Very slow routing?

Turris Omnia
1

I just setup the Omnia and I’m seeing extremely slow speeds when using the internet. With my old router I was seeing 60 Mbps+ on typical speed tests, now I’m seeing <0.25 Mbps.

I tried raising the wondershaper limits (they were very low to start) but it didn’t help. I also tried uninstalling wondershaper altogether also with no improvement.

I only see one drop in the port stats:

The CPU is sitting at 0% and only 10% RAM usage.

Other output that I thought might be useful:

Edit: I just did an experiment and this appears to be a problem when I’m plugged into LAN3. LAN1 is fine, as so is wifi. I’m going to try all the LAN ports to see if I can find a pattern.

Edit 2: It is only an issue for LAN3. All the other LAN ports are fine. It’s very strange. I don’t see anything physically wrong with the RJ 45 port or anything.

I do see some L2 errors on the PC when going over LAN3:

Hello,
I think you misconfigured wondershaper, so first try restart router and when it doesn’t help, you should do factory reset.

3

Why would a misconfigured wondershaper only affect traffic on LAN3?

Regardless I removed wondershaper entirely and rebooted, but had the same issue. The tc command output seems to indicate that it’s indeed not configuring any shaping on the interfaces (AFAIK wondershaper is just a wrapper for configuring the kernel’s QoS parameters).

4

I’m seeing this too on all LAN ports. Horrible slow, .2 Mb/s throughput. Trying a reset now.

5

Hit the reset button and rebooted. Changed no configs. Now seeing ~950 Mb/s (Gigabit ISP).

I ran into something similar after the router was up for 4 days… download speeds were < 150kbps but upload was 800Mbps… Rebooting the router fixed it.
