Many MikroTik setup problems start with one simple issue — the router is not receiving internet. Learn how DHCP Client works and how to confirm your WAN connection before starting configuration.

When setting up a MikroTik router in many installations, people immediately start configuring hotspot settings, DHCP servers, or firewall rules. However, before running any configuration scripts, especially XenFi scripts for remote access or automated router setup, the router must already have a working internet connection.
This is where DHCP Client becomes important.
DHCP stands for Dynamic Host Configuration Protocol.
A DHCP Client is a feature that allows a device—in this case your MikroTik router—to automatically receive network information from an ISP or upstream router.
When DHCP Client is enabled:
An IP Address
A Gateway
DNS servers
Network lease information
This allows the router to access the internet without manually configuring these values.
At XenFi, we use scripts that prepare the router for hotspot deployment and remote management.
These scripts need the router to already be connected to the internet because the router must be able to:
Execute remote setup scripts
Enable remote access
Complete automated router configuration
If the router does not have internet access, the scripts will not run successfully.
In most MikroTik installations, the internet cable from the ISP is connected to:
ether1
This port usually acts as the WAN port, meaning it is responsible for bringing internet into the router.
Your computer or laptop is normally connected to another port such as; ether2, ether3, ether4, ....
This allows you to access the router using WinBox.
To confirm the router is receiving internet:
Open WinBox
Connect to the router
Navigate to:
IP → DHCP Client
Here you should see the DHCP Client configured > ether1 (or whichever port is used for WAN).
Once DHCP Client is active, Mikrotik will attempt to obtain an IP address from the ISP.
If everything is working correctly, the status will show:
Status: bound
This means the router has successfully received network information from the ISP.
You will also see:
The assigned IP address
The gateway
The lease time
When DHCP Client receives an IP address, it is given a lease time.
This lease time counts down on the DHCP Client screen.
The countdown simply indicates how long the router can keep using the assigned IP address before renewing it with the ISP.
This is completely normal and shows that the DHCP connection is active.
When the timer expires, the router automatically renews the lease.
If the status shows Searching, it means the router is not receiving internet.
Common reasons include:
ISP cable plugged in wrong port
Internet service from ISP is down
DHCP Client not configured on correct interface
ISP cable not fully plugged in
Before configuring hotspots or running XenFi scripts, confirming DHCP Client ensures that:
The router is online
The WAN port is working
Internet connectivity is available
XenFi scripts can execute properly
Skipping this step can lead to failed setups and unnecessary troubleshooting.
DHCP Client may look like a small detail in MikroTik configuration, but it plays a critical role in ensuring the router is properly connected to the internet.
For XenFi deployments, confirming that the DHCP Client is bound and receiving internet is a key step before running setup scripts or configuring hotspot services.
A simple check here can save time and ensure a smooth deployment process.
