Monitoring traffic in my home network

Posted on

QUESTION :

I have a very irritating smart phone which is auto connecting to the Internet. The phone itself does not have any network monitoring tools so there’s no way I can figure out which program on the phone is requesting the connection to be switched on.

I’ve reconfigured the connections on the phone to connect to my home wi-fi network by default. Is there a way I monitor its network usage?

My network setup is something like this –

My desktop is connected to the DSL router over ethernet, but other mobile devices connect over the WiFi. All devices/computers are in the same subnet and are visible to each other.

Any suggestions (monitoring tools for Win7) would be welcome.

ANSWER :

1. Disable wifi on the smartphone

My iPhone does this sometimes, and it’s really annoying. This isn’t a direct answer to your question but a workaround. Disabling wifi would help.

2. Install custom firmware on your router

dd-wrt is an alternate firmware for your router. It will allow for increased functionality and some extra tools (including a bandwidth analyzer) on the router itself. Just make sure your router is supported. If it isn’t, there are other firmware options available.

note: the downfall of using software to monitor your bandwidth is that it needs to be running 100% of the time (no downtime) to accurately measure the amount of bandwidth. Because of this, it just isn’t a good idea to use a software solution, unless you have a great reason to do so.

My favorite tool is Wireshark. It will allow you to monitor every single packet that goes through your setup.
