One of the most common questions for new Fairino users — how to actually connect to the robot's WebApp from a laptop. This guide is based on troubleshooting dozens of setups across different hardware generations and firmware versions.
Default IP addresses
The Fairino control box has two Ethernet ports with default IPs:
- Port 0 (NIC 0):
192.168.58.2— usually runs the WebApp - Port 1 (NIC 1):
192.168.57.2— usually runs Web Recovery
The WebApp runs on port 8055 by default. So the full URL is:
http://192.168.58.2:8055In some configurations (especially older systems set up by Chinese integrators like Hebei Hanna Technology), the IP may be different — e.g. 192.168.58.33:8055 or 192.168.58.34:8055. The teach pendant IP is often 192.168.58.77.
Laptop configuration — step by step
- Connect an Ethernet cable from your laptop to one of the control box RJ45 ports
- Open Network Settings → Ethernet adapter → IPv4 → Properties
- Set a static IP in the same subnet:
- IP:
192.168.58.100(or any address not used by the robot) - Mask:
255.255.255.0 - Gateway: leave blank
- IP:
- Open a terminal and ping the robot:
ping 192.168.58.2 - If ping succeeds, open Chrome and go to
http://192.168.58.2:8055
Troubleshooting checklist
If it doesn't connect, go through these in order:
| Problem | Solution |
| Ping fails completely | Check cable, verify your IP is in the same subnet (192.168.58.x) |
| Ping works but browser won't load | Disable Windows Firewall — this is the #1 cause. Or add an exception for the subnet. |
| Still nothing after firewall | Try the other Ethernet port on the control box. WebApp may be on port 0 or port 1 depending on configuration. |
| Port is not 8055 | Use PowerShell to scan: Test-NetConnection 192.168.58.2 -p 8055, also try ports 8050, 80, 443 |
| Non-default IP addresses | If the system was configured by someone else, the IPs may differ. Check the teach pendant display or try both .57.x and .58.x subnets. |
Newer vs older control boxes
New mini control box: Has one Ethernet interface on the safety box and two RJ45 connectors on the box itself working as a switch. Both RJ45 ports share the same network.
Standard control box: Two independent Ethernet interfaces — first RJ45 = one interface, second RJ45 = second interface. Each has its own IP.
Old control box (pre-2022): May have a non-standard setup. One port may be hardwired internally to the teach pendant connector. The button/safety box may or may not have a UTP port. In the worst case, you can only connect your laptop where the teach pendant normally plugs in (meaning you can't have both connected).
Connecting via WiFi simultaneously
You can use WiFi for internet and the Ethernet port for the robot at the same time — Windows handles this automatically as long as the subnets don't overlap. You can also configure multiple IP addresses on a single Ethernet adapter (Advanced TCP/IP settings → Add) if you need to access both .57.x and .58.x subnets.
For mobile access at a customer site, a small WiFi access point (like a MikroTik box) connected to the control box lets you access the WebApp from a tablet while walking around.
IP reset to factory defaults
If the IPs have been changed and you can't find them, hold the IP reset button on the safety box for ~30 seconds. The procedure differs between old and new safety boxes — check the manual for your specific version:

Default login credentials
- WebApp:
admin/123 - Some systems may use password:
