Driver for WAN Miniport Network Monitor???

[macx]

Just what the heck is that?

Friends of mine all of a sudden can't hook up to the internet,
they're just on phone line.

There's a yellow thing by that WAN Miniport thing in their device mgr.

I tried to download a driver for that on my pc, but every site I visited
said I had to use IE (I use FF), then when I turned THAT on, it would only
let me update Win & IE, over and over and over.

Just what the HECK is this all about!?

I tried to find the driver on their XP disc, no go.

Should I uninstall and reinstall it?

Or is it something they don't want at all and I should just
uninstall or delete it?

Thanks!
