Lenovo slow on network; all other devices at normal speed

    Lenovo Thinkpad Yoga circa 2014 (type 20C0S19700)
    Windows 10 (64-bit)
    Intel Dual Band Wireless-AC 7260

    Beginning yesterday morning, my laptop has been connecting to our home network at stunningly slow speeds (always sub-1Mbps, usually more like 0.1Mbps).

    This is in 'normal' mode; when I start in safe mode with networking I test at normal speed (4Mbps down and up- we live in Costa Rica, where this is considered good!).

    My wife's Lenovo laptop and our Android phones are consistently connecting at the usual 4Mbps down and up.

    I uninstalled Intel Proset Wireless software- no change
    ...Ran scans with updated versions of Bitdefender, Malwarebytes, and Superantispyware- no change.
    Then removed all 3- no change.
    Ran an offline scan with Windows Defender- no change.

    I updated some drivers last night because I was also having trouble connecting to an external display, and after doing so, the speed was normal for a short while. As of this morning and for the past 4+ hours it's back to super slow.

    Ethernet connection is slightly better but still far slower than all other devices on the network.

    I'm stumped.

    THIS is the most current Windows 10 64-bit driver (21.10.1 - 18.33.17.1) for the Intel Dual Band Wireless-AC 7260 device.

    Thank you. I reinstalled that driver but no difference.

    Just flushed DNS and restarted everything too; no luck there

    0.13 Mbps download | 0.14 Mbps upload | latency 2339 ms

    Update: I connected via ethernet and shut wifi off, and am now testing at normal speed. Does this point to a problem with the network card? Or software?

    What's not in play when I'm connected via ethernet (in 'normal' mode) and wirelessly in safe mode?
