What traces does a pc connecting to a wireless network leaves ?

That depends on the infrastructure behind the network and what the network admins have chosen to track and log. On a well managed network, only the admin and authorized individuals would ever be able to view this information.

Any of the following would be possible:

-Your network adapter's MAC address

-Your computer's name

-Any websites you visited

-The amount of bandwidth you used

-Any other traffic you generated

-And much more...

Not that your average home network user would bother or even know how to review all that, but it's certainly not impossible.

It leaves its' MAC address in the router log files. part form that the ISP is legally obliged to store all traffic from each client for 2 years, and this would keep the packet identifiers for each machine and the sites visited. Most now store for MUCH longer. It is VERY easy for a legal authority like police to set a trap for a known machine so that whenever it next appears on the Internet a local force can reach the place it is connecting very fast. How else do you think they regularly catch and imprison serious criminals who know all the tricks and move around all the time?

the same traces a hard wired connection can be found.

usually, you can track these activities by IP addresses. usually listed as such:

examples:

192.168.1.1

123.456.789.1011

127.0.0.1

and that's pretty much it. Usually, there are hubs, or bases out there to log information on where this data goes. Even routers can do this~
