This issue appears to persist since 2016 across Surface laptop family.

On a Surface book 3 (no dock), sporadically, SurfaceTConDriver generates a (typical) sequence:

That (typically) leads to random Wi-Fi disconnects (6062 - Lso was triggered), and intermittent application failures thereafter.

    Hi SergeBerger-0066,

    For Wi-Fi connection issue, have you reset the network already? If you haven't, on your Surface device kindly go to Settings > Network & Internet > Look For Network Reset. It takes 5 minutes before the reset will take place and it will restart your Surface device.

    You can also go to the hardware manager -> network adapter -> Intel AX201 -> Advanced -> MIMO power save mode -> Change "Auto SMPS" to "No SMPS". While this resulted in the bug occurring less frequently, only changing the setting to "Static SMPS" (-> disabling MIMO) eliminated the problem entirely for me.

    For driver issues, I hope you do a sfc scan on your Surface device. This will scan and detect corrupt drivers and fix them.Type CMD on the search box next to the Windows icon and run it as administrator. Type, "sfc /scannow" and let it complete.

    For app glitches, we would like you to run the compatibility troubleshooter to further resolve the issue. Just right-click on the app, select Properties and run the compatibility troubleshooter.

    Best Regards,
    Wesley Li

    Hi Wesley, thank you for the respond.

    Unfortunately, the entire sequence of the proposed actions did not result in a fix (albeit I had to restore VPN, and reconfigure three apps after network reset). The hope was disabling MIMO; however, that did not help either.
    It is not a huge surprise, since all suggested actions are generic and palliative in nature.

    There is a need to decide whether it is a recurrent hardware issue, or a Tcon driver bug. It is a frequent problem since 2016 on a Surface platform; please notice that multiple posts about Tcon 0x…186 or Tcon 0x0..e errors were never closed with an ultimate solution.

    Clarity there would lead to a corresponding action: the consumer would potentially replace the laptop or have a an ultimate software fix. In my case, it is a brand new Surface Book 3 that started exhibiting the problem after two months of use.
    Thank you for your support.
