Yep... Better to download drivers only, without that manager. Manager do what it is made for... But example I download games from steam and it show that max dl speed was under 800 KB/S when without manager it show that it downloaded sometimes on 1 MB/S so... They should add those manual drivers to their driver list... BTW I talk about Killer Ethernet e220x

Uninstalling Killer Network Manager will also uninstall the drivers for your network card and in my case, windows 8 doesn't have any drivers for it. I suppose you could install it, make a driver backup with drivermax, uninstall it, and then restore just the network driver from the driver backup. I'm curious as to what the "Bandwidth Control" feature does. It tests your connection speed upon installing the program, this is for bandwidth control. So what if my connection speed increases? Will Killer Network Manager hold me back?

If you want to keep this, but not have it run go to run > msconfig > startup > uncheck this to startup on windows boot... It makes it so it isn't running unless you manually click it to run.

When I uninstall, I can't get wi-fi. Yet it pops on screen at startup and won't go away. Thanks
