WNDR3700V2 DNS resolution

[Davee3]

New to this stuff  Have run DNS resolution tests on 2 computers on same router  one says using internal dns  192.168.1.1 & the other a level3 communications server 4.2.2.1 resolvers.level3.net

The internal is faster  1? - why different for the 2 computers - both hardwired to router?   2? can this be changed for the slower unit 4.2.2.1?

The slower unit is actually a faster computer but often delivers webpages slow or not at all 3? Whats going on ?

Whoops ! Turns out during a tech mainteanace activity the DNS search was converted from automatic to manual  with 4.2.2.1 as IP . Not sure if this was the cause of delays but highly likely

Hi @Davee3

Welcome to the community!

What's the OS of the two computers? 

Are the DNS addresses assigned statically or dynamically?

Try flush dns command on the computer that has a slow connection. 

[Davee3]

Both are windows 10 with all updates allowed automatically     DNS assigned automatically   Flush? will dig in to how 

[ElaineM]

You may go to the command prompt and type ipconfig /flushdns then hit enter.

@Davee3 Is it working now?

[Davee3]

Yes seems better - never was a router problem - choice was wrong in the offending computer

Thank you for the update!
