Netopia modem can't connect to internet

First check the ip address:

1.Go to the dos prompt and type in ipconfig
2. An invalid ip address is anything that start off with 169.xx.xx.xx
3. If it give you an a valid ip address, go to a blank line on the dos prompt
4. Type ipconfig/release..press enter. A lot of information is going to come up
5. Go the next blank line in dos type ipconfig/renew.
6. Then power cycle the modem and computer by turn the modem completely off and then turn off the computer for 3 minutes. Then turn the modem and computer back on. Check to see if this work.

refresh or reinstall and stall back again your yahoo. must be some virus causing this

I have a couple of questions

1. What gateway are you pinging?
2. From what device are you sending the ping?

If you are trying to ping the gateway on the modem/router provided by your internet service provider then you will not get a ping response, this is because it's configured not to respond.

Here's a driver-free, software-free solution.

Turn your cable-modem (or DSL-modem) off.
Turn your Netopia off.

Connect:

Ethernet--port on cable-modem <-- cable --> WAN port on Netopia.

One LAN port on Netopia <-- cable --> network-port on your computer.

Turn the cable-modem on, and wait until its lamps settle-down to a repeating pattern.

Turn the Netopia open, and wait until its lamps settle-down to a repeating pattern.

Restart your computer.

Click Start
Click Run
Type CMD
Press Enter
Type IPCONFIG
Press Enter
Look for output like: Default Gateway ... 192.168.123.456
Start Internet Explorer
Type http://192.168.123.456 (or whatever numbers you see)
Login to the web-server running "inside" the Netopia.
Click to run the "Wireless Networking Setup Wizard".
Enter an SSID of your choice.
Select the 'WPA' level of encryption.
Enter a network-password of your choice.
Click OK
Restart the router (if it did not automatically restart).

Disconnect the Ethernet cable from your computer's network-port.
Click "View Available Wireless Networks".
Click the SSID of your new network.
Click Connect.
Enter the password, when prompted.
Voila! You have a wireless connection to the internet.

Connect directly to your ISP by what ever method. Get Network Magic from Cisco. Download the free evaluation copy and run it. Reintroduce your router and let Network Magic help you solve the trouble. It may be that your firewall is too tight.

I hope this helps you

first of all change your wireless settings again.if it`s vista choose WPA,if it`s xp choose WEP.Try the channels from 3,6,9,11(and 13 if it`s available depends on your country).disable MAC security if it`s on. try connecting now.try to use internet.if not then goto start - run - .cmd - enter..type ipconfig.ping the default gateway,if successful then ping 4.2.2.2 ,if successful then ping www.yahoo.com.all ping statistics should say sent = 4,received = 4,lost = 0.if not u need to disable all securities like firewall and antivirus.update adapter`s driver & router`s firmware.provide fixed IP under wireless network connection and DNS server address should be 4.2.2.2 & 4.2.2.3. restart your computer it should work.if it doesn`t then change ur wireless settings again and connect without security.
come back for more advance steps if it doesn`t work.also provide model of router. Thanks..

Try to open the required ports of your web server on your router.

Sounds like either a cable has come unplugged/broken, the router/modem is on its way out, or your DNS cache needs to be cleared.
In this order:
Unplug the modem and/or router power cords. While unplugged, make sure the cat5 cables are connected securely(if using wired net).
Wait about 30 seconds to a minute, then plug the modem and/or router back in.

Test your internet connection.

If there still no connection to the internet, Click Ctar>Run, type in cmd, hit enter. This opens the command prompt.
On the black screen, type in ipconfig/flushdns
Close the command prompt, and re-test your internet connection.

If it still fails, verify with your ISP that your internet connection is active, and try a different router and/or modem.

Can you ping them, there may be a type of firewall that is blocking that traffic on the netopia router. Try and ping between computers and see what you have any comminication.

If this is a DSL Gateway Router, check the settings on the modem and make sure that the DHCP server is enabled.
it woould be of great help if you could provide the exact model number of the Netopia modem so that I could check if there is configuration page which you can access and check the settings..
