Testing a single Ethernet connection/Ethernet cable with Firewalla Gold
Hello everyone,
I am wondering if it is possible to test a single Ethernet cable/connection of my network with my Gold box.
It seems that the network performance bar across the app is measuring overall network performance and the measurements and the results are related to INTERNET performance.
I am attempting, with the help of my neighbor, who works in IT, to use iPerf3 to measure bandwidth and packet loss of a long Cat 7 cable I have run from my PC to my Stereo rig in my living room.
This program is a bit difficult to implement and use and requires a certain level of knowledge that makes this rather problematic at best and and useless at worst, so I am wondering if my Gold box can do the same thing.
If so, how would I isolate the cable /connection in question to be sure of measuring just this one section of my network. I do not need to be connected to the internet to to test this section of my network, and would I need to temporarily rearrange some cabling to do this testing?
Thanks,
Rob M.

I assume you want to measure the performance of the LAN side? you can use this https://help.firewalla.com/hc/en-us/articles/360056875493-Speed-test-and-Speed-Optimization-on-Firewalla
See the LAN test section. You can also do it over wifi using firewalla 1.50 release.

Actually, I want to test just one Ethernet cable, and then its possible replacement. I am looking for more than just speed, I am looking for bandwith as well as any potential packet loss.
The topic link in your reply was very informational, for example that all Firewall products can test connections.
I assume this a yes/no for the Firewalla box, and the related speed of the connection.
-
Yes I can. This is exactly what I hoped to do,but....
Will the test information be available to see/or record?
Were on the desktop UGI will I go?
And most importantly, can it measure more than speed?

Now I know this is not in the address bar, I put it there to screenshot it. I spent a couple hours trying to see if I could connect, but to no avail.
So,
1) Is this the correct format for this address?
2) MUST the cable to be tested be connected for Firewalla to connect?
This is what I get when I try this:****************************************************************************
Unable to connect
Firefox can’t establish a connection to the server at 70.15.99.147:8833.

If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access****************************************************************************************************************

No, so what you likely have there is your external IP address. What you want is the Firewalla internal address. To find that, open a command prompt (hit the windows logo and type CMD, it should come up, it's a black and white text window). Then in the command windows type ipconfig/all. It'll spit out info and you'll look for the line:
Default Gateway . . . . . . . . . : 10.10.0.1
That 10.10.0.1 is my Firewalla internal address, yours could be different, but will likely be 10.10.xx.xx.
You then use that to go to: http://10.10.0.1:8833/ss/ to run the tests. (don't forget the /ss/ too.)
Just dawned on me - if you know what you named your firewalla you can also just go to: http://firewalla.lan:8833/ss/ (mine is named firewalla so add .lan to it and you don't need the IP)
-
Ahhh, yes lol I used the IP address when I opened the app...
It worked correctly this time.
My question now is, how do I isolate the one cable in question? What part of my network was tested with this done thru my browser? I see a jitter result but I am looking for cable bandwidth and any packet loss. Can you convert the speed result to a bandwidth, or is speed the opposite side of the bandwidth coin. And jitter to packet loss?
-
If you plugged your laptop into the cable and the other end is plugged into Firewalla then you tested the cable. The bandwidth is the speed. The ports on your device and the Firewalla are 1GB, and you pretty much hit that with the upload/download speeds you have (1000MB = 1GB) you'll get variations, but if you're looking to see if a cable is bad this should work. The display doesn't have packet loss, but packet loss would slow down the transfer, Ping is just a quick send/receive round trip test (how fast can I get a response), and jitter is a test of how much variation there is in the response time.
-
Awesome, that works ! Some minor variations between the current cable and the possible replacement, and so re-ran the test a couple more times to be sure. To swap cables is gonna be a major pain and I needed to be sure there was no manufacturing defect that would show up as a intermittent problem.
Thanks to Rich T. for the support and good explanation's !
