How do I fix the issue with my Killer Wireless Network Adaptor that keeps disconnecting? G9-591

Hi Antsmasher

did you try to install driver from ace support ? https://www.acer.com/ac/en/IN/content/support-product/6370?b=1

also did you update the bios version ?

if it working and stops, I think it's driver version. If you have the killer wireless software program installed, try to uninstall it.

Thanks for the suggestions, Batareika007.

The device manager doesn't allows the option to roll back the wireless adapter driver. The button is grayed out.

I tried changing the power settings as you have pointed out, but after awhile, the wireless adapter still disconnected.

I am going to download the driver from Acer's support page.

I am assuming the one I have to download is the Wireless Land Driver, correct?

I just want to confirm with you before I move on ahead.

There are usually 2 LAN drivers (LAN is "Local Area Network" which is usually the network inside your main router; think of it like a gated community, the router is the gatekeeper and weak security guard; over wireless, you put your messages in the mail drone and they fly away to the gate, then are redirected to one of those old suction pipes to get sent; over wire, you have your own suction pipe).
There could be any number of reasons your machine is constantly disconnecting.  One is the power options.  Not USB mind you... ...You want to go to PCI in those options and tell it not to turn stuff off.  The problem with these acer boards is that they tend to drain a lot of battery power, so anything that adds too much load, during any kind of a spike (from your power adapter or the battery), the system will default to turning things off to protect the more sensitive parts that it can do without, lightening the load, while it shunts the rest of the spike back to it's ground-path (usually to the battery).  Unfortunately, it's really sensitive, and most of the wireless cards are already set up with their own ground-path protection.  This is a holdover in windows, they've had it since early PCI, back when a good spike could really fry a motherboard, a graphics card, a wireless card, anything you added on really.
Next, you'll want to right click the little windows icon in the bottom left corner and go to device manager.  You should see an item called "Network Adapters".  Open that.  Now you should see every adapter, physical or software (I have about a dozen WAN miniport hubs for different apps; windows 10 pro for workstations...), and you can select which driver you want to connect to.  I have 2 that have KILLER in the name.  One is my ethernet, the other my wireless.  The reason they did this is to enable a tech called "Doubleshot", which will test your connections for the best speeds and pick which one is best with each up\download when you have both connected  (It probably arrived in the software a good deal after your hardware was built).  Right click the first one, go to "Properties", then find the tab that says "Power Management".  Uncheck the box that lets it turn off the device.  Repeat this for the rest of the devices with KILLER in the name.  This will prevent windows from turning off your network hardware under any circumstances.  Restart your pc and try your networking.  If this doesn't fix your problem, you'll need to update the Killer networking suite to the latest version.  You can look it up online.  Once you download the installer, don't open it.  Move it to your desktop from your downloads folder.  Leave it there.  Now go to control panels (yes it's old, but it's still the best); you can find it by using the search next to the Windows icon (unless you've moved things all around).  Type in Control Panel, and it should have a suggestion for you; open that, and then, in the top text area where you see the words "Control Panel", put the mouse on the right side of the words until an arrow shows up, left click the arrow, select "All control panel" (Or similar), and then find "Programs and Features", open that.  Find Killer Networking or Killer wireless in your list there, and select it, then go to where it says "Uninstall".  When that's finished, restart.  Once you finish with that, try your networking for a while, without the manager (millions get by without it).  See how you like that.  IF you're a curious type who likes to fiddle with something that's already working, install the new Killer Networking Suite, but don't actually make any changes, just use it to monitor things unless you really know your hardware.  Try it out, and see how it goes.
