The WiModem will always work fine in C64 mode of your C128, no matter if you cut the jumper pads or not. The issue only has to do with C128 mode, not C64 mode. It's highly unlikely that cutting the other jumpers will fix your issue, but one is located just to the right of the one you cut and the other is on the backside of the WiModem at about the same location. It's more likely that the USER port is being checked inadvertently and that is the cause of the crash. This occurs with a few programs that won't run with anything changing the USER port lines.
