hi
i have a rb1100ahx2
433uah
rb1100
all of these i have working as dns server for client connected to them as well as routing
it was working perfectly for a long time
since three weeks ago
i have a problem in all 3 of my router
when dns cache has a number more than 100 cache like those in the photo that i will be putting here
only whatsapp well be unstable
only in downloading video and watching status
when i clear the cache every thing is good for a moment and problem all over again
i tried many dns such as goggle public dns
i had better resault with a local dns address from a company but the problem stands anyway
other friends of mine in the region seem to be okay and dont have the problem
please help
thanks
Those are negative entries, the random names are normal and used by captive portal detection of various OSes. Nothing in that should affect WhatsApp, the problem may be elsewhere.
can you provide me anoher dns server
except for google
a good one
maybe your own router if that is possible
same like me
where the suffix .lan comes from? All "N"egative entries have it.
Good DNSes … Quad9 or Quad1
Make sure your DNS service is not available from internet. Use appropriate firewall configuration!
A DNS service open on the internet means guaranteed problems.
