Steam frozen updating
Steam also use an algorithm to compress the downloaded data, which then needs to be uncompressed locally.
Be sure that when steam stop downloading, nothing else is going on (no cpu activity, no hard drive activity) - in short, be certain that the problem is your network.
I've reinstalled Steam, done the "steam://flushconfig" trick, disabled any programs that would have interferred with Steam, reset my router, and some other possible solutions but nothing has worked.
If this was not the best place to ask, then I apologize, I'm just very confused on what is going on. I had this problem, turned out I was low on disk space on that drive, but it wouldn't tell me.
Downloads: once there, click to the CLEAR DOWNLOAD CACHE button.
