I am on NeatROM 5.9 (4.1.2 JellyBean) with Apolo Regular Kernel and just wanted to download AdFree via Dolphin Browser, but no matter what website I want to visit; it always tells me that I have got a connection error. After I downloaded AdFree via my PC and wanted to check the Host files, it got stuck there as it wouldn't do anything in the loading screen. Other apps like AdAway got the same error (not wanting to download host files), but apps like Google Play, Facebook, WhatsApp or others work fine. This problems no matter if I am connected with Wi-Fi or with Mobile Data.
My question is: How can I get back my internet connection?
EDIT: Found the problem, DroidWall was blocking these apps from connecting. Just activated then deactivated the firewall and everything worked out
