New 1GBPS BSNL connection in Bangalore (CG-NAT?)

[SpeedxThunder]

So, i just got a new BSNL connection few hours back. i opted for the RUBY OTT plan which provides 1gbps plan for 4799

surprisingly my lco is using GPON but One thing I noticed is that i am under cg-nat

But everything else seems to be super fine like routing and pings and stuff

peering seems to be excellent

But i am unable to use it with third party ont, if anyone have any idea please share

There is a comment by someone in some thread here from a little while ago about getting CGNAT address. I think it was from KA. Best guess is IPv4 address exhaustion in the region.

They have also made some changes like not allowing third-party ONT by simply doing ONT MAC address and WAN MAC address authentication. You might be able to bridge and use your own router after getting the WAN MAC reset. ONT might also be remotely managed via TR069.

Btw which ONT did they provide?

they provided Digisol DG-GR6821AC

Wow. Why is your download latency such low?
I also have the same router(plan 100mbps) and for me the ping and upload latency are good when doing speedtest(via gig lan to pc), but upload latency is all over the place. Varies from 180-450.
I also has seen speedtest results of bsnl ftth users on r/bsnl and they also seems to be having high upload latency.

Is it because of your gigabit connection and therefore getting high priority or special connection?

Also when connected via 100mbps lan(old lan wire), download latency is close to ping. So i thought it was due to shittty Digisol router.

It's due to two reasons.

Buffer bloat in your case.
And in-adequate system in his.
His system is not strong enough (or he is doing it via a browser) to choke the entire 1G, hence the latencies are lower.

@Lolita_Magnum , I didn't get it. When the same router is able to handle 1gbps without bufferbloat, why can't it handle at 100mbps? As it is powerful enough to handle gigabit.
Additional info, I tested via speedtest android app, on firefox on linux and speedtest-cli(official one) and got similar results.

Also I have TP-Link AC1200 C6 wifi router with openwrt. Will this help in reducing download latency, if I put the Digisol one in bridge mode

Buffer Bloat is NOT due to routers; it's due to how ISPs configure shapers (100Mbps in your case) for each connection.
Basically, you are able to choke the entire provided bandwidth, while he isn't.
