Question about NetGear Super G Wireless Router
Hi, I have comcast high speed internet and i can't connect using the netgear wireless router. The problem is that when I plug the internet cable to the wireless router and connect the router cable to the computer, there is no internet. My modem says its connected but I cant access any websites. I did what the instructions did but it's still not fixed. How do I fix this?
Here's sort of a checklist of things to consider:
1. First of all, connect the computer directly to the cable modem. Make certain that your ISP (Comcast) is providing internet service. Modems (DSL, cable) typically have a web page (HTML document output format) interface through which you can connect with your favorite HTTP client (that is, browser), such as MS Internet Explorer or Mozilla Firefox. You can always connect to that if your computer has been given an IP address: you would look for the device you are connected to (modem, router) as the "gateway IP address" (for modems, it might be a 10.0.0.x IP number or something like that; for routers, it might be a private LAN address of 192.168.x.x or 172.16.x.x or something like that). Type in the gateway IP address: if it unsecured, you will see the interface immediately with gettable (status) and settable (configurable) form controls; if it requires authentication, you must enter a username/password combination to gain access to the interface. The default username/passwords are provided in the user guides of the device from the manufacturer.
2. Once you are sure the modem is providing service and that you have configured it properly, then remove the connection to the computer and connect the router. Check that all the lights of the router illuminate properly after startup.
3. Now connect BY ETHERNET (Cat 5 unshieled twisted pair) cable your computer to the one of the slots to the router. We'll go wireless later. Make sure that you are now getting internet service through the router while connected to it with the Ethernet cable. Make sure that you are talking to the router through its web interface. Again, look at your internet settings (find the gateway IP address), and enter that IP address into your browser. You will be challenged for authentication: use the router's default authentication (usually the user name is "admin" and the password is also "admin" or maybe a number sequence like "123456", I don't have your super G model number) and then enter the Interface. Perhaps you need to make special settings for the type of broadband: VCI and VCP values and protocol for the WAN side. You might need to learn these from Comcast's support (by phone or by web site).
Alternatively, rather than us the browser interface to your router, Netgear may provide a CD install disk which contains an application you run to directly manage your router device. It will configure it and also set it up for wireless (see next step).
When you see web pages (such as Google, Yahoo, even Comcast's) through your router, then you are ready to configure the wireless part.
4. While still connected to the router's web page interface in admin user mode, look for the wireless part. You need to set an SSID (don't use the default...create a name you can recognize). This SSID is broadcast to the wireless and you will identify it when opening your computer's wireless adapter. Set an authentication mode as well, so that only you and other can connect to your wireless and no one else (prevents unsecured connections, and turning your wireless into an open "hotspot"). Use WPA or WPA2 (not WEP) if you have it, and you will be given or asked to create a key which is probably a series of numbers and the letters A through F (a long hexadecimal number). Write down the authenticatin type (WPA or WPA2 with AES or TKIP and the key value) and then write this information in for the wireless setup of all computers wishing to connect to the router. You can create this also if Netgear provides an interface (by an CD install disk) for your computer: it may tell you to insert a USB drive to copy information that you would then use to configure all computers that will use the wireless, since it will setup a network configuration that includes the authentication key.
For specific information about how to configure the wireless adapter for router connection, you would need to give the OS you are using (WinXP? Win Vista? MacOS? Linux?)
In future posts, or messages to me, please as a rule provide as much information as possible about ALL devices, namely make AND model/product numbers, since often the experts can check online to see how you can interface with these and configure them.
