IP Management
The basic settings define the identity of the router within the local network (LAN). Here you can configure the router IP address, subnet mask and the DHCP server.
In the router portal under the tab Network → Basic Settings.
Overview of Basic Settings
| Setting | Value | Description |
|---|---|---|
| Router IP address | 192.168.1.1 | The primary IP address of the gateway in the LAN. |
| Subnet mask | 255.255.255.0 | Defines the subnet (/24), which allows up to 254 hosts. |
IPv4 Address Assignment (DHCP)
The DHCP server automates the assignment of IP addresses to connected devices. The default configuration is defined as follows:
| Parameter | Value | Description |
|---|---|---|
| DHCP status | Enabled (On) | DHCP is active by default |
| DHCP range (start) | 192.168.1.33 | First dynamically assigned address |
| DHCP range (end) | 192.168.1.127 | Last dynamically assigned address |
| Gateway | 192.168.1.1 | Corresponds to the router IP |
| DHCP lease duration | 86400 seconds | Corresponds to 24 hours |
Notes on the DHCP Range
The defined range (.33 to .127) provides space for 95 dynamic IP addresses. When planning static IP addresses (for servers, printers or network devices), addresses outside this range should be chosen to avoid IP conflicts:
- Static devices:
.2to.32(31 addresses) - Additional range:
.128to.254(127 addresses)
If the DHCP range is changed, already connected devices will only receive a new address after their current lease duration expires. A device restart or ipconfig /renew (Windows) forces an immediate renewal.
Static Address Assignment (DHCP Reservation)
For devices that should always receive the same IP address (e.g. printers, servers, IP cameras), a static DHCP assignment can be configured. The MAC address of the device is linked to a fixed IP address.
- In the router portal under Network → Basic Settings
- In the DHCP section, select the Static Assignment option
- Enter the MAC address of the device and the desired IP address
- Confirm with Save
Limitations
- Not available with BNS/EC-S contracts
FAQ – IP Management
What happens when I change the router IP address?
After the change, the router portal is accessible at the new IP address. The connection to the portal is briefly lost. All devices on the network automatically receive the updated network settings (new gateway) via DHCP.
How do I find the MAC address of a device?
- Windows:
ipconfig /allin the command prompt → "Physical Address" - macOS: System Settings → Network → Advanced → Hardware
- Smartphone: In the Wi-Fi settings under network details
Can I disable the DHCP server?
Yes, but then all devices on the network must be manually assigned a static IP address. This is only recommended for special network setups (e.g. when an external DHCP server is used).
Why are devices not receiving an IP address?
Possible causes:
- The DHCP address pool is exhausted (all addresses assigned)
- The device is not in the same subnet
- The DHCP server is disabled
- An IP address conflict exists
