## Roles
Leave your [ROLE](/docs/configuration/radio/device#roles) set to `CLIENT` unless you're sure another role would suit the node's purpose. All `CLIENT` nodes will "repeat" and "route" packets. Roles are for very specific applications so please [read the documentation](/docs/configuration/radio/device#roles) before changing your node's role.
It is strongly recommended to keep your [ROLE](/docs/configuration/radio/device#roles) set to `CLIENT`. Only change this if you have a specific, well-understood reason to do so.
:::info
### Why `CLIENT` is Recommended
Users report that the current implementation of the `ROUTER` role with bluetooth switched off causes instability. If you would like the functionality associated with this role, it is recommended you choose `ROUTER_CLIENT` until a firmware fix is issued.
- `CLIENT` nodes efficiently repeat and route packets as needed.
- They use smart delays for rebroadcasting, improving network stability.
:::
### Avoid `ROUTER`, `ROUTER_CLIENT`, and `REPEATER`
Using `ROUTER`, `ROUTER_CLIENT, or `REPEATER` roles unnecessarily can cause serious network issues:
- Increased risk of packet collision.
- Reduced message delivery rates.
- Decreased effective network range due to unnecessary hop consumption.
These roles are for very specific applications. Before changing from `CLIENT`, carefully [review the documentation](/docs/configuration/radio/device#roles) to understand the implications. Additionally, coordinating this with your local community to ensure its impact is a positive one rather than a negative one.
Remember: A network of `CLIENT` nodes with a small number of well-placed `ROUTERS` is usually the most efficient and stable configuration.
## (Not) Sharing Your Location
Telemetry is shared over your [PRIMARY channel](/docs/configuration/radio/channels#role). This means that if your node has acquired GPS coordinates from an integrated GPS chip, or from your mobile device, your coordinates will be sent to the mesh over this channel, using it's defined encryption (if any).

This means that if your node has acquired GPS coordinates from an integrated GPS chip, or from your mobile device, your coordinates will be sent to the mesh over this channel, using it's defined encryption (if any).
By default the PRIMARY channel's name is LongFast with the encryption key "AQ==" (Base64 equivalent of Hex 0x01). If this is left unchanged, your location will be shared with all nodes in range that are also using the default channel.

### Using Position Precision
Meshtastic now supports the ability to control the precision of location data sent over a particular channel.
The `position_precision` setting allows control of the level of precision for location data that is sent over a particular channel. This can be useful for privacy reasons, where obfuscating the exact location may be desired when sending position data over certain channels.
For detailed information on position precision settings and how to configure them, please refer to the [Position Precision documentation](/docs/configuration/radio/channels/#position-precision).
### Creating a Private Primary with Default Secondary
If you'd like to connect with other Meshtastic users but only share your location with trusted parties, you may create a private PRIMARY channel and use the defaults for a SECONDARY channel.
Alternatively, if you wish to only share your location with trusted parties, you may create a private PRIMARY channel and use the defaults for a SECONDARY channel.
1. Ensure you have not changed the LoRa [Modem Preset](/docs/configuration/radio/lora#modem-preset) from the default `unset` / `LONG_FAST`.
2. On your PRIMARY channel, set anything you'd like for the channel's name and choose a random PSK.

Meshtastic nodes will rebroadcast all packets if they share [LoRa modem settings](/docs/configuration/radio/lora#lora-config-values), regardless of encryption (unless [Rebroadcast mode](/docs/configuration/radio/device#rebroadcast-mode) is set to `LOCAL_ONLY`).

If you would like your nodes to include/expand the "public" mesh, you must use the default [modem preset](/docs/configuration/radio/lora#modem-preset) `LONG_FAST`. If you change your PRIMARY channel name, you must manually set the LoRa channel to the default for your region (see above).

### Hop Count
It is **strongly** recommended to leave your [MAX HOPS](/docs/configuration/radio/lora#max-hops) set to 3 unless you're sure you need more (or less) to reach your destination node. Unnecessarily high hop counts often lead to network issues.
## Chat Channels and LoRa Frequency Slots
Previously, Meshtastic used the word "channels" to define two different configuration properties: Messaging Channels & LoRa Channel Numbers. However, this could lead to confusion since "channels" was being used to refer to two distinct concepts. To clarify the distinction, the decision was made to change "LoRa Channel Number" to "LoRa Frequency Slot".

This property, formerly known as "LoRa Channel Number", configures the frequency the radio is set to. Check out the [frequency calculator](/docs/overview/radio-settings#frequency-slot-calculator) to view the relationship between "frequency slot" and radio frequency.
## Best Practices
- If you are part of a large mesh and don't know what a setting does, don't change it (unless you're super curious).
- Leave your [MAX HOPS](/docs/configuration/radio/lora#max-hops) set to 3 unless you're sure you need more (or less) to reach your destination node.
- TEST your settings and hardware before you install in hard-to-reach locations.
- Connecting a node to the [public MQTT server](/docs/configuration/module/mqtt#connect-to-the-default-public-server) may publish the locations of all nodes in your mesh to the internet. This will also add every globally connected node to your node database and potentially flood your mesh with all types of packets.
