I got my BSNL FTTH (777)connection yesterday. I am currently getting the advertised speeds on downloads and streaming, but browsing speeds had slowed down considerably. Twitter and Facebook takes some time to load. On banking sites and sites like Paytm , Amazon , Flipkart , PhonePe and every other site out there, the payment portal won't connect. This is a serious issue. This issue never arose in my previous connection. Please help.
using custom dns or automatic?//

Whatever comes as default. I haven't done anything to DNS, since I would be totally lost if any issues arose, as the BSNL employees lacked knowledge regarding FTTH connection.
this probably wont help. but does not hurt. switch to // That didn't work out as expected. My ONU is
Ustarcom 404i (2008 model). It is a GePON with only FE port connected to a TPLink router. Any help is appreciated.

if you are using tplink router then configure the custom DNS there, rest of the devices should pick up that custom DNS.
