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

    --Slow WiFi SOLVED--

    Wifi speed on my Surface Pro 7 became quite slow around early November 2020. After this I used other machines, as speed was needed. 

    That happened after updating Win 10 to the 20H2 version due to a newer driver installed for the Intel 6 AX201 160 MHz card.

    Connected to my 5G network at home (802.11ac), before such 20H2 update, the tested Pro 7 download speed was around 400+Mbps and the upload speed about 300 Mbps.

    After the 20H2 update, download plummeted to a meager 25-30 Mbps while upload remained at some 300 Mbps, suggesting no hardware failure.

    Other machines at home, including an older Surface Pro 3, didn't suffer any slowing down and this excluded router or settings issues.

    I had tried tweaking various driver advanced parameters, download/install the latest 22.40.0.7 version by Intel, and several other older driver versions. I also contacted Intel for support to no avail (they suggested to contact Microsoft). I had read somewhere that the Pro 7 was originally equipped with a custom driver version by Microsoft.

    An expensive, forlorn Pro 7. After months unused, the other day I decided to take another look.

    Luckily, after several Win 10 updates and uninstalling/deleting driver versions, the "good" driver version by Microsoft was still in the disk and I found it by manually searching. Tried it and this one SOLVED the issue although not forever, as a more recent undesired driver is being installed at the first occurring automatic update. It happened already and I'm now looking for possible ways to selectively block future driver updates for good.

    Hope this helps other users.

    Needless to say, it's tiring. A little effort by Microsoft would be highly appreciated to keep customers happy at least on their own branded hardware. 

    Regards,

    Ant

    2.4MHz? That’s the slowest WiFi band, great range (with more interference and only three “true channels”) but dire throughout.

    5GHz is much faster.

    I have now sold my SP7 and bought an M1 MacBook Air, but the fix I posted at top of thread worked for me and I never had the issue again.
