I've been having some whacky problems lately with our connection in dfw.
We've had to power cycle the SB4100 to get service back at least once a day.
I noticed in the "log" that they had been loading SB4100-1.4.9.4-SCM02-NOSH firmware into the modem lately but today they have reverted to the SB4100-1.4.9.0-SCM00-NOSH version (again after a strange outage and a power cycle of the modem service is restored).
Looks like some bad firmware got out.
