Motorolla SBV4200 Cable Modem with AEX or iBook

Hi,
Got some problem here, I just got a new cable modem from motorola (SBV 4200) and am having a hard time configuring it. currently it's connected to a borrowed SMC router which works fine... I have an airport express router but i can't seem to get a proper connection. it's not giving a proper IP address (it gets 169.xxx.xxx.x). same thing when I connect my ibook... can't seem to get a valid IP.... what could be the problem?
thanks,
zurc

power cycling both devices solved this...

WRT54GS wireless Can't Through Motorolla SB5101 Cable Modem

I have a linksys wrt54gs wireless router. I have had it for almost 2 years, it has been hooked up to a DSL modem, no problems whatsoever. I just moved, and now have a Motorolla SB5101 cable modem.
I followed all of the steps exactly for setting up the router with a cable modem. Everything went smooth, when I check the status of the router, it has an IP address, everything's good. But I can't get online. The modem is fine, I'm hooked up right now via USB. The router is also fine, I can log into it and everything. All the lights are good on both the router and the modem. I downloaded and installed the latest firmware, I've power cycled, nothing. I know it has to be something simple, some setting somewhere.
Please help.

My troubles started after I upgraded my WRT54G V2.0 to the latest firmware. The download firmware file is prefixed with WRT54GV4.0_ which leads me to question if it is supported to run on my WRT54G V2.0 machine.
The full name of the firmware binary in the Zip archive is "WRT54GV4.0_4.21.1.US_code.bin". Please confirm or correct that this is the latest & greatest firmware version for my V2.0 WRT54G.
The problem presents itself as an in-ability to connect to ot ping any IP device past the RF side of the Motorola SBV5120 Cable Modem (also an older Motorola SB4100).
I use DHCP on the Modem with OOL's (Optimum On-Line) DHCP Server, in turn I use DHCP on the Router with the Modem as DHCP server and finally use the Router as DHCP Server for my home network desk top/laptop/printservers/USB wireless hubs. Either the Router's MAC address or my laptop's MAC Address is reported in the SBV5120's configuration as CPE device, depending on which is connected. I can always connect to the internet by cabling my laptop directly to the bodem's Ethernet port instead of the Router's WAN-Internet-Link port.
According to OOL tech Support, The SBV5120 and downstream devices do not care about which MAC addresses is used, just that one is present. Apparently the ability of spoofing to defeate MAC Address Filtering worked, so they don't do it any more (My guess - let me know if I'm right or wrong)
The modem log consistently reports success in completing the DHCP process and reports itself as operational. After a series of power cycle of both modem and router, I was finally able to connect to the internet through the router. This lasted about 28 hours. If I connect the IP LAN port of my laptop, I can connect to the internet.
At this point, I found the firmware alternative, dd-WRT, and replaced the LinkSys firmware with the dd-WRT firmware. Consistent ability to connect to the inter has been the result. The Latest LinkSys firmware is in question. I hope they have a plan to fix it. If not, I'm going to look very closely at the alternatives when it comes time to purchase 11n products.

Time Capsule 4 gen. with iMac OS X Lion 3 Windows PC (XP OS, Vista OS, Seven OS) cable modem with TC as Wi-Fi. Time Machine on iMac found TC for backup easily. Have Wi-Fi access on PC XP with Airport utility but cannot create TC.

Installed today Time Capsule 4 gen. with iMac OS X Lion. I also have 3 Windows PC (XP OS, Vista OS, Seven OS). Internet Access is cable modem with TC as Wi-Fi. Time Machine on iMac found TC for backup easily. Have Wi-Fi access on PC XP with Airport utility but cannot create TC. Does the Airport utility under Windows is way to access backup capabilities with TC ?

The TC is really just an external networked hard disk plus router.. you can access the hard disk and place files on it from any computer. You can backup any computer to the TC but it will have to use a backup software in windows.. there are literally thousands available. The built in msbackup is horrible.. but you can download lots of different software and buy then online for not a lot. Macrium Reflect has a free disk image backup, and when you pay for it includes incremental. I think disk images are well worth it, as they recover much better.. and their is a proper method of recovery using a boot cd.
BTW the TC space is not endless. And it is designed to hold a large number of incremental backups.. so anything you do in backing up several machines will make the number of backups limited. Remember you can also use a usb hard disk plugged in as a Network accessible disk. But it has to be formatted HFS+ or Fat32.. the later being highly undesirable.

