Question Optic fiber packet loss?

[User1990]

Hey!
So I went to 1gbps up/down optic fiber from my 100/10 copper line yesterday and I've been noticing some packet loss.
In valorant for example I've been losing 80-100 packets per game.
Would these be enough to cause my game lag ?
Seems weird either way because I didn't have these issues with my 100/10 line.
Could my new ISP have different pathing or something?

Thanks!

Pathing likely to be different with any ISP on any given day. And generally outside of your and your ISP's control.

Update your post to include full system hardware specs and OS information.

Run "ipconfig /all" (without quotes) via the Command Prompt. You should be able to copy and paste the full results to post here.

I would first be interested in knowing what DNS Servers were and are being used.

Right now I've been trying google dns but still the same overall.

You have as fairly large loss in hop 2 which represents the connection to your house.

This is something your ISP needs to fix. Not sure what would cause loss on a fiber. Things like coax cable can get stuff like corrosion or water in connections fiber is pretty much immune to that.

Maybe there is a crack someplace in a fiber. The single fiber strand actually is connected to multiple houses between you and the ISP equipment at the far end of the fiber. It should be affecting multiple customers but 1% packet loss it not real noticeable unless you are playing online games.

In a way this is a best case since it tends to be the easiest to get the local connection fixed rather than something deep in a ISP network.

Not much I suspect you can do, maybe the modem shows signal levels but that would just confirm there was something off with the fiber connection. I would not do anything with the fiber it is extremely fragile just wrapping it around your finger can cause cracks.

Yeah I play online games and at high competitive level too.
Contacted my ISP and they told me that they will configure some settings and that my signal looks good.
They also told me to keep monitoring it and if it keeps happening, to send an email with pictures from the programms above.

I suspected something could've gone wrong with the installation of fiber, installation is brand new(happened yesterday).
It looks a bit better after I contacted my ISP, will keep monitoring it.

Having issues with fiber than I didn't have with copper is actually very sad.
I literally upgraded to have better internet for competitive games and I'm back to having packet loss.

Fiber really has little to no advantage over most copper solutions when it comes to games. You might get a very slight latency drop but it is not enough to make a difference in a game. Most games have artificial latency inserted so that people with lower latency connection do not have a advantage. Of course if the difference is over 100ms they can't fix that.
Games only use maybe 1mbps when you play and more bandwidth is just left unused.

The main difference would be you can download the game faster...not just because it is fiber but because the plan is faster.

In my case a 1gbit fiber connection cost less money than the lowest 300mbps plan from the cable company.

I went with 1gbps because it was the same price with 100/10 and when people were home I was lagging on 100/10 even with QOS routers and stuff.
Didn't expect a fiber connection to give me this kind of issues.

It also acts slow, if I use 100-200 mbps out of 1gbps the internet lags, is that normal ?
It literally feels like I'm on 100/10 without QOS router.

You need to remove any kind of QoS from the router when you have a fast internet connection.

Modern routers have a feature that allows the NAT function to be done in a hardware assist bypassing the CPU. When you use QoS the cpu must see every packet and now the cpu must also do the NAT function.

This is not so much a issue on a 100mbps connection but on faster connection the small cpu in the router can not keep up. Many routers cap out at maybe 300mbps with QoS on. QoS only applies if the router must choose which packet to send when there are multiple packet waiting to be send. You never should have packets waiting on a gigabit connection anyway...if you do then you need to ask why you are overloading such a large connection.

BUT that should not be your primary concern. You show packet loss to your house. Since this is a new install it likely is something they did not test properly. Hard to say can be as simple as finger print on the end of fiber. It does not take much to reduce the levels of light from the lasers. Packet loss, especially packet loss that occurs consistently, the ISP can fix.

I don't use QOS now, I meant it felt like when I used to have QOS on my 100/10 connection.
Well hopefully they do fix it.
They changed my private ipv4 address and I still had issues, so they started to suspect a faulty router.
They confirmed the issues themselves and I'm still waiting on a technician to come change the router and see where it leads.
