No network connection (has not previously worked)

Now enter the IP details in here that you were provided with. Then click Close/OK on all the windows to apply the settings.

Internet but no email

Cannot connect to a website
This may be due to a failure at the web site or remote computer you area trying to access.
- Try accessing a different web site or computer to see if your connection is working. If you can access other sites, then your network connection is not faulty. Try step number 2. If you cannot access other web sites, your computer's network connection would appear to be at fault. See the section above 'No Network Connection'.
- Try pinging the remote web site or remote computer. Go to Start > Run > cmd > press enter. In the window that appears, type "ping" followed by the address of the web site or computer you are trying to access. Press enter. If you see some replies appearing on the screen in the format "Reply from 22.214.171.124: bytes=32 time<1ms TTL=254" then the remote site is alive and receiving requests. If you see a message saying the "Request timed out" then either the remote host is not responding or ping requests may be blocked to that host. If you have tried step 1 in this section and you are able to access other web sites and computers, it is most likely that the web site you are trying to load is having problems or that there is a problem with the remote computer you are accessing, try again in a while.
