My wireless Internet connection stops working sometimes

This is usually caused by interference. Two common sources are 2.4GHz "remote"
telephones and microwave ovens. If you cannot remove the interfering product, try using a
different channel or setting Protected Mode.

I can get on the Internet, but everything is slow

If the Web site you are visiting is very popular, that site may be having trouble servicing all
the requests. If other sites download quickly, wait for a few minutes and try again. Usage
during peak hours may also affect the connection speed.
Other communications on the LAN, or interference with wireless connections, may slow
down the connection.
