Question SW for monitoring home LAN

[marvinbower]

Is there a simple LAN bandwidth monitor ?
In other words I don't aim to trace every single packet.
My key goal is to see how my bandwidth is "splitted"
Over my wired and wireless home LAN , that has more than 30 devices
And see where are the bottlenecks

This would be most likely implemented in your router. Asus routers can do this, as can, I think, Tenda (newest ones), and of course, Tomato-firmware based routers.

Are you experiencing problems that would lead you to believe theres a bottleneck

 

[marvinbower]

my home LAN is very simple:
- 6 eth ports in 6 rooms with 10 devices attached
- about 20 wireless devices
sometimes part of those devices work full speed, very reactive, no lags whatsoever
part of them seems without hope, lagging and/or not responding at all

 

[VirtualLarry]

I would guesstimate that you would need a 200Mbit/s-300Mbit/s internet plan (or better) to be able to utilize all 10 wired and 20 wireless devices at once, potentially watching video. (That might not even be enough for 100% of your devices to stream video, probably need a 500Mbit/sec connection.)

You aren't "android farming" with those devices, are you?

Typical reaction for a system with too weak Internet connection for such a load, that might further slow down with VPN (if used)

It could be WAN speed related, possibly local device related. WiFi overwhelmed, interference, soho device overwhelmed. Really depends on your specific config and what's going on.

Basic tools like ping and traceroute can help find bottlenecks

So can more advanced tools like iperf

How to the Monitor the Bandwidth and Data Usage of Individual Devices on Your Network

How much bandwidth and data are the devices on your network using? Bandwidth hogs can slow down your entire network, and per-device data usage is important if your Internet service provider imposes a bandwidth cap.

Home router with custom firmware usually is still not powerful enough.

You probably need a firewall like pfSense with NTOP (NTOPNG) plug-in or something alike.

Problems experienced by OP can also be related to anything that ch33 has mentioned.

Easy way without a new router or installing anything--just unplug/disconnect everything else except the one device you're working on. And then just do this with every device on your network. It will take some time, but should help you figure out what you want.
