It's been doing it for a long time, my steam doesn't want to download games for shit. I have really good internet and steam is liek nopnnonpnopnopn.
I try to download something and it constantly pauses and just stops downloading all together for minutes at a time, then it starts again for like 10seconds at 4Mb/s+ downloads speed and then just stops again. Takes 2hours to download a 100mb update, I've changed download region and such, pretty much tried everything.
Seriously my Csgo has a 2.5GB update and it's been at 98% for 20 minutes now... really pissing me off. steam is more of a troll than anything.
