Question about Arris SURFboard SB5120 Modem

1 Answer

I can't get ports open on my surfboard 5120 modem, the router is configured properly and it showed them open when I first set it up but they closed and now I can't get them to open again. Once after switching modems it worked briefly but I think the router updated itself or something and the ports are now closed again

    also this modem has no port forwarding functionality, as it is just a passthrough modem, meaning any connection wanting through does, if ports are closed it is either a service provider issue or a firewall issue on whatever device needs the ports

Globe symbol won't turn green.


I was banging my head for 2 days with about 35 different configurations and finally tried the following and it worked just fine. Also, tried connecting 3 computers and they all connected with "NO" issues. Even connected wireless with "NO" issues. Now I am at 20mb download speed...J compared to AT&T 1.5mb download speed.

This is my DLINK model -> (DIR-601 Wireless N 150 Home Router Wireless router)


1. Reset your Comcast Surfboard Cable Modem by unplugging it for 5 minutes.

2. Then reset your DLINK Router to the manufactures default settings. Then Unplug DLINK Router for 1 minute then plug it back in (Just plug your cat5 cable into port 1 and connect it to your computer) there should not be anything else plugged into the DLINK Router at the time you make the changes. Just 1 computer can be connected.

3. Went into the DLINK configuration 192.168.0.1 and changed the PPPOE setting that I was using for my AT&T Modem to Dynamic IP (DHCP). Once you make the changes save them and then unplug your DLINK Router it's off.

4. Turn on Comcast Surfboard Cable Modem and wait until all lights are on. Now plug in a cat5 cable from the Surfboard Comcast modem (NOT A CROSSOVER CABLE LIKE THE CD INDICATES) to the INTERNET port of your DLINK Router. Now turn on your DLINK router.

5. Then turn on your computers or restart them and it will pick up IP Addresses from your DLINK Router

Motorola router nat not open for xbox live


Configuring the Firewall for Gaming
By default, the SBG900 firewall is disabled.
If, as recommended, you enable the firewall, refer to the game’s documentation to ensure that the necessary ports are open for use by that game.
The pre-defined SBG firewall policies affect X-Box LiveTM as follows:
LOW: XBox Live data can pass through the firewall. No user action is required.
MEDIUM or HIGH: To enable X-Box Live traffic to pass, you must configure:
• Choose Custom on the Firewall > POLICY — basic Page • UDP 88:88 and UDP/TCP 3074:3074 on the Firewall > POLICY — advanced Page
Configuring Port Triggers
Because the SBG has pre-defined port triggers for games using any of the following applications, no user action is required to enable them:
• DirectX 7 and DirectX 8 • MSN Games by Zone.com • Battle.net®
For a list of games supported by Battle.net, visit http://www.battle.net.
You may need to create custom port triggers to enable other games to operate properly. If you set custom port triggers and enable the firewall, you must customize the firewall to allow traffic through those ports.
To create custom port triggers, use the Gateway > PORT TRIGGERS — custom Page.

SB900 USER GUIDE
The motorola guide has more information relating to port triggers.
If you download the pdf file, go to page 27 for Firewall settings and Page 35 for Gaming Settings..
More indepth information is there.
Hope that helps
Mike

4. Power on the modem and wait for the lights, then power on the router.
RECONFIGURE:
1. Open the browser (Internet Explorer, Mozilla Firefox or Safari).
2. Access the router, usually with http://192.168.0.1
3. Login to the router with the Username as "admin" and Password as "password" (please note that the Username and Password are case sensitive).
4. Click on 'Basic settings' from the left menu and select 'Use Computers MAC Address' from 'router MAC Address' section.
5. Click Apply.

Cant lock my signal was trying to find a alternative way because i lost the disk??? i have a SBG 900 and any one can get on my internet signal


There's another option to configure the security or encryption using your SBG 900

Connect your computer to one of the LAN ports
Access the configuration of the modem (example 192.168.254.1)
The if you got the configuration page open find the wireless settings and configure the WPA or WEP security using your modem.

Surfboard Cablemodem not communicating with Belkin Wireless Routr


If the modem is actually passing out DHCP, then you have to connect the modem to the router 4 port lan side and not the wan port. Give the router a static ip like 192.168.1.2 and you can talk to it and configure the wireless features.

I HAVE A LINKSYS WRT54G AND A MOTOROLA SURFBOARD SB5101.IT IS A CABLE MODEM.MY LINKSYS PROGRAM ESTABLISHES EVERYTHING BUT INTERNET CONNECTION EVEN THOUGH I AM ON THE INTERNET NOW.CAN YOU HELP GUIDE ME...


The easiest way to fix this problem is to not use the software CD that came with you WRT54G. If you type in the ip address of the router (usually for this model the default is 192.168.1.1) in the web browser, you should come to the firmware on the router. After that, log in to the router (usually the user name is admin and the password is either blank or admin). This will show you all of the configurations for the router. Make sure on the first page you have your router set up as DHCP. This will have the modem give your "router" an ip address from your cable company. From there you can set up you router your self.
