Also Facebook and Youtube are super slow... download speed on "Download Manager" goes to maximum 2mb/sec where as it should go upto 3.2mb/sec as i have 25Mbps connection

 

[shaheerk]

No.

But it usually gets fixed after a day itself.

 

[Engr Zain Raza]

yep somehow pings are back to normal and packet losses gone.

It's just how the internet works - there's not much you can do.

For example, you can go from Islamabad to Lahore either via the GT Road (which is a congested hot mess during the day) which will be shorter, or you could go via the motorway (which is a clean, smooth, faster, more reliable road despite taking a longer distance). PTCL usually uses the GT Road since it is suitable for general traffic and what-not, but you can use a VPN and say that you want to go to Lahore via Bhera (and not Gujar Khan).

Unless PTCL change something and they begin to prefer the motorway for their routes. Good luck convincing them to do that.

So, I searched about this issue quite extensively on Reddit and I found quite a few people having this issue. One of them solved it by reinstalling Windows and so did I. LOL! There might be some Windows update or any registry changes that caused this. I hope it doesn't back.

Anyone on PTCL GPON using OpenWRT SQM? I am using Archer C20 AC750 with the ZTE PTCL ONT in Double NAT. SQM works fine for the most part but the devices connected via WiFi seem to be a bit slow e.g. even the WhatsApp message sending is delayed by a second or two.

 

[manobilla]

just add your ptcl ont to DMZ of your OpenWrt router

What difference would that make? I have already forwarded the ports.

You won't be able to fully take advantage of SQM or any type of QoS because the PTCL ONT is still handling routing and traffic shaping after it leaves your router.

PTCL still doesn't offer bridge mode for FTTH so there's no way you can get around it. Enabling DMZ or forwarding ports will achieve nothing.

I see, but still enabling SQM has improved the latency stability drastically. Since, only the IPTV is connected to the ONT and rest of the devices are connected to the openwrt router so I think it works quite well.

but what about with torrents?
and whats your settings for SQM? can you please share

Everything was working fine including torrents. I have reverted back to PTCL ONT for now. As for the settings, I used piece of cake script with ingress and egress both set to 14000 (for my 15Mbps package). Rest was default.

whats the difference between speed test with and without SQM on PTCL server?

Download and upload speeds get reduced to 13Mbps.

 

[Engr Zain Raza]

Anyone facing super slow browsing and downloading?
on speedtest i am getting 4Mbps out of 25Mbps.
*Plus when i try to browse(load) a site my ping to 8.8.8.8(google dns) goes to 200ms from 47ms...

 

[Engr Zain Raza]

I don't know what is going on but after 6pm (Evening obviously) speed gets capped to 5Mbps on my 25Mbps connection...this is happening from i dont know how long but i did speed test yesterday after many months...So PTCL is probably doing this from 1-2 months because browsing has been pretty bad and i didnt bother to do a speed test simply because i am on VDSL2 with perfect line stats...

Same here. I'm using 50Mbps after 6 pm it drops down to 2-4 Mbps, facing this issue from last few days. But normally at night YouTube videos are always buffering and it's hard to watch even at 720p and sometimes even 144p videos doesn't load.

 

[shaheerk]

Are the speeds capped to 5Mbps or so on ALL speedtests (including PTCL servers)?

Since VDSL is dependent on copper, one theory is that there could be electromagnetic interference from someplace (electricity wires outside your house, or inside your house, or some appliance is turned on and the wires aren't shielded enough).

As in - the issue could be inside your home, outside on the street, or at PTCL's end.

Nah... problem is at backend they are sharing vdsl connection between 4-8 users
If memory serves i think it is called " contention ratio " where 4-8 connections(Vdsl users) are assigned a certain bandwidth like 40Mbps to 8 connections comprising of users from lowest package 8mbps upto 100mbps... now if you are unlucky and you got all 25mbps connections in that certain group then it means
25x8=200Mbps required to give full speed to each user but instead of assigning 200Mbps to group they assign 40Mbps or even less because of which speed peaks below 5mbps...
Tonight Speedtest at different time is below
6pm = 10Mbps
7pm = 5Mbps
8pm = 4.67Mbps
9pm = 3.6Mbps
10pm = 2.99Mbps
11pm = 1Mbps
After that i stopped testing... I believe we all PTCL users should keep speed in check and all these tests were done by having only 1 user connected through LAN cable. No wonder why i am facing slow browsing from last 2 months and i didnt even once bothered to test speed cuz my MSAG is new and its population is merely at 15% out of 100% capacity soo... its not possible that MSAG is overloaded.
It is unfair to charge 4700rs something for 25mbps and giving crap speed at the time when we need internet the most... Who needs full speed in morning when we are at work or after 3am when 99% of people are asleep...i am thinking about switching to some other ISP or making a complain to PTA...

 

[shaheerk]

That is indeed a consequence of a poor (high) contention ratio.

To rule out gateway problems, what if you do a speedtest from PTCL to PTCL's own testing server? Do you get similar results?

If not, then I don't think it's the contention ratio at fault but some other back end issue. But if you do get the same results, then you're all getting shafted by their bandwidth chokehold.

You can complain, or switch to fiber (touch wood, I haven't gotten any speed problems but customer service is another story... Prompt, in my case, but in the wrong direction), or switch to someone else.

I'm at the point where I've used Nayatel, but ended up with PTCL fiber cause there was no Nayatel, and now that they're digging up outside my house, I'm contemplating. I get 25Mbps with PTCL (constantly) and Nayatel has 20Mbps (I don't mind) - but the monthly costs will be different considering we also use the landline.

Damnit. Choked competition.

Thank You for detailed reply
Well i complained via facebook, twitter and 1236. and even though its pretty hard to believe but they fixed my speed somehow so far that is. At the moment i am getting full speed but lets see how it goes on till 12 mid night. And most importantly lets hope that i will keep getting full speed at peak hours.
Honestly i was not expecting a fix that fast xD though i am glad. Also apart from this i learned that all VDSL connections are dedicated and their bandwidth is not shared among group of people. So a VDSL user should get full speed 24/7.
