Helios 300/A715-72G wifi slowdowns

Ghostyne

Hiyo - bought a new Helios 300 just prior to the holidays but have been experiencing some frustrating performance issues and am wondering if I need to RMA.  My baseline of comparison is two other Acer laptops (both Aspire type, one is 5 years old, one is 2.5 years old) that are used routinely in the same exact locations in the house, and experience none of the below symptoms.

Here are the symptoms I'm experiencing:

Slow connection speeds, both up and down, resulting in slow and failed downloads:  

• Speedtest is fairly consistent at ~20mb+ download across 5 tests, upload is around 15mb up, with one at 20, three in the 10-12 range, and one at 0.3mb. 
• one test failed with a "A socket error occurred during the download test. A firewall could be blocking the connection or the server might be having some issues." 
• the system seems to bottleneck or reset the network connection entirely every few minutes
• downloads tend to occur at roughly 2.5mb/sec regardless of site/service, but over a few minutes will throttle down, go to 0, then go up and waffle between 0.3-1.5mb/sec then back to 0; this results in lost connections and failed downloads
  
• example: entirely unable to download ffxiv from the normal downloader and had to find and download xivlauncher to do so. It avoids the Explorer browser extensions the normal downloader apparently uses)
  

Chrome performance is exceedingly slow

• it can take upwards of a minute to open almost any webpage
• I haven't tried other browsers yet, but chrome does not have this issue anywhere else across mobile, desktop, or the other two laptops
• example: twitch streams have to be reloaded about every 10 minutes and will NOT stay up. Error message: Your browser encountered an error while decoding the video. (Error #3000); I've made sure Chrome is updated, enabled cookies, cleared caches, disabled all plugins to no avail

Steps taken so far:

• uninstalled Norton
• uninstalled the default Killer wifi software
• uninstalled the default Killer Performance Suite
• downloaded/installed the updated Killer wifi-6 version released 9/27/21
• downloaded/installed Killer Performance Suite
• I've tried disabling Defender and had no firewall running (this is absolutely not my preference) and still experience the resets

Any help would be appreciated.

@Ghostyne did you try to factory reset Windows ?

Hi @Ghostyne,

How many devices connected to the same wifi network ?

Leostat

And what frequecy wifi are you using ?

After two days of troubleshooting, ruled out frequency/band type/interference, or anything to do with the network.  Identified the issue as nonstop 5005 and 5007 event errors by the Killer Wifi 1650i setup. Worked with an Acer support tech directly to try multiple drivers, then a factory reset, and retried drivers again. No joy. The options are to mail it in or get a refund.  I'm opting for the latter.  Thanks for the responses though.
