Re: Constant disconnects

I have nothing more to add except I am having the same issues. Now I can't even manage to get into contact with "support"!

Re: Constant disconnects

Thanks for the reply.... I just lost internet again... reboot fixed it. Sad part is the modem had only been up for 36 hours.

Internet is out again, called Comcast... Modem is showing normal lights... The interesting part is can not do a remote reset, I'm not going to do anything until I get a call back.

Re: Constant disconnects

Well far months for tech support calls i final plaied the only card I had left. Cancelation.... It works spoke with an agnet and agreed to swap to a comcast modem.... the issue persisted so they had no other option remaining so a tech was sent out. Tech chekced the lines and said the signal was fine, I disagreed so he call in to double check and I WAS RIGHT. The network tech told him that a negative signal (power) at the tap is not acceptable for a docsis 3.1 modem. They has network tech come out later that day to fix the issue. Now all of my signal levels at are above +5dBmv and SNR of 37-38dB.  Its sad that I had to threaten to cancel but I have found that seem to be the only way to get Comcast to listen.
