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
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 🙂
