WiFi 6 AX1800 Dual Band Wireless Access Point WAX204 Note: An incorrect MTU setting can cause Internet communication problems. For example, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers. To change the MTU size: 1. Launch a web browser from a computer or mobile device that is connected to the access point network. 2. Enter http//www.routerlogin.net in the address field. If you are not connected to the access point network but to the same network as the access point, enter the IP address that is assigned to the access point. If you do not know the IP address, see Find the IP address of the access point when you cannot use routerlogin.net on page 27. A login window displays. If your browser does not display the login window but displays a security message and does not let you proceed, see Log in to the access point after initial setup on page 30. 3. Enter the access point local device password. The local device password is the one that you specified. The local device password is case-sensitive. The BASIC Home page displays. 4. Select ADVANCED > Setup > WAN Setup. The WAN Setup page displays. 5. In the MTU Size field, enter a value from 616 to 1500. The default size is 1500 bytes. 6. 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.
