Sym ptom There are cases in w hich it is not possible for a client computer that is connected to the same LAN to connect to the Internet after starting to use the Access Point previously connected to a LAN. HANDLING Is the DHCP server operating on the LAN? Also, check the connection settings for the Wireless LAN Access Point. Is it set to Phone mode or to Local Only mode? Regarding these modes, the Access Point functions as the DHCP server for the Ethernet side and in the default settings, the IP addresses from 10.0.1.2 to 10.0.1.17 are assigned to the clients. For that reason, the follow ing connections exist. 1. The Access Point responds to the client PC IP address request before responding to the LAN's regular DHCP server. 2. If the IP address assigned by the Access Point does not match the LAN IP address, that client does not exist on the LAN. Therefore, it is not possible for the client to check their mail or to access the Internet. When connecting the Access Point to the company's existing LAN line, refer here for details. In the meantime, you can remove the Access Point from the LAN and re-acquire the client computer's IP address. Refer here for details on how to acquire the IP address. Changing the IP address setting of the Access Point disabled com m unications from the com puter. The IP address may not match the Access Point and the computer. Try either of the follow ing: 1.
