Hi folks, i've been facing an issue let me explain. Currently i set up an edgerouter x as router, connected to a xiaomi dumb wifi access point with default firmware.
I also successfully configured the script for DSCP marking and it's working great.
But, intranet lan traffic has too many ping spikes. i've tried to ping my laptop from my phone, ping my phone from my router, ping my laptop from my router, all of these have completely unpredictable ping spikes, dancing from 3 to 100 ms. Has this something to do with my xiaomi dumb ap, or it could be something on the openwrt router that i need to change?
All of these pings were performed via wifi 5ghz which has no problems with internet latency, if i ping from my router to my ethernet pc, i get < 1 ms of latency, ideas? Thanks!
Edit: this is the ping between ethernet pc and wifi laptop, it seems like incremental, then it drops:
