Core Network Configuration

Backup and Prepare Network Configuration

Navigate to Config Directory:
```
cd /etc/config/
```
Save Current ULA Prefix:
```
cat network | grep -i "option ula_prefix"
```
- Note the ULA prefix value (e.g., fd44:9f52:3f1f::/48)
- Save this value - you'll need it for the new configuration
Create Backup:
```
cp network network.bak
```
Remove Original and Create New:
```
rm network
vim network
```

Copy the Complete Configuration: Replace the entire content with the configuration from your repository, making sure to:
- Replace the ula_prefix value with the one you saved earlier
- Verify all VLAN configurations match your port setup
Save:
- Save the file (:wq in vim)
Apply Network Changes:
```
uci commit network
/etc/init.d/network reload
```
- reload applies the new settings without completely rebooting the router
- If you notice that a certain interface doesn't come up properly, you can also do a full restart:
```
/etc/init.d/network restart
```
Optional: Check the status Check if your interfaces are up and have the correct IPs:
```
ifstatus wan
ifstatus lan
ifstatus iptv
```

After these steps, OpenWrt uses your new network configuration immediately.

Check Connection Status:
- Return to the GL.iNet web interface
- Navigate to INTERNET section
- Verify that you have an active internet connection
Test Internet Access:
- Open a web browser and test basic internet connectivity
- Run speed tests to verify performance
- Check that both IPv4 and IPv6 are working properly

Time Zone Configuration:
- In the GL.iNet web interface
- Set your correct timezone
- Save and apply changes
IGMP Snooping Settings:
- In the GL.iNet web interface
- Verify IGMP snooping is enabled on the LAN bridge
- Ensure IGMP version 3 is being used for optimal multicast performance
IPv6:
- In the GL.iNet web interface
- Enable IPv6 and set it to 'NAT6' Mode and DNS acquisition method to 'Automatic'
