Really slow.

Expected Behavior

Everything was working just fine, then something happened. I think we had a power glitch (even though it has a UPS Hat). Anyway, the OMR router, which runs on a Pi4, reported a readonly file system.

I'm away at present so I have no way to create and install a replacement SD card. I fixed the file system as well as I could, and it is no longer readonly. I tried updating to the new version both on the VPS and on the router.

Current Behavior

The maximum down speed is 4Mb/sec.

The current wan connections are vDSL at 39.45Mb/sec, vDSL at 31Mb/sec and 4G at (maybe 30Mb/sec).

I tried going through each of the processes in system/startup and restarting them one by one. That seemed to solve the problem. I was then getting over 40 down, 20 up. But the next day it is back to 4 down, 1.5 up.

If I use the bypass feature to connect a specified lan IP through wan1: I get about 30 down, 8 up, as I would expect from that single connection.

Any suggestions about how I can work out that is wrong and fix it? No clues in the log.

Try these settings:

network->mptcp
Congestion Control: bbr2 (only if your raspberry supports 64bits)

system->openmptcprouter
wan(1,2,3) Enable sqm and set Download/Upload speed (Kb/s)

network->sqm
wan(1,2,3):
quee discipline: cake
Queue setup script: piece of cake

tun0:
quee discipline: cake
Queue setup script: piece of cake
link layer adaptation: None

[hairy-dog]

Sadly, that didn't seem to make an appreciable difference.
I think I shall need to set up a new SD card with the defaults and take it from there, but I can't do that remotely.

[duckigol]

could it be the ethernet cable
Your micro-sd must be at least class 10

[hairy-dog]

It's the same ethernet cable and microsd that were working brilliantly for more than a year. And the speed is reported as 1000mb/sec. I suspect it is a software setting derangement.

Check on VPS that the correct kernel is loaded via "uname -a"
Check also that all is green in OpenMPTCProuter status page
Check speed of interfaces using "omr-test-speed wan1" for each WAN interface you have, and "omr-test-speed" to check aggregated speed (ctrl+c to stop after 2 minutes). Run also "omr-test-speed" on the VPS.

Seems that you have a problem with wan5. What is the aggregated result when you disable MPTCP on this interface ?

Enabling MPTCP over VPN for that wan makes no difference

I tried speedtest.net just now and I got 27.38 down, 5.94 up. That's slower than wan1 on its own.

[Ysurac]

So there is a problem with wan5. As aggregated speed without it give wan1+wan3 speed
The "Operation timed out" is not good, and it's not MPTCP over VPN that can solve this. Check MTU and check if the connection is really working.

[hairy-dog]

Wan5 is reporting sync at 30 down, but it is a strange connection. Its status says:
Traffic Type:PTM
Line Rate - Upstream (Kbps):6690
Line Rate - Downstream (Kbps):30687
and it says
Network TypeMER but I have nno idea what that means.

Is there any way to reset all the settings to defaults without losing the essential settings in /cgi-bin/luci/admin/system/openmptcprouter ?

Because I'm working on this remotely, I can't just start again with a clean install.

[Ysurac]

No way to reset and keep some settings.
For me the problem is only on this wan5. What do you have in OpenMPTCProuter status page about this gateway ? detected as working or as down ?

[hairy-dog]

As a separate idea, I would find it really useful to have a way to simply set a few basic parameters in a text file: the details of the vps and the ip address settings of the router and the wan connections. Then have that file in the root of the sim card so when it boots, it picks those up. That would make installing much easier. I'm not sure how possible it would be to implement.

Back to the probem in hand:

The System / OpenMPTCProuter / status page shown all three wan connections as green, and the MPTCP support check brings back sender's key for all three, but now I am seeing VPN tunnel DOWN in amber in tbe router status section.

The Network / MPTCP / Bandwidth chart isn't showing the data that is flowing.

[hairy-dog]

I finally got home. Powered down the Pi. Fitted the backup copy of the microSD card, started it up.
Added a couple of new wan connections, and it worked beautifully. Then the autoupdate also worked well.
All fixed in five minutes.
