This might sound stupid question, but I need to know: can only my ISP update the firmware of my cable modem? Or can I do it? And if yes, should I?
I have vague memory of once updating something using my PC after AVAST gave false alert about network being compromised (it was later solved as their screw-up).
I can not remember what I updated, just tinkering in panic and updating something from PC I have no found again later.
1) So I need to know - is it possible to update modem firmware myself? And could I ruin something about modem from PC side?
My cable modem is Scientific Atlanta 2203.
2) I am not sure if I updated firmware once in past or not, but if I messed something up back then, modem would not simply work right now?
I mean, if I have done any damage to it by installing anything, it wouldn't be hiding some security risk? Like, is there any method to check if modem is working properly and not being a security risk? Connection and speed seem to be working just fine. I simply don't know enough about modems to be sure if there are no security risks.
