Re: [Cable] Connection grinds to a halt when uploading...
According to your speed tests, you *are* coming close to maxing out your upload. You're only getting .39 mbits to start in the first test, and dropping to .13 mbits when uploading at 10KB/s-20KB/s.
Which explains your upload being killed. Your acknowledgements are getting starved out due to the little remaining upstream bandwidth, for some unknown reason.
I might have suggested disconnecting any other devices from the router, because I once had a system infected with malware that choked an entire LAN as long as it was connected to the router. But since you say you've been getting the same speeds directly connected to the modem, that couldn't be a factor.
As brad said, there's definitely something else wrong then. Which is strange, because your modem stats look good.
