I am connected via ethernet cable to my cable modem (Motorola SB5100). I am connected but my browser doesn't display any websites. Except, what I found on Internet to try, is IP address. SO when I type yahoo IP then it goes up but URL don't. I tried already many things that I found on Internet but nothing helped. Do you think reinstalling WIndows again can help or is there anything easier to do???
And additional question-if I connect WI-Fi adapter to this cable modem can I use Internet wirelessly? Or cable modem is only cable modem???
you didn't mention which version of windows are using so i am going to assume that you have windows XP if that is not the case then let me and i can provide you with an alternate solution.
1. click on the start button 2. click on run 3. type ncpa.cpl 4. right-click on local area connection(if using ethernet cable) 5. single-left-click on internet protocol (tcp/ip) 6. click on properties 7. click on set dns servers manually instead of obtaining automatically 8. enter 184.108.40.206 and 220.127.116.11 as the primary and secondary servers. 9. restart the computer
if it still doesn't work 1. click on the start button 2. click on run 3. type cmd 4. click ok 5. type nslookup www.google.com 6. hit enter

The wireless key is listed on some modems/routers. It mightbe listed on somewhere on the device. AT&T places theirs on thedevice for you.
If not, you can always plug an ethernet cable from the router into the ethernetport of a computer and type in the router's ip address in the browser. For example the ip address will be something like 192.168.1.1
Once you have the correct ip address ( you can google your router'smanufacturer for the ip address if you don't know it), then the routers guiinterface will open up for you to configure the router. It will ask forthe user id and password. Most times this is the default password set bythe manufacturer unless whoever installed your router changed it. You canalso google your router's manufacturer for the default user id andpassword. In fact you could go to the router's manufacturer's website andlook at the manual for your router which will have the ip address, userid andpassword.
Once you are in the router you can go to the Wireless Settings and WirelessSecurity to see the key.
Seems like your Operating System is Vista or Win7.
Well make sure you are connected with Ethernet cable
Go to Start - type CMD and click CMD on top
You will be MS-DOS prompt
Type - IPCONFIG and press enter
Check IP address and Default Gateway for Local area connection
Open Browser, type the IP address you saw in Default gateway and press enter
You will be asked to type the username /password for your Router
check Wireless settings there and change your SSID and password
Now try connecting to the wireless network after removing ethernet cable
You may sometimes need to connect to a wireless router locally to update its configuration. Accessing a wireless router's configuration screens requires you to know the router's IP address as well as the admin log in name and password. You should also be aware of a few common Wi-Fi connection problems and how to solve them.
Verify the current local IP address of your router.
Home broadband routers are manufactured to use a default address such
as 192.168.0.1, 192.168.1.1, or 192.168.2.1.
Verify your computer is connected to the router either via an Ethernet cable or wireless association with the router. In either case, ensure your computer possesses a valid IP address.
Open a Web browser window and request a connection to the router using its local IP address. For example, type http://192.168.1.1/ in the browser's address bar to request a connection to a router using the IP address 192.168.1.1.
the browser request is successful, you will be connected to the router
and prompted for the administrative log in (user-name and password)
information. Enter the administrative log in information to
authenticate yourself to use the router's admin screens. Broadband
routers contain default user names and passwords when first installed.
Consult your router's documentation if you need to know the default
If the browser request returns an error message, your computer is likely not connected to the router. You may need to perform additional troubleshooting to establish a connection. Try the following procedures and repeat step 3 above as needed to resolve any connection problems:
a. Reboot (power off and on) your router
b. Temporarily disable your network firewall
c. Reset your router to factory defaults (consult the manufacturer's documentation)
If this is the first
time you are connecting to a wireless router for admin work, consider
using a wired Ethernet link rather than a Wi-Fi link. Your Ethernet
connection will keep working even if you haven't finished configuring or
accidentally break the Wi-Fi settings.
Sometimes when dealing with IP addresses, DNS, etc... you system does not update automatically. in your case, i think you are having a problem of renewing IP address and gateway... open Run CMD.
type ipconfig /release.
this command shall release all automatic IP. then you do ipconfig /renew. this shall renew the ip address.
You possibly have your router password protected or have changed the password recently. If you have done either, you will need access the router by the router IP address, then go in and make sure the password you have on the router is the same as the password you have no the computer.
Secondly, make sure that the router is broadcasting correctly. Hard wire(hook the computer directly to the router with a ethernet cable) to see if there is an internet connection flowing thru the router.
Third, ensure that the ethernet cord from your modem to your router is a good cord. Be sure to plug the ethernet cord from your modem directly into your computer to ensure there is a good connection as well.
Reconnect all (modem, router, and computer)
Fourth, power down router, modem, and computer together. Power up the modem first and let all the lights come on. This will renew the connection and refresh the IP address. Once the modem is up, then power up the router til all the lights are powered on the router. Lastly, power up the computer to the desktop and attempt to launch a web browser (internet explorer, mozilla, safari, etc.).
If nothing at this point works, you will have to consult your router manufacturer or a local computer repair shop. Be sure that the technicians working on your issue is certified.
Plug in the laptop to the router and the router to the modem. Power cycle the modem. Turn on power to the router. Copen a command prompt on the laptop and type 'ipconfig /all' and press Enter. Look for your IP address (should have been assigned by the router and should look like 192.168.1.x). Also look for the default gateway. It will probably be 192.168.1.1. If that is the case, you should be able to use your web browser to connect to the router to check its configuration and the WAN status by typing in the address 'http://192.168.1.1' (or whatever was displayed for the default gateway previously.
First: In your system tray (lower right corner of windows) right click in your wireless network icon and select "repair". After it finishes, try your connection again. (If you can't find the icon in the system tray, go to control panel, network connections. Right click on the wireless network, and select "repair".)
Second: Try to connect to your router directly by typing it's IP address into the address bar of your browser (Internet Explorer or Firefox). *****If you don't know the IP address, you can find it by opening a command prompt window (click "start", "run", then type "cmd" and press "ok") In the command box, type "ipconfig /all" (all of these commands I have told you are without the quotes.) In the information that is returned, look for the Default Gateway. Usually it is something like 192.168.1.1 but yours may be different. This is the IP address of your router.***** If you cannot connect to the router through your browser, then the router is the problem...Unplug it from the power for about thirty seconds, then plug it back in. Wait for a couple of minutes while it gets up and running again, then try your internet again. (Whenever I have repaired this problem in the past, I have also unplugged the cable modem which forces the modem to query for a new IP address for itself. If you do this, plug the cable modem (or DSL modem) in first, then plug in the power to the router. If you CAN connect to the router with your browser, you should see the administrative options. Search through the tabs and options to find an option to release and renew it's IP address. I hope that I didn't overwhelm you with too much information here, any questions, just post them here and I will help you.
