Forgotten password for wifi network


Which operating system ??
Your wireless Internet password is the encrypted security pass phrase that was set up when you installed your wireless router.

Your router allows you to access the Internet.
If you have access to more than one wireless network, you may need to remember multiple passwords.

If you happen to forget one password, you have two options: reset your password or locate the current password.

Windows 7 allows you to view the security characters of all your wireless network passwords.
Click the "Wi-Fi" network icon located on the Window's taskbar.


Right-click the name of your network's "SSID" name and select "Properties" from the drop-down menu.


Click the "Security Tab." The network security key is now visible but unreadable.


Click the "Show Characters" check box and this will reveal your wireless password.

Reset My WiFi Password

Wireless networking is a common feature in homes and offices.
Wireless routers provide access to a single Internet source, and wireless passwords ensure that only select users can access the network.

If a password is forgotten or lost, the password can be recovered or reset by accessing the router's Web-based settings menu.

Most wireless routers also have a reset button, which is capable of returning the router to its default settings which includes resetting the password.

Connect to your Wi-Fi or attach your computer directly to the router with an Ethernet cable.
Open your Web browser.

Enter the default address of your router.
The default address is listed in your user manual or on the product website.

Linksys and 3Com routers typically use "192.168.1.1" while Netgear routers use "192.168.0.1."
Enter your username and password.

Many routers use "admin" for the username and password by default.
Locate the wireless security settings. Disable the wireless security.

Reset to Factory Defaults

Locate the reset button on your router.
Typically the reset button is a small indented hole on the back of the device.

Insert a long thin object such as a paperclip and hold down the reset button for 30 seconds to revert the router to its factory default settings.

Open your Web browser.
Enter the default address of your router.

The default address is listed in your user manual or on the product website.
Linksys and 3Com routers typically use "192.168.1.1" while Netgear routers use "192.168.0.1."

Enter your username and password.
Many routers use "admin" for the username and password by default.

Locate the wireless security settings and add security as necessary.

I forgot ip address and password and want to factory reset


Connect the console cable, open a connection to the serial port via a utility such as PuTTY, and do the following:
1) Enter the user name "recover" and password "recover" to place your unit in password recovery mode. The unit will remain in password recovery mode for 30 seconds max.
2) Perform a hard reset by removing power, waiting 10 seconds, and then re-applying power.
3) Once the switch has rebooted, enter a new password for the "admin" user account.
4) Enter enable to leave password recovery enabled, or enter disable to turn it off. You are now logged in as the default "admin" user.
Note: If password recovery has been disabled, the only way to recover access is to return the switch to 3com.

Forgot ip address and password


To re-enable the Console access requires the SW2900 series to be reset to its default settings via the WEB INTERFACE
- Web Interface
- Device >Configuration >Initialize To change the Default User "ADMIN" password it is necessary to use the Console connection
-Console Interface
-Once the unit has successfully booted and the prompt presented
-Enter "password" (without "")
-Enter "admin" when the system prompts for User
-Press the "Enter" key when the system prompts for "Old Password" (the ADMIN password was reset by the Web Interface commands)
-Enter "" when the system prompts for the New Password (where "" is the new product ADMIN password)
-Enter "" when the system prompts to confirm the New Password In order to complete the configuration it is necessary to save the configuration via the WEB INTERFACE
-Web Interface
-Device > Configuration > Save
Symptom:
SW2900 Baseline Switch - Default console access disabled following password change
From the web interface, the default user "admin" password is changed and console access is disabled
Cause:
When applying the new password, by default the service-type is set to "telnet". When applied, the default "terminal" setting is removed thus disabling console access.

Hello sir..im have the switch model 4924 24 port....i want to reset but dont know how to do that....can u help me to settle this prob sir...i want to make this switch like new means the function like new...


Connect some text-based terminal emulator such as Hyperterm, telnet,VT100, etc to the serial port. Configure the emilator
to19200 Baud 8 plus none.

Switch the 4924 on and login using the user "recover" (without quotes) and password "recover" (also without quotes.

The switch will go into recovery mode. It will display a count-down starting at 30 seconds. If you power thye switch off before the count is up, the default password for the main administration account "admin" will be cleared.

After a few seconds, power the switch on and set a new admin password.

After loigging in again, take the option "GettingStarted". Configure the ip settings (best to use a static address) and eventually you will get to the "Initialize" option. Enter yes, and after reboot it will be at factory except for its ip address.

Wants to reset 3824 3com switch via console


You forget the password for the "admin" user account and can no longer perform important management operations. solution.gif Use the password recovery method outlined below to define a new password for the "admin" user account:
  1. Access the Command Line Interface from the console port and enter the user name "recover" and password "recover" to place the Switch in password recovery mode. The Switch remains in password recovery mode for a maximum of 30 seconds, before it returns to the CLI login prompt.

    note.gif You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.

  2. Perform a hard reset on the Switch whilst it is in password recovery mode by switching it off, waiting a few seconds, and switching it on again.

    note.gif You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.

  3. When the Switch has rebooted following the hard reset enter a new password for the "admin" user account.
