We all know how sky colours determine the next day’s weather “Red sky at night, shepherd’s delight. Red sky in the morning, shepherd’s warning”. Well, we need something similar for JUMP modems, e.g. “Blue light on JUMP, tutor’s pump. Red light on JUMP, tutor’s hump.” In other words, if the Network Mode light next to the white ‘on/off’ light stays red when the modem is powered up (it should change to blue), this means the modem is faulty and I don’t think there is anything you can do about it (apart from reporting this to Skinny, and they will send you a courier bag to send it for repair or recycling). The photo below is what modems should look like within 20-30 seconds of being powered up.
