Hello, I am working on a project where I need to be able to modify a wireless adapter's firmware. I'm trying to use the Netgear WN111v2 with the carl9170 driver and firmware. Depending on the configurations I set when building the firmware, I get one of two errors when I try using the device: 1)failed to parse or 2)tainted. See below. What I did: I made the toolchain and got the tools and libs. Then ran ./autogen.sh and selected some configurations. Then copied the new carl9170.fw file to /lib/firmware and changed its name to carl9170-1.fw. (Followed the README https://github.com/chunkeey/carl9170fw) Here are the errors: 1) If I select 'no' to all options during the autogen configuration, this is the error I get when inserting the device: [505796.463525] usb 1-1.4: new high-speed USB device number 15 using ehci_hcd [505796.679353] usb 1-1.4: reset high-speed USB device number 15 using ehci_hcd [505796.810127] usb 1-1.4: driver API: 1.9.4 2011-08-15 [1-1] [505796.810132] usb 1-1.4: firmware API: 1.9.9 2013-10-25 [505796.810135] usb 1-1.4: Unprotected firmware image.
