Re: how do i connect a Linksys wrt54g2 to a arris cm450a
Your modem is capable of linking up to a router. What you do is take an ethernet cable and run it form the internet port on your modem to the internet/wan port on your router. From there you connect your pc's into the LAN ports on the router (typically labeled 1-5) if they are hardwired or you connect wirelessly with your laptop. You need to also power cycle/reset your modem when you plug your router in.

Disconnect the coaxial cable from the Arris.
Turn the Arris off.
Connect an Ethernet cable from your computer to the Arris.
Turn the Arris on.
Turn on (or reboot) your computer.
Open a command-line prompt on your computer.
Enter 'IPCONFIG' to see the IP-address of the "default gateway".
Open your web-browser, and type that IP-address into your web-browser, to access the configuration-page of the Arris.
Configure the Arris.
Turn the Arris off.
Connect the coaxial cable.
Turn the Arris on.
Reboot your computer.
When you did the initial setup for your router, you should have configured the wireless adapter in the router:
* set a SSID -- the "name" of the network
* set an encryption-level -- hint: use 'WPA' or 'WPA2'
* set a password for your network
It's that SSID/password that you need to enter on the DSI, to make a wireless connection to your router.
If your modem is not communicating with your Linksys router, your Arris modem was most likely installed directly to a PC or Mac when either you or a technician installed it. As soon as it connected it registered your MAC address from your NIC. You need to make your sure that the modem is still talking to the PC or Mac. Please try the steps below.
1. Find out what your NIC's MAC is (go to "Start", "run", "CMD", "ipconfig/all")
2. Copy down your NIC's "Physical Address." That is the MAC.
3. Go into your router's web based utility (Linksys is 192.168.1.1, username:none ; pw: admin) and click on the "Advanced" tab.
4. Then click on the "MAC Address Clone" tab.
5. Type in the number that you copied down. Click "Apply."
6. Now power cycle your Modem while it is disconnected from your computer and router. Power Cycle the router. After everything has rebooted connect the router to the modem and you should be good to go!
In most cases, this should work, and you ought to have internet access now.
If this did not work, the following is a quick fix: 1. Go to the 'Applications & Gaming' tab 2. Click the sub-heading 'DMZ' 3. Click 'Enable'. 4. Click 'Save settings'. 5. Wait for the settings to save, and click 'Continue'.
If this doesn't work, I would recommend calling your cable ISP and telling them that you need a modem that will work with more than one computer, or you need them to send a tech out who is able to set up the internet through a router.
You will need to purchase a router my friend. The arris does not have a DHCP server built in and cannot assign IP addresses to the work stations. The only way that could work is if you ISP provided you with a second IP address, which would also be extremely unsafe from a security standpoint. Any wireless router should do the trick.
All routers will only work with ethernet. You would need to get an ethernet card installed in your computer. You can probably buy one for about 20.00 at Walmart. If you don't want to do this you can purchase a usb/ethernet adapter and still use the usb port on your computer. You can purchase one of these for around 5.00's on ebay. Just go to ebay and search for usb/ethernet adapter. Please rate if this has helped. Thanks.
Most cable company's will not allow you to use the USB and the ethernet connection at the same time. You will need to only use ethernet to your PC and your XBOX. Once you have the ethernet cord connected from your modem to the WAN/Internet port on your router you will need to press the reset button on the back of the arris to authorise the router for access. After that is done you will plug you XBOX into 1 of the 4 numbered ports on the router. Then you will need an additional ethernet cord for your PC.
1).turn off the modem and the router.disconnected from the Internet ISP. and the computer.
2).disconnect the router from the modem.
3).turn on the modem.
4).connect the router to the modem, and turn on the router.
5).connected the computer to the router, adn turn on the computer.
if you are using wireless, waited about 5 minutes before turning it on.
goto control panel>>wireless network, and configure the wireless seting.