Thanks! I use a Roko in my bedroom to watch baseball, Netflex etc., but in my family I have an Apple TV which cannot load either of the two.
I have not bought the AirPort Extreme yet, but will cable my cable company first.
Any other recommendations?

WRT54GS slamming Cable modem with Packets

I'm having trouble with my WRT54GS locking up my Cable Modem. TWC says its slamming the cable modem with too many packets. Is there any way to check this on my end? Full story below.
A little about my set up. I have Time Warner Cable business class Roadrunner service. 5 Static IPs. 4 being used at the moment. The Cable modem has a 4 port switch built in. Port 1 has a month or so old WRT54GS router v7 latest firmware (Gateway mode, Channel 6). Port 2 goes to my Sonicwall Barracuda them my internal network which also has WRT54GS router v7 latest firmware (Router mode, Channel 1). Both routers are sitting next to each other. Ports 3 & 4 have a Vonage Router hooked to each of them.
I started having trouble April 5 with the Internet being down that morning, then that night and falling morning. I power cycled the Cable modem to restore service. Called Time Warner Cable after the third reset. They told me that didn't see anything wrong from their end and I should call them when it is down. I did this and they said they would send someone out the next morning Friday. They came out on Friday morning and Checked cable which the tech said was fine so he replaced the Cable modem around 11:30. Fifteen minutes after he left the internet went down. I called TWC again. They did diagnostics on the cable modem from their end and saw that whatever was hooked up to port 1 was sent out 400 packets/sec. I think they said the cable modem could only handle 300. Port 1 is connect a WRT54GS v7 (latest firmware). We are using it for our Blackberries from Cincinnati Bell for WIFI and UMA service (like T-Mobiles @Home service) for VoWiFi. I turned off all the phones but the router was still slamming the modem with packets. I turned off the WiFi just in case someone hacked our WPA2 key. Still slamming the router with packets with only my laptop hardwired to it for setting up the router. I turned off the router and the modem wasn't getting hammered anymore. Port 2 which is my internal network was only up to 150 after open a lot of TV shows. Ports 3 & 4 nothing. I disconnected the WRT54GS hooked to Port 1.
15 minutes after I got off the phone with TWC internet goes down. They send out a tech on Saturday to check the line again. he sees a slight problem on the line but it should not be causing a problem which the first guy might have thought. But since I am having trouble he goes outside and checks the connections. He finds loose connection and a bad line cap (blocking cable TV). He fixes the connections and replaced the line cap. He comes back inside and rechecks the line. Everything is great no more fluxation of signal or packet loss. I hook the WRT54GS back but it still takes down the modem. So I figure that it's just bad. So I take the WRT54GS from my internal network and set it up to match the one for the Blackberries it's replace. I install a WAP54G on the internal network in it's place. I can't get my Blackberry to get a UMA connection and doing Google searched find this page
http://www.blackberryfaq.com/wiki/index.php/Linksys_Router_Tips
I set up my router and Assess point with the setting from the above except the channel setting leaving them on channel 6 & 1 so they don't interfere with each other. Set: Fragment Threshold : 2304 (256-2346), RTS Threshold : 2304 (0-2347) and Beacon Interval : 50 (20-1024 ms). I also Enable WMM QOS. My phone connects and internet seems to be staying up Saturday Evening. I come to work Sunday afternoon and Internet is still up. I check my phone I have UMA signal and everything is right with the world. 20 minutes later internet goes down. I unplug the WRT54GS and power cycle the cable modem. I am now waiting to see it the internet will stay up without any WRT54GS hooked up.
I have not had a problem before and both Linksys are not even 6 months old. I have read review were people have had trouble with the WRT54GS. Were some people have no trouble will other all kinds of trouble.

As you said cable connected to the pc is working fine!!...connect modem to the router WRT54GS...reset the router once (30 secs) in such a way that Power light on the router is blinking...power cycle complete network i.e., unplug modem & router power cable for 30 secs...plug in modem power cable once lights are solid green plug in the power cable to the router...its important that after upgrading firmware resetting the router is important...so try this & it should deifnately work.Do the wireless & advanced wireless settings as router is currently in default settings.
Also, you want to connect your access point WAP54G to the router & open the setup page of WAP54G using 192.168.1.245 do the wireless settings & try connecting to the wireless router & then check....should work.

