What do you mean by ‘the Internet’s down’?
After you go through the normal steps of denial, rebooting, blaming your ISP, rebooting, cursing…. Check out these steps:
1. Before you do anything else, first restart your modem and then wait for it to come back online. Once that is done, restart your router.
2. If you don’t have a router, reboot your computer and then the cable modem.
3. Once all the modems lights are lit and the activity lights are blinking, the net should be back up. If all the lights do not come on, check that all your cables are secure and then call your ISP.
4. Open a new browser window and try to get the site: http://www.worldstart.com. If the site comes up, it is good. If not, continue reading.
5. Go to Start>Run and type in CMD
6. Type Ipconfig /all
7. Make note of your default gateway and DNS servers.
8. Ping your default gateway. Do you get a response?
9. Ping one of the DNS servers. Do you get a response?
10. Type ping www.worldstart.com. Do you get a response?
If all else fails, you could use traceroute to find out where you are getting stuck. Traceroute is a command which can show you the path a packet of information takes from your computer to one you specify. It will list all the routers it passes through until it reaches its destination, or fails to and is discarded. In addition to this, it will tell you how long each ‘hop’ from router to router takes. To do this, just go to Windows, select Start > Programs > Accessories > Command Prompt. When a window pops up, enter the word ‘tracert’, followed by a space, then the domain name. If it timed out after line 1, you would know there was a problem connecting to your ISP in which case you will not be able to access anything on the Internet. It is generally recommended that if you have a website that is unreachable, you should use both the traceroute and ping commands before you contact your ISP to complain. More often that not, there will be nothing your ISP or hosting company can do about it.
Similarly, there are a number of network issues where there are two DHCP servers giving out IP addresses. If you have a router, you need to make sure it is in the same internal range as the cable modem. If your ISP router is 192.168.1.1, make your router .2. And if possible, disable the DHCP on the original. That should do the trick most of the time.
Best of luck!
