- Please see the buyerguide for features you could be looking for.
- Please decide yourself which ones are important to you.
- Then ask in the OpenWrt Forum (or anywhere else) for personal recommendations.
The beginner's guide should hook you up.
Please check current TableOfHardware for the list of supported devices.
Flash devices can be written to, at minimum, anywhere between 100,000 and 1,000,000 times (according to the manufacturers). Keep in mind we have a normal distribution and also, that Flash never ever just stops working, but merely distinct blocks do. I.e. you won't be able to write to them any longer, but you should be able to still read them.

There are claims all over the web, that OpenWrt can only be handled by command-line. That is bullshit. As a matter of fact, there are 3 (three) WebUIs available for OpenWrt: LuCI, X-Wrt and Gargoyle
Although there is actually no reason to fear the CLI.
Also, please do note, that the X Window System is available for OpenWrt as well!
- brcm-2.4: heavily modified Linux kernel version 2.4,
wl(or wl-mimo) proprietary driver,
- brcm47xx: vanilla Linux kernel version 2.6/3,
b43reverse engineered FOSS driver,
wpad(hostapd + wpa_supplicant), standard linux utilites (
It is reported as still debatable which wireless driver is better for stability and performance. brcm-2.4 is still available in the latest OpenWrt stable, but has been abandoned in trunk as of Rxxxxx.
*Note* At least as of 10.3.1 stable, it is possible to build 2.6 kernel with proprietary Broadcom drivers. No precompiled images have been posted yet though. If your target is brcm47xx, it will build 2.6 kernel, no matter what the wireless drivers are. — sup 2012/05/07 11:53
brcm47xx stability issue It has been reported that brcm47xx has issues when router is under heavy load.
ifdef CONFIG_MADWIFI_DEBUG MADWIFI_APPLETS += athdebug 80211debug endif
So first enable the "Advanced configuration options (for developers)" item, then navigate to the kmod-madwifi submenu and tick "Enable compilation of debugging features" on or add/replace "CONFIG_DEVEL=y" plus "CONFIG_MADWIFI_DEBUG=y" manually in .config
CONFIG_ALL=y + make V=99 IGNORE_ERRORS=m
- a factory image is one built for the bootloader flasher or stock software flasher
- a sysupgrade image (previously named trx image) is designed to be flashed from within openwrt itself
The two have the same content, but a factory image would have extra header information or whatever the platform needs. Generally speaking, the factory image is to be used with the OEM GUI or OEM flashing utilities to convert the device to OpenWrt. After that, use the sysupgrade images.
- a uImage is is a tagged linux image expected by the u-boot loader
