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.

I need the wep security code for my sons dsi to download games on it from the internet. router name arris model # cm450a

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.

Does it mean my adapter is bad if it just stays lite up green and doesn't flash to try & connect to the internet? I installed everything correctly but it still isn't working. Any ideas? I have a belkin...

The Linksys adapter should have a program you open to find and connect to your router. If not, you can use the Windows Network settings to find your router and connect. Although 54G is a slower speed, they should still connect.

Wireless will not connect to internet after installing XP Service Pack 3. Router is a Linksys WRT54G2, adapter is a Linksys WMP11. Router is set to "mixed".

Try upgrading the firmware for your routher and the linksys WMP11. Also try setting router to 802.11g instead of mixed to see if it connects.

/Sometimes you have to call the cable company and they will reset the modem online for you. After you have done the whole powercycle bit, you have to restart the computer. Make sure all the other computers or laptops are shut off when you reset.

Linksys wireless router has many bugs: connection issues like no connection or constantly having to reset the router. It isn't compatible with many network adapters2.gif. Hope this helps!

Unable to connect Linksys wireless router to my arris cm450a

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.

No driver for my modem

There are no drivers for the arris cable modem unless you are using USB.

If you are using ethernet then it is simply plug and play. You may need to press the reset button on your arris.

Thank you.

Linksys wireless adapter and linksys wrt54g2 router not seeing each other

its possible that the wireless card does not have the correct wireless settings.

Open the linksys wireless monitor on your wife's laptop.
Go to the profiles tab, highlight the default SSID then click on edit at the bottom. It will search for the wireless network, from the list of networks that it will show you, click the name of your wireless network, in if the network is secured you will be ask to put in your network key. Then click connect. Then it will say that you profile was successfully configured. then click connect to network. It will take you back back to the screen where you saw no association to the access point, check if you will now get a new message. On that same screen click the more info button at the upper left hand side. Check the IP address it should be 192.168.1.x. If you have that IP then you can test if you will be albe to get online.

if you still have any problem just reply to this post.
