Access method and access device of wireless network

The invention discloses an access method of a wireless network. The access method is applied on a wireless access end and comprises the following steps: saving MAC (multi-access computer) address at a special client side without cryptographic authentication into a MAC address table in advance; receiving authentication request messages carrying client-side MAC address information sent by the client side; and permitting the client side to access the wireless network in non-authenticated and non-encrypted mode if the MAC address at the client side is the MAC address in the MAC address table. With the adoption of the wireless network access method, the client side which is inconvenient to input passwords can be automatically recognized, and the client side can conveniently access the wireless network. The invention also provides an access device of the wireless network.
