Note: This MTU is applied on wired connections only. For Mobile Broadband, MTU is
negotiated with the 5G/LTE provider.
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 your
Orbi network.
2. Enter orbilogin.com.
A login window opens.
3. Enter the admin user name and password.
The user name is admin. The password is the one that you specified the first time
that you logged in. The user name and password are 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 64 to 1500.
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.
