MTU The Maximum Transmit Unit (MTU) is the size of the
largest packet that can be sent over the network.
The standard MTU value for Ethernet networks is usually 1500 bytes. For PPPoE connections, the value is 1492 bytes.
Unless a change is required by your ISP, Cisco recommends that you choose Auto. The default MTU size is 1500 bytes.
If your ISP requires a custom MTU setting, choose
Manual and enter the MTU size.
Size Enter the MTU size.
Configuring the LAN Settings
The default DHCP and TCP/IP settings work for most applications. If you want another PC on your network to be the DHCP server, or if you want to manually configure the network settings of all of your PCs, disable DHCP.
Also, instead of using a DNS server, which maps Internet domain names (for example, www.cisco.com) to IP addresses, you can use a Windows Internet Naming Service (WINS) server. A WINS server is the equivalent of a DNS server but uses the NetBIOS protocol to resolve hostnames. The Cisco RV110W includes the IP address of the WINS server in the DHCP configuration the Cisco RV110W sends to DHCP clients.
NOTE If the Cisco RV110W is connected to a modem or device that has a configured
network on the same subnet (192.168.1.x), the Cisco RV110W automatically changes the LAN subnet to a random subnet based on 10.x.x.x, so there is no conflict with the subnet on the WAN side of the Cisco RV110W.
You can assign an IP address to each additional subnet on the Cisco RV110W.
