1. How to change MAC address of an Network Interface Card (NIC) ?

First, select the Network Connection for which you want to change the MAC address and click on Change MAC button. Now enter a new MAC address in hexadecimal format in the six blank text boxes provided for each hexadecimal number. You may click the Random MAC Address button to generate a random MAC address from the available list of manufacturers. You may also select a particular Vendor/Manufacturer from the drop down list to get a random MAC address for the selected vendor.

After entering a MAC address select the Automatically Restart Network Connection To Apply Changes check box if you want to restart the network connection. Not selecting Make New MAC Address Persistent check box would change the NIC MAC address to original when the computer restarts or the NIC is disabled. Click the Change Now! button and confirm changes you made when prompted.

2. How to change MAC address back to the original MAC address of NIC ?

To change MAC address back to the original MAC address of the NIC, just click the Change MAC button and then click the Original MAC button and confirm the changes you made when prompted.

3. How to Enable/Disable an Network Connection ?

Select the Network Connection for which you want to perform the required operation and click the Enable/Disable button to enable/disable the network connection. After you click TMAC will not respond for 5 seconds. A message window will appear after the operation is completed.

4. How do I refresh the Network Connection list ?

To refresh the Network Connection list, Click Options menu and click the Refresh menu item. You can also do this task by pressing F5 key.

5. How can I add/remove an IP address ?

To add an IP address, click on the << Add >> button, a menu will appear. Click on the IP Address menu item, an editor window will appear inside the main window (see screen shots). Enter IP address and enter the subnet mask. You can enter the subnet mask directly or enter a CIDR style notation for example /24 for 255.255.255.0 subnet mask. Select the checkbox below if you want to make the IP address persistent. An persistent IP address will be saved in registry and will persist across system reboots. An non persistent IP address will be flushed when the Network Connection is disabled or system rebooted. Now click Add IP button to instantaneously add IP address to the NIC.

If you click on the IP address list and start typing a new IP address, the IP address editor window will appear automatically saving time.

To remove an IP address, select the IP address from the list and press Delete key on your keyboard or you can click the << Remove >> button, a menu will appear, select the IP Address menu item to remove the selected IP.

6. How do I add/remove an Gateway ?

To add an Gateway, click on the << Add >> button, a menu will appear. Click on the Gateway menu item, an editor window will appear inside the main window. Enter IP address of the Gateway and enter the metric or check the Auto Metric checkbox. If metric is not specified, it assumed to be automatic metric. Select the Persistent Gateway checkbox below if you want to make the Gateway persistent An persistent Gateway IP address will be saved in registry and will persist across system reboots. An non persistent Gateway IP address will be flushed when the Network Connection is disabled or system rebooted. Now click Add Gateway button to instantaneously add Gateway IP address to the NIC.

If you click on the Gateway list and start typing a new Gateway IP address, the Gateway IP address editor window will appear automatically saving time.

To remove an Gateway, select the Gateway IP address from the list and press Delete key on your keyboard or you can click the << Remove >> button a menu will appear, select the Gateway menu item to remove the selected Gateway.

7. How do I add/remove an DNS Server IP Address ?

To add an DNS Server, click on the << Add >> button, a menu will appear. Click on the DNS Server menu item, an editor window will appear inside the main window. Enter IP address of the DNS Server and click Add DNS button to instantaneously add DNS Server IP address to the NIC.

If you click on the DNS Server list and start typing a new DNS Server IP address, the DNS Server IP address editor window will appear automatically saving time.

To remove a DNS Server IP, select the DNS Server IP address from the list and press Delete key on your keyboard or you can click the << Remove >> button a menu will appear, select the DNS Server menu item to remove the selected DNS Server.

8. How can I change DNS Servers priority ?

To change the DNS Server priority, select the DNS Server IP Address from the list and click the Up and Down arrow buttons, situated on the right side of the list, to move the priority either up or down. The top most DNS Server IP address has highest priority while the bottom most has the least.

You can even hold the ALT key on your keyboard in combination with the UP and DOWN navigation keys to perform the above operations.

9. How to enable/disable DHCP on an Network Connection ?

Select the Network Connection on which you want to enable/disable DHCP and click the Enable DHCP/Disable DHCP button to perform the operation. You will be prompted to restart the selected connection in order to apply changes.

Note, all the previous IP and Gateway settings will be deleted when DHCP is enabled/disabled. Hence you are recommended to create Configuration Preset for the connection before performing the operation as in case you wish to revert changes.

10. How to Release IP and Renew IP lease for selected connection ?

Select the Network Connection on which you want to Release IP/Renew IP lease and click the Release IP/Renew IP button to perform the operation.

Note, TMAC will not respond till the operation selected is finished or it has timed out.

11. How do I set Interface Metric ?

Select the Network Connection on which you need to change the Interface Metric, click on the Options menu and click the Interface Metric menu item. You will be prompted to enter a metric value in a new window. The existing value in the prompt is the current value. Zero value indicated automatic metric. Enter a value and click OK to set a new Interface Metric value.

12. How to create/modify/delete an Configuration Preset ?

Select the Network Connection whose settings/configuration is to be saved as a Configuration Preset and click the Create button, an Configuration Preset window will appear inside the main window. Enter a name for the preset. Make sure the name is such that you remember the configurations saved inside it. Name can contain any characters and can be of maximum 255 character in length.

Select the parameters like MAC Address, HTTP Proxy, Enable DHCP, IP Address, Gateway and DNS Server using the check box provided. Only the selected parameter values of the selected network connection will be saved inside the Configuration Preset. When a preset is applied to any network connection, only the selected parameters for the network connection are changed while the other/remaining parameters are not affected (You may like to try it yourselves to get the idea better).

If for the MAC Address parameter, you selected Use Current MAC Address then the preset will store the current MAC address of the selected network connection and use the stored MAC address to set on any interface its applied to.

If you select the Use Original MAC Address then the preset will use the original MAC address on the network connection its applied to. Any changed MAC address on the applied network connection will be removed in this case.

If the Use Random MAC Address is selected then a random MAC address is selected from the available list of vendors every time the preset is applied to any network connection. Any previous MAC address on the applied network connection will be changed to a random MAC address.

If you enter the preset name which already exists, you can over write it such that the new settings will be saved onto it, thus modifying the preset.

To delete a preset, just select the preset from the drop down box and click the Delete button and confirm the action.

13. How to apply an Configuration Preset ?

To apply a preset to any network connection, select the network connection and select a required preset from the drop down list and click on the Apply button. You will be prompted for confirmation, click yes to proceed. After applying the preset you will be prompted to restart the network connection to apply the changes, click yes to apply the changes.
