:This was first noticed about 4 weeks ago running speedtests. The download tests would be fairly good but the upload tests would hang-up, spike and have very low speeds. We are talking 10 to 100 kbps at times. This issue is sporadic. If I notice delays while on the internet I usually get these results. The upload side was always rock solid until about 4 weeks ago.
I have the same problem except mine isn't sporadic, started about 5 days ago, and my upload speed can't get much past 10 kbps. At one point in my 2 hour call with Embarq tech support yesterday the tech told me that "upload speed isn't guaranteed". Isn't it a little unacceptable to expect people to get by on 10 kbps upload or less? Embarq is absolutely baffled in my case as everything looks fine from their end to my modem as they tell me. I have slowness on loading pages, although pure downloading is pretty much near normal speed. Uploading is impossible...I spoke with a supervisor who had me try a tracert and the numbers looked fine on that as well. She basically told me that she didn't know if she could pass my ticket up any higher because she didn't know what else could be done.
