Received a new Efficient Speedstream 5100b modem/router as part of an SBC offering -- fired it up last night & it was working just fine. Turned off my computers, left the modem on (all lights on the modem indicated that it was well - green).
This morning I check the 5100b and find what looks to be a repeated POST (Power On Start Test); all lights off for approx. 20 seconds, then for approx. 4-5 seconds:
Power light flashes red (not steady red, but flashing red) Ethernet light steady green DSL light steady green Internet light steady green Activity light steady green
Then all lights go dead again for another 20 seconds. This occurs with or without the Ethernet and/or DSL line connected to the unit.
To ensure that it wasn't a problem with the surge protector that I had it plugged into, I disconnected the device & reconnected to a direct electrical outlet; same symptoms. Also tried resetting the device with the reset button on the bottom of the box -- no luck/change.
The DSL provider (SBC) is shipping me a new 5100b within the next few days, but even so I curious as to what might have happened. There were no recorded power surges, not electrical storms, nothing obvious that I can think of from the electrical input standpoint... I even went so far as to eliminate supplied power transformer/plug unit by testing with a good known alternate power unit -- same symptoms.
At this point I'm wondering if perhaps: 1) the unit has a bad flash/rom that failed during the night, or 2) the DSL provider (SBC) did something from their side during the night - tried to do a flash update or remote config that failed, etc., that may have caused the problem.
Has anyone ever heard of this this happening?
