Lebara/Vodafone packet loss

Starting a new thread on Lebara/Vodafone packet loss as this seems to be real and possibly a long-running discussion. OPNsense Reporting -> Health -> Quality. Monitoring IP for Lebara via Teltonika RUTXR1 is 1.0.0.1 (static route automatically installed by RUTXR1).

Hi, i don't have any meaningful metrics to add, however in my experience vodafone has been pretty bad for months (if not longer) with packet loss. Compared with EE and Three which i also have access to the difference is easily noticeable when testing with my 5G router.

EE pings : 20-30ms
3 pings: 20-30ms
Vodafone: 20-80ms, frequent dropped packets.

It's also noticeable with voip/zoom/teams calls breaking up more often on vodafone.

@mikeliuk more details on your setup please
Teltonika RUTXR1 (Lebara SIM) -- OPNsense (WAN direct connection).

Other aspects shouldn't impact this as the 1.0.0.1 route should be as above.

There's a second gateway via Teltonika TRB500 which is load-balanced with the Lebara connection at the RUTXR1 (88 weighted EE, 1 weighted Lebara) but a static route for 1.0.0.1 via Lebara (reversing the weighting and checking with packetlosstest.com as the control that everything is as expected that Lebara is bad and EE is known-good).

OPNsense has 1.0.0.1 as the monitor IP (OPNsense WAN) for the RUTXR1, and monitor IP 8.8.8.8 (via OPNsense WAN2) for the TRB500 (I think this was to force the 8.8.8.8 route via the TRB500 as I usually want the primary DNS route to float so misremembered what I had implemented here).
 
Makes sense to have made a separate thread, good thinking. I'll add my notes/thoughts a bit later today.

View attachment 5748Not tried vodafone but lebara has so much packetloss 10-40% 5pm-11pm ive tried everything ping is good though i get 20-26ms even on a tower7km away but same issue packetloss contacted them after wasting my time for 30 minutes and then he says Whats packetloss?🤣
 
You attempted to alert anyone on Twitter at all, if you've already tried with CS themselves?

Ker Anderson seems quite active. Might be able to answer or advise.

Assuming this is a VF issue and not just Lebera...

I've been experiencing the same since late November. I've personally only used Lebara, but plenty of people on the VF support forums have also been complaining of a similar experience.

Since early January I've been in contact with someone internal on the VF network team; they're at the very least aware of the issue, and claim to be mitigating the issue week-by-week, but so far I've noticed little to no difference. Not heard back for probably a month now, and admittedly I haven't done much testing since.
 
We've now reached the appointed time for Lebara packet loss to spike for today.

Here is from the RUTXR1 RutOS/OpenWRT CLI (60 pings separated by 1 second as sub one second not possible):

Here is a nice picture (NOWTV streaming paused when I remembered to check for packet loss spike):

Recording asymmetry in the routing (number after "asymm") which I'll want to check when the packet loss finishes spiking:

I can only speak for today as I've not been using VF for the past 2-3 months, but the packet loss seems to have mostly vanished. I'm still getting the odd packet dropped (0.1% whereas Three is a consistent 0%), but it's much better. Hopefully this lasts for more than just today...

Wed 19th Apr was much better with under 8% packet loss but I think it's too early to call the issue gone as Tue 18th Apr was over 12% packet loss (peaking at 18.9%) during one of the expected bad periods.

Throwing in the delay chart as an indication of health. Start of data is when the gateway was re-enabled following renewal of allowance at midnight before that time.

Yeah, not fixed. It's been as high as 10% for me today, and seems to be much more intermittent and less of an issue, but anything real-time (ie. video games) are still noticeably impacted.

I'd like to believe they're at least slowly fixing it, but if I were to guess, I'd say network contention is just going down because customers are leaving.

Thought I'd join in the fun again kocs, this is my Lebara result.

Did you ever experience any packet loss with Lebara? I can only assume it's affecting specific regions, though I've not seen a geographical correlation. Seems really weird, but I'm baffled by the fact it's taking their network team over 5 months to resolve.
