Motrolla Sb5101 Comcast won't stay connected!!

[drewmerc]

Hello guys, I have a modded Sb5101 Motrolla modem yes it has haxorware, however the modem isn't working anymore, its not my area or my house I tried another modem and it worked flawlessly, however this modem is not working it never wants to connect its always limited and when it does connect sucessfully it only stays on for about 2 mins then it goes to limited. My logs in haxorware are pretty repetitive with critical errors.
