Our COMPUTER is all run numerous sorts of home windows, exist utilities/sniffers that I can make use of to identify where the bandwidth is going?

If you aren't currently I 'd very advise a program such as Cacti (which can be made use of combined with ntop) to order the website traffic statistics from your buttons (and also with any luck your WAPs too). This can aid you select when and also where the website traffic is stemming.

In addition it will certainly additionally offer you an excellent feeling for the circulation of website traffic - and also abnormalities in website traffic often tend to attract attention in the charts a little bit greater than simply surfing logs.

Most cordless routers log MACs of the attaching WiFi cards, several additionally permit surveillance that is in fact attached. When it comes to smelling WiFi, the typical device is Kismet.

" Someone" describes a person not in fact accredited to utilize it, that is pirating your signal?


To shield your WiFi you need to take adhering to actions:

  1. hinder manuscript - kids (will not antagonize seasoned job - vehicle drivers):

    • Turn off your SSID broadcasting
    • Limit link just to offered checklist of MACs
    • Limit DHCP just to fixed MAC - > IP assigments
  2. make use of WPA2 (with EAP - PSK, usage arbitrary passphrase).

Your router likely has a means to show what customers are attached via it, perhaps as DHCP customers. That would certainly recognize that is attaching to your cordless router, although it would not always inform you that was utilizing your bandwidth.

Can you offer us even more information concerning your network arrangement? I can recommend 2 various strategies:

  1. Depending on the sort of cordless tool you have, you might have the ability to make use of a network monitoring application that makes use of SNMP to take down statistics from the AP. The majority of venture APs will certainly have a MIB table that tracks the checklist of linked customer, their signal top quality, and also the variety of bytes made use of. In a similar way, your router might have a MIB that tracks website traffic by IP address.

  2. You can make use of a wired website traffic sniffer (wireshark, etherpeek) to see the website traffic. Those devices can generally offer you a failure of website traffic by customer. You would certainly need to smell the website traffic prior to it strikes your router (if your router does NAT). You can make use of a center (though those are actually tough to locate nowadays) or activate port matching on a taken care of button. You can additionally make use of a cordless sniffer, yet if the network is encrypted, you'll simply get a suggestion of the quantity of website traffic from each customer, not where the website traffic is predestined.

Adding to Jon B is solution, I have actually additionally made use of ntop to get an excellent suggestion of where website traffic is going. I downloaded and install a Virtual Appliance to make it less complicated to set up.

Depending on the make and also version of the cordless accessibility point/switch you are making use of, Tomato could be simply what you desire. It gives a wonderful bandwidth monitor, to name a few points.

Additionally, a bit costly, yet it appears it would certainly do what you desire too.
