This problem started randomly happening around two days ago. I don't know what changed but the last time I tried to watch a stream on twitch.tv the player kept freezing even on the very lowest quality setting. Everything worked just fine on a different computer and twitch works well on my PS4 (which is wireless no less) browser and the xbox app. I also tried watching something in vimeo and it would play the video for a few seconds, skip to another video and repeat. First thing I tried was deleting my cache and cookies etc. with the program ccleaner. Second thing I tried was uninstalling and reinstalling flash player but when I try I always get "lost connection trying to reconnect" at around 40% into the download. So the next thing I tried was using a different cat5 cable, using a different port on my router (again, everything else works fine) but no luck. I've also tried downloading the flash installer from IE and Chrome After that I tried doing a clean install of flash as instructed here How do I do a clean install of Flash Player?
I've also tried doing the direct download link but it's still the same issue.

I am officially running out of things to try next. If anyone could help I would much appreciate it. I am running on Windows 7 64-bit and my browser of choice is Firefox. Need any other info, please ask.
