 +====== Linksys WAP300N ======
 +
 +Linksys WAP300N simple wireless router which has 2 detachable antennas and 1 LAN connection.
 +
 +**Currently SoC is not supported.**
 +
 +You can apply [[http://chui-pas.net/~fun/wap300n/wap300n.diff|this patch]] to linux v5.9 and use [[http://chui-pas.net/~fun/wap300n/wap300n.config|this config]], to build a kernel that boots to a console prompt.
 +
 +Generate an uBoot image with:
 +
 +<code>
 +mipsel-linux-gnu-objcopy -O binary -R .note -R .comment -S vmlinux zImage
 +lzma -9 -f -S .lzma zImage
 +mkimage -A mips -O linux -T kernel -C lzma -a 80020000 -e 80020000 -n "Linux Kernel Image"  -d zImage.lzma um_factory_fw.bin
 +</code>
 +
 +then serve that um_factory_fw.bin via tftp from 192.168.1.100 to 192.168.1.1
