After such service pack updates, you may need to reinstall the wireless adapters driver.. And sometimes, you may need to visit the adapter manufacturer's website to download and install and UPDATED driver.
2. Made sure the wireless adapter is turned ON? (Usually there's a button or switch on the laptop which turns the wireless adapter on or off.. Make sure it's in the "ON" position.
