Question about Arris SB6121 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem (612572180136)

Open Question

Do not know my password for my motorola surfboard SB6121, how do I get it?

Since this is a wireless router when I try to connect to the internet from my wireless lap top it shows me my network and asks me for a password to connect to it. It says if I do not know it, ask the owner for permission, the problem is I am the owner and all I want to do is use the wireless connection. No problem when I hard wire it or plug in only with wireless connections.

SOURCE: cable modem + dlink router

Your modem needs to be rebooted in order for your router to pull an IP from the modem. To do this, look for a little hole in the back of your modem and use a pen to push the button. Wait for the reboot to finish and then try again in about 20 seconds.

SOURCE: losing connection

I assume this is a cable modem? You need to call your cable company and have a trouble ticket created. I worked for the cable company installing cable for quite a while and I bet my paycheck the signal getting to the modem are below specs and that's why the modem gets dropping the internet connection.

Hope this helps.

Make sure that you have the ethernet cord from your modem plugged into the WAN/Internet port on your router. Then unplug the power cord from your cable modem and plug it right back in. After the modem fully comes back online, unplug the power cord on the wireless router and plug it back in. wait 30 - 60 sec and then try and connect.

Most cable companies only allow one active"CPE" at a time for internet access. All this means is when you change what is connected to the cable modem you must always reboot the cable modem to allow access.


Hope this helps. Let me know if it does not work.

SOURCE: Unable to set up wireless router

Shut down your computer, unplug the cable modem and the switch. Connect all three - computer to switch, switch to modem. Make sure that the ethernet cable between the router and the modem is in the router uplink port and that the computer is plugged into one of the four ports that look alike. Wait 30 seconds - plug in the modem. Wait another 30 seconds, plug in the router, wait another 30 seconds and boot the computer. Open a browser and see if you have internet access. If you still don't, then try to check the browser by typing 192.168.1.1 into the address bar of the browser. That should give you the browser sign in screen. The Linksys default is to leave the user name blank and type admin for the password. That should give you access to the router so you can check the settings. If this doesn't work, document carefully what happens and post again with your results and we'll try to go from there.

How do I find the bridge mode in sb6121


The Motorola Surfboard SB6121 is a cable modem only - no router included.

You must have a router - after the modem - in the network if you need router duties.

There is no bridge mode in the modem. Bridging the modem basically bypasses the routing function of the device and passes everything on to the next device in line......the router in this case.

Since this modem does not have a router built in - it is always in bridge mode.

Connect to it directly using a LAN cat 5 cable, not wireless.
Log in as admin to the router, and change the wireless password to something new.
Disconnect the cable then try connecting from each laptop by wireless, when it prompts for password enter the new password.

The wireless connection is not working. The only network that shows up is lynksis wich has a waek connection and asks for a password that i have neever had to use before, so i dont know what the password...


Unfortunately the Motorola SB5100 SURFboard is not a wireless device. The Linksys you are trying to connect to is most likely someone in your area and they have it password protected, which is why it is asking for a password.

In order to setup Wireless you will need to invest in a Linksys, Netgear, D-Link, or some other Wireless Router. They can be found at any computer store.

Once you have the wireless router you can connect an Ethernet cable from the Motorola SB5100 SURFboard to the Wireless Router. From there follow the instructions for the Wireless Router you purchased to set it up and secure it.

If this helps or solves the issue, please rate it and give a testimonial for my response.

Thank You,
Brandon

Trying to get my ps3 connected so i can get online


You need to disable the UPnP function on the Belkin router. Log into the router(192.168.2.1), and look under System Settings. If you haven't changed the password on the router, the default password is blank, i.e., no password.

Get to the security setting for my motorola sbg900


Bring up your internet browser, and in the address bar enter "192.168.0.1". This will bring up a page that asks for a password and username. The defaults are:

Username - "admin"
Password - "motorola"

From here click on the wireless option, then on security, and I would suggest using WEP, and throwing on encryption. Also you will probably want to click on the admin option at the far left to change your username and password, since if people know those security becomes a bit more pointless. Make sure you do not forget your new username and password, as you can probably see there are currently many people on this site with the problem of not remembering what they set it to. :)