How do I use a Netgear CM400 cable modem with my Time Capsule router?

I switched out my TWC modem for one I bought. I called and activated a CM400 Netgear modem with time Warner cable. They said it is activated and responding. My time capsule is on a green solid light but i can't connect to the Internet! Why??

Your previous setup may have been a modem router and the TC is connected in the wrong mode.. it should be dhcp and nat with a pure cable modem.. is it?
You also might need to put the TC into the correct mode.. then power off the modem for about 15min.. (try 5min first).. power up the modem.. wait 5min and then power up the TC .. it should grab the public IP and route that to the network.. reboot all the clients so they get fresh connection and see if that works.
If not give us a few screenshots from the airport utility of how the TC is setup.

* Share One Cable Modem with 2 Airport Networks ??? *

I'd like to have my one Motorola cable modem shared with an Airport Extreme G base station and an Airport N base station on 2 seperate Airport networks (G and N). Is this possible?
If not, if anybody has any ideas for a workaround, that would be great.
- thanks in advance.
Ted.

Yes.
Just connect the cable modem to the WAN port of the first AirPort Extreme base station (AEBS).
Then connect the WAN port of the 2nd AEBS to the LAN port of the first AEBS.
Configure the 2nd AEBS so that it is acting as a bridge (not distributing IP addresses).
You can find reference to this setup in threads describing a "dual-band" network. Also Apple's documentation describes this setup.

Multiple sites ASA's connected to Cable modems with same DHCP address

I have several locations with an ASA 5505 installed behind a cable modem. The cable modem is issuing DHCP for the same network address range in these locations. I have the outside interface obtaining DHCP from the cable moden network and the asa's are receiving the same outside address. I have the remotes set to use EZVPN to create the VPN tunnel back to the head end ASA 5540. I am seeing constant rekeying for phase 2 for those remote sites. is there any thing I can do short of assigning each asa a unique outside address?

Dave
The Linksys doing NAT is the reason why the ASA sees all the traffic as having source address as 192.168.2.1. The only way for the ASA to see the original 192.168.1.x address is to change the Linksys to not do NAT.
One thing that I notice is that there is not a route statement in what you posted for the 192.168.1.0 network. It is not clear whether the route does exist and you did not post it or whether the route does not exist. But if it does not exist it would certainly be a reason why you lose Internet connectivity when you change the Linksys to not perform NAT. (the ASA would have no knowledge of how to forward to the network and would drop all the traffic). Try adding the route to the ASA and changing the Linksys to not perform NAT and let us know if it works.

How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.

The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well.

Using cable modem with blu-ray player

I just had FiOS installed. I have a Samsung blu-ray player that's too far away such that wi-fi is not reliable.
Can I use a cable modem to gain access hard-wired? Since the STB has an IP address I take it I should be able to split the coax, feed it to a modem and then on to my blu-ray payer's CAT-5 port.
If this is possible what modems are compatible?
Thanks in advance for any assistance.

Your idea is sound, but instead of a cable modem what you need is a "Moca Adaptor". Something like THIS* . And when you split the cable, make sure that you use a high bandwidth splitter. Something like THIS* And then all should be good.
*Just examples

E3000 causes Motorola SBV4200 cable modem to repeatedly restart

Modem worked fine with Linksys G wireless router, but that router started locking up, needing rebooted. Replaced with E3000, now modem restarts while doing just about anything online. Time Warner (Roadrunner) said to take router out of line and call back if modem restarted. Removed router, and was able to play over a dozen YouTube and a half-dozen Hulu videos at once without the modem restarting. So I figure it has to be a setting for the E3000 that is causing the modem restarts. Looked through the advanced settings in Cisco Connect, but nothing jumped out at me. Suggestions appreciated.

Guess this will have to wait. Tried getting help via cisco.com, but the site keeps giving me error messages that it doesn't understand, or what I entered is too long, or the page I requested does not exist.

