a value of unknown, that is -1, is invalid; the miniport driver should return an error of NDIS_STATUS_INVALID_DATA.
Indications are irrelevant for this OID.
Note This OID is not available for use beginning with Windows Vista.
