Forgotten Router Password

Try the default username and password before resetting the router to the factory defaults.

  • The router username is always admin
  • The default password is password or (for older routers) 1234

Default Logins and Passwords for Networked Devices


When a router resets, it goes back to the state when it was new — all information that was entered by hand is lost.

Reset for most routers with a reset button on the rear panel

Write down configuration information such as IP addresses, security keys, opened ports and services, etc., that you modified. (The default username is admin and the password is either password or 1234. Try these before resetting the router.)

  1. Press the reset button on the back until the test light blinks. This takes about 10 seconds. (To avoid accidental resets, the small button is recessed. Use a pen or paperclip to access it.)
  2. Release the button.
  3. Wait for the router to reboot.
  4. Log in with the default password.

    If the router was not cleared, try these additional steps AFTER the router has finished rebooting.

  5. Unplug the router's power.
  6. Press and hold the reset button. While the button is held down, reconnect router's power.
  7. Continue to hold the reset button for 20 seconds after reconnecting the power.
  8. Wait for the router to reboot.
  9. Log in with the default password.

Speed Up your PC

Free up disk space

By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.

Use Disk Cleanup to:

•

Remove temporary Internet files.

•

Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).

•

Empty the Recycle Bin.

•

Remove Windows temporary files.

•

Remove optional Windows components that you don't use.

•

Remove installed programs that you no longer use.

Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.

To use Disk Cleanup

1.

Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.

2.

In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.

Choose the files that you want to delete.

3.

Clear the check boxes for files that you don't want to delete, and then click OK.

4.

When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.


Speed up access to data

Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.

Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.

When to run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:

•

You add a large number of files.

•

Your free disk space totals 15 percent or less.

•

You install new programs or a new version of Windows.

To use Disk Defragmenter:

1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.

2.

In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.

Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.

3.

To defragment the selected drive or drives, click the Defragment button. Note: In Windows Vista, there is no graphical user interface to demonstrate the progress—but your hard drive is still being defragmented.

After the defragmentation is complete, Disk Defragmenter displays the results.

4.

To display detailed information about the defragmented disk or partition, click View Report.

5.

To close the View Report dialog box, click Close.

6.

To close the Disk Defragmenter utility, click the Close button on the title bar of the window.


In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.

If you use your computer daily, you should run this utility once a week to help prevent data loss.

To run the Error Checking utility:

1.

Close all open files.

2.

Click Start, and then click My Computer.

3.

In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.

4.

In the Properties dialog box, click the Tools tab.

5.

Click the Check Now button.

6.

In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.

7.

If bad sectors are found, choose to fix them.

Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.
