dns problems

[kamiarapt]

hi. so I ended up connecting another router to my rogers rocket modem (CGN3ACSMR) the second router is DIR-857

now here is the problem at any given time some of the websites are inaccessible I get  This site can’t be reached www.amazon.ca’s server DNS address could not be found.

10-15m later those websites can be accessible and a set of different website get inaccessible

Having multiple routers on a network can cause issues in many areas including DNS, DHCP, NAT and so on. If they're not set up correctly, they'll just end up competing with each other and causing conflicts and errors. 

 

Why do you have the second router on the network? If it's for wireless expansion, see if you can set it to access point mode, as that will likely solve the issue. You could also set all DNS options to the same external DNS server, such as Google's public DNS (8.8.8.8 and 8.8.4.4) which may solve DNS errors.

the second router was mainly for having lan expansion, i searched for that in the router setting but nothing came up

Please provide a drawing of how you have the multiple routers hooked up to each other and your network

so a cable is connected to rogers router then a LAN cable is hooked up to it about 30 feet away to another router

here is another twist on it, it's only happen in google chrome
