Assuming you are on ADSL or VDSL ( FTTC ) , these systems can be susceptible to REIN and SHINE ( search the terms if required ) but basically it’s interference from ‘faulty’ electrical devices, things like cheap Chinese Christmas tree lights , central heating pumps , dodgy fluorescent lights etc., these things can , when switching off and on emit ‘interference’ that can causes ADSL / VDSL to lose sync , this means that the broadband service has to reconnect, giving a break in service ( your hub flashing orange) there was a famous example where someone with an old TV knocked out an entire village’s broadband every time that TV was switched on…..if it’s clear when you use this charger your broadband ‘fails’ , get a different charger.
