Are these pings normal?

Finally I have an FTTH connection and I just setup the network and I want to be sure that everything is fine or not. So I did some test and I see some differences.

First I directly connected to the network. That means:
ONT > Cat6 > PC
After this my ping was around 0-1ms. No peaks. Average was 3ms.

Then added Asus RT-AC58U:
ONT > Cat6 > Asus RT-AC58U > Cat > PC
The pings are around 1-2ms but I see some peaks and not clear why.

I'm not a professional but I know that more layer/distance cause higher latency. Also quality means a lot. But I have well shielded cables and the distance between the devices is less than 2 metres.

So are those pings/peaks normal? What could cause those peaks if the PC just idle and this is the only connected device while I test? Do I have to care about these or not?

Something wrong.
You are using the same 'duct' for energy/power and data?

15 meters - Cat 5 - 'home made' crimped cable - brand name "Chicken"; yeah! LOL China cable named Chicken. :lol: I brought a box/bulk on rush. 07/10 quality. (Unshielded )

That would make me wonder what's wrong. Ping to IP 193.239.149.210 max 22 ms seems to me perfectly fine.

I confused ip "193.239.149.210 " with one Class C. Sorry. :oops:

Ignore what I said.

forget the IP. it's relevant only for me. it's the local backbone. i'm talking about the peaks what appears while i'm connecting through the Asus router.

Those peaks in ms can be CPU work (NAT, ...) so I see it cool ;) .

I'd say these peaks a bit too high to be cool.
For me it looks really strange.
