CM400 High Speed DOCSIS 3.0 Cable Modem(CM400)
I have a pressing issue that i cannot figure out what is going on. Here is the Modems info - CM400 High Speed DOCSIS 3.0 Cable Modem(CM400). I have used this modem for a few years on Spectrums Netwo...
I would contact Spectrum to see if there was any kind of FW they put on this modem that would lock the modem to be used only to there ISP service. You may need to take it to a spectrum office to have someone look at it. ISP usually don't lock out user owned modems. I have heard odd things though with spectrum.
Has a factory reset been performed on the modem. Press the reset button for 15 seconds then release.
Mfrs only warrenty items for a certain time frame. Been like this for a while now. Though there are the forums. Hopefully we can help.
Spectrum denies performing/installing any firmware that would restrict the modem to be used on another ISP. Yea did a full reset and nothing changes.
Sad that netgear support cannot get involved in this. Greedy
