@Helio2k I am having this same problem. I just tried changing turning off the Auto DNS and added 8.8.8.8 for the Primary DNS and then 8.8.4.4 for the secondary DNS. Will let you know if that changes the problem. Also, I emailed support to get the internal firmware upgrade, but so far no response, thanks

@Abhi_2020 this worked for me:
Go into Deco App, More->Advanced->IPv4,
- Turn off obtain DNS Automatically.
- Set Primary DNS to 8.8.8.8, 2nd to 8.8.4.4
