Re: [nznog] Comcom/Samknows broadband testing from a different perspective

Hi Since putting the device on the Enable Network, I’m actually not overall happy with the results I'm seeing. There is an inconsistency with the Download/Upload Speed, Latency and Jitter. When testing using another Testing service such as Speedtest.net and Fast.com, Iperf are consistently report my connection speed as 950Mb/s Downstream and 500Mb/s upstream. Samknows is reporting this My peak connection Speed for download of 742Mbp/s and upload 429Mbps, but these results are not consistent when I compare other speedtest services. According to the data provided from Samknows user analytics, they are testing the download speed on the hour between 6 pm and 11 am daily and one sample at 5 am. These times represent Enable network peak and off periods for traffic. * The graph below are taken over a 7days period, sampling every 30 seconds at a bit per second. * Have another member of NZNOC got similar testing results to mine * What I can’t answer is how the data in the graphs below is represented by Samknows. Note: The Samknows device is the only (Connection) plugged into this GPON interface. There is other user traffic been generated on this port other than samknows device.

There is a Geekzone thread that I kicked off when I attended the Commerce Commission presentation about Samknows and got to meet Sam.

https://www.geekzone.co.nz/forums.asp?forumid=49&topicid=237852

I've done a bit of analysis on the traffic but haven't dug too deep yet as I didn't want to bust open the box and try and reverse engineer their OpenWRT build.

Happy to put anyone in touch with the guys I have dealt with directly from the Comcom and Samknows too.

Hi Brian,

You should call their support if you think there’s something going on that’s impacting your connection.

They will detect if your connection is in use and doing more than (I think) 64kbit/s in the last 30s or something, and won’t run the tests.

They have some clever stuff to detect if your wifi is in use, without being connected to your network and without being your AP. Perhaps that’s playing up?

Pretty sure it’s publicly documented, check out the links in that original post and if not we can dig up some other stuff I’m sure.

Hi all,

Longtime listener; first time caller.

I signed up to SamKnows (partly out of curiosity and partly so I can have hard data about my connection that I pay for) at home.

Over the last week my connection has gone from slightly adequate with the occasional drop out to a slow connection with regular drop outs.

Netflix and YouTube are stuttering, video games drop connection, and websites hang at random times.

I can't help but think that the email shared by Dylan sheds some light on why that maybe.

This programme won't be terribly successful if everyone gets sick of having a terrible connection during peak hours and shuts the white box down.

Pretty frustrating.

Brian
