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.
Clarification
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.
Ping statistics for ________________: Packets: Sent = 100, Received = 100, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 1ms, Maximum = 5ms, Average = 1msSo if I understand this, there is barely any latency being introduced here.
Yes, why would expect otherwise?
Unless you’ve got signal issues, wifi doesn’t add more than a few ms
Because I know very little about network and is why I’m seeking help/input. Thank you for your input.
Radio waves travel at close to the speed of light. Latency generally just comes from raw distance, unless the packets are being processed by a slow / overloaded device on route.
If the wifi has to retry a lot due to noise or low signal you’ll see loss and latency spikes, but otherwise its very little.
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.
Also if the router blocks icmp for some reason you can always manually send an ARP request and check the response latency.
