Setting up your wireless network for home or office is pretty inexpensive these days.  If you need a replacement router or a new one check out this online deal from Tigerdirect.  you can get a TRENDnet wireless G Router (4 ports) for only $19.99.  Almost half price.   A TRENDnet USB wireless Network adapter, also 802.11g and USB 2.0 is only $14.99.  I’ve never used the TRENDnet network adapter but the TRENDnet Wireless router is a piece of cake to setup and they work great.  Tigerdirect always has great daily online deals.  I like to check daily and pick out the hot deals.
I also like the Kingston 16GB DataTraveler 120 USB 2.0 Flash Drive they have on sale for for $25.99.
