I looked at both of your choices. A lot of people go crazy with the little antenna design or pretty wording. I can tell you that all you really need is just a basic router for what you are asking.
Some external drives allow ethernet.
Might not need to find a USB enabled router because some printers allow ethernet connections.
If you really want a good network setup, it starts with the actual foundation of it. A router is just a router unless you know what you are doing with it, honestly. I can make a junky router very secure if you push the right buttons.
Just find a wireless N router. I like Netgear because I know where everything is located. You might like Belkin. Pick one and just work with it. Also invest in a UPS battery backup for your modem and router if you are hardcore. You can get one from Walmart for about $40 dollars. If you power goes out, and you have your computer to a battery back up, you can still surf the web. I have 4 of them, but some cost more. In my house. 1 for my tv system, 1 for my internet, 1 for my computer (never put one on a printer), and one on my alarm clock and battery charges. Yeah the last one was me going crazy but I wont be late to work.
So my long answer is, most of them will work fine. Just work at getting them setup with MAC address filtering, and securing your router very well.
I am looking for the best wireless router I can find. I know that is a difficult statement but here is what I'm looking at. I live in an apartment (currently) with lots of networks (I have 2 already). I also have a lot of device that run on 2.4GHz (stereo, doors, etc). I do not need external drive features although it could be nice eventually. I want security and speed as well as coverage. I may buy a house soon and would like a good network there as well. I have been looking at the Belkin N+ (http://reviews.cnet.com/routers/belkin-n-wireless-router/4505-3319_7-33361546.html) and the Apple Extreme Base Station (http://reviews.cnet.com/wireless-access-points/apple-airport-extreme-base/4505-3265_7-32307438.html?tag=box4505)
Any assistance with this question or any other routers the users feel are better please let me know. Thanks for your time.
