SA 2434 Docsis 2.0 modem w/sip

It's a nice modem. Wireless, 4 port ethernet for home networking and two phone jacks.
Problem is it doesn't stay online. finds downstream, locks on upstream does the dhcp, gets a basic or bpi file (tried bare bone and bpi, bpi+). goes online and few minutes later it goes offline and starts all over again. Haven't done a capture yet. tried to log into the modem to get the log files, but doesn't stay on long enough, also search for docs on the modems point me to Cisco, but searches there only give me info for routers and switches, not cable modems.
so if anyone has one of these, please let me know. there's only one mac address so I don't think it's looking for another file.
Have a great weekend

2434 problems

Hi Carl,

i recently found your post regarding SA 2434

I have the same strange problem:
-SA/Webstar 2434 is working fine behind Motorola BSR1000.
-it wont stay online behind CISCO UBR7246VXR,Identical scenario, same RF, same signals, same wiring
-behind the CISCO on same tap there are other modems Motorola,Arris,SA2203,THomson... all working except 2434

please respond if you have found any resolution to this problem

solved

For anyone having this problem, I have fixed it:

You have to add option mtaopt122 to your dhcp config file for this modem to stay online.
Example:
option mtaopt123 01:04:aa:bb:cc:dd;

Where aa bb cc dd are hex representation of the decimal ip address of the tftp server
