Since I uninstalled root firewall, I've been facing a lot of bugs concerning network connectivity; I lost tethering access and the internet became so slow. Even browsers have reported "connection refused" issues.

How to fix this?

  • Which specific firewall are we talking about?

With the help of a root browser, navigate to /system/bin/ and clear the content of the following files: iptables, ip6tables (using the text editor that comes with root browser) then set permissions for each file to read & execute only. (Remark: This will also restore tethering access)
