It's up and running but with some interesting results.
My Onestream FTTC is 12/1 at best. ::)
4G Only - ;D

4G/FTTC 90/10 Split - Upload speed takes a dive :(

It's not immediately obvious what you are trying to show. As far as I can see, the second and third images are identical. Also, they show a 4G/FTTC split of 90/10, not 80/20.
Puzzled. ???

Sorry, never checked after posting ;D
My upload speed takes a dive when using load balancing.
-
Now it's clear. Thank you. :)
So it seems as if you would be better off not load-balancing but just keeping the 4G service as failover.
The above nonsense has been struck out. (Not thinking straight, today. ::) )

But 4G only has an upload of 32.
I'm curious what the overall speed of a Linux ISO download would be over http or torrent from distrowatch.com

I seem to be connected to 4G LTE-A now, pretty sure I wasn’t earlier. A quick google suggest it’s 4.5G….. ???
Currently on a 70/30 load balance, looks like it’s sorted itself out.
Seems to be a small improvement on my 12/1 FTTC. :cool:

Give me some quick instructions and I’ll give it a go.

Its worth ignoring the upload rating, as 99% of the time uploads are only single threaded so will randomly hit one or the other connection, unless you have the ability to do policy routing to force it over the faster connection. This was particularly annoying when I had VDSL, 4G Vodafone and 5G Three. As Three has the least upload, Vodafone had the most, but Three was about five times faster than Vodafone for downloads.
Downloads should easily max both if using a multi-threaded downloader, though I found it gets a bit more rough the more the different connections speeds differ. I also found it was easier to max out two WANs than three, and four would not seem to max out. Likely the same thing, as all four connections were of different speeds so it gets harder to evenly balance.
-
Thanks for the reply. Can you expand on 4 connections?
Im blown away by the speed.

The basic problem is that balancing is generally round robin (the router will assign a connection to the next WAN in the list, then the next, looping through the list constantly), so the more WAN connections you have, the more likely it will be unevenly loaded, especially when they're all different speeds. Of course this also depends on if single-thread throughput will just hit max, then it should just work, but especially on mobile networks that's not a given.
In pfSense I did have weighting, that basically changes the allocation so the faster connection is say 5x more likely to get used than the slower one, but you still can't account for the fact that's not based on a given client on the LAN, its just how it allocates traffic over the WHOLE LAN when a new connection is requested. So when trying to test the full speed, you wont necessarily get the allocation you expect as you add more WANs.
Plus different speedtests use a different number of connections, so you wont necessarily get the ideal number of connections to each WAN to max it out. It becomes somewhat pointless given real-world downloads will be either a single connection, or maybe 4 for downloaders like Steam. (I really should check how many it REALLY uses)
So it seems to work really well with 2 WANs, pretty good with 3, somewhere along the line 4 just caused an in-balance where I couldn't get all four to max out on a test. Of course 4 WANs is pretty extreme and it was just while I was testing the best combination to stick with, when my second DSL line contract was coming to an end so I was trying a few different mobile plans to see if they were sufficiently stable to replace it.
My original plan was once I got FTTP to have that and two mobile plans, one which stays at home as a backup, one which I could unplug and take with me when I go to meetups, I could pick which one based on coverage of the network where I would be going. But as the Pandemic never actually ended, I don't go anywhere so it became moot.

EE supports Upload Carrier Aggregation.
Those are impressive speeds, if you downloaded http://releases.ubuntu.com/22.04.1/ubuntu-22.04.1-desktop-amd64.iso what's your overall speed on the download?

I’ll try this tonight when I get to the laptop. :)

ipv6 passthrough is detailed here:
https://support.zyxel.eu/hc/en-us/articles/360021412820-NR7101-How-to-set-bridge-mode-cellular-IP-passthrough-
it should be just setting PDP type as IPV4/IPV6, though I have no idea how the RT2600 would handle that.

Interesting that Openwrt has been installed on it.

:thumbs: I'll have a play tonight.
