Hi.
I've recently purchased a Linksys USB WiFi N600 adapter for my new PC that doesn't have a built-in adapter.
This wouldn't be so bad, if the connection wasn't slow with lost packets on even 4/5 bars connection.
I've used PingPlotter to show this: REMOVED IMAGE
I don't know what is causing this, and I cannot play any games on my PC until I fix this.
(Unless I want to wait days for them to download.)
Some things that might help:
Other PCs in the household don't seem to have this problem.
Plugging it into Ethernet is not an option.
Before I got the adapter, I've tried to use Windows Internet Connection Sharing (Which messed up my laptop as the host and I had to refresh it's files. 🙁 )
Before the adapter I've also successfully tethered the PC with a tablet which gave me internet of about the same speed.
Somehow, unplugging a printer that was in a USB port boosted my internet speed for a few seconds. Same with moving the tower around a little bit.
Doing a file refresh on this PC as well is my LAST resort, I've finally just got it set up.
That's all I really know.
Thank you for reading, and I really hope we can find a solution. I'm sick of this and I really want to just use my new computer. 
EDIT: I've bought a new adapter, this one has a longer reach and it's bigger. It seems to have fixed my problem, even though the other adapter claimed to do the same as this one. Maybe the last one was faulty? Either way, my problem is solved! Thanks for helping.
