Accessing Meshlium - make it easy!

Meshlium comes with all the radios ready to be used. All the Meshlium units come with the WiFi Access Point ready, so that users can connect using their WiFi devices. Connect the Ethernet cable to your network hub, restart Meshlium and it will automatically get an IP address from your network using DHCP.

Then access Meshlium through the WiFi connection. First of all, search the available access points and connect to "MeshliumXXXX". The four digits at the end allow to identify different Meshliums when working near each other.

No password is needed as the network is open (you should change it later in the WiFi AP interface options). When you select it, Meshlium will give an IP address from the range -

Manager System is now securized with HTTPS. Accessing Manager System requires configuring your browser with a certificate. Please read the next section to learn the process.

Configure your browser to trust the Meshlium Manager System's self-signed certificate

HTTP Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication (protocol is encrypted using TLS or SSL) over a computer network, and is widely used on the Internet. Web browsers know how to trust HTTPS websites based on security certificates that come pre-installed in their software. Those certificates have been created by a Certificate Authority (CA). Certificate authorities are in this way being trusted by web browser creators to provide valid certificates.

Most web browsers alert the user when visiting sites that have certificates issued by authorities not pre-installed. The communication is still secured, but the user needs to install the CA certificate in the browser (Firefox, Chrome, etc) to avoid the warning message. Meshlium devices are provided with a self-signed certificate to serve Manager System, providing protection of the privacy and integrity of the exchanged data while in transit. That protects against man-in-the-middle attacks, eavesdropping and tampering for all the communications between the user and Meshlium.

Therefore, you will have to accept the Meshlium's self-signed certificate in your browser. Follow the instructions below for adding the Meshlium certificate in the most widely used browsers.
