Same here feb up with this doing ping and tracert shows connection full bars but no connection on my phone or pcIm having the same problem. Im on a b525 100g mtn afrihost bundle. Was working fine until yesterday afternoon. Shows blue light and router home page says 4g lte 4bars active but no internet.
Edit: and to add to that, i can ping any external ip such as google or a game server in EU with no problem. But trying to connect to a website it is stuck at Peeforming TLS handshake
Edit2: It is working now. Sent support a ticket. I dont know if they did something or if it was me. Last thing I did was to Select manual network in router options and selected 4G MTN. Hope this helps other people with same problem.
Edit3: off again.. giving up for today. Loadshedding in half an hour anyway. You win south africa
