Network discovery takes very long time

I have tried to change DNS settings on NEBULA "From ISP" to "static" and entered 8.8.8.8. And turned IPv6 off as ISP apparently do not provide a IPv6 DNS server
Rebooted router
DNS1 and 2 still comes from ISP.
So I'm apparently not allowed to change DNS setting.

I managed to changed it to use google dns (8.8.8.8 and 8.8.4.4) as DNS serviceC:\Users\NilsB>nslookup 3.dkServer: dns.googleAddress: 8.8.8.8Non-authoritative answer:Name: 3.dkAddresses: 2a02:aa0:28:a000::100780.251.200.7C:\Users\NilsB>tracert google.comTracing route to google.com [142.250.74.174]over a maximum of 30 hops:1 2 ms 1 ms 1 ms 192.168.1.12 * * * Request timed out.3 18 ms 11 ms 10 ms 10.66.201.14 24 ms 12 ms 10 ms 10.66.199.15 32 ms 11 ms 11 ms 10.66.201.1706 26 ms 12 ms 12 ms 95.209.204.252.bredband.tre.se [95.209.204.252]7 35 ms 25 ms 25 ms 10.66.190.98 29 ms 21 ms 27 ms 142.250.164.1309 35 ms 21 ms 22 ms 142.250.213.18110 26 ms 19 ms 20 ms 142.251.236.7111 27 ms 19 ms 20 ms arn11s12-in-f14.1e100.net [142.250.74.174]Trace complete.C:\Users\NilsB>0

Just tested the speed.
Server discovery for speedtest on my phone is less that 1 sec. Download speed > 1Gb
Server Discovery for speedtest on WiFi6/1.2Gb connection to Nebula > 15 sec. Download speed < 200Mb
Nebula and phone connected to same 5G cell on same network from same carrier.
CPU power on phone and Nebula probably comparable.
There's something blocking the Nebula. Bad antenna? Not likely as that wouldn't delay server discovery but only download speed.
Any ideas?0 -
Hi @Bigtroll001
Noted, thanks for the information.
The symptom shows the bottleneck is from NR5101 gateway to the internet even settings changed, then we’ll need to collect debug logs on NR5101 to investigate. Could you provide your Org/Site name for us and enable the Zyxel support at Help > Support request > Invite Zyxel support as administrator, save the changes for us to check?
Thank you
Regards,
Bella
