Currently, EAPOLv2 (802.1X-2004) is used by default for legacy clients that are not WPA2 (RSN) capable. These legacy clients are often intolerant to this EAPOL version and fail to connect. hostapd.conf upstream documents for eapol_version the following and that this is a known compatibility issue with version 2: // IEEE 802.1X/EAPOL version // hostapd is implemented based on IEEE Std 802.1X-2004 which defines EAPOL // version 2. However, there are many client implementations that do not handle // the new version number correctly (they seem to drop the frames completely). // In order to make hostapd interoperate with these clients, the version number // can be set to the older version (1) with this configuration value. // Note: When using MACsec, eapol_version shall be set to 3, which is // defined in IEEE Std 802.1X-2010. //eapol_version=2 For the wpa parameter, hostapd.conf upstream documents that this is a bitfield, configured as follows: // Enable WPA. Setting this variable configures the AP to require WPA (either // WPA-PSK or WPA-RADIUS/EAP based on other configuration). For WPA-PSK, either // wpa_psk or wpa_passphrase must be set and wpa_key_mgmt must include WPA-PSK. // Instead of wpa_psk / wpa_passphrase, wpa_psk_radius might suffice. // For WPA-RADIUS/EAP, ieee8021x must be set (but without dynamic WEP keys), // RADIUS authentication server must be configured, and WPA-EAP must be included // in wpa_key_mgmt. // This field is a bit field that can be used to enable WPA (IEEE 802.11i/D3.0) // and/or WPA2 (full IEEE 802.11i/RSN): // bit0 = WPA // bit1 = IEEE 802.11i/RSN (WPA2) (dot11RSNAEnabled) // Note that WPA3 is also configured with bit1 since it uses RSN just like WPA2. // In other words, for WPA3, wpa=2 is used the configuration (and // wpa_key_mgmt=SAE for WPA3-Personal instead of wpa_key_mgmt=WPA-PSK). //wpa=2 For client compatibility therefore: EAPOLv1 (802.1X-2001) should be used by default where WPA is enabled. EAPOLv2 (802.1X-2004) should be used by default where WPA is disabled. To fix this, we can therefore change in the script: set_default eapol_version 0 To the following: set_default eapol_version $((wpa & 1)) This therefore: 1) Sets eapol_version to 1 where WPA has been enabled via wpa bit0 being set. 2) Sets eapol_version to 0 where WPA has been disabled via wpa bit0 being unset. For usual configurations that only have WPA2 enabled, EAPOLv2 is then used. Signed-off-by: Nick Lowe <nick.lowe@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 -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo 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.
Related Repositories
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
packages to OpenWrt, please find the fitting repository below.
