    I happen to have a family of three Dell machines in the house - a new arrival XPS 9360, an old beast Precision M4800 and an "aspiring" Inspirion 5667.

    The new XPS 9360 is equipped with the Killer 1535 wifi card while the old models came with Intel cards. I've run tens of speed tests and it's certain for me that the Killer card's performance is constantly 20-25% lower than those of Intel's cards (all cards with the newest drivers available).

    Has anyone done similar tests or come across Killer performance issues? There are lots of similar threads on Killer cards, and they are generally not really appreciated, but I'm seeking their comparison vs. Intel cards.

    Well, Intel always worked out of box with no tweaks and Killer always needed tweaks.Wireless Performance was similar for me.

    Yeah, my impressions are the same... Would you be keen enough to share the Killer tweaks you find necessary to apply?

    1. Download the newer Killer SW drivers
    2. Goto Device Manager -> Network Adapters -> killer 1535 -> properties
    3. In properties window, Select Advanced Tab > Set Roaming Aggressiveness to Lowest. Optionally set the channel preference too., if needed.

    Many thanks for this, Vasduev! I really appreciate it!

    Some questions though, if you don't mind:
    1. You're saying to prefer the latest OEM drivers over Dell approved drivers (which are indeed older), right?
    2. I'm bit surprised with the Roaming Aggressiveness, as I've just increased it to High-Medium :) Can you explain why lower is better here?
    3. I can't find any place to tweak channel, which is a great surprise for me... It's not in the device properities (as for e.g. Intel) and it's not in the Killer Network Manager, either. I haven't tried the new Killer Suite, maybe it's there? Can you point me to the right place?

    Yes download from Killer directly they're updating every month with constant bug fixes.
    Actually @judal57 was testing these parameters, he told me this when I asked how to prevent random disconnect plaguing Killer WLAN/BT.
    For tweaking channel, its better to do it in a router by using Wifi Analyser app.

    OK, I've played a bit with my killing Killer ;) and here are the effects:
    1. installed the latest drivers from the Killer's website - alone it hasn't improved my situation a bit,
    2. changed the card mode into b/g/n, as those are standards served by a modem provided by my ISP - this gave me a significant speed boost,
    3. tried different values of Roaming Aggressiveness - it looks the "medium-low" works best in my case- this gave me only a few percent improvement but still...
    Overall, I'm at the same level now that the Intel cards in my other machines can provide, which is great!

    One question remains, though - is there any way to adjust the channel in the card itself? I've already tweaked it for best performance of my other hardware, so I'd like to stick to the current one.

    I have Killer 1535 in my Alienware 17 R4, Killer 1535/Intel 8260 In the P870DM-G and Intel 8265 in P870DM3-G.

    The Killer performs best with my Mikrotik Router at home, but sub par with my ASUS router. The Intel 8260 performs best with my ASUS Router and kinda okish with my Mikrotik router. 8265 is pretty decent with my Mikrotik but amazing with the ASUS.
    At work, the Killer 1535 works amazing, im not sure what routers/access points we are using. The Intel 8260 is pretty decent here as well. 8265 for some reason ****s the bed at work though.

    So point being, Routers will matter way more than the card it self.

    As for the drivers for the Killer 1535, im using the stock Windows Update drivers.

    @mikolajek Channels are set on the router, if that's what you mean by adjusting the channel.

    It isnt talked about a lot of times, but changing to a particular channel from Automatic, helps a great deal a lot of times.
