!!! warning
Mountain Mesh members are migrating from the default LongFast modem preset to MediumFast on October 1, 2025. We're keeping LongFast settings here for now until the migration date. For more information, see the [MediumFast Migration Page](/mediumfast)

**MediumFast Config**
As of October 1, 2025, Mountain Mesh members flipped their nodes over to the MediumFast modem preset. For more information, see the [MediumFast Migration Page](/mediumfast)

| Option | Recommended Config | Notes |
| -------------: | :----------------- | :----------------------------------------------------------------------------------------------- |
| Modem Preset | MEDIUM_FAST | This is the new fast network |
| ^^Hop limit^^ | `5` | Please do not set this higher than `6`. :pray: |
| Frequency Slot | 45 | This is the default. It equates to 913.125 MHz |
| Ignore MQTT | `True` | This is enabled on most `ROUTER` nodes in our mesh. |
| OK to MQTT | `True` | Added in `2.5.0`. Enable to show up on online tools like [info.MtnMe.sh](https://info.mtnme.sh). |

## Why We're Moving Modem Presets
## Why We Moved Modem Presets

All Meshtastic devices default to LongFast out of the box. That's a great preset for getting a small mesh off the ground, but once you get more than 60 nodes chatting in an area, you start getting message collisions. More collisions means dropped packets, network congestion and decreased performance. Considering that some node DBs have more than 200 nodes and channel usage above 45%, we're well past that threshold for migration.
