Bought anything electrical lately?
Cordless phones, new tv etc.?
If not most likely culprit is either router or lappy wireless card, try connecting via cable (they look like a modem plug but slightly larger, if that's the same then it's probably time for a new router.

Failing that buy one and return it if it doesn't solve the problem
