Verification Process Verifying Wi-Fi Operation Verifying Wi-Fi Operation After installing and configuring the Vivato Wi-Fi AP/Bridge, it is important to verify that it operates as intended. The information in this section is intended to help you verify Wi-Fi AP/Bridge operation and provides ideas to troubleshoot any configuration problems that you may have. Use your Wi-Fi client’s documentation to understand its configuration settings.
Verification Process Verifying Wi-Fi Operation Wireless Client Does Not “Find” the Vivato Wi-Fi AP/Bridge Part of configuring the Wi-Fi AP/Bridge involves entering the extended service set identifier (ESSID) for each wireless interface. This is the name that is displayed on your client’s list of available Wi-Fi networks. The following conditions must be present for the ESSID to be displayed on your client’s network list. • The Wi-Fi AP/Bridge’s power LED must indicate that the AP/Bridge is operating.
Verification Process Verifying Wi-Fi Operation Wireless Client Can’t Access Wi-Fi AP/Bridge Configuration Web Page For your client to associate with the Vivato Wi-Fi AP/Bridge, the following conditions must exist: • The IP address of your wireless client must be within the same subnet range of the Wi-Fi AP/Bridge. The default IP address of the Wi-Fi AP/Bridge is 169.254.20.1.
Verification Process Verifying Wi-Fi Operation network (LAN) server. If your server uses an access list to allow access to the network, make sure that the Wi-Fi AP/Bridge has been added to that list. • When authenticating through a RADIUS service, the RADIUS configuration information must be correctly entered. See "Security>802.1x" on page 72. • The correct default gateway is specified. See "Basic Network Setup" on page 46.
How Does DHCP Work? Dynamic Assignment of Client IP Addresses Dynamic Assignment of Client IP Addresses In order to communicate with the AP/Bridge, servers, and other devices on a network, clients must be configured to have an IP address within the same address range that is used by those devices. This is similar to a telephone connection, where only certain phone number prefixes are used within an area code to allow callers to talk to each other without being routed through long distance lines.
What is Network Address Translation? Dynamic Assignment of Client IP Addresses The Vivato Wi-Fi AP/Bridge can be configured as a DHCP server. In conjunction with network address translation (NAT), this allows a totally different range of IP addresses to be used by your wireless clients than are used by your wired network. This results in only one IP address being used for all traffic to/from the AP/Bridge’s connection to the wired network.
“Breaking the Bridge” Dynamic Assignment of Client IP Addresses “Breaking the Bridge” As shown below, the AP/Bridge’s default configuration connects the Ethernet port (eth0) to both wireless interfaces (wlan0 & wlan1) using a bridge called “br0”. Routing, Security, HTTP & SSH Services, and other AP/Bridge operations. br0 eth0 192.168.8.
Configuring DHCP Server Operation on the AP/Bridge Dynamic Assignment of Client IP Addresses Configuring DHCP Server Operation on the AP/Bridge The following steps are used to configure DHCP server operation to provide client IP addresses. Entries marked optional indicate setting that are not absolutely necessary to have DHCP server operation working, but may be needed to access some wired network features.
Configuring DHCP Server Operation on the AP/Bridge Dynamic Assignment of Client IP Addresses DHCP Server Configuration Example The following CLI configuration example shows how the AP/Bridge can be configured to act as a DHCP server for clients connecting to the network shown below. 10.0.4.1 DHCP Server/ Name Server 10.0.4.2 10.0.4.3 192.168.8.185 Gateway/ Authentication Server 10.0.4.4 192.168.8.6 eth0 AP/Bridge Internet Ethernet 192.168.8.245 eth0: 192.168.8.7 br0: 10.0.4.250 192.168.8.5 192.
