Seems it’s a old wireless Router. no new firmware released now.

Why I want to upgrade firmeware ? just for fun. didn’t feel much improvement. 🙂

Just got a official link

http://osdn.jp/projects/sfnet_officiallinksysfirmware/downloads/wap4400n/1.2.19/WAP4400N_GPL_v1.2.19.tar.bz2/

I had to use an GCC 3.x box. so I choose CentOS 4.8. so old.

Download firmware from above link, following the cross compile guide. will be straight forward.

Packages installed: gcc bison flex gcc-c++ zlib-devel

After a looong compile. got the new firemware 1.2.19.

Upgrade by your own risk 🙂
