Mobile network connection
A SIM card lets the router provide internet access where a wired connection is unavailable, such as a home or office with mobile network coverage.
Actual internet speed and stability depend not only on the router but also on signal strength, network congestion and the terms of the operator’s data service. Before choosing a SIM card, check coverage and data plan conditions at the location where you intend to use it.
300 Mbps Wi-Fi and two frequency bands
The stated 300 Mbps is a maximum Wi-Fi connection speed, not a guaranteed LTE internet speed. Actual wireless performance is affected by factors such as distance from the router, obstacles and interference from other networks.
Support for the 2.4 GHz and 5 GHz bands lets you choose a connection suited to your environment and device. The 2.4 GHz band generally offers better range, while 5 GHz may be a useful choice at shorter distances or where there is interference on 2.4 GHz. Results depend on the conditions at the location.
The router can be used for everyday web browsing, video streaming and working from home. For these activities, mobile connection quality and the number of devices in use at the same time also matter.
Setup and security
The router is managed through a web interface where you can change network settings. To get started, insert a SIM card, connect the power supply and configure the network through the router interface as needed.
The device supports WPA2 Wi-Fi encryption. When setting up the network, use a strong Wi-Fi password and change the password used to access the router’s administration interface. WPA2 helps protect the wireless connection against unauthorised access, but it does not by itself guarantee complete protection for devices or data.
Network features also include dynamic IP addressing and network masquerading. Masquerading allows devices on the local network to share a connection, but it does not replace other security measures.
Antennas, cable and power
The OPTFOCUS router has two external antennas. Their placement can affect signal reception, so it is worth trying the router in a position with good mobile coverage.
A 1-metre Ethernet cable is included for connecting a device by cable. The power adapter has a European plug and is rated for 220–240 V at 50–60 Hz. Check that the plug and voltage are compatible with your location.
The router is an alternative to fixed internet where a suitable mobile data service is available. Before choosing it, check mobile coverage, operator compatibility, SIM card format and available ports.
