Ambit 256 Rebooting / Only 250kbps

[ronvegas]

Hi,

My Ambit 256 with Hax 39 has just stopped working, goes online, then reboots every 10 seconds. I know the MAC is good, works perfect on my Motorola 5100. Tried 30 other MACS either keeps rebooting OR 2 of the MACS stay online OK but only give 250kbps throughput?

Any ideas whats going on with the 256, read something about a Docsis issue but dont know what to do or have anything to fix it etc.

Thanks
