I get the 404 error on 192.168.1.1 too. Http://192.168.1.1:1471 and http://192.168.1.1:1471/cgi-bin/status.rb work fine, taking me to jasager. But I cannot get to openwrt. I have tried installing haserl and webif putting them both in /tmp/ and using opkg install haserl_0.9.24-1_mips.ipk and all I get is no such file or directory. I am using jasager firmware install.
Also /www/ is empty.
