If it's a particular Mediatek chipset, then the firmware for it may be in the firmware-linux-nonfree metapackage - which also pulls in firmware-misc-nonfree which is the package where the actual driver is. 99% of current wireless chips need additional firmware to operate correctly. https://packages.debian.org/bullseye/firmware-linux-nonfree The fact of having trouble installing via wifi is one of the reasons why I've started suggesting that people should use the unofficial installer which includes non-free firmware for wifi chipsets. If anyone wants to use the official image to install - it will generally work for wired connection over Ethernet - which would also allow you then to add the non-free firmware for the wifi card. [For a virtual machine, the official image is ideal because that then depends on the host machine anyway.] If your card needs firmware, then it's quite possible that the official installer doesn't configure it - though you do get a prompt saying something close to "Your device may need nno-free firmware. Use non-free or load firmware now" Hope this helps, with every good wish, as ever Andy Cater
