Pulled 11GB zip file from another machine to the XPS (x-fer rate seemed to average around 6MB/s) Ran what seemed like 30 or more Speedtest runs with no issues (and very high speeds – many +200Mbps)Ĭonnected to my other laptops and began internal network testing Uninstalled “new” Killer Wireless driver ( so it reverted to the original driver – Atheros Communications 4.0.2.217 circa )

Had significant issues just trying to get the card to recognize a Wi-Fi networkĪfter a few minutes, it brought down our network (whole house). Upon installation, card was immediately rendered inoperative Installed Killer Wireless “new” driver as this was the original intent Noticed the Wi-Fi card seemed to work, ran some Speedtest runs and it was indeed working very well (over 100Mbps) Removed the prior installed Killer Wireless driver and rebooted as instructed upon completion I was set to return the XPS to Best Buy but saw this article and here's what follows:ĭownloaded Killer Wireless driver latest driver aboveīegan installation which instructed I must remove the existing Killer Wireless driver Ran a series of tests with this and my SP2 and the latter averaged 110Mbps, the XPS averaged 39Mbps and still took down the router albeit at a much less frequent basis. Insstalled the latest AC1750v2 drivers and the problem seemed to be limited to a drops and reconnects but woefully slow x-fer rates. First attempt to do a run and it brought down the router. I called Dell and they had me install their driver suite. I had a network 'corruption' almost immediately (within an hour) where it took down my network (forcing a hard boot of my AC1750v2).

Hey cardosofill, I just got my XPS 15 9560 six days ago.
