It will require that you install the free firmware update from Merlin to allow the track data by device feature.
I'm going to let BirdDog guide you on that one as I believe he has that router.
Remember, he is kinda old
Phyllis,
To be honest, I wouldn't really be the one to give advice about routers, as my experience and knowledge of them is limited. With that said, as long as the router is working properly, and not taking into account the increased number of things that can be done with a more expensive router, they will all pretty much give the same level of basic service. I'm sure that the performance of my $40 Netgear router is just as good as a $300 router. But, like mentioned, I'm not able to see many of the more technical aspects that could be seen with a more expensive one, and the router like yorkytime bought has additional capabilities of being able to monitor data usage with a special type of firmware.
If the speeds you get wirelessly with your Linksys are about the same as what you get when your computer is connected directly to the modem with a cable, and your Linksys has enough range for your home, it's most likely just fine for your purposes and a more expensive router wouldn't be much of an advantage for you. This is just my opinion, of course.
Edit:
I should add that the Netgear router I'm referring to I no longer use much because it started going a little buggy a few months ago, so I have another one, but it's an inexpensive one, as well, and it works just as well as the Netgear did before it started getting buggy.
