I have a corporate client who lives in a whacking great house in North London. About two years ago I installed a Netgear router for the broadband connection. At the time the family had only two machines that were not too far from the router,and things were fine.
Now, all three sons have laptops in their rooms, there's a PC in the basement, and the client's wife brings a laptop home from work. The NetGear just wasn't up to the job anymore,and everyone was complaining about flaky connections, so a couple of months ago back I went with one of these NetGear Rangemax routers. The result was dramatic, all machines suddenly had very strong signals, and I haven't heard a word of complaint since.
