ADSL help
Hi Rajee,
First of all once you get things up and running please remember to re-install Zone Alarm and your anti-virus software as you need them.
I have attached my own connection instructions below and they should work for any Windows ADSL connection if you follow them through. Depending on your computer experience they may be useful or not but I hope they help:
Connecting Windows to an ADSL supplier through a networked (ethernet) modem.
I don't know your particular setup so I'll make things general and you can fill in the missing parts as we go. I use Windows 2000 pro at home and XP pro at work so some of the default values I give here may be different for anyone on the home versions.
First disconnect your modem from the splitter and we'll get the computer and the modem talking.
You will need to login to the modem so you should have the username and password supplied in the manual. They should also give you a default Internet address (in the form xxx.xxx.xxx.xxx - mine is 192.168.1.1 which is pretty standard) so if you can find that so much the better. This is the address your windows box will use to go through to the Internet.
First check your Windows network settings as this is where it usually goes wrong. By default Windows/XP (Pro?) expects to get it's network address from a device on the local network (DHCP is the technical term here). If it can't get one it goes into a sulk and sets itself to 169.xxx.xxx.xxx or something which doesn't help.
Use Start -> run ->cmd which opens a small black window. Now type "ipconfig"
(when using the black command window you have to press "Enter" to execute the command).
What we want here is IP Address, Subnet Mask and Default Gateway settings.
Mine are 192.168.1.11, 255.255.255.0, 192.168.1.1 and are pretty standard.
If you have a 169 number or something else it means two things: you are not getting the ip address you need from your modem and you won't be able to connect to the modem as you are on different networks. To oversimplify here - if the first three sets of numbers 192.168.1 (for example) of your modem and your pc match and the Subnet Mask is 255.255.255.0 then the two will communicate.
If this is the case you can try a quick fix by typing:
ipconfig /release
and:
ipconfig /renew
This should cause your modem to give an address to your computer so
ipconfig
should show 192.168.1.xxx (assuming your modem uses the standard addressing)
You should now be able to access the modem and login using a web browser and the address
http://192.168.1.1 (these may be different for your modem - the manual will tell you)
If the release / renew didn't get you a new address you need to manually change the settings to match your modem default ones:
"Start -> Settings -> Network and Dial-up Connections" in 2000 pro (XP is probably different but you can use the Control Panel to get there).
You should see "Local Area Connection" or maybe "Lan adaptor" or something similar in the window and left clicking to highlight and right clicking to give a menu you should be able to select "Properties".
There should now be an item "Internet Protocol TCP/IP" which we want to open so double click and there are our settings. We have failed to get an IP address so we select use the following (remember these are common defaults - your modem may use different ones so read the manual)
IP Address 192.168.1.10 (the last number doesn't matter but don't use 0, 1 (which is the modem ) or 255 or above.
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.1 (your modem ethernet interface)
While you are here you can also set up DNS which resolves numbers to Internet names (for people) and the other way around (for computers). These settings are for opendns.com but you can substitute you ISP's numbers if you have them:
Primary DNS 208.67.222.222
Secondary DNS 208.67.220.220
OK all the open windows to save and close them (windows 2000 usually wants to reboot the system after these changes but it's just being a baby - ignore the reboot option.
Now you should be able to log into the modem by typing in the Default Gateway IP number in your web browser. If not go over the steps again and try to spot where things went wrong.
You now have a Windows box and a modem working on the same network which is two-thirds of the work.
I strongly recommend changing the default password on your modem as anyone with the same model knows it.
Now have a look at the features part - there should be something along the lines of "Firewall and NAT" - make sure these are selected as it's your best line of defence.
There should be a "connection" box or section where you set up the box to connect to your ADSL supplier. You should have all the settings you need from them so I won't cover this. Double check everything and save the settings.
Now connect your modem cable from the modem external interface to your ADSL splitter. From your computer you should now be able to use the modem control panel to make a connection to the ADSL box in your exchange (for me it's "Status -> Connection Status -> Connect"). The modem should now show the connection as live and you should be all set.
