/ Allowing for 200ms typical RTT from here to the US, to simulate satellite latency on your OpenWRT or similar Linux CPE, add 200ms to your LAN (wifi wlan0) and WAN (pppoe-wan) interfaces (i.e., adding 400ms to the RTT):

root at wndr3800:~# tc qdisc del dev pppoe-wan root
root at wndr3800:~# tc qdisc del dev wlan0 root
root at wndr3800:~# tc qdisc add dev pppoe-wan root netem delay 200ms
root at wndr3800:~# tc qdisc add dev wlan0 root netem delay 200ms


Actually you should add 300ms each way, the report was just measuring satellite RTT, not satellite + Internet RTT.
