A. NO CONNECTION
[/b][/u]

-when you cannot connect to the Internet

-after each step, check for browsing

Step 1: Powercycle and check connections

-turn off all computers that access the Internet in the home

-if you are connected through a router, power it down by disconnecting the power cord

-power down the cable modem by disconnecting the power cord

-let things sit offline for about a minute

-checked that the coax cable into the cable modem (like your TV cable, with the pin) is screwed in tightly

-check the network cable (ethernet like the big phone jack, or USB with two different ends) that goes from the cable modem to the next device (your computer, or a router if you are using one), and make sure it is connected securely

-*if you are wired to a router* check the network cable which runs from the router to your computer

-first return power to the cable modem, and let it sit about 2 minutes to initialize

  **Some common modems:

              Toshiba modem = wait for solid "cable" light

              Motorola Surfboard modem = wait for solid "online" light

              Thompson RCA modem = wait for solid "cable link" and "Internet" lights

              Ambit modem = wait for solid "sync" and "ready" lights

-if your modem lights do not come on properly, contact ISP

-if you are using a router, return power to it next and wait for it to initialize (if you're not sure, just wait 2 minutes)

-bring up your computer

Step 2: Check for a valid IP address

-open the command prompt by clicking start, clicking run, then typing cmd into the run box, click ok

-at the command line, type ipconfig

-windows may look to more than one connection, but you should see for one an entry called IP Address followed by a series of numbers

  *IP address rundown: Windows auto assign IP address (indicates no connection) = 169.254.x.x

                                    Router (network) IP address = 192.168.x.x <--issued by router

                                    Other IP address that begin in the 60's or 20's (among others) are valid

-if you have a valid IP, or are on a router with 192.168.x.x IP, and still cannot browse the Internet, go to the NO BROWSING section

-if your IP address is 169.254.x.x, continue here

Step 3: Turn off firewalls and antivirus

-turn off XP firewall by clicking start, control panel (if it says "switch to classic view" then click there), open "Windows Firewall", turn off

-look at your system tray (the icons by the clock in the bottom right), hover over each icon, if it is a firewall or antivirus then right-click it and choose exit, shut down or disable

Step 4: Check your network adapters

-click start, control panel, switch to classic view, open "System"

-click on the hardware tab, click on the button which reads "Device Manager"

-if the drivers for your network adapter are not installed properly (ie. there is a conflict), then it may be listed under "Other Devices"

-click the plus next to "Network Adapters"

-you should see your network adapter listed.  if there is an X over the symbol next to it, then right-click the adapter and choose "enable"

-the symbol should be green to indicate it is working properly

Step 5: Check your protocol settings

-click start, control panel, switch to classic view, open "Network Connections"

-if you are hard-wired, look to "Local Area Connection"; if you are wireless, look to "Wireless Connection"

-right-click your connection, choose properties

-under "this connection uses the following items" click to highlight "Internet Protocol (TCP/IP)"

-click properties

-set to: "obtain an IP address automatically"

-set to: "obtain DNS server address automatically"

Step 6: Restoring TCP/IP

-click start, click run

-type cmd and click ok

-type netsh int ip reset resetlog.txt and hit enter

-type exit on the next command line and hit enter

-click start, control panel, switch to classic view, open "Network Connections"

-if you are hard-wired, look to "Local Area Connection"; if you are wireless, look to "Wireless Connection"

-right-click your connection, choose properties

-click install

-choose protocol, click add

-click "have disk"

-where it says "copy manufacturer's files from" type c:windowsinf then click ok

-choose "Internet Protocol (TCP/IP)" and click ok

-close windows and restart computer

B. NO BROWSING

-when you have a valid IP address but cannot open web pages

-test for browsing after each step

[color=blue][b]Step 1: Scan for viruses and spyware[/b][/color]

-hopefully you are running antivirus and spyware protection programs.

-be sure to run a full system scan, one program at a time, and do not perform any other operations while these are running

-if you feel comfortable, you can also try the scan in safe mode for a more thorough scan

-if there are untreatable files, contact the vendor of the software for technical assistance

[color=blue][b]Step 2: Turn off firewalls and antivirus[/b][/color]

-turn off XP firewall by clicking start, control panel (if it says "switch to classic view" then click there), open "Windows Firewall", turn off

-look to your system tray (the icons by the clock in the bottom right), hover over each icon, if it is a firewall or antivirus then right-click it and choose exit, shut down or disable

-IMPORTANT: in the program permissions of your firewall, make sure that "Generic Host Process for WIN32" is not blocked.

[color=blue][b]Step 3: Ping command[/b][/color]

-click start, click run, type [b]cmd[/b]

-in the command window, type [b]ping www.testmy.net[/b]

-if the ping goes through, there will be a "ping statistics" line.  look for packet loss, and high round trip times

-if the ping is ok (no loss), proceed to Step 4: Restoring Browser Defaults

-if the ping says "unable to resolve host" or has 100% losses, try to ping by IP address

  -type [b]ping 67.18.179.85[/b] and hit enter, and check for packet losses

-if the ping by IP address is ok (no loss), try to browse by IP address: in the address bar of your browser, type 67.18.179.85...does testmy.net come up? If so, it is a DNS issue.  Proceed to Step 5: DNS Settings

-if ping by URL and ping by IP address both fail, proceed to Step 6: Restoring TCP/IP
