Hi Taebo,
I'm making some assumptions about your configuration - please correct me if they are wrong;
You have:
Phone port with ADSL -> ADSL Modem -> Linksys router
- Linksys router -> computer1 via network cable
- Linksys router -> computer2 via wireless connection
and you would ideally like to also have:
- Linksys router -> computer3 (on Vista) via wireless connection
I'm also assuming computer1 has XP or similar for the purposes of testing your internet.
With network problems like this, I usually take a "check-each-link-in-the-chain" approach.
1. Check phone port/modem
a. Unplug your the modem from your phone port
b. Disconnect the power to your modem
c. Reconnect your modem to the phone port
d. Reconnect your modem power and switch on again
e. Check the lights on your modem are displaying as expected
2. Attempt to configure a working internet connection on 1 PC with the modem. I.e. Phone port with ADSL -> ADSL Modem -> computer1 via network cable
a. Plug you wired computer (I called it computer1 before) into your modem
b. Click Start, Settings, Control Panel, Switch to Classic View (if it's not already)
c. Open Network Connections
d. There should be a Local Area Connection connected
e. Right click the Local Area Connection and click Properties
f. Under "This connection uses the following items:" select Internet Protocol (TCP/IP)
f.2. Click Properties
g. Check Obtain IP address and DNS servers are set to automatically (unless your ISP has told you to set them otherwise)
h. Click OK and OK again
i. If you already have a connection to your ISP listed, attempt to connect.
j. If you cannot connect, check your username and password are correct. If you cannot connect after this, call your ISP and tell them about the problem.
If your internet is working, stop here and post a reply for the next step.
Otherwise (if there isn't a connection to your ISP already present)
Either call your ISP and ask them to talk you through setting up your connection again, or try it yourself like so;
3. Create an internet connection on computer1
a. In the Network Connection window, click File, New Connection
b. Click Next
c. Select Connect to Internet if it isn't already selected
d. Click Next
e. Select Set up my connection manually (you could use the CD option here if you like)
f. Click Next
g. Select Connect using a broadband connection that requires a username and password
h. Click Next
i. Enter your ISP name, click Next
j. Choose Anyone's use if it isn't already and Click Next again
k. Enter and double-check your username and password from your ISP for your broadband account. If these are wrong it won't connect
l. Click Next
m. Click Finish
n. You should be presented with a Connect dialog. If so, Click Connect otherwise, open the connection you just created from Network Connections and click Connect.
If your internet is working, stop here and post a reply for the next step.
Hope that helps to start with.
