I have cable modem epc3925 that stocks on reject(c)
and also i have epc3208 that goes online

can anyone help me please?

possible cert file update needed

thinking with it being an older modem model, the cert file may have expired or needs a re-cert added to the modem file
setting the clock back a few years make a difference?
Just a thought

hello dear,

hello dear,
I appreciate your time and your answer,
I have tried to change the clock but it didn't worked.
I'm not a big engineer on docsis thing. Can you probably give me some hints how to check the certificate?
