Anyone know if there is a way to set static ip's / reserved addresses on the Huawei B315? I can't see how. I set static ip's on all my devices, then the B315 goes and allocates one of those to some new random wi-fi device that connects, then my fixed device that has that same address can't get internet. I have to reboot the thing all the time. I've tried using another router (ASUS n17u) to handle the LAN with the Huawei B315 going in through the Asus's Wan port, but this noticeably slows down WAN traffic. The Huawei has a rain sim and is otherwise nice and fast. I have 4 pc's (wired) and 2 phones (wireless) on my LAN usually.
This is where it SHOULD be:
