1.0 General(back)Each of the Motorola cable modems distributed these days has a built-in HTML interface, that allows you to view your cable modem signal levels, firmware, MAC Address, etc. This can be done by typing in the following IP Address into your browser's address field: »192.168.100.1 ... and poof!
Motorola SBG6580 Modem installed by Road Runner is defaluted to 192.168.0.1 for the HTML interface.

by drake edited by sashwa (back)You can do this by pointing your browser's address to: »192.168.10.1 - you will be prompt for user name and password. The user name and password should have been setup once you linked your router to the network, as part of the CD setup protocol. The CD should be labeled: Motorola Installation Wizard - Wireless Broadband Router WR850G (or WR850GP).

It is very important to keep the CD in a safe place, just in case you're unable to access the router, for any reason.

If your cable operator permits, you can give your them a call and ask for a update to your modem's firmware. Chances are, tech support will deny your request - but, it depends.
by drake edited by skj (back)Similar in appearance and features, the SB5101 & SB5120 are not repackaged versions of the SB5100.
last modified: 2005-09-22 15:40:48
The SB5100 uses the Broadcom chipset/processor BCM3348.
The SB5101 uses the Broadcom chipset/processor BCM3349.
The SB5120 uses the Texas Instrument chipset/processor TI4401.
Each modem has its own firmware versions unique to its model. All other product specifications are the same for all 3 models.
The SB5100 has been discontinued by Motorola, but support is available.
The SB5101 is a current model.
The SB5120 is being phased out.
You can add the SB5102 as well. It's the same as the SB5101 but it lacks the standby button and USB port.

2.0 Setting Up(back)Enabling WDS Mode on the Motorola WR850G Router (5.13 Firmware):
On Networking/DHCP Server Page, disable the DHCP Server on the Router being used as a repeater. Set the second unit to a LAN Private IP Address of 192.168.10.2, subnet mask to 255.255.255.0. (Make sure you adjust the DHCP Range on the Master Router to NOT include the .2 range, I would suggest setting the DHCP starting range on the Master Router to start at 192.168.10.10)
On WIRELESS BASIC Page:
Set both SSID's to the same thing (Capitalization and spaces counts)
Set both to the same channel.
Set both Operations Modes to the same thing (Compatibility 802.11b/g)
Hit APPLY Button at bottom of page.
On WIRELESS SECURITY Page:
Enable SSID Broadcast
Set ESS Authentication to "Open System"
Set Encryption Status to "None"
Disable "Wireless MAC Address Control"
Hit APPLY Button at bottom of page.
On WIRELESS ADVANCED Page:
Make sure Short Preamble and Frame Bursting are disabled.
Enable WDS Mode (on 4.03 firmware do not check this box as WDS is already enabled)
Enable WDS Restrict Mode
Enter the other routers WIRELESS MAC address in the others WDS Restrict MAC Address Area (Both routers have to have the others Wireless MAC entered here)
Hit APPLY Button at bottom of page.
RESTART UNITS (Recommend restart main router first, let it fully boot then power-up the second unit)
REMEMBER: The second (repeater) unit MUST be in radio range of the Main Router for this to work. It is recommended that you station the repeater in an area that has at LEAST a LOW to FAIR signal on your client machines, do not place it in locations that have a VERY LOW or non-existent signal.)
Once you have this working you can then turn on security. ONLY WEP is currently supported in WDS Mode (WPA will be supported in the new firmware). When you enable security it must be identical on both units (ESS Authentication and Encryption Status need to be identical, as well as the WEP Key). If you decide to enable "Wireless MAC Access Control List" on the Wireless/Security page, you must enter the Wireless MAC of each router in here as well as the Wireless MAC of any clients (in both routers).

