Seeing as I will have a new netbook within the next few days, I just remembered that I don't have a Wi-Fi enabled router.
My current network setup is a Belkin F5D5231-4 router that connects to an Ambit U10C018 cable modem. I have had no input on the hardware until now. In my house, there are four desktops and two consoles. One of the consoles can and will connect wireless-ly and the other is very rarely in use. Along with that, the fourth desktop goes weeks without usage, so a four-port should still suffice. Basically, I need a router that can offer a decent wi-fi connection through out a single-story house, connect four devices via ethernet and two wireless-ly, and work well with my current cable modem.
This is one that I just quickly found while browsing newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16833124412 (Put the wrong link at first. XD)
Not sure if that would be perfect for my needs or not, but just throwing out a start. I'd really appreciate further help. ^.^
Also, my isp subscription is 15Mb/s though when using their test I get a result of around 7Mb/s down and 1.6 up. 7Mb/s is definitely tolerable, but I'm just wondering if my current hardware could affect it.
With few exceptions, any router can work with any modem.
I'd get a router http://www.dd-wrt.com/wiki/index.php/Supported_Devices. DD-WRT can add a lot of nice features. Some new routers market open firmware compatibility as a selling point (and, at least to me, it is). I've been hearing great things about this bad boy: http://www.newegg.com/Product/Product.aspx?Item=N82E16833320038 Wireless N, Gigabit LAN, strong support for both DD-WRT and Tomato, and USB 2.0. Really, the only thing you could legitimately ask more for is 450 MBit on Wifi and dual-band (neither of which really matter to you -- with one or two wireless devices only, even if both are operating on LAN services they still can't even theoretically max out your throughput, and if they are operating on the Internet there isn't a chance in hell).
Also, if you already have the ethernet running to these computers and consoles then you already have the hardest work done. Just get a switch to extend your router's ports. The only advantage for Wifi is you don't have to run cables -- if that has already been done, then you're just kicking yourself if you use Wifi.
Edit: Also, I'd avoid anything with internal antenna. There are things you can do to your wifi router to direct/boost the signal when there are external antenna, but not internal ones (at least not easily/simply)
And as to your question about your download speed: A lot of things can slow down your traffic. Depending on how the ISP operates in your area, other local users can slow down your connection if using a lot of bandwidth. It's also possible some other device was using the Internet at the time of your test: ISPs provide your house with a set limit, which then gets split between your devices on-demand by your router. Run the test again at night when no one else is online and see if it improves.
Edit2: BTW: 2/4 reviews say the recertification on that netbook isn't good.
