Greetings,
I am using a new Turris omnia wifi6 running Turris OS 6.0.3. Before submitting this report I factory reset the device so it is completely pristine.
I have the WAN port connected to a cable modem. There is a single device plugged into lan1 just for ssh access. No wifi is enabled, no other devices are connected.
If I run a ping to seemingly anywhere on the internet from the omnia then I see packet loss of 3-5%. With a ping interval of 0.1 the dropouts are always perfectly clustered in either 9 or 10 packet sequences so it seems there is something which causes all network to drop out for almost exactly a second. The space between dropouts isn’t predictable but it’s typically at least once every 20 seconds or so.
If I run a ping between the lan device and the router I don’t see any dropouts so It’s just the wan interface that is affected.
Here is a visualization using prettyping which nicely shows the clusters I’m talking about.
This one is to cloudflare but I have plenty of other similar results to google and various other places, it seems to reproduce everywhere.
If I connect directly to my cable modem then I can not reproduce these results, have successfully run a ping for 20 mins with no packet loss.
I have tried replacing the cable between omnia and cable modem with a brand new one, no change.
I have run a traceroute / mtr but as best as I can tell this doesn’t tell me much. As I know there is no problem when I connect directly to the modem I can be pretty confident the problem is not upstream anyway.
So I have an issue which seems to be caused by the omnia, I can easily reproduce it locally using ping but I don’t really have any idea of what to check next, any suggestions? Does this one second thing trigger any ideas?
It’s causing basically unacceptable dropouts in video calls which I do all day long for my job so I need to do something, all suggestions gratefully recieved.
Thanks
