Hi i have a mate who runs a small bed and breakfast it only has 5 bedrooms so he is using a domestic router (Linksys), he has been using OpenDNS for over a year to make sure no guests can brows certain websites and it has been working fine until last week when he told me it had stopped filtering the blocked websites, i went round and reset his router then i added the correct DNS setting provided by OpenDNS and i changed the WIFI password and the router login password and everything was working fine again, now only one week later you can brows all the blocked websites again so i am assuming the DNS has been changed again.
I will be going to his business in the next couple of days to have another look so any advice on how to beef up the security on the router and how to tell if it is infected would be very helpful, thank you for your time.
