Will The Killer Wireless-AC 1550 Work In My Laptop?


Will The Killer Wireless-AC 1550 Work In My Laptop?

Many users have emailed us asking if the Killer Wireless-AC 1550 will fit in their laptop. (Click here to find out if the 1550 will fit your desktop.) Although we cannot know the exact specifications of each make and model of laptop, even if we have the model numbers for said laptops, we can give you some basic guidelines.

Look Up The Wireless Adapter That Your Machine Is Currently Using To See If It Uses A PCIe Half Mini Adapter, or An M.2 Adapter

To do this, right-click Start, click Device Manager, then double-click Network Adapters. You should find a wireless adapter listed there. Comparing to that adapter is the easiest way to know what will work in your system.

The Killer Wireless-AC 1550 is an M.2 adapter which uses IPEX-MHF4 antenna receptacles.

If your machine is using a Killer Wireless-AC 1525, 1435, or 1535, then the 1550 will almost certainly work as a replacement/upgrade. Please see manufacturer caveats below. 

If your machine is using a Killer Wireless-N 1102, 1103, or 1202, it will definitely not work as a replacement/upgrade, as these are PCIe Half Mini adapters. 

If your machine is using another brand's wireless adapter, you will need to find out if that adapter is an M.2 adapter that uses IPEX-MHF4 antenna receptacles. If it is not an M.2 adapter, then the 1550 will not work in its place. If the antennas are different, then the antenna leads will not fit onto the 1550 without modification, which may include cutting and splicing wires.Official websites are good sources of information, but you can also find information on shopping websites, such as Amazon and eBay, as resellers have a vested interest in providing accurate information about the product they are selling. Just make sure to verify with a few listings. For 100% verification, you will need to contact the machine manufacturer to find out what interface and antenna conections it uses for Wi-Fi. 

You can also open the machine up to verify whether the machine uses an M.2 slot for its Wi-Fi adapters. Below is an image comparing a PCIe Half Mini and an M.2 adapter, the two most common formats with modern Wi-Fi adapters.:

Manufacturer Caveats

There are two other things that need to be verified before you know for sure if switching Wi-Fi adapters is an option. Only the machine manufacturer or, potentially, their support community, can tell you these things.

  • Does the machine employ Wi-Fi lockouts? Some machine manufacturers have lockouts, which are built into the BIOS, that will either prevent the machine from booting, or prevent the wireless adapter from working, if an adapter other than the original is used. 
  • Is the Wi-Fi adapter soldered in? Some machine manufacturers solder down the Wi-Fi adapter. In these machines, even though they are using a normal slot for the Wi-Fi adapter, the adapter cannot be removed.

Other Considerations

  • Linux Support - The Killer Wireless-AC 1550 uses the iwlwifi driver, which is widely supported in nearly every Linux distribution. However, only the latest versions of this driver contain the hardware ID for the 1550, so only the latest Linux kernels support the 1550. Without the advanced Linux expertise required to patch the driver and rebuild the kernel, Linux support is still limited. 
  • Windows Support - The Killer Wireless-AC 1550 is not supported in Windows 7 or Windows 8.1. It is only supported in Windows 10. The Wireless xTend feature is only supported in Windows 10 1803 (April 2018 Update). 

Internet Problems With New Computers


Internet Problems With New Computers

This article only applies to brand new computers using Windows 10.

Some users may experience issues with brand new computers with Killer Network adapters and the Killer Control Center or Killer Network Manager preinstalled. 

These issues are often caused by Windows automatically updating to the latest version of the operating system without giving the user the chance to update any preinstalled software or device drivers. This results in software, which was likely up to date at the time the machine was boxed by the manufacturer, running on a version of the operating system on which it was never tested, and may not be able to operate on correctly.

If the user notices that, after Windows has updated, their Internet performance is severely degraded, or they see bluescreen errors that are attributed to our software or drivers, they should uninstall the Killer Control Center or Killer Network Manager, make sure Windows is fully updated, and then install the latest version of the Killer Control Center

Here is the step-by-step:

  1. If you are using Windows 10 and don't already know which build, find out which build of Windows that your machine is currently running. If your computer has completed the Windows 10 Spring 2018 update, you are running version 1803. Otherwise, or if you don't know, continue reading.
    1. Click Start
    2. Type winver and press Enter
    3. A box will appear with some information about Windows. There will be a 'Version" number. It will probably be either 1709 or 1803. 
  2. Download the correct installer for your version of Windows.
    1. Windows 7, Windows 8.1, and Windows 10 Version 1709 and below, or those using a Wireless-N device, should download this installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
    2. Thos using Windows 10 Version 1803 and above should, and not using a Wireless-N adapter, should download this installer - https://www.killernetworking.com/driver-downloads/item/kcc-uwd
  3. Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe
  4. Restart your machine by clicking Start > Power > Restart
  5. Run the Killer Software Uninstaller Tool. It is not necessary to scan, and the scan may not find anything. Regardless, click Remove Killer Software, and give it some time to run. When it is finished, it will say "RESTART REQUIRED."
  6. Restart your machine by clicking Start > Power > Restart
  7. Once your machine has booted back up, access  your temporary files folder and delete the contents
    1. Click Start
    2. Type %temp% and press Enter. Your temp folder should open.
    3. Delete all files in the temp folder. These are all temporary install files, and are safe to delete. If you receive a prompt saying that a file cannot be deleted, you can safely select Skip All
    4. Close the temp folder
  8. Run the installer that you downloaded for the Killer Control Center. Follow the prompts to complete the installation. 
  9. Restart your machine if the installer requested a restart.
  10. Test to see if the issue is resolved.

If you cannot install the latest Killer Control Center because you receive an error that says that the current package cannot be installed with one of our older packages, even after using this clean install guide, please see our guide for "Cannot Be Installed With" Errors.
