Because there seems to be no good complete step by step guide to setup a Linksys router on Comcast, I am posting this:
To setup a WRT 54 G v.5 on Comcast do the following”
Prepare ROUTER-
Perform a 30-30-30 reset by holding the little reset button in on the back of the ROUTER next to WAN port for 30 seconds, then continuiously hold it down unplug power cord, hold for another 30 seconds, then while you continue to hold the reset switch in , plug ROUTER back in powering the unit up. The 30-30-30 reset is done while CONTIUALLY holding the reset button in for 1.5 minutes ie, -30-30-30
This will set IP address for your ROUTER to 192.168.1.1
It will also blank the user and set the password to “ admin ”
Like this:
USER: _______________________
PASSWORD:_____admin_______
Now for your COMCAST MODEM
Plug your computer directly in to the Comcast modem.
Power up your MODEM
Open a command prompt. By going to START- RUN and type CMD
A little black screen should then pop up.
Type “ IPCONFIG /RELEASE “
Then type “ IPCONFIG /RENEW “
Wait about 1 minute
The computer should then be connected to the internet.
If not power off and on the modem and repeat Ipconfig commands.
If you do not connect check to see if the switch on the front of the modem is not in the off position. Whne it connects you should have2 lights on all the time, and 2 that flash on and off very quickly.
Now at this point:
Make sure your LINKSYS ROUTER is unplugged before this next step.
Unplug CAT 5 cable from PC that is going to the COMCAST MODEM and plug it in to the WAN, very important.. WAN port of the ROUTER. This is the port all to it self.
Plug another CAT 5 in to any of the OTHER ports on the LINKSYS ROUTER that are NOT WAN Ports1-2-3 or 4
Now power on the LINKSYS ROUTER by plugging the power cord in.
Open a web browser Internet Explorer or Firefox, or what ever you prefer, and type 192.168.1.1 . This is the IP address for your router.
Now you should be looking at your routers Interface page.
Click on the “SETUP” tab.
The setup for this page looks like this:
It should look like this:
AUTOMATIC CONFIGURATRION—DHCP
MTU; AUTO
NOW Set --- Local IP Address to 192.168.1.2 (assuming that address is not currently being used)
Subnet mask: 255.255.255.0 (should be set)
DHCP server: ENABLED (should be set)
This should be all ready set, except IP address, which you may, or may not need to change.
Now for the most important part.
Click on the “MAC Address Clone” tab.
Select ENABLE
Click “ CLONE PC”S MAC”
This in effect put your PC’S MAC in to the router.
IF YOU HAVE YOUR MODEM PLUGGED IN TO THE WAN PORT!!
Otherwise, it wont work because the Comcast modem sees all the MACS connected to the LAN ports. MASK does not work connected to LANS.
SAVE
Now click on the “Advanced Routing” tab.
Make sure “Gateway” is selected by Operating mode. (not “Router”)
SAVE
Now click on the “STATUS” tab.
You should see something like this:
67.175.145.87
Subnet Mask:
255.255.252.0
Default Gateway:
67.175.144.1
DNS 1:
75.75.75.75
DNS 2:
75.75.76.76
If it does not show some numbers then at the bottom of the page:
Click DHCP RELEASE
THE DHCP RENEW
You should now be able to surf the net on your WIFI if you desire. Or you could stay wired if you like.
Happy surfing!
