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

    There is a driver update available from Intel.

    21.90.3.2 for AX201/AX200/9560/9260/9462/9461 (Only available in 64-bit version)

    I'm giving it a shot to see if it resolves my issue permanently.

    The release notes have a line item: "Reduced Wi-Fi throughput on specific channel."

    I'm hopeful.

    Following up on this... I continue to see this issue, so I no longer think that the particular settings that I changed make a difference. When I encountered the issue again, I changed the "Throughput Booster" setting back to Disabled, and I got higher speeds. Now I'm guessing that just the process of changing an adapter setting resets the WiFi adapter so that it starts working properly again.

    Had a "systems update" the other day.  I thought "I bet Microsoft has fixed this issue on the surface 7".  Checked my wifi speed and it's........tada!  22.8MB/sec.

    Pathetic................

    Hello from Japan.

    I have same issue on Surface Pro 7 Core i7. I performed the throughput test using iperf3 between surface pro and other Windows10 PC via buffalo WXR-5950AX12(WiFi 6 AP) as result below.

    As others have reported, the problem does not occur with IEEE 802.11n settings. The problem only occurs with 5GHz IEEE 802.11ax or 11ac.

    Of course, the performance of Surface Pro 7 cannot be demonstrated with the IEEE802.11n setting. Microsoft should recognize and resolve this issue as soon as possible... ![](https://learn-attachment.microsoft.com/api/attachments/f5c2548f-249c-43c7-a063-c869b2ff8e2b?platform=QnA
