Hi all.
I am using OpenWrt 24.10.0 and got OpenNDS to run with the hint: opennds.@opennds[0].use_outdated_mhd='1' option login_option_enabled '1' option login_option_enabled '2' working for me.
option login_option_enabled '3' the captive portal appears and when I try to log in with username and password I am redirected to the next page and click on the Continue button. When I do this, it takes me back to the first page. So I can't get on the network.
Can someone look at my problem?
