@cavedog when you used the huawei b618 with your fibre, did the lan light blink constantly?
switching back to the huawei b618 as the zyxel just wont let me use my smart dns properly. fast router but not everything functions properly.
Yes it will blink constantly even if you use no data. That blinking means an active internet connection.
If you have a B618 supplied by Rain it should have build in voip and vpn also enabled.
I tried to ask their WhatsApp support if MTN is planning on increasing their max line speed from 100mb and they responded simply telling me I can get 100mb - clearly not even reading my question properly.. can't say I expected any better but it is disappointing
