I also have full one with higher power - but works only in router MT7621 (2xMIPS with HT - so, 4 cores - 880MHz). My laptop PCI don't see this cards (some quirks probably for PCIE required?). BTW, ath9k pcie works fine in MT7621 while ath10k not :) Seems PCIE standard is "not the same" :) BR Janusz > On 22/06/2018, Janusz Dziedzic <janusz.dziedzic@xxxxxxxxx> wrote: >> 2018-06-22 16:48 GMT+02:00 Stanislaw Gruszka <sgruszka@xxxxxxxxxx>: >>> Hi >>> >>> On Fri, Jun 22, 2018 at 10:37:35AM +0200, Janusz Dziedzic wrote: >>>> Have this card in my laptop: >>>> 02:00.0 Network controller: MEDIATEK Corp.
