The Dell's 7590 wifi card is identified in `lspci` as: 3b:00.0 Network controller: Intel Corporation Device 2723 (rev 1a) From my googling the Dell 7590 seems to have a Killer AX1650 (in collaboration with Intel?) And when uploading a massive image to say S3, for example through CLI or browser, I get the following messages in `dmesg` after a few dozens of MB, at which point the net is killed and I need to turn the wifi off and on again to get online: [234483.616399] iwlwifi 0000:3b:00.0: Microcode SW error detected.
