Solution
!!..PD..!!
Some ONTs have bridge issues where it won't work when the bridge profile mac on ONT and the PPPOE wan mac on the router are same. To bypass it, follow the ONT bridge configuration steps (Non Alphion Based):

Note: Do not DELETE other profiles until you create Bridge profile and save/add it.

1. Take Backup of ONT in working state.

2. Take screenshot of WAN status Page with PPPOE and Voice (if you use then don't delete it). Make sure to include your PPPOE WAN MAC from that status page in screenshot as you need to enter it on the router.

3. Create Bridge profile with MTU 1500, Enter your PPPOE vlan, Service mode Internet, 802.1p (null), Disable the LAN DHCP and bind the LAN ports with the bridge profile.
Hit add/save

4. Delete...

Pretty stable if you ask me. I wonder why your mtu isn't 1492 😅

I hope you tried to measure mtu when u made PPPOE on pc directly.
Also, if websites working directly but not when using router then it must be something related to configuration..
Like works on Ethernet but not over wifi or something like that.

Its 1480.

1452+28=1480
it was set on 1460 that was causing the problem. though also tried the value 1480 manually putting there.
but as of now removed all the ovveridden setting and set that for automatic (1500), sites are opening again.

Today i visited another LCO in our area, they also provide BSNL and other two local operator Alliance Broadbrand and GTPL KCBPL broadband. and somehow he also told he can set up a JioFiber if i want.

Tested the bsnl connection at his office, in fast.com the loaded and unloaded difference is minimum. 9ms vs 32ms. It was like that for me also, but now without QoS it goes above 200ms+ mostly touching 500ms.

also tested on waveform for a detailed bufferbloat testing there results were similar like my current connection.

Thinking of changing my connection there, but confused. @!!..PD..!!

Why turn off QoS? It's to control bufferbloat afterall.
Even for him the latency fluctuates quite high as the distance increases. Check Singapore latency for example in his screenshots..
People who live close to the capital city usually have lower ping to nearby servers and show lower loaded latency for those servers.
E.g: I am 600-700 kms away from Mumbai which is let's say 20 ms but I get 7 ms latency to my gateway. In this scenario if I run MTR (pings to all the hops non stop) for Gdns then loaded latency is less to the gateway which is 7 ms away but much more to the 8.8.8.8 which is 20 ms away.

The last time I used jio is 2 years ago but I remember it had bufferbloat issues too. Loaded latency was high as well plus CGNAT like cherry on top of a cake but no QoS or way to lower the latency. Maybe using a router in front of it making it triple nat from double I could've controlled it but I didn't do it.. With BSNL it made sense to get a better router as it offers Public IP for my location and it's worth the money tbh with QoS.. Ofcourse 100 mbps plan does make a difference as it doesn't make it feel slow when QoS is set.

That could be a problem.
Ask him if he can do bridge mode before you get a connection from him. Some avoid bridge mode.
Mine is old connection and I didn't switch the LCO when there were some issues because this one doesn't care about whether I use bsnl approved ont or bridge mode..
