Cable connection drops, high uncorrectables, slow Internet speeds and webpage loads
I just upgraded to Cox's 100 Preferred tier last month, and now my Internet connection would disconnect on its own. I had a Cox contractor came out to my house in February 2017, and he fixed the issue by removing something in the junction box, but now the disconnects, slow webpage loads, slow Internet speeds, and high uncorrectables have returned with a vengeance. I'm using a SB6141 which I had in my possession since 2014. These problems are getting really annoying. I have even tried rebooting my cable modem and router, but those have done no good. I don't want to spend money on a new cable modem and still face the same problems I am experiencing now.
