No file in /sys/firmware/efi has nvram in its name: ls -l /sys/firmware/efi Bluetooth: Generic Bluetooth SDIO driver ver 0.1 mmc1: new ultra high speed DDR50 SDIO card at address 0001 P.S.1 The command dmesg | grep -i brcm produces no output. I am aware of the detailed answer in this question:īut I don't see any Wireless SDIO adapters discussed there. I guess their advice is not terribly useful for me, since even if I still had access to the MS Windows driver file, or if I had downloaded the EXE file, it probably is not in the same format as what Ubuntu needs. They also provide a link for downloading driver patches, as a MS Windows EXE file.
They then outline a process whereby MS Windows users can find the appropriate driver on their computer and apply it. (I don't know if it's a generic description, or can in fact identify the exact model number).

In the PDF document, they tell that the model I have (W1001PB46FD) is a Dual Band Wi Fi Model, and the WiFi card in it is, apparently a "Broadcom 802.11abgn Wireless SDIO Adapter", whatever it means. ("Windows 10 Update results in no Wifi – Click Here for Fix Procedure"). Since then, I discovered that the manufacturer posted a document on its site with some advice for the users MS Windows users similarly afflicted by a WiFi trouble on these PCs:
The usual tools for identifying the WiFi card (lspci, lsusb, rfkill) did not tell anything useful dmesg told about some SDIO stuff, but not a lot of details. As I wrote in another question, Lubuntu 19.04 does not see wifi network card on a CORE+ 10.1 ultra portable PC, I installed Lubuntu 19.04 on aīeantech CORE+ 10.1 Ultra Portable PC (basically, a tablet with an attachable keyboard model W1001PB46FD), but could not get WiFi for work.
