Internet problems

My Internet connection is very slow.
Many factors contribute to the speed with which you can surf the Internet. They include: network speed, network conditions, time of day (when everyone else is surfing, your access can be slow) and popularity of the sites you are trying to access. If accessing a particular site is very slow, try later.

Wireless networking problems
This section provides general troubleshooting tips for networking problems, specifically wireless (Wi-Fi) networking. The terms and concepts used assume a basic understanding of networks, and may be for more advanced users. If you need assistance or if you are not familiar with the terminology, please see Windows Help and Support or contact your computer technician.
If your computer is equipped with an internal Wi-Fi adapter, verify that the Wi-Fi antenna switch is on (the Wi-Fi light will be lit).
To determine if your computer has an internal Wi-Fi adapter, check the device list in Device Manager (part of the Windows Control Panel, Hardware and Sound). Some Toshiba models may have a Wi-Fi antenna switch even though they do not have an internal Wi-Fi adapter. Verify that signal strength is good using the utility provided with the Wi-Fi adapter. If another computer is on the same network, verify that it has network access, and can connect to the Internet. If, for example, the other computer cannot browse to a public Web site, the ISPs (Internet Service Provider) service may be disrupted. Verify that the Service Set Identifier (SSID), or network name, is correcti.e., that it matches the SSID assigned to the access point you are attempting to connect through. SSIDs are casesensitive. Toshiba provides a Client Manager utility for setting and managing SSIDs. Check the Control Panels Hardware and Sound Device Manager to verify that the Wi-Fi adapter is recognized by the Windows operating system, and that the driver is loaded. Carefully note any error messagesthese will be very helpful if you should confer with a support technician at a later time. Verify that the network connection is configured to obtain its Internet Protocol (IP) address dynamically: 5 Click Start, and then Network. Click View Status. Click Details. Verify that the DHCP Enabled setting is set to Yes. Click Close.
Use IPCONFIG to verify that the computer has a useful IP addressone other than the private address of 169.254.xxx.xxx assigned by Windows. 3 Click Start to open the Start menu. Type Cmd in the search field. At the top-left of the Start menu, click cmd.exe to open the command prompt.
