Inconsistent Transferrate

[Speakerator]

Hi @ all,

 

I need some input regarding possible starting points examining the following issue:

 

My LAN provides really inconsistent traffic - e.g. gaming and even surfing sometimes is impossible.

Example: playing something like the Culling / CS:GO gives me a Ping of ~ 20 - 30 ms on a 20 MBit outward connection (see level area in the center of the screen capture below)

From time to time (~5mins), traffic drops abruptly, resulting in seconds of lag when loading a webpage and pings above 500 ms. This happens on all devices on the network. Router is configured fine, nothing out of the ordinary.

Also occurs, when there's only a handful of devices connected and only a single on actively causing major traffic (e.g., me home alone, with PC and phone connected and PC stressing the network)

 

I am fairly new to debugging networks, so any input regarding potentials issues / starting points is appreciated. Already had a look at the traffic with Wireshark, shows nothing out of the ordinary (as far as I can judge, based on the knowledge of a few networking classes I took during my undergrads / grad studies). Despite testing with a different router (which I do not have on hand) - where should I start examining this?

 

 

Best regards

Chris

Don't trust task manager that much.

I do not trust it - this was simply to visualize the behavior I depicted - the "spikes" occuring, when traffic brought down. Any tool recommendation (despite Wireshark) for network (trafic) analysis?

Sorry, I can't help you that much.

How do you access the internet?

Your modem should give you information about the state of your line.

[Speakerator]

ISP is a German one, Unity Media, on a 20Mbit connection, standalone modem connected to the router. Despite maybe some inbound traffic keeping the router busy I doubt that it's due to the ISP or something external, since everything works like a charm, if you exclude the router and simply connect a single device directly to the modem.

So it is a connection over coax (EuroDocsis)?

These lines are shared by many people thus other can slowdown your connection.

I'd monitor ping times to internal and external IPs
