Occasionally, problems may occur with your wireless router. When they do you are likely to lose all or partial access to the internet, and so you will want to resolve them as quickly as possible.

The first thing to do is work out whether you have completely lost access, or whether it is just running very slowly. If it is down completely then it is likely that your internet service provider is having problems and you may not be able to overcome it.

When your net goes down completely your modem will normally display a warning signal in the form of a flashing light, or the absence of the light that normally indicates that the internet is working.

Your router may also display a similar warning-the modem input light may change to red, may flash or may stop showing.

When this happens you can try and reboot both the router and the modem. However if this does not work you are likely to have to wait till your service provider corrects the problem.

Other times you may notice that your internet speeds slow to a crawl. When this happens you should check the time-at peak times (such as around 7pm on weekdays) there are so many people online that the traffic slows down everyone’s speeds. Again there is nothing you can do but avoid these times and wait till the speeds increase again.

Other causes of slow downs may be directly attributable to your router. Signal loss may occur for three reasons:

1. Where there are concrete walls or metal objects between the router and the wireless device.
2. Where the device is so far from the router that it cannot pick up the signal.
3. Where there is interference from another wireless device nearby.

You can work out what the cause is through a process elimination. First, check the building you are in to see if there are any obvious concrete or metal obstructions to the signals.

Next, check the distance from the router, and compare it to the distance that your router is rated for. Most routers have a movable antennae, that can is directional. Point it in the direction of your device and see if you get a better result.

Lastly you should check the area for other wireless devices. If there are others, try turning them off and trying your router again. If the router runs better, then you can be fairly certain that there is interference.

Most routers will come with the option to run on different channels, that use different frequencies and these can be found in the administration panel. Try selecting a different channel, turning your other devices back on and see if it runs better.

If you cannot overcome your signal loss, you may consider buying a signal booster. These are placed in a position where they can adequately receive the router signal before relaying it onto devices that otherwise would not receive the signal.

Sometimes the router genuinely won’t work because of a fault. You can try plugging a wire in from the wire and connecting that way to establish that it is the wireless that is faulty, and not the internet connection.

If, sat within a meter of the router you do not pick up a signal on a device that otherwise is known to receive wireless, then you are right to suspect a router fault and will need to either replace the router or have it repaired if it is under warranty, but hopefully the problem can be found and resolved without it coming to this.

You may encounter many different types of strange error messages while working on your Windows computer. These errors may not only prevent you from working on your PC, but may also cause unnecessary frustrations.

Listed below are a few easy tips to help you troubleshoot strange error messages and resolve them.

When an error message is displayed, ensure that:

• Your system meets the requirement to perform a particular task

Many computer errors occur if your system does not have the required software, hardware, or driver to open a particular file.

For example, if you try to play an XviD movie on your computer and you do not have XviD codec installed on the PC, the missing xvidcore.dll error may be generated. In this case, to resolve the error, you will have to obtain and install the XviD codec and then attempt to play your media file again.

• Program and DLL files required to run a software are not corrupt, damaged, or missing

Rundll and other program errors, like the one given below, may occur if a required DLL or program file are missing from the system or are corrupt:

rundll32.exe – Unable To Locate Component

This application has failed to start because framedyn.dll was not found. Re-installing the application may fix this problem.

The first thing you can do to resolve such error messages is to try to replace the file that is reported as corrupt or missing. If the file belongs to a software application, the best thing to do will be to reinstall the application or update it.

It is recommended that you first uninstall the faulty application, using the Add or Remove Programs utility or a reliable third-party program uninstaller and then perform the reinstallation.

If a system file is corrupt, you may perform the following tasks to replace the missing file:

Use Recovery Console to extract and copy the faulty file from the Windows XP installation CD.

Perform System Restore to revert your system to the time when there was no error.

Reinstall the operating system—use this method as the last resort.

• Your system is free of Malware infections

If error messages start appearing all of a sudden, it may be an indication of some kind of malware infection. Malware programs, such as virus, Trojans, and spyware may infiltrate your PC through infected email attachments, freeware and shareware software, open network shares, and infected external media that you may connect to your PC.

To prevent these malicious infections, you need to install and configure essential security tools, such as firewall, antivirus and antispyware on your Windows PC. You must regularly perform full system scans using the antivirus and antispyware tools to detect and remove any malicious information.

• Windows registry is free of unwanted data and errors

As you work on your PC, a lot of data is added and removed from the registry. Quite often, information that is no longer required stays behind in the registry causing the registry to bloat up to a very large size.

A large, bloated registry becomes unstable and starts generating various computer errors. To prevent and fix registry problems, you need to scan the registry and rectify the detected errors. To do this task, you may use a reliable and easy-to-use third-party registry repair utility.
