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, could that be affecting it?

 

Or could something inside the network be causing issues?

 

Any help would be really appreciated šŸ‘

 

Mike

 

P.s. it won't let me post.my think broadband link for the graph showing the packet loss.

Hi @MikeyG23 

Thanks for posting in our business forum.
If you have not changed anything recently, or ever since it was set up, that could be your ISP getting unstable recently.

 

If the bad packet is referring to the one from the EAP, you should post this on the EAP page. Not the router.

You should test more on the modem before concluding the problem is on the router.

  @Clive_A thanks for the reply.

 

It's not an AP issue as all my testing is done with hard wired cat6 connections. When I plugged directly into the modem and bypassed my internal network, the problem went away so it must be something my side of the modem.

 

Not sure how I go about troubleshooting from here really?

Hi @MikeyG23 

Thanks for posting in our business forum.
Start from the most basic steps:

1. Check if there is a network subnet conflict.

2. Run a 3ft cable from the modem to the router WAN.

3. Examine your DNS.

4. Follow this guide and use ping to test your local host to the gateway latency. See if you have any loss or high latency.

 

If you need me to see through your case, please upload your screenshots of the ping results.

 

Please mosaic your sensitive information. Here is a list of information considered sensitive:

1. Public IP address on your WAN if your WAN is.

2. Real MAC address of your device.

3. Your personal information including address, domain name, and credentials.

For troubleshooting purposes, when a WAN IP is needed, please leave some values visible for identification.

  @Clive_A Thank you for the information and the guide - really helpful.

 

So internal ping shows some variation, although not too bad;

 

Ping statistics for 192.168.0.1:
    Packets: Sent = 77, Received = 77, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 1ms, Maximum = 46ms, Average = 4ms
Control-C
^C

 

 

External ping has packet loss;

 

Ping statistics for 8.8.8.8:
    Packets: Sent = 84, Received = 78, Lost = 6 (7% loss),
Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 37ms, Average = 5ms
Control-C

 

I then did the next command and found the following; does this mean my IP is not what I thought, 212.132.198.244 but in fact 212.132.198.129?

 

C:\Users\MichaelGarrettG>tracert -w 300 bingcom

About the tracert and why it is not sending to your IP, you should look this up on Google. Google has a better explanation than me. This should be found in Windows official docs about CMD. So, I will not bother explaining this.

 

In your local network, it should not fluctuate that badly. Avg should be around 1-2 ms because it is a local network.

I'd recommend you check your Ethernet cable. Very likely to be a bad cable. You should check the cables from your router to the PC. Every cable matters.

Second, you should check if you have any loops. It also matters because the local ping to the gateway is not gonna be that high. Loop may be another cause.

Third, high bandwidth-consuming devices may be the perp, too. Check if you have anything using the huge bandwidth in your network.
