The PCI device ID detected by the wifi drivers on devices using a fallback SPROM is wrong. Currently the chipnum is used for this parameter. Most SSB based Broadcom wifi chips are 2.4 and 5GHz capable. But on devices without a physical SPROM, the only one way to detect if the device suports both bands or only the 5GHz band, is by reading the device ID from the fallback SPROM. In some devices, this may lead to a non working wifi on a 5GHz-only card, or in the best case a working 2.4GHz-only in a dual band wifi card. The offset for the deviceid in SSB SPROMs is 0x0008, whereas in BCMA is 0x0060. This is true for any SPROM version. Override the PCI device ID with the one defined at the fallback SPROM, to detect the correct wifi card model and allow using the 5GHz band if supported. The patch has been tested with the following wifi radios: BCM43222: b43: both 2.4/5GHz working brcm-wl: both 2.4/5GHz working BCM43225: b43: 2.4GHz, working brcmsmac: working brcm-wl: it lacks support BCM43217: b43: 2.4GHz, working brcmsmac: it lacks support brcm-wl: it lacks support Signed-off-by: Daniel González Cabanelas <dgcbueu@gmail.com> [amend commit description, rework patch to avoid using a new global variable and keep ssb sprom extraction code as close to ssb/pci.c as possible] Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com>
OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Sunshine!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev rsync
Quickstart
-
Run
./scripts/feeds update -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
Run
make
to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg
. If you're looking to develop the web interface or port
