Huge packet-loss on the route and spotty link

[pufl]

I have finally bit the bullet and have subscribed to the 40Mbps 645 plan with plans to upgrade if things work-out. They have finally laid the cable and gave the fiber connection a day ago with the AONT-100 GPON ONU in Hyderabad. The modem configure to be in bridge mode fronted by Nighthawk X6S on its latest firmware. The connection is over Ipv4 backed by Google DNS and I get allocated the 117.200.x.x IP range. While I do seem to get the promised 40Mbps up/down on speedtest and fast.com, my connection is quite spotty with disconnect blips happening every 3-5 seconds. This makes any Facetime call / RDP session almost unusable which, quite frustrating. Even a remote teamviewer connection is spotty, with disconnects/reconnects every few seconds. I have run ping tests on various AWS regions, and I saw 2-3 seconds of good RTT followed by 2-3 seconds of very high RTTs ranging from around 300ms in DigitalOcean BLR, to around 2000ms for a node based in New York city.

I have set MTU to 1460 which seems to be the sweet spot based on my pings to google DNS. I was thinking of why so many disconnect blips a.k.a packet drops (?) are happening on my connections. I ran MTR on a bunch of nodes and regions, and it doesnt look good so far with a ton of packet loss on its path. Almost all my out-of-country mtr requestes get routed through NCR region (218.248.235.141, 218.248.235.142, 218.248.235.xxx) and that is where there is a obscene level of packet loss happening.

Please help!

My questions:

Does this happen to folks in Hyderabad and other parts of the country experience this as well ?
Am I all interpreting this wrong ?
What could be done and how can I approach this issue with BSNL ?

I am attaching all the screen shots I have for context.

loss at intermediate hops are fine because you won't be directly contacting these servers ( 218.248.235.x)

The pings you are getting are around what you should be getting . I'm getting ~50ms ping to 218.248.235.141 which means the servers are likely not located in NCR but likely somewhere in South India.

According to Complete IP Address Details for 218.248.235.141 it seems to be in Bangalore but geolocation isn't always accurate.

I will try to read further into your traceroutes.

Edit 1:

This time I used RIPE Atlas, 218.248.235.141 does seem to be in Bangalore

This is what mtr to 23.36.39.156 gives me from ACT

@pufl I would suggest starting diagnosing at your end first before going to the ISP.

Try connecting your PC directly to ONT and use the ONT for temporarily creating the PPPoE connection. This will let you know that the issue is either in the ONT or on the BSNL network

 

[pufl]

@JB700 Fair enough, I have the ONT currently configured in bridge mode (the bsnl guy did it) and now I cant access its UI anymore on 192.168.1.251. You think plugging in the ONT directly into my machine give me that access ?

Also, what should I specifically be looking at once am in their interface you think ?

[JB701]

@pufl You'll have to use static IP settings in Windows on your desktop and put default gateway as 192.168.1.251 then you should be able to access your ONT.

Once you are in ONT, you should enable NAT if its disabled, go to WAN section of ONT and set it to PPPoE and enter your creds. On BSNL you will also need to enter your VLAN I think, it could be configured already on the ONT by BSNL.

it seems like people who are all having the private ip gateways facing this issue.

Frequent Disconnections on BSNL FTTH | BSNL Bharat Fiber Broadband

I recently installed a new Bsnl Ftth connection at my home (preferably for gaming) as I don't have any other option to go for. DL and UL speed are very good all the time even more than the speed limit of the plans, like I have 50 Mbps plan and always get 65-70 Mbps DL and UL on speedtest.net...

Here is the another one. same issue with private gateway but having a public ip. i think this problem persist in BSNL for a long time (from the month of march). Hope there is upgradration going on in bsnl end region by region

So today again all day have been facing intermittent issues in website connectivity, it works for some time then for a few seconds websites don't open and rinse and repeat. Also got a 59.x.x.x series IP which indicates failover to backup system. i have got same 59 series ip but no issues over...

@Elavarasan very interesting, maybe OP should try out a VPN. Check my Cloudflare WARP on Windows guide here: How to use cf-warp and WireGuard? | VPN and Seedboxes to setup one and see if it makes a difference. If the routing problem is across entire internet it may not help but according to your traceroutes, your pings to Cloudflare is low
