For the past couple of days I've been having problems uploading things. I went to speedtest.com yesterday and download speed was normal but when it tried to do the upload speed test it just sat on "connecting" and didn't even complete it. I can sometimes upload things, sometimes not, and it's very slow. For instance, when I try to upload a photo on my phone to Instagram, on out wireless network it sits there forever then fails. But on 3G it uploads very quickly. Does this sound like a problem with my networking equipment, or something on Comcast's end? Any input would be appreciated.
FYI this has been going on for 7+ days.
