Hi @MyPack
Thank you for your post and welcome to the Community.
While there is no formal option for checking the length of a connection, you can select the "My devices" option through the modem GUI to check what devices are actively connected to your modem. Please note that unless you physically disconnect a device from the Wi-Fi, generally most devices just stay connected, whether it is being used or not). Alternatively, if you're familiar with how to read a system log, you can also go into the "Advanced tools and settings" option through the modem GUI and select "System logs" and you can look through to see things such as devices and when they connect and disconnect, although it shows the MAC ID's.
To check your usage in your modem GUI you would select the "My usage" button. Another screen will pop up and at the top left, you can change the range from '30 days' to 'today, this week, next week, last month, etc..' and it will show each device's upload / download bandwidth usage.
There is no option for checking the browser history through the modem. This is something you would need to check directly on the device, through the browser settings.
If you have any further questions, please do not hesitate to contact the Community.
