I am using ubuntu 18.04.6 Bionic Beaver and wifi adapter is not available.

03:00.0 Network controller: MEDIATEK Corp. Device 7961

Subsystem: AzureWave Device 4680
Flags: fast devsel, IRQ 255
Memory at ff20300000 (64-bit, prefetchable) [disabled] [size=1M]
Memory at ff20400000 (64-bit, prefetchable) [disabled] [size=16K]
Memory at ff20404000 (64-bit, prefetchable) [disabled] [size=4K]
Capabilities: <access denied>

Kernel version : 5.4.0-87-generic

Note: I want to use Ubuntu 18.04 only because the yocto build is working fine in this version.

Is there any way i can download and install the driver for mediatek?

  • You need a new kernel, 5.14 I guess.
