BSNL FTTH
Hello, I have a BSNL FTTH connection with 30mbps plan. But my internet speed hardly crosses 10mbps. My FTTH cable doesn't have any patches or joints since it has been laid out recently. I live in a rural area and there are no homes within 100m of my home so there's no wireless interference.

This is my optical info:
TX power: 0.7dBm
RX power: -16.6dBm
Operating voltage: 3315.1mV
Operating current: 8.912mA
Operating temperature: 53℃

The ONT given to me is an unbranded (no lables, no info in web ui) EPON terminal with 100mbps ports.

I did a ping test from my PC which is connected to the router (TP-Link Archer AX3000) via CAT6 cable

Code: 
Pinging 1.1.1.1 with 32 bytes of data:
Request timed out.
Reply from 1.1.1.1: bytes=32 time=49ms TTL=246

Packets: Sent = 27, Received = 10, Lost = 17 (62% loss)

Also, I wrote a simple bash script to ping DNS servers every 5 seconds and this is the result:

Code:

Sometimes the PPOE stays in connecting state despite having optical signal. I changed ethernet cables for ONT, did iperf test and verified my network, tried wired and wireless network. But no luck.

I'm facing this issue since one month (previously I used to get full speed with stable connection), if I tell my LCO he says BSNL is having a routing issue and this is expected. I tried raising the complaint via customer care number but it gets resolved within few hours without any technician visit.

Raise a complaint here.
 
Visit nearest Bsnl office try talking with jto ask number of your regional manager and complain directly to him.
 
Check your router logs if it is dropping PPPoE when you are testing for ping. Also, check for when and how many times it drops.
Other than that, also do an MTR test, not just with 1.1.1.1 but also with other IPs.
Finally, do a trace and a reverse trace.
 
The TP-Link logs are just informational. For the script, I'm using multiple DNS server and the server is selected randomly before pinging which is enough for my use case. It has worked all these years with other connections. I think there something wrong with the ONT itself
 

Just got a response from a BSNL engineer. The OLT itself is faulty and he is also requesting a new OLT but the higher authority is just ignoring the request since there is only 30 connection. I raised a complaint via cpgrams and it got closed saying I have exceeded the FUP limit which I haven't (only consumed 15% of my FUP limit). I raised an appeal in cpgrams but it looks like a dead-end here :(
