Hi! Need help with sb5101 Haxorware

[SB3]

You're premod should always be 192.168.100.1 so 192.168.100.2 as a client IP should work fine. If the webif doesn't come up you can always telnet to the modem with the username root and admin as password. You might have corrupted your nonvol, in which case you can reset it from telnet. I would try unplugging the modem and remove the coax, once rebooted and off the stream, try to access webif.
