Has anyone had their Intel 62xx WiFi card replaced with a Killer 1202? Dell have now switched from using the Intels to the Killer cards, that must be for a reason.
I originally had an Intel one that got replaced with a Killer card. The performance increase was notable but a few weeks later got worse again.
A couple of days ago I received a replacement XPS13 and it had a Killer card. I occasionally had wifi problems until today when I uninstalled network manager and installed Wicd. My issue wasn't that internet was slow, just that if I was more than a metre away from the router the signal would drop dramatically (of course resulting in speed decrease). With Wicd this doesn't happen anymore
