Hello,

Just did a speed test on my laptop and desktop on the same network , one after the other.

Laptop - Lenovo Thinkpad X1 Yoga Gen 4
Intel Wireless AC 9560 160 MHz, i7 8th gen, 16gig ram
Ping 9 ms
Download Speed : 108.48 Mbps
Upload Speed: 18.81 Mbps

Desktop
ASUS PCE-n15 11n Wireless LAN PCE-E Card,
i7 6th Gen, 32 gig ram
Ping 10 ms
Download Speed : 22.53 Mbps
Upload Speed: 18.81 Mbps

Router here https://www.tp-link.com/au/service-provider/xdsl/archer-vr16…

BOTH computers connected wirelessly, located on the same desk, test done immediately one after the other.

Any idea why the massive difference?

Is it because my wifi card on the desktop is 11n ? Would changing to an AC card fix this?

    My Laptop and home desktop have AC WIFI and get over 80mbps download

    Get another card / wifi adaptor for your desktop to check.

    Fairly sure my desktop USB wifi N adapter gets 30mbs on my connection (which is my max).

    Wouldn't hurt to get either a new pcie card or usb wireless adapter.

    In one word, yes. See this page for more information on the differences between N and AC: https://www.forbes.com/sites/gordonkelly/2014/12/30/802-11ac…

    I'm assuming your laptop is connected to your router on the 5Ghz band.
    Looking at specs of your Desktop WiFi card it only supports 2.4Ghz.

    Can you try connecting your laptop to the 2.4Ghz network and see if its closer to the desktop speed?

    I know when I connect my phone to the 5Ghz network, its much faster, however the range isn't good.
    But I've done speed tests where I'm right next to the router on my phone and 5GHz seems to achieve much better speeds.

      Ah okay - this explains a lot - I didn't realise why the 5g network didn't show up in my desktop.

      Thanks so much.

        I find a huge difference in performance between 2.4 and 5Ghz on my phone. 5Ghz with 1 bar out of 4 still beats 2.4 with full bars.

  • stirlo on 28/09/2020 - 12:45

    Yes it's that obsolete wifi card causing the slowness.

    Jump straight to 2020 and get an Wifi 6 AX card from your desktop.

      Thanks so much! Can't wait for it to arrive.

      These are also available for laptops if anyone wants to upgrade theirs. Would need to check specific models, but the existing card can be swapped out pretty easy in most gaming and regular laptops, just like ram or a drive.

    What antenna arrangement does your wifi card have? I have a TP-Link T9E AC1900 which has the antennae directly on the back of my pc case and the wifi reception is absolute trash, even with an access point that is only a metre or two away - I suspect it's getting some really bad interference from something in the case.

    If you're going to get a wifi card, I'd recommend getting one with an antenna that doesn't mount on the side of a big metal box.

      Your computer case will obstruct LOS from antenna to router but apart from your Wireless adapter itself, your computer doesn't emit any other kinds of radio waves (apart from Bluetooth perhaps) meaning your WiFi issues are something to do with external factors.

      Like the shape of the transmission pattern of your router, interference from another device (TV, Microwave over, Baby monitor) or some other obstruction that's causing performance loss.

      Try moving your router to a different spot.

        Hmm interesting. To test your theory, I just pulled out the LAN cable (I have a RBK20 access point <1m away from my desktop) and I'm still saturating my internet speeds on WiFi.

        The only thing I've really changed out is my screen from a DVI connected U2711 to my C34H892 via Displayport and don't currently have my wired keyboard plugged in via the back USB ports - I wonder if possibly the DVI cable physically touching the antenna made a diff?

        Previously I used to get 2-4x file transfer speeds with the LAN cable compared with the wireless connection, to a NAS also attached to the same RBK20 via LAN.

    The Asus card is simply too old (doesn't help that the last drivers Asus released were in Oct 2015, and the can't won't work with newer Realtek chipset drivers). Buy a newer card with a far better Intel chipset & drivers for use (also provides Bluetooth support):

    Cheaper/older option (WiFi AC, Bluetooth 4.2):

    Note: You'll need to connect the PCI-E card using the cable provided, to an internal USB2 motherboard header to enable Bluetooth for use.

      Thanks! Just got a new card and um at 100 Mbps + now :) Thanks for all the information - I wouldn't have realised about the bluetooth cord if you didn't tell me
