This really depends on what speeds you're getting through your Cable Connection.
If you're getting 100mbit+ I'd first make sure you have the right wireless hardware in your PC. Ethernet connections are faster than most wireless connections. If you hook something up like the ASUS AC66 Wireless Adapter (http://www.asus.com/Networking/PCEAC66/) you'll benefit from speeds of up to 1.3Gbits not only that but it's also using 5Ghz frequencies for less interruptions from other devices such as Microwaves and 2.4GHz Devices.
The other thing you need to make sure of is that your Modem/Router is fast enough. Obviously to take advantage of these speeds and durable connection you'd need a decent router. I'd also recommend ASUS products for this too. for example this

But this all really depends on how fast your Cable Connection is, and how important it is to you. If you just want to have a basic wireless connection
configure the Modem/Router by simply enabling Wireless in the settings and encrypting your connection with a Password.
To get to your modems settings, go to http://192.168.2.1/ Login with the Username and Password and navigate to the connection settings. You may need to roam around there for a bit to find the settings, I'm not familiar with Belkin, Although I'm quite sure that the IP I’ve given you is correct.
Hope this helps. Your question was pretty plain so it's a little hard to understand exactly what you were asking.
