Wireless Network Question

Again, I just got a Hog4 Love it,
Hog4 1.2.540b
But I want to set up a wireless network, I got two kicking Mac Pro's but they don't seem to do that grate on Hog4 PC so I found a fairly cool HP laptop on E,bay and I plan to run Light Converse and Hog4pc on it + OSC iPad.

So can anyone recommend and wireless router I have an Apple Airport Express
in my house and I was wondering about getting another one for the Hog4
