Over 9 technicians have come out to tell me they don't know what the problem is. I recently was told that I had to swap to their modem before they would troubleshoot any farther. Once that was complete, my line was replaced from the house to the neighborhood node. The problem is still persistent. This is just something we have to live with by using Cox apparently. Unacceptable... Re: Download speed fine. Poor/intermittent upload speed. I have been keeping a log with screenshots, dates, and times every time I realize it goes out. Which is probably the only reason they offered to change the line. Century Link doesn't offer anything close to what I require. Re: Download speed fine. Poor/intermittent upload speed.
