I am experiencing some unusual behaviour on my OpenWRT router and want to rule out any chance that it has been hacked.
One of the issues is that everything connected to it seems to have a perceived delay as if it is going via another site or route.
I tried changing my DNS on my phone to Cloudfare and OpenDNS to see if it improved things but it is still going via my OpenWRT router which can't be avoided as it is the underlying source of the connection to the Internet
If it has not been hacked then are there any things that need to be flushed (I imagine with a boot script which I could run at 04:00 for example with a reboot (if that can be done)?.
Any help or suggestions would be appreciated.