WRT54GS with Mac OS 10.6.8 and RCN cable modem not working

Hello,
I have a Linksys WRT54GS, version 6 with Mac OS X (version 10.6.8) hooked up to a Scientific Atlantic cable modem, with RCN as the ISP.
Recently, RCN had some network issues, and so I had to power down and reset my modem. The modem is working fine now -- no problems at all when the Mac is connected direclty to the modem.
The router's network is OK in that I can connect the Mac wirelessly to the network, but I can't connect to the internet through the router (through neither the wireless or wired connection).
I have downloaded the latest firmware update for the router, following the Linksys site instructions, but this has not helped me solve the problem.
Does anyone have any advice as to what I should do? I did call Linksys tech support on the advice of RCN, and they said that the router does appear to be working (power, WLAN, and Internet lights are on), but they would be charging me nearly the cost of a new router to fix the problem.
Any advice would be appreciated!

Since you upgraded the Router WRT54GS with the latest firmware so once reset the Router and power cycle the whole network… Then connect the Modem with Linksys Router on the Internet Port and then connect any one computer to any one of the Ethernet port on the Router [Numbered – 1, 2, 3 and 4]… Let me know the RCN connection is a DSL connection or cable connection…
So if you have a DSL connection you can refer to this link:
http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&login=1&vw=1&app=search&articleid=4020&userrole=Linksy...
So if you have a Cable Internet Connection you can refer to this link:
http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&vw=1&articleid=3686
As far as the wireless is concern:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page…
# Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
# Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
After doing the settings try to connect the preferred network on the wireless devices and check the connectivity….

Plug-in order for connecting to internet via AP Extreme with cable modem?

Help!
My internet's been a bit slow the past few days. I was scared to do anything because when I first got my Airport Extreme, it took me several days to figure out how to get connected, and it was highly frustrating. I remember that there was always a blinking orange light and some issue the utility couldn't identify, and the ultimate fix had something to do with unplugging and replugging my cable modem, but I'm not sure at what step in the process I did this.
Now, I tried unplugging and replugging the modem and though my base station was showing up in the list of networks under the Airport icon at the top of the screen, it kept saying there was an error when I tried to connect. Airport Utility wasn't even finding any base stations at all, so I tried several orders of unplug/replug to no avail. Each time, the green light was coming on but my computer couldn't find the base station and wouldn't connect to the network. I then tried the reset button (5 seconds). When I reset, the utility could find the base station, but I'm back to blinking amber and when I try to configure the base station, it says "the wireless network could not be found." Does anyone here know the magic order of the plugs? I'm using an Ethernet cable to connect from modem to base station and running Tiger on a Powerbook G4. Any help would really be appreciated!!

Is this a cable modem with a usb port? If so you are correct. It doesn't connect easily. You're better off with a modem that has an ethernet port. Now if you are referring to a Sprint Novatel U720 USB modem I can tell you it works.

WRT54G V6 strange problem with cable modem

I have a cable modem with Comcast Digital Voice. I have a WRT54G V6 with the latest firmware. After much discussion and troubleshooting on the phone with Linksys rep, I returned and swapped the router. No change to the problem. I've seen similar issues, but not exactly the same one, on this board. Here's the situation:
I have an XP computer connected via Ethernet directly to the router. I have 1 Mac Laptop (OSX) and 1 Thinkpad (XP) laptop that use the home network interimly via wireless. I use WEP, but no special filtering.
I can get everything set up fine, and all will work for some time. Like I've seen some other's say, about 30 - 90 minutes worth of online time, and the router seems to hang - BOTH wirless and wired. During this time, my wireless signal does not drop out. But I sudddenly cannot get to the internet.
What makes it especially odd is that my digital voice (VoIP) does NOT drop out, meaning my internet connection is still up (and the cable modem shows no signs of trouble - and a reset of the cable modem makes no difference by itself.
The only thing that fixes the situation is a hard restart of the router (meaning unplugging it and then plugging it back in).
The Linksys help folks had me do a complet reset of everything and then even had me change some parameters, including a change of channel, manual MTU, etc. Nada.... Then I changed the router to a new one... Same-o same-o.
I suppose the Cable Modem could have a bad ethernet port -but I read SO many things similar to this problem on the board that I doubt it.
And to think I dumped my NetGear!!! (It also had problems - that were associated with unstable wireless).
Any help is appreciated. It's a real pain.

One other thing... When it drops out, I cannot even get to the router admin page via my web browser and wired connection to the router. So perhaps this has something to do with DHCP server dieing?
