Hi, I'm developing a captive portal with OpenWRT and NodogSplash, and have a few test devices. Right now I'm having issues with one. The router I'm using is an Archer C7 v4 and I'm connected to another router, a Technicolor TG789BVN.
So far I haven't been able to identify what's causing my problem. The thing that happens is that my router might or might not assign IPs to devices connected. If it assigns an IP, when the user gets prompted to enter to the captive portal, it won't display my local webserver, instead it will show the default view like if the webserver didn't have a file in it (index of directory, etc, etc).
If I try to SSH to the router, it will tell me that my password is incorrect, and will only work again after I restart the router.
If I'm connected with my laptop (which isn't restricted by the captive portal), I have access to Internet.
Things I have installed recently are: hostapd-common, hostapd-utils, wpad-mini, iwinfo,
These are the errors I get in the logs:
