Packet Loss (from router)

Hi all,

Looking for some advice if there is anyone who can help?

Been getting lag on playstation and on video calls the last few days. I set up a monitor as I assumed something was wrong with the network and it showed bad packet loss.

However, as a test, I plugged the playstation directly into the modem and connection was perfect so I now think the issue is the router.

Setup is as follows and hasn't changed since this issue.

Community fibre 1GB package
Adtran modem provided
TP Link ER7206
TP link TL-SG2428P
TP link oc200
3x TP link APs

Could the router be causing it? I'm running about 5 VLANS.
Or could something inside the network be causing issues?

Any help would be really appreciated 👍

It looks like you eliminated
TP Link ER7206
TP link TL-SG2428P
TP link oc200
3x TP link APs
from your network in your test

So as much as we can say is that the culprit is likely to be in that list. My next test would be to use the router but leave the rest disconnected and out of play.

Which IP address are you running the BQM to? You can edit out half of it if you want, but that graph looks like an IPv6 target inside your LAN.

Thanks for the reply.

I'm running it to 212.132.198.244 which I believe is my external IP.

I've read recently that community fibre use CGNAT - hence no port forwarding works for me - wonder if this has anything to do with why my IP my may incorrect?

When I check the IP online / and on omada it shows external IP as this thought?

I will try this shortly, but I wonder if I will get any connection from the router as it won't be assigning IPs (I think) unless I change the set up?

Mike

Obvs you need an IP address from somewhere. I would think that the router should provide DHCP because it would be unusual for the LAN side of a router to be a DHCP client. If the router is not supplying the IP address, you need to reconfigure. But in the first instance, it worked plugging the playstation into the modem, so how were the IP addresses set up? So try the playstation into the router and see what happens. if something else is providing the IP address, then put that back in the mix.

One of the things to consider as you seem not entirely clear on how your IP addressing is done is whether you might have 2 DHCPs running

If you can plug straight into the Community Fibre ONT with no issues then I'd say this problem is internal to your network - perhaps a switch loop or something similar.

Hi All,

So I actually don't think plugging into the ONT did completely solve the problem - I think it just so happened that the problem improved slightly.

The reason I say this is I am still getting poor connection (albeit, not as bad) and the broadband quality monitor shows fairly serve packet loss.

Is there any way the broadband quality monitor could be wrong?

Broadband quality monitor

Foolish me... I assumed on my original ping tests to gateway that I was plugged into the network. I had unplugged the cat6 and therefore was running via WiFi AP.

Internal network now confirmed OK, testing multiple outlets on the property on various VLANs and all hitting 1/2ms.

So definitely an issue externally / with the broadband provider I guess.

What is responding to ICMP for the BQM on your network?

I'm not 100% sure I understand the question but assume it's my router?

Mike

If you are on Community Fibre it's likely their CGNAT gateway or it's an IPv6 target inside your LAN. If I access the BQM creation page on a network that has IPv6 available then it defaults to using that address.

What is listed in the "host" column in the BQM overview page? Is it a long address with a mixture of numbers and letters in, or is it a short address with numbers only?

If it's numbers only, does it match the address that your router thinks is its WAN IP?

I think it's 212.132.198.244 although looks like the monitor is now not working as showing 100% packet loss?

So it's now changed to - 212.132.198.209
