Very slow upload speeds, download speeds are fine
The past couple months, I have been having very slow upload speeds (anywhere between 100 Kbps to 2 Mbps) that are intermittent. There doesn't seem to be any specific time that these occur. When this is happening, my download speed stays high. I am currently paying for 100 Mbps download and 10 Mbps upload.
I have had two contractors out to my apartment in the past week. The first one informed me that the signal my unit is receiving is actually really strong. The second one took out the splitter that my unit was going into to see if that would eliminate the problem, but it has not. Unfortunately, since the problems only occurs somewhat randomly, it was not occurring when they were at my place.
On my end, I have tried multiple modems, multiple coax cables from the wall to my modem, and multiple ethernet cables from the modem to my computer (I am usually directly connected to my modem). I have hooked up my wireless router to verify that I was also receiving poor upload speeds on my wireless network, just to ensure that it wasn't my computer's network card causing issues. After doing all these things and still seeing the issue, I do not believe it is on my end.
My modem is an Arris SB6183. Here are the statistics for downstream/upstream:
I am noticing many critical events in the modem logs, but am unsure what they really mean. I can post them if necessary.
I just installed PingPlotter and was doing a quick test, I noticed that I'm dropping about ~25% of my packets when the upload speed problem is ongoing.
Can I please get some assistance with this? I don't really want to continue having contractors coming out to my place as nothing is really changing. I have gone back and forth with the Twitter support, who have also noticed some issues. Please let me know if you require any more information.
