your modem is Linksys WAG200G.
Its builtin ADSL 2/2+ modem and wouter with 4 lan ports and wifi capabilities.
You dont need to have splitter to setup the connection but incoming call will disconnect the net if you dont have the splitter so better you have it.
Now the setup.
Firstly connect the power cable.
Connect the phone line.
Connect the router to Pc via lan (put one end to port no. 1 on router and one end on lan card of the pc.)
As the router does not have power switch it will go on straight away you put on the main switch.
Go to Setup a new connection wizard (in connect to menu)
select setup an internet connection option then
select setup my connection manually then
select connect using Broadband connection that requires username and password for connecting then
provide the ISP name in next page then
Provide the user name and password lastly click finish.
NOw your connection in PC is ready.
You need to put up a few numbers in.
right click on the icon of the connection you just created above.
click on properties.
click on networking
select the tcp/ip option then click on properties.
here you need to select the option of get the ip address automatically. and get the dns address automatically, click on ok twice and you are through.
Now open internet explorer
type 192.168.1.1 press enter
it will ask for username and password which is admin / admin by default.
after that you will be taken to setup page of your modem.
In the menu there is first option Setup and first supoption basic setup.
Put the options as below :
Encapsulation : RFC **** PPPoE
Multiplexing : LLC
Qos Type : UBR
Autodetect : Disabled
Virtual Circuit : 0 VPI and 35 VCI
Dsl Modulation : G.dmt
Put in your user name and password
Local IP address 192.168.1.1
Subnet Mask 255.255.255.0
DHCP server : enabled
Starting IP address 192.168.1.100
Maximum Number of Users : anything between 1-99
Now you need DNS servers of your area.
get it from your friend/ relative / neighbour
Primary or Static DNS 1
Secondary or Static DNS 2
Time Date:
(GMT +5.00) Pakistan, Russia (they dont have option of India here
)
Now second option DDNS disabled.
Third Option Advance routing
NAT ; enabled
RIP : disabled
These are your basic settings, now you can save settings and when confirmed allow the modem to reboot and you are ready to go.
Now if you are going to use wifi or not gonna use it you have to setup security options and restrict the access. that we will deal later after you successfully setup the router.
Hope this helped.
PS : i have the same router and these are the setting which work for me i hope it also works for you. Otherwise there are more experts here to help you out
