Question about Arris Touchstone 450a (CM450) Modem

1 Answer

Bad relationship between Modem and Wireless Router.

Here is my problem, it is a bit confusing and hard to explain but stay with me:

Alright, I have a touchstone telephony modem that wont connect to a Netgear wireless N router.

The part that is hard to understand is that the two function fine with other PC's and Consoles but not with each other.

For starters I am getting all of this info from two different setups, however I DO bring my Xbox 360 and Wireless router to both establishments.

I hope this diagram will help to diagnose this problem.

HM-home modem
FM-foreign PC
WR-wireless router
HPC-home PC
FPC-foregin PC
XBX-xbox 360
(~)-wireless connection


FM-WR no
FM-XBX yes
FM-FPC yes (using to make messege)

3-4 weeks ago every thing was all yes.

Because of the mere fact that it changed so suddenly over time I feel as though it is my fault and not the hardware's.(i.e A question more suited for Shelock Holmes than the Geek Squad.)

Please help as soon as possible and please tell me if I am leaving out anything major.

Thank you for reading :)- C.R.

Trying to understand the connections. It looks like the problem is FM-WR. Everything else works. Are you powering everything off when you move the router from one modem to the other?

I have at@t dsl ppoe service trying to connect my dlink dir 655 and a bit confused on why it will not work

I use same router at my house and a ADSL2 modem. I put the modem as bridge and enter password and login at the router. Use the wizard configuration of the router and it should be easily done.
If you have the wireless computer with G/N try to use a high channel (>9) for the wireless and avoid this way problems with other existent wireless networkS on your area.
Hope it helps.

Trying to hook up a dlink router using cricket broadband wireless modem. need help?!?!?

Cable-modem (or DSL-modem) --> WAN port on CRICKET

and you _have_ a wireless network, without using the D-Link.

If you really want to get yourself confused:

LAN port on Cricket <--- Ethernet "cross-over" cable ---> WAN port on D-Link router.

I have a DSL502T ADSL Router,and have bought a new emachines computer. I can not connect to the internet. The computer has a wireless connection loaded but I want to connect by dailup Please could you help...

You are a bit confused with the various components required for Internet connections.
If you have a dial-up connection with an Internet Service Provider, all you do is connect your computer's modem port to the phone line and dial the phone number of your Internet Service provider.
If you are connected to the Internet Servise Provider by ADSL and have a combined ADSL router and modem then you connect the phone line to this router/modem. If the ADSL modem is separate component then the phone line is connected to the ADSL modem and this modem is connected to the router with a LAN cable and the computer is connected to the router with another LAN cable. If the route is wireless and the computer has a wireless card then you don't need a LAN cable between the router and the computer.
If you are connected to the Internet by ADSL, to secure your Internet connection and configure your computer so it can connect to the Internet, please follow my instruction - click on this link :-

SMC2804WBR router: The lights are on but nobody's home.

Sounds like the router is about to die. I had the same issue with a wireless router a few years ago. It would broadcast but I would not be able to get onto the wireless no matter what I did but plugging straight into the modem and it worked just fine. If you've done a hard reset and it is still not connecting or staying connected, it is about time to replace the router.

Wireless connection problem


Ok...I am a bit confused. You must have a modem to connect to the internet...whether you are broadband (cable/DSL/wireless), Dial-up or T-1 or higher (TSU/DSU).

This is how it should run once you are sure you have the modem... router...pc to router. If you have no router...then plug ethernet cable from your modem to your NIC card on PC.

You will have to make sure your network card is working (check for flashing green light and one solid green. Then you can goto COntrol panel and run the wizard to connect to the should work.

What kind of router do you have? Also, what is the model number of your modem?

Let me know if I can help further.

Good luck my friend.

DGL-4300 resets every few seconds

Try the following:
1. Hook up your router like you want it to be
2. After the WAN/Wireless lights turn off we want to HARDRESET your router.
3. There will be a small hole that requires a pen or paper clip to press...Hold this down for about 15 seconds, or untill the power light flashes on your router.

This might take care of it.

let me know.
