Weird issue with WAN latency graph on dashboard widget, ER7206 v2 2.2.0
Weird issue with WAN latency graph on dashboard widget, ER7206 v2 2.2.0

Got a strange one with my WAN traffic graph, dashboard widget ("ISP Load") on my ER7206 v2 running 2.2.0 latest
The graph constantly reports a WAN latency of 1ms, completely flat
Echo server is ON, and tried both Auto and an external IP
Online detection is active, set to 5 minutes
I do not see this problem with ER8411 (on the now revoked 1.3.0) or ER605v2 on 2.3.0 and the same setting on those sites.
OC300 5.15.20.38
I factory reset and re-adopted the router a couple days ago to see if that cleared it and it did not, also factory reset the controller and restored backup, no change
I dont have any issue with WAN connectivity on the router, its jsut this graph that is acting up

I also tried something else today
Im in the UK, and i found some small hosting company in brazil, found their public IP, and set that as my echo server. Same 1ms for the whole time i had that set which is definitely wrong! Real ping times to them were in the hundreds of miliseconds

FYI, I reposted the bug here : https://community.tp-link.com/en/business/forum/topic/818848
Seems this bug will have a fix in next firmware.
