Does BharatFibre give you symmetrical or asymmetrical speeds?

So I am currently on BSNL BharatFibre ₹599 (60 Mbps). This is the stated download speed and (touch wood) BSNL has never let me down. I’ve been using for a few months now and always it’s been above 58Mbps, even during peak times.

The weird thing however is the upload. Is it supposed to be symmetrical or not? Cos I’ve had both. Sometime, with certain IP ranges, I get perfectly symmetrical speeds. And then reboot the router, new IP range, and the speed becomes exactly 50%. Consistently. I get perfect 60/30. I use EPON which generally supports symmetrical whereas GPON can support but usually follows the Upload 50% of Downloads rule.

I understand speeds are controlled by BSNL and not LCO’s OLT since it’s just a simple layer 2 switch. Anyone else faces this? Is it a weird BSNL quirk?
 
@pillaicha It is supposed to be symmetric and you should be getting 60mbps upload.

May I know where/how you are testing upload speed?
 
I use OVH cloud or any other Singapore cloud server , Karnataka routing has become good these days . Getting symmetrical speeds on multiple servers. Google Drive and Onedrive upload can also be used to test the speeds

If you are getting 60/30 exactly then there is some configuration issue at some point
 
No I don't use Firefox. Do you think a L2 switch such as an OLT can limit line rates?

I think this is what it is. Something‘s up that’s causing this very intermittently with certain IP ranges only. It’s always 60/30 and with some IP‘s it is 60/60. I can’t figure out a pattern but it doesn’t depend on whether if it’s peak time or not. It’s mostly dependent on the IP I am assigned.

Okay, These sites should be fine.

If you are testing in Firefox, I'll suggest testing in Chromium or through the CLI clients of these services. FF has a bug and because of that, Upload speeds are anywhere from 1/3 to 1/20 times slower than what you can get in chromium. (1596576 - Upload speed is so slow in Firefox, all other browsers are fine (please read detailed explanation))

Otherwise, Probably file a complaint, Not that that'll lead to a lot of change. :/

Is it? I've never encountered this.
I use FF on Ubuntu and I always saturate my 100mbps (50mbps on old plan) uploads to India and even Singapore AWS.
And uploads to youtube and gdrive saturates too.
 
@shin Yes, I have this problem on Windows/Linux and several other people in the bsnl Telegram group also have this problem.

In my case(and in a lot of other cases) upload speeds to onedrive, youtube, gdrive, google photos is limited to ~30mbps and it's so consistently limited at 30mbps that I initially though BSNL was deliberately throttling my connection. :/
 
So then run a Live boot of Ubuntu or any light Linux ISO through a USB stick and check the speeds. But didn't he report the same on Mobile also ?
 
@shashankb OP is facing some other issue.. I just responded to the person who asked question about low upload speeds in FF.
 
Okay I have figured out the issue. Don’t know exactly down to the technical aspects but basically My WiFi runs in 2.4GHz (802.11n only mode). If I am close to the router I get full speeds. Wheras if I’m away from the router, the speeds negotiated by my devices and the router get a 50% cut. I can see the negotiated max speeds getting lowered by 50% when I’m far from the router by logging into its UI. The funny thing is only the upload speeds take that 50% cut. Download speeds are unaffected.

As for my previous theory that the IP subnet might be the issue: each time I reset the router, I was physically close to the router and my devices registered a full bandwidth. So that was the confounding factor in the equation.
