Hi all. The ready light went out on my NTL cable modem (Ambit 200), and occasionally kept flashing for the first few seconds after I powered the modem off, removed all the cables and rebooted it, then the RDY went out completely. And in this occasion I could only obtain 192.168 IP address with no DNS. The sync light is fine. Never got 169.xxx IP so I guess it is not my laptopââ‚Ã⠀šÃ‚¬ÃƒÂ¢Ã¢â‚¬Å¾Ã‚¢s issue. This problem has been happening since about half a month ago, and Iâ₠¬ÃƒÆ’¢â€žÂ¢ve also checked the status of my SACM. Here are the statistics:

Downstream Status

Downstream Lock : Locked

Downstream Frequency : 402750000 Hz

Downstream Modulation : QAM64

Downstream Interleave Depth : 32

Downstream Receive Power Level : 0.3 dBmV

Downstream SNR : 33.8 dB



Upstream Status

Upstream Channel ID : 3

Upstream Transmit Power Level : 50.0 dBmV

Upstream Symbol Rate : 2560 Ksym/sec

Upstream Frequency : 28800000 Hz

Upstream Mini-Slot Size : 2



Some event logs show as following:

SYNC Timing Synchronization failure - Loss of Sync

Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 timeout

No Ranging Response received - T3 time-out



And here are some details about my laptop: windows xp+sp2, no firewall running, no router in use.



Could anyone here give some ideas?

Many thanks.
