Good day,
From here, you neeed to sign up with Afrihost on the website, and say you have an existing fiber install.
Then, you need to connect your router to your GPON (The box VUMA installed), and connect up a PC to the router
Then login to your Afrihost ClientZone, and you will be prompted for a OBJECT NUMBER. Find this by opening up a web page on the PC conneted to your router, in the "My Account" section of the default VUMA page, is a section with your object number.
Put this number into your ClientZone, and Afrihost will begin to provision your service.
After around 5-10 minutes, reboot the router, and then open a new web-page, and you will be redirected to an AFrihost login page. Here, log-in with your Afrihost ClientZone credentials. Afrihost will then provision your service, and you should be able to browse right away!
