AC2000 802.11ac Wireless Access Point/Router WAC124 To change the MTU size: 1. Open a web browser from a computer or mobile device that is connected to the access point/router network. 2. Enter http://www.routerlogin.net in the address field. If you are not connected to the access point/router network but to the same network as the access point/router, enter the IP address that is assigned to the access point/router. If you do not know the IP address, see Find the IP address of the access point/router on page 29. The Sign-In page displays. You are prompted to sign in with your NETGEAR account. If the access point/router is not connected to the Internet, you are prompted to sign in with the local login credentials (see Log in to the access point/router when it is not connected to the Internet on page 28). 3. Click the Login button. The NETGEAR Account Login page displays. 4. Enter your registered email address and password and click the LOG IN button. The BASIC Home page displays. 5. Select ADVANCED > Setup > WAN Setup. The firewall Basic Setup page displays. 6. In the MTU Size field, enter a value from 616 to 1500. The default size is 1500 bytes. 7. Click the Apply button. Your settings are saved. If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away. The following table describes common MTU sizes and applications. Table 2. Common MTU sizes MTU 1500 1492 1472 Application The largest Ethernet packet size. This setting is typical for connections that do not use PPPoE or VPN and is the default value for NETGEAR routers, adapters, and switches. Used in PPPoE environments. Maximum size to use for pinging. (Larger packets are fragmented.) Manage the Network Settings 129 User Manual
