I've had experience with these, I ended up taking it back, had similar issues. Got a Netcomm equivalent and the problems all went away, and it supports everything on the market currently for Voda / 2degrees / XT, and has done-so for the last 3-odd years!
Pretty sure this is mine:
NetComm N3G005W

It's an older model though (As mentioned it's been solid for AGES), and newer Netcomm ones cost less![]()
