here's the page, check the firmware in your router and see if it's older than these

The reason why your internet light is red for the actiontec gt701-wg is because it is not yet configure. You need to access the gui of this router. enter the username and password for your internet connection. You can contact your ISP provider so they can walk you through for the steps on how to configure your new router.

The old router has green light because it was already configured by your ISP provider.

Yes this is a normal method to setup a wireless network.
To set-up and secure the wireless router from unauthorized access, follow these steps :-
1. Connect the wireless router to your computer with a LAN cable.
2. Start your browser and enter the router's configuration URL IP address.
3. Enter the router setup, login and password
4. Change the admin password
5. Go to the wireless settings and change the default SSID and turn off SSID broadcast.
6. Setup encryption key the strongest is WPA2 (if not then WPA).
7. For further security measures - turn on MAC address filtering and enter the MAC address of the wireless cards on the computer/s you want to connect to this wireless router.
8. Record the settings you have made and keep it in a safe place and Save the settings.
9. Configure the wireless cards on the computer/s with the SSID and encryption settings of the router.
10. Remove the LAN cable between the router and the computer then the computers should be able to connect to the router.

Flip over your ACTIONTEC and you would see there the default wep key. If you've had it personalized before, you have to open the configuration page of your modem and check for the wep key.

To go to the configuration page, open your internet explorer and type in 192.168.1.1 on the address bar. that is the default address for your actiontec. type in your username and password when prompted. the usual default it ADMIN for username and PASSWORD (lowercase) for password. or you could also try ADMIN (uname)-ADMIN(pword).

click on the wireless settings icon and then click on basic security settings. scroll down on the middle of the page and you will see there your wep key.

if you are unable to open the configuration page because you forgot your username and password, you can reset your modem so that it the uname and password will go back to its factory default settings (admin/password). However, if you are using pppoe connection (authentication using username and password to connect to network) you can lose your connection and you would have to configure your router. so be careful not to press the reset button at the back.

If you're using 64-bit WEP Key, it would usually require you to put in 10 digits from 0-9 and A-F. so if you're putting in your wep key, make sure it's using only the characters 0,1,2,3,4,5,6,7,8,9, A,B,C,D,E,F.

Yes, if the other isp is also providing dsl services, but you will have to configure the device the other isp will not help you with that.

but its really not that difficult.

In looking on the internet the unit is a DSL gateway. Trying to use it on cable internet is not a real good way to set up your network because I believe the router is waiting for a DSL sync before the services turn on. I would spend the money and pick up a Linksys or Netgear G router, there around $50.

You can use USB instead of Ethernet port but its not a common practise. Leave it empty then.
