Charter Communications DHCP Issues - St. Louis, MO ?

Anyone know anything about Charter Communications? Seems they just did alot of network upgrades in the St. Louis, MO area and are seeing an interesting issue.

When I use USB from their modem, I get a DHCP IP address 192.168.100.x temporarily, then a real IP address.

When I use Ethernet from their modem, I cannot get a DHCP address at all.

When I unplug the coax from the modem, I get a DHCP address

192.168.100.x but, of course, no real IP address.

Anyone have any input?

Any time you change the NIC that is directly connected to the modem, you must power cycle the modem (leave it unpowered for 15 seconds) to clear the MAC address table and allow connection to a new directly connected MAC address. Q
