I’m trying to diagnose a problem with my Balance One where it only can pass about 250mbps of traffic. See Balance One Core Underperforming Throughput
As a result, I’ve been poking around at all my settings, and realized that for both of my networks,
WAN / [Network] / Physical Interface Settings / MTU Is set to Custom: 1440.
I’m 99% sure I never made this change - while I do vaguely understand what MTU is, I’m sure I never changed it.
- I’m assuming that Auto is the default, right?
- I have two WANs, cable and fiber, both from Spectrum. What’s the best MTU. Should I set it back to Auto?
- How did this get set to a Custom value. Is this a bug in one of the firwmare updates I’ve done?
- Is anyone else seeing this?
