Why speed is so slow on PC but very fast on OS?

I updated spectrum modem to 400 mbps and did a direct connection test and it usually is hovering between 300 mpbs to 425 mbps. I just purchased brand new Nighthawk X6AC3200 Tri-Band WiFi Router and did wifi analyzer and changed my channel settings in router to unused channels in my apt complex. 

I just discovered that I tested MAC laptop and iphones running at 350 mbps to 425 mbps and I tested two of my PCs. One is work PC and one is gaming PC and both are very unstable running at 10 mbps during the day and sometimes 100-150 mbps during nights.    All devices are set to 3rd band..   WHY does PC wifi run SO slow while OS devices are running great??? I am lost..

Thanks,

William

Re: Why speed is so slow on PC but very fast on OS?

What chipset is in the laptops running slow? Kind of key because different wifi chipsets have different capabilities. 

have you upgraded the driver on the laptops chipsets? windows update usually doesn't even have close to the latest driver.

Are you testing in the same room/different distance? 

Have you tried changing to the other 5ghz band? 

How are you speedtesting them? try dslreports.org

All devices are in same room within 20 feet range to wifi.  Heck, I tested work PC and Mac laptop side by side and received big different speed difference and they are connected on exactly same 3rd band.

My gaming PC (with two big antennas in the back) that I just bought last month should have all updated chips. MAC is very old and my Iphone 11 pro max is 8 months old. My work PC laptop is always updated by company's IT.. I just don't understand why both of my PCs have slow WIFI speed while my older MAC and Iphone have faster Wifi speed..

Yes, I tested all 3 bands and 3rd band seems has best performance.  I used WIFI analyzer and got 2nd and 3rd band unused channels set in router..  I even enabled and disabled smart connect too and saw weaker performance overall if enabled..

this doesn't tell me what wireless chipsets they're using. And "should have all updated chips" doesn't mean that the drivers are current. 

go into your device manager and look at the driver on the wirless. then compare that to the actual device makers driver.

Yeah. I just checked driver version on work PC and it's 6 months old so updated to latest version from Intel for Intel(R) Wi-Fi AX200 160 MHZ to version 21.80.2.1 and rerun the speed test and it still showed 39 mbps. Smiley Sad   Router is only 5 feet from this work PC..

If it was all devices having the issue, I'd easily point at the router and blame it. But all devices but 2 are getting full speed. That makes me suspicious of the windows settings/system settings on those devices. 

What modem are you using from spectrum?

Yeah. That is why I didn't blame router at all because it is doing fine for OS-based devices..  The Spectrum modem is Hitron model E31N2V1.   I will contact my center's IT why my work laptop has very slow speed. Maybe he'll have some answers for PC..

Lol. Even my center IT was puzzled too.. I was doing test for him and he was even more puzzled.

I tested wifi prior to LAN connection for my work PC and it was 141 mbps (better than in the morning as indicated above at 20mbps) then connected LAN (disconnected all 3 wifi bands) and ran the test and it showed 114 mbps on 400 mbps Spectrum Modem.

 

I just ran my personal iphone over wifi and it showed nice 454 mbps which is better than in the morning as well..  This whole thing is SO odd..  I definitely blame window 10 + netgear R8000 model compatibility somehow..
