Re: Here's an answer, maybe
My old version of Norton had a feature to look at the 'puters on our network, but not statistics of use.
I seached the Lifehacker site and came up with these two articles. I've never used the programs mentioned, but they might help you out.
We used to have a mix of router connections here, but I got so tired of resetting the wireless every week that I ran cable to the other main computer and don't use the wirelss at all anymore.
Our decent speed here might be a result of only having a hundred feet of coax from the nearest fiber optic cable.
