In order to adjust wireless settings you need to access the configuration settings of your router.
You need to type in the address of the router into the address bar of your browser in order to access the configuration settings.
According to Netcomm the default address is 192.168.1.1 (so type this in your internet browser)
The default username is: admin
The default password is: admin
If the username or password do not work and you do not know them, then you will need to reset the router by using a paperclip to hold down the reset button for 10
seconds. When the lights turn steady green, the reset is complete and you can login with the information I provided above. Warning: This will change all configuration settings back to the default "out of the box" state.
