Hi guys can someone please help me understand this, I bought an inverter. It runs all the things I need. Anyways load shedding hits and everything works fine but after 20 minutes my fibre internet stops working, the csp and modem still has power but the internet light on my modem goes red and I don’t have internet. I don’t understand how to correct this, is it my isp?is it vuma? Please assist if possible thanks !
