When access points overlap, they can be configured to help optimize the network by sharing and managing loads.Ī mesh network extends a WLAN's reach and performance, through the use of numerous access points that connect with each other wirelessly. Even with nonoverlapping access points, a user's connection is simply paused until connection with the next access point.Īdditional access points can be wired or wireless. Wi-Fi standards are designed to allow a nonstationary user's connection to jump from one access point to another, though some users and applications may experience brief dropouts. The most common security method for a WLAN is encryption, including Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA), with WPA2 as the standard authentication method.įor any sized network, access points can extend the area of access. However, determined adversaries may be able to join networks by spoofing an authorized address. The most basic method of securing a WLAN is to use MAC addresses to disallow unauthorized stations. To access a WLAN, a bad actor must simply be within range of the network. With a wired network, a bad actor must gain physical access to an internal network or breach an external firewall.

My product is a security product, and we want to be able to identify a specificĪccess point by mac address, not just ssid, before we connect to it.Īny insights on how to do this with WLAN would be greatly appreciated.A WLAN is more vulnerable to being breached than a physical network. Listings with the same ssid, even when there is only one ssid with The WlanGetAvailableNetworkList function often returns multiple This problem is exaserbated by a bug in the WLAN API.

So we should use the same MAC address of addr2 and addr3 because the sender is the access point We create our beacon frame with SSID Infos. addr3: the MAC address of the access point. addr2: source MAC address, the senders MAC address. The same SSID present, there is no way that I can tell to distinguishĪmoung them. If you want this fake access point to appear only in a target device, you can use the targets MAC address. There is another problem with the WLAN api.

Newer network adapter Vista drivers don't support the 802_11 family of OIDs at all.

I can do it on pre-Vista windows using the third party Rawether product, but I'm finding that WLAN_REASON_CODE wlanNotConnectableReason ĭOT11_PHY_TYPE dot11PhyTypes ĭOT11_AUTH_ALGORITHM dot11DefaultAuthAlgorithm ĭOT11_CIPHER_ALGORITHM dot11DefaultCipherAlgorithm Īs near as I can tell the access point MAC address isn't available in this struct.Īm am I correct, or am I missing it somewhere? I'd sure like to beĪble to detect the mac address of an access point without connecting to it Using Vista's WLAN API we our scan data is obtained by calling WlanGetAvailableNetworkList, which returns an array of WLAN_AVAILABLE_NETWORK objects, define as:

The 802.11 spec for this value is NDIS_802_11_MAC_ADDRESS, which is part of the data structure which the 802.11 specs call NDIS_WLAN_BSSID_EX. Wifi access points transmit their MAC address as part of their beacons.
