20 Most Recent Arris Touchstone 450a (CM450) Modem - Page 2 Questions & Answers

The 2 jacks on the back of the Arris modem are labeled "1/2" & "2". The first jack labeled "1/2" means that the jack is capable supporting 2 different phone numbers, a line 1 and a line 2. The second jack labeled "2" means that it is capable of supporting only a second phone number. Therefore your 1 phone number is working correctly from the port labeled "1/2".

There are different types of phone splitters. It is possible that the one you used may have been to split lines 1 & 2 on a single jack into two seperate jacks. Take a closer look at the splitter and see if the 2 ports are labeled differently.

Hope that helps.

Hi,

There could be a couple of causes for this issue. Your internet could be degraded when it gets to your house causing disconnects. You will have to contact your Internet Service Provider in order to have them resolve this issue. Normally, they will replace splitters and may even replace lines outside of your house. You could also be having problems with the modem directly. The may replace this. You could also try to upgrade the software on it. Click here for the update page for Arris.

Typically, I recommend you unplug the router, plug the computer directly in the modem and see if you still have the problem. If you still have the problem then you know it is just the modem. If the problem resolves itself then you know the most likely culprit is the router.

I would also recommend that you update your router firmware as well. Do a google search for the brand name of the router and go to the companies website, look in the support/downloads section for updated software.
--If possible, try a different Ethernet port on your router. You may have a bad port.
--Take out and reinsert all Ethernet cables on your network. Loose cables can cause disconnects.
--If possible, replace the Ethernet cables. Bad cables can cause this.

Lastly, you could be having an issue with the Network card(NIC) on your computer. Network cards are either built into the modem or external(a card you insert into the motherboard). Using the process of elimination and the steps above, you can hopefully narrow down the problem to one specific component of your network.

Yes you have to connect the ps3 to your modem unless you have a wireless modem and then you can configure your ps3 wirelessly.

Connect your router to computer with ethernet cable then you can access it with following default link. http://192.168.1.1 or http://192.168.0.1 or http://192.168.15.1 or http://192.168.2.1 If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it. Then it ask for user name and password. Type user as "admin" and password as "admin" or "password" or blank. Then you can see configuration page of router. If you are still not able to access it then press RESET button for 10 seconds it is in back side of router. Then all settings defaults then you can access it with default above ip. Let me know if you need further assistance.another aspect that could affect connectivity is by checking out the followingIf can you get the ip address of the computer you are using? if it starts with 168...., you may not be able to connect to internet,the right ip address should start with 192.168.2.2 to 192.168.2.100.here is a test , try to connect your computer direct to the modem, if you can connect, turn on the router reconnect the cable to the router , put back new cable to your computer, if you cant still browse the internet restart your pc, hope this help

If you are speaking of a network key on a router that is not your own then forget it.If you are speaking of your own router, check the documentation for instructions on how to reset it manually. This will clear all the information back to factory default, which included erasing any network keys.

Hi,If you are connecting to a router(gateway) that has wireless security enabled you will need to enter a security code on your PS3. I wrote a tech article which explains how you can obtain this security code, or if need be, set one up. Click link - How to obtain router security key,password-G33k

Hi, You would need something like a Dual Port Ethernet PCI card and this would be inserted into the motherboard. Click here for example of what I am talking about! Let me know if you have any questions.-G33k

There are a couple of options you can try. 1) Contact Arris directly for details on how to purchase this modem. 2) Try and see if this modem is located on eBay or any other auction site. *** I have not been able to find a site that sells this modem. But I have found people in a similar situation as yours. They have Comcast internet and instead of renting the modem they want to purchase, or upgrade. check out these two links. Here and Here Let me know if you have any additional comments. -G33k

when you are on Cable Internet with a "modem" only connected directly to the computer, what the ISP see is the computer's MAC Address (command prompt -> type ipconfig and hit enter).

put a router (which has it's own MAC Address) in-between and the ISP wont let you cause it sees the router not the computer.

check physical connection: cable modem -> router -> computer(hard wire for this troubleshooting)

access the d-link gui and locate the “Clone MAC Address" button (supposed to clone the computers MAC Address - verify if it's the same), save settings & reboot the router.
