Surface Pro 7 Slow WiFi

Anonymous

Hello everyone,

I am working with my new Surface Pro 7 i5 one or two days now and unfortunately, I still have severe wifi issues after installing all updates. Speed is between 0 and 1,250 kbit/s.

After searching for this issue, I found several entries describing this kind of problem and some workarounds like setting the MIMO Power Safe Mode to a different value. (as described here) I did all this but still, there is no improvement. 

Any other suggestions on this? Is this a known bug? Is there a patch on its way? Is Microsoft working on this?

Any help is greatly appreaciated.

Thanks a lot

Tim

    2GHz is a lot slower than 5Gz (the best analogy is to think of 2Ghz as a long thin pipe that can carry a small amount of water a fairly long way (say 25 metres) while 5GHz is only 5 metres long but is 10x wider so can flow far more water but only a shirt distance. Now replace water with data) :) 

    im not sure what wifi equipment you ise but if you have an option for 5GHz/band steering then use it. Give both bands a different name and only connect your SP7 to the 5GHz one.

    I first became aware of this issue in December 2019 when i got my sp7 and followed the advice below have not had the issue since. 

    1. Navigate to the Start menu, right-click on it and select Device Manager > Network adapters.
    2. Right-click **Intel AX201,**select Properties > Advanced> MIMO power save mode.
    3. Click No SMPSfrom the drop-down menu available on the right.
    4. Now go to the following path: Windows 10 > Settings > System > Power & Sleep.
    5. Choose  When my PC is asleep and on battery power disconnect from networkand click Alwayswhen prompted.

    My network is also very slow compared to my Pro 6 side by side doing the same thing. Chat support was awesome and took over the computer but could not fix it. So they sent me another device and I'm having the same issue. So I went in and manually updated the Intel AX 201 driver. What I finally noticed was my 5g wifi has downloads of 135 Mbps but when I switch to 2g, it plummets to 11. I'm using the speed test on Bing.

    I have not had any wifi issues with my SP7 for some time. I can though recommend the Plugable USB 2.5Gbe adapter, for £30 (from Amazon) if you have a compatible switch its a great purchase. I also bought the QNAP 5Gbe adapter, but the difference in transfer speeds means its hard to justify the increase in price (£100).

    plugable gives a reliable 260 MBps while the Qnap gives around 330MBps. 

    i wouldnt go back to wifi unless i had to.
