First try to determine whether you can connect to the Internet loadTOCNode(2, 'workaround'); You should first try to determine whether you can connect to the Internet. If you can connect, the error message is obviously incorrect. If that is the case, you might want to disable the error message. To disable the error message, follow these steps.

  1. Click Start, and then click Run.
  2. In the Open box, type ncpa.cpl, and then press ENTER. The Network Connections dialog box opens.
  3. Double-click Local Area Connection, and then click Properties.
  4. On the General tab, click to clear the Notify me when this connection has limited or no connectivity check box.
  5. Click OK, and then click Close.

Check for other causes and solutions loadTOCNode(2, 'workaround'); If you cannot connect to the Internet, you have to find the reason. Realize that the reason may not be with your computer, but may be an issue with your Internet service provider (ISP) or with issues on the network at your work. Therefore, for some of these solutions, you might need help from your ISP, or, if your computer is part of a network at work, you may have to ask your network administrator for help. Contact your ISP service loadTOCNode(3, 'workaround'); If you use an ISP to connect to the Internet, before you go any further, first contact your ISP to see whether it is experiencing any problems. If the ISP has problems, wait until the problems are resolved before you continue to troubleshoot. Check the hardware devices loadTOCNode(3, 'workaround'); If you still cannot connect to the Internet after you have confirmation that your ISP is not experiencing any problems, manually check the hardware devices on your small office network or your home network for problems. For example, if a hub, router, modem, or access point is installed on your network, check that it is connected correctly, and that it is turned on and functioning properly. The solution might be as simple as turning on or restarting a hardware device, and then restarting your computer. For more specific troubleshooting information about the hardware devices that you are using, refer to the hardware documentation for your devices. Run the Network Diagnotics tool loadTOCNode(3, 'workaround'); If checking and restarting your hardware device did not resolve the issue, your computer may have a networking problem. For example, your computer may not have an IP address or your TCP/IP settings may be corrupted.

There are tools available in Windows XP that you can use to help you diagnose and troubleshoot networking problems. To use the Network Diagnostics tool to determine the source of the issue, follow these steps:
  1. Click Start, and then click Help and Support.
  2. Under Pick a task, click the link to Use Tools to view your computer information and diagnose problems, and then click Network Diagnostics in the list on the left.
  3. Click Scan your system. The Network Diagnostics tool collects configuration information and performs automated troubleshooting of the network connection.
  4. When the process is complete, look for any items that are marked "FAILED" in red.

    Note If you do not see any categories that failed, please see the "Additional troubleshooting information" section for more information about how to troubleshoot network problems.
  5. Expand a category to view the testing results. For example, to check the results for TCP/IP settings, expand the Network Adapters section. Then, check whether a network adapter has failed.
  6. You can use that information to try to resolve the issue yourself, or you can provide the information to your network administrator for help. If you are not sure how to use the results from the Network Diagnostics tool to resolve the issue, see the "Next steps" section for help.

Dryer not heating - I replaced the heating element and it still isn't drying.

Yes there is a thermal fuse and a hi limit switch. The hi limit switch is attached to the heating element casing. You said the heating element checks out If you checked it with an ohm meter and it checked out good. If you checked it visually double check it. The hi limit can be checked with an ohm meter it should show continuity. If you dont have a ohm meter you can jump the wires by connecting them using a paper clip or copper wire. Make sure to tape them with electric tape. The thermal fuse is connected with the Heating element and hi limit by one wire and is located at the bottom back of the dryer and slightly to the right as you face the back of the dryer. It is a small two wire fuse and once it trips you have to replace it you can check it and test it just like the hi limit switch. Be careful and always unplug the dryer before starting any repairs. I hope this help. If you need me to clarify anything just let me know. good luck

Problem with Network and Wireless driver


Hello Ken,

It sounds as if the problem is with your wireless setup. If you go into your property setting for the wireless when you are "connected" to your router, make sure it is showing a Gateway IP address. If not, you get limited or local access only. You will need to get the gateway IP address from your ISP provider or if you know the IP address of the router (DHCP) you can get all the IP addresses to get you connected to the Internet.

Good Luck

When your network shows limited connection, it could be that you system did not pick IP address from your DHCP server. so it assigned itself a public IP address. In this case make sure your system has the correct networking setting and it can reach the DHCP Server. If you are using a modem, the service from your service provider may be poor in your area.

Power Surge on Hub Port


Some USB devices draw excessive power from the USB port, especially USB scanners. When this happens you need a powered USB hub, connect this to your computer's USB port and connect the USB device into the powered USB hub, you should not have any further error power surge problems.

Limited or no connectivity


you need to get into the routers settings (192.168.1.1 in your web browser) and look for DHCP, and enable it so as to give your pc's there automatic ip addresses, also check in the general settings if it's a modem router that you have got a internet connection from your ISP and all the dns and ip addresses are showing. Go to the properties of each network card in network connections in your control panel and click on the TCP/IP line and click properties again and ensure obtain ip address automatically is selected and click ok. Restart all pc's if neccasary and refresh your web browser when trying to get online.
