LOL, okay that makes more sense and is easier to fix than a wired issue. Download inSSIDer from here: http://www.metageek.net/products/inssider/
Install it and run it like any Windows program and the pages show all the wireless signals and strengths that your computer can find. Anything on 2.4GHz (I assume you are not on 5GHz) like other networks, wireless phones, wireless speakers and headphones, etc. can affect your reception. You may be able to change to a better channel if the problem is other network signals on the same radio frequency -- an easy change in your router wireless configuration. Other issues can be the location of the computer relative to the AP broadcasting. The fastest way to kill a good connection is to turn on a microwave oven nearby as it also creates interference in the 2.4GHz range.
