Latency increase after changing to router mode - Hub 5

I am rearranging some wiring and I have noticed latency double since switching hub 5 to router mode:

Immediately before switching to router mode (using edgerouter ER Pro 8):

Any ideas?

Difficult to know without more extensive tests but there's something very odd going on there. 

Have you run BQM for a while in each mode with just one device connected by ethernet. Leaving your own router out of the equation.

Thanks. Any specific tests you would suggest?

The VM test tool reports no issues.

I was running in modem mode, I then did a pinhole reset and now running it in router mode. I have about 10 clients attached, 4 on ethernet and the rest on wifi. Nothing fancy!

You need to run for a few hours with everything removed except one ethernet device. Overnight if that's easiest. Are you running two BQMs, one for each WAN IP?

I'm running one BWM, I just updated the IP address when I switched it to router mode.

So are you suggesting I disable WiFi and just leave one device attached on ethernet?

What does that test look to prove?

Thanks

It looks like rate limiting QoS/BWM

I suggest modem mode with a PC allow ICMP with BQM under a new IP

It suggests to me that there are problems outside your own internal network.

or you can setup a new BQM for VM WAN gateway and see if thats flat

Ah ok I might do that for the gateway IP, interesting

So I didn't do anything as I have been busy, and it seems to have sorted itself out. I wonder if it was network congestion or "settling down" (is that a thing) since I got a new IP address when I switched over to router mode.

Weird.

Glad to hear some of the advice has helped roodles.

How did you get on with this, is everything now okay?
