I just installed a new i5-4690k and a gigabyte z97 gaming 5 motherboard (rev. 1.0). It comes with Killer Ethernet 2200, but so far my wifi speed is much worse than before I upgraded, and I'm pretty sure it's the software, but when ever I try to disable or uninstall the Killer Ethernet driver it just says no connection at all. Is there some sort of Microsoft or third party driver to use as an alternative that isn't a network manager? Thanks