by sashwa (back) WARNING: BEFORE YOU GO ANY FURTHER. FLASHING YOUR ROUTER WITH 3rd PARTY FIRMWARE MIGHT DAMAGE YOUR ROUTER, AND IT WOULD TAKE LOTS OF TWEAKING TO BRING IT BACK TO LIFE AT BEST. ALSO YOUR WARRANTY WILL BE WAIVED. FLASH AT YOUR OWN RISK.
last modified: 2005-02-15 16:47:11
With all the problems the WRT850G presents, some users might want to look for other options like OpenWrt firmware, based on Linux. So far users using OpenWrt firmware (fw) report superior performance and stability results. During this process make sure you use the LAN ports of the router and NOT the wireless.
Why you should NOT get involved with 3rd party fw:
• if you’re not familiar or at ease with using command lines
• if you need a GUI(web interface) to do your configurations
• if you’re not willing to do some research on how to use OpenWrt
• OpenWrt has a steep learning curve
• WEP it’s easy to get going, WPA takes some work.
• Last but not least if you plain and simple don’t know what you doing
• If any of the above apply to you, pray for the next Moto Fw miracle
So let’s do it. Have some chill pills ready, a bottle of patience and few shots of courage.
1. Downgrade your Motorola fw to version 4.03 using the GUI interface.
2. Reboot the router.
3. Download the OpenWrt fw from their site. Currently the latest ver. is 20050202
4. Extract the files. You’ll need the openwrt-linux.trx file. There is a folder called Packages which contains many goodies for your router, after you flash it
5. Then use the Moto fw bug and point your browser to:
6. Enter the following commands one at the time.
nvram set boot_wait=on
7. Reboot the router.
8. Now you’ll have to tftp your new fw into the device. You can use whatever TFTP clients you want. In XP you can use the following command, make sure you’re in the folder where you previously extracted the files from the command prompt:
tftp -i 192.168.10.1 put openwrt-linux.trx
(you might need a few tries if you don’t time it right)
9. After you flash, the router will automatically reboot and run the firstboot sequence which basically sets up your partitions and so on.
DO NOT REBOOT THE ROUTER DURING THIS TIME UNLESS YOU LOOK FOR TROUBLE
10. Wait until you can telnet into the LAN. The address should be 192.168.1.1 but in many cases some or all of the old configuration parameters from the Moto Fw might carry over. In which case obviously you’ll telnet into 192.168.10.1
11. You can reset your nvram with the following command:
mtd erase nvram
12. On OpenWrt documents and forum, you’ll find lots of help
ENJOY YOUR TRULY FUNCTIONUAL WIRELESS ROUTER
The router has a bridge between the LAN and the Wireless, so first you might want, for many reasons to break this bridge.
nvram set lan_ifname=vlan0
nvram unset lan_ifnames
Like this you have the LAN defined as vlan0, and obviously you can set your LAN as static or DHCP.
nvram set lan_proto=static
nvram set lan_ipaddr=192.168.10.1
nvram set lan_netmask=255.255.255.0
On WRT850G the wireless corresponds with eth1, so:
nvram set wifi_proto=static
nvram set wifi_ipaddr=192.168.11.1
nvram set wifi_netmask=255.255.255.0
Get the idea with braking the bridge now? Ok. Now let’s make this baby an AP and define the SSID:
nvram set wl0_mode=ap
nvram set wl0_ssid=ourgreatrouter
nvram set wl0_wep=on
nvram set wl0_key1=1234567890 ----whatever you want of course
On the WAN side of things you can go like the LAN, DHCP or static. I use static because of my network layout.
nvram set wan_proto=static
nvram set wan_ipaddr=192.168.1.1
nvram set wan_netmask=255.255.255.0
The default gateway: nvram set wan_gateway=192.168.1.2
And the WAN DNS: nvram set wan_dns=192.168.5.1 9 (as ex.)
Now just do nvram commit and reboot.
You should install dropbear (client/server SSH)
ipkg install dropbear
Reboot and make sure you can logon using SSH. AFTER that you could remove the Telnet portion altogether: rm /etc/init.d/S50telnet
So form now on, you’ll be able to do many things, and after all the frustration with the original fw, and after all this work, you have a fully functional router.
I tried to help you here, so you get a head start, so now you’re on your own.
We all should thank the great people participating in the OpenWrt community for making this possible.

3.0 Troubleshooting(back)One of the common causes for this is, having multiple machines in your home, and trying to access the router's page from each machine. Yes, it is possible to get to the router's access page, but during that period of time, no other system can login to the router.
So, how is this resolved? Quite simple, really. Just go to the machine that previously had the configuration page open, and there should be an option to log out on the left-hand side, click it:
That should do the trick. This should be done anytime you leave your machine, or whatever the case may be.
by drake edited by sashwa (back)This is quite a common issue that arises in most of our cable ISP forums. When placing a new PC onto a new cable modem, you need to make sure you've rebooted the modem for at least 30-seconds. The cable modem remembers the last MAC Address connected to it's WAN port. Rebooting it in the 30-second period should clear out the data stored within the modem, and allow other devices to connect.

by drake edited by sashwa (back)It depends. If your "PC Activity" light is blinking rapidly, then that's normal operation.
last modified: 2005-02-23 17:07:44
If your "Online/Receive/Send" lights are blinking, or just not on - then, there's something wrong. First thing you should check is your modem signal levels at »192.168.100.1/signal.html. You can check your signal levels here:
Afterwards, check your coaxial cables. Check your splitters, as well; make sure they are free of any crud, and the connectors are tight. Those are some basic things you should check. If the issue escalates - you might want to take a look into your local cable operators forum. Be sure to check their FAQs, too.
