thanks for saying MT, nobody does, but thinks, it really helps,

Gigabyte GC-WB1733D-I

well the driver would be from them, first. it is their card.

Can I guess, the PCs are in fact connected to wired ethernet first, if not Pnp is not going to work.

ETHERNET IS first, then we PNP the wifi card 2nd,  or is mostly hopeless, (chicken and egg deal there)

or use sneaker net, old name, means get the driver via PC that  is on the web and sneak it to the dead wifi box.

the endless ageless issue here.

is your PC on W10 v1909,  ??????

the drivers are here, for a fact, 

any time a card any card fails for PnP and for sure with ethernet working NOW,  we get the drivers from the makers site, this is what all techs know and do.

it has zero  to do with DELL really,

the  card is X1 card, (they fail to say on there page sadly)  but if fits a X1 slot it is.

and will work in any slot, x4, x8 or X16 but on some PCs only GPU cards work on X16 so avoid that.

just plug it in to X1, and leave it be.

then load the driver,

in device manager, click tab for view  hidden devices,

and remove the (abandon ones there, not ethernet)

we do that to get a clean load. with new card driver from MAKER>
