I have had my device just over a week now and am having all sorts of trouble getting it to function.  I called for help and the technician talked me through getting on line using 192.168.0.254.  It worked briefly but then the Comcast modem crashed and had to be reset. Ever since my booster doesn't boost; in fact it drains.

So I have been trying to get back to 192.168.0.254 to reconfigure the system like it was before (or even better since the 5 GHz didn't activate) and my computer won't link up again.  Help.  What can I do?
