SB5101 not working

[laythy]

hi there
im new to all this so i might not know much but i kinda know a bit about what im doing

a friend of mine gave me his modem that worked fine at his house but its not working at mine

i tried another one that worked at his house too but still not working on mine

we live in the same area but might not be the same range so this might be the problem

we both have comcast and using DNS 208.67.222.222, 208.67.220.220

i am using a mac but i can get access to a pc if i need to

the modem is flashed with Haxorware Version 1.1 Revision 38

checked boxes in setting are
Disable Firmware Upgrades
Force Network Access
DHCP Server

Frequency settings
597000000
549000000
339000000
chan 4

using d11_m_sb5101_showcase_c05.cm file
BPI+DOCSIS1.1 tried to bypass still didnt work

here is a log file
