Hello.
Sending "land" packet to motorola device, will cause it to crash.
"LanD" packet is simple TCP syn packet:
Source IP = 192.168.100.1
Destanation IP = 192.168.100.1
Source Port = 80
Destanation Port =80
SYN Flag= 1
One packet can crash modem and all network on cable part will be
unreacheble.
Only physical restart can help.
May be other models are vulnerable.
Alexey Sintsov.
