Welcome to the World of Wireless!! lol
To answer your question, yes there are things that can interfere with the wireless signal in just the way you described. Some cordless phones, certain lamps set to close to the router, the structure of your home and sometimes the router is just a piece of crap. The easiest thing to try is switching the channel your wireless signal is on. You may also have to change the setting on the wireless card in your PC, normally its set to auto so its no biggie. The other easy thing to do is update the driver on your wireless card.
Go to Device manager -> click the + beside Network adapters -> right click on your wireless card -> click Update driver. If that doesn't work go to the maker of the laptop, get the latest driver for the wireless and manually update it.
Just out of curiosity, what is the make and model of the modem and/or router? If its one unit give us that. If its separate give us both please. =)
Hope this helps
