The first 3 ports are RJ11 (6P6C/6P4C/6P2C) Jack. These ports are normally
used with an RJ11 connector (telephone line).
The 4 yellow ports are RJ45 (8P8C/8P4C) Jack. These ports are normally used
with an RJ45 connector (Ethernet cable).

Configuration| 6P4C (6 positions, 4 conductors)| 8P8C (8 positions, 8
conductors)
---|---|---
Usage| Phones, ADSL/VDSL lines, modem cables. RJ11 is
mostly used for voice applications.| Computer networking. RJ45 is used in
Ethernets or connecting
cable/fiber modems or NBN box with Wi-Fi routers.
Bandwidth| RJ11 connectors can support about 100+Mbps| RJ45 connectors can
support up to 10Gbps over Ethernet,
provided the other equipment like network cables also support
that speed.
Shape and size| Compact, square-shaped| Longer, more rectangular
- RJ45 is mostly used with Ethernet cables while RJ11 is connecting to telephone units.
- RJ45 has 8 wires inside while Rj11 has 4 wires.
- RJ45 is bigger in size than RJ11.
- You cannot plug-in the RJ45 cable connector into an RJ11 jack/interface/port/slot, however, you can do the opposite. Plugging an RJ11 cable into an RJ45 jack/interface/port/slot is the most common mistake that might happen. It will not work by doing so and it might also damage the RJ45 port as power is being delivered by the telephone company into your handset that allows it to function even during a power outage.
