Flush DNS & reboot router

[bluetoba]

I have a problem that on the browser I often get a message either waiting for <website> or resolving host. This happens oftens.

I have tried clear host cache on chrome://net-internals/#dns

ipconfig /flushdns

but what always work is rebooting my router.

Why is that? do I have to combine ipconfig /flushdns and reboot router?

If I fix it on one laptop by rebooting the router, and go to another laptop that has a problem the previous reboot doesn't work. I still need to do a ipconfig /flushdns and a router reboot separately.

what is the permanent solution? I cannot be rebooting router every 5 minutes.

Is there a way to change dns cache on the router. I am using TP Link VG3631.

1| You may want to look your router's GUI and see if you're on the latest firmware. If not, source it from here and update the firmware for your router.
2| A physical reboot is more of a power cycle for the router.
