Yes, this blooper of mine was explained to me earlier, but I didn’t think of that 700kb/s being high enough to fully block my connection. With my new router I’ve been able to download games ~3 times quicker than with the old using only the wired connection. I’ll need to tweak that setting again.
I don’t usually have any other programs than Discord and Firefox, for guides & googling game stuff, active when I’m playing.
My PC is quite old and built by a good friend and bad connection has taught me to be sparse and to kill any auto updaters windows and other programs have.
Yes, the wired was left alive due to it usually having less lag and jitter. Useful when playing Team PvP games like WoT and WoWS (I’m too old for twitch shooters 
)
The HDD might be an issue, I have 2. A ~230GB SSD with my OS and some other stuff and a gifted(formatted just in case) ~465GB HDD. AoC is due to space issues located on the HDD(50%+ free space atm).
