It seems that with Vodacom fibre Google services (YouTube and Drive are what I mainly use) download speeds are capped at 1-4Mbps. Most other services I use download at reasonable speeds. I mitigate this by using a VPN (Express VPN), but that has its drawbacks in terms of ping and having to fill...
I am experiencing the exact same thing with @Cell_C through Afrihost fixed wireless (@AfriFella). Can barely use Netflix, Youtube, Showmax and such, but my download speeds for any other service such as Steam or Google Drive is fine.
Super annoying and Afrihost's client service doens't know how...
