Hi all,

I'm in a unique situation where my landlord can't log in to his router nor is around/cares to contact the ISP to do so. This is my current setup. Does anyone know how I might go about measuring the latency between the router and my end devices (area shaded in orange)? I'm just curious to see how much my setup is introducing in terms of online games and what not.

And yes, 40 mbps is all we get out in suburban Alaska. Cope with me.

Just ping it?

Actual traffic might be slightly different, but honestly on a LAN you shouldn't need to worry about latency. But you're not going to be able to run iperf3 on that router in any case.

Sounds good, I'll go ahead and just do this. Connect to landlord's router -> ping test -> connect to my router -> ping test. Thanks for the comment!

Or, you know, just ping your landlords router.

Also if the router blocks icmp for some reason you can always manually send an ARP request and check the response latency.

This is the answer. Although you may need to look up the IP address (a lot of them use 192.168.100.1) and you may need to reconfigure your gateway/firewall/router to route that subnet out its WAN interface while still performing NAT.

This is a cry for help haha, you poor soul

how long did it take you to upload this image?

[–] moonsnotreal@lemmy.blahaj.zone 10 points 10 months ago

About 30 seconds

Tracert will give you the latency of each hop required to make it to your destination. Not sure why everyone is complicating it.

[–] supercritical@lemmy.world 7 points 10 months ago

Thank you, this is exactly what I was looking for. I’ve found essentially less than 1ms of latency between my mini router and my landlord’s router and I’m very happy with that.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters
IP Internet Protocol
NAT Network Address Translation
VPN Virtual Private Network

3 acronyms in this thread; the most compressed thread commented on today has 10 acronyms.

If you want to test what your equipment is doing to your latency, connect your pc directly to your landlord's router, run latency tests multiple times, then set everything up as you normally would and run the same tests again. Some recommended tests for different situations would be fast.com for netflix/video streaming performance, and https://www.waveform.com/tools/bufferbloat for bufferbloat. Other things you'll want to check for gaming performance are double-NAT and ping tests for the online games you tend to play.

As a network engineer I use this frequently to figure out where latency is coming from. +1 for mtr

Do you physically have access to the router? If so, I would figure out the settings it uses that other people notice (wifi settings etc) and just hard reset it. Chances are they just use the basic settings provided anyway.

Is anybody else using the router or just you? If just you, I'd just do what you want to it and reset it when you leave.
