Yup, very simple on router that's why I mention for those use modem on PC since usually changing on the adapter screen dont work

under custom dns tab

If maxis over write, put the custom dns ip into DCHP tab. Should also work
using dns does not affect your speed. It only speed up your web search and initial page loading

That is the DNS acquired to the WAN
Try doing ipconfig /all on your PC see what is the DHCP acquired DNS address

I checked mine, once changed the DNS it also changes on the status page, probably you need to perform a reboot.

Else need to manually set at DHCP

Bro I just found a way to change the DNS on ROOter.....

Go to Network > Interface > Wan(wwan0) > Click Edit > Advance Setting > Untick Use DNS Server advertised by peer > Key in your custom DNS. etc. 8.8.8.8 and 8.8.4.4

Restart modem and wait it to reconnect see if it works

This is mine
