I have ans arris 6190. It has been a stable connection for over a year. Started having issues 3 weeks ago. Internet connection would just die. I have replaced the first splitter outside the house with a new one from a comcast self install kit. It is the only split for the modem and has not helped. Today I can only lock 2 upstream channels. SNR is usally good. Any ideas?
Can't see your pics. Since you are a new poster, they likely need to be approved by a Forum Admin. Or you may need to make a minimum number of posts.
You could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.
