Routers / Switches :: Intermitted Internet Connection With New Motorola SurfBoard 6121?

Jun 15, 2012

Motorola Surfboard 6121, Every since Com-cast has updated their network (two months ago), my Internet connection is VERY unstable.Com-cast says it is my problem because I can get reliable service at high speed using just my laptop: Win 7, and the Motorola modem. The modem does show high speed connection (blue light) when the only thing connected is the laptop.If I connect the rest of the home network; ,LinkSys BEFSR11 router, Netgear FS #108 10/100 switch, then my laptop. The Surfboard modems light turns orange (lower connection speeds). do I need to replace my NetGear switch and my router? This constant up and down intermittent connection is terrible!

Netgear WNDR3700 And Motorola 6121 - Lag Spikes From Connection

Oct 31, 2012

I have Comcast cable and prior to a couple days ago, it has always been smooth @ 36mbps download and 5mbps upload. I have a Netgear WNDR3700 and Motorola 6121 connected to my PC via Ethernet cable. Up until a couple days ago, I've been getting lag spikes where my games would completely freeze for a good 2-3 seconds and resume, as if the entire connection dropped and reconnected. I did a speedtest and I was getting around 4mbps download and 1-2mbps upload with huge fluctuation in speed.

I called Comcast and they said they were seeing a "red" signal error from their end so they sent out a tech to my house. He came over, changed some cables outside because they were corroded and that's about all he did. I tested my connection while he was still there and I was again getting 36mbps download and 5mbps upload. It was a quick 1-2 test so everything seemed normal until I started to see lag in games again.

I am getting the same lag spikes, albeit it's not as bad as before but it's still pretty annoying. Using speedtests, I am still getting 36mbps download but the graphs show that there are inconsistencies where there would be sudden drops in speed and picks back up still to show 36mbps. These drops are what I assume are the lag spikes. The upload is also suffering now, dropping down to 2-3mbps and it takes the test about 20-30seconds to load the upload portion of the test. Even loading web pages, sometimes it locks up for a few seconds longer than it should, which is normally instantaneous.

I have tried connecting my PC directly to the modem to bypass the router and am still getting the same lag, probably a little LESS but still the lag is there. My router is has always been updated to the latest firmware.

Motorola Surfboard Sb5101 Modem / Random Connection Drops?

Mar 5, 2011

I have a Motorola surfboard sb5101. Provider is comcast.I have never had any problem with my equipment until now. Here is whats going on. I bought a used sb5101 a week ago so that I would not have to pay the rental fee anymore. Comcast activated it, and it worked fine for a week or two. The other night I got disconnected from XBOX live randomly in the middle of a game. Thought maybe just a hickup, no biggie. Well it happened 3 more times in a few hours, then again the next day.So thinking maybe this used modem is bad, I plugged back in the rental from comcast which I still had. Worked fine for a while, then the same thing, random dissconnects after 10 min, 30 min, 2 hrs into a game...etcOn both modems, the 1st and 4th green light are solid, the 2nd and 3rd green light are flashing when the connection from LIVE drops.So I'm starting to think know that neither of the modems are bad. I then try going directly to the modem instead of the router, never had any problems with the router but figured I try.I even went into the attic and got rid of the 4 way splitter that feeds cable into all the bedrooms and put in a 2 way instead hooking up only the cable line im using for xbox. Thought maybe the signal is getting degraded to bad, eventhough never had a problem before.So now I'm practically hooked up right to the line coming off the street, ethernet cord plugged directly into the modem, no router. Still dropping connections randomly with same 2nd and 3rd light flashing.The connection needs to be completely stable for multiple hours.Also, I called comcast when I had to reactivate the rental modem, so they did refreshed that modem and reactivate it, but still had the disconnects the next day.

Use Motorola Surfboard SB5120 USB Port To Supply Internet To AVR?

Feb 12, 2012

I have a Surfboard 5120, which has both Ethernet and USB ports. According to the manual, a different PC (or, in the case of the Ethernet port, PC or switch) can be connected to each.

The ethernet port is already connected via a long, in-wall RJ-45 line to a Netgear wireless router elsewhere in the house.

As of yesterday, sitting next to the Surfboard I now have a network-ready Onkyo AVR (audio-visual receiver) with Ethernet port. I am wondering if I can use a simple USB to Ethernet connector to provide internet to the Onkyo. I am not very network savvy and don't know if the AVR would be able to connect okay.

My "network savvy" is so bad that I will probably screw it up if I were to connect the cable modem's single ethernet port to a switch, and then attempt to connect that switch to both the Netgear wireless route and also the Onkyo AVR (assign IP addresses etc).

Motorola SURFboard Extreme Cable Modem Is Connected But No Internet Access

Nov 7, 2012

Today I purchased a Motorola SURFboard extreme Cable Modem DOCSIS 3.0 in order to replace my old modem which is out of date and has been very slow as of late. I connected the coaxial cable, Ethernet cable(to Linksys wireless router), and power expecting it to simply work. All four lights came on green (power, downstream, upstream, connectivity). The downstream light turned blue which indicates a bonded connection.The device light was blinking on the modem. I connected to my wireless router, but no internet access. I then tried connecting my laptop to the modem directly via Ethernet cable, still no access. I think that rules out the router being the problem. I also ruled out my laptop being the problem as the same thing is occurring with my other laptop and desktop. I called my ISP (Cox Cable) and had them re-establish connection with my modem, this did nothing. I thought for sure this meant I had purchased a faulty modem; I hooked up my old modem and the results were the same, the modem connected fully with no problem (all four lights were green) but I have no internet access.

Motorola Surfboard Running Non-encrypted?

Mar 4, 2012

The only way we can use our Motorola router is unencrypted. I have gone into the router numerous times and reset it, unplugged it, retyped the WEP key, tried to shift to WPA and nothing works. None of three computers in the house will connect unless all encryption is off. We live in a good neighborhood on a cul de sac, don't get a lot of traffic through here, and know the immediate neighbors, but nothing is stopping a stranger with a laptop from sitting on the street and using our wifi. I've talked to the Comcast tech. The trouble just seems to be our boxes won't get past the WEP encryption stage.

Motorola Surfboard SB6120 Modem / Can't Get PC To Connect To Broadband

Jun 22, 2011

I can't get my PC to connect to my broadband. I am running windows 7 64 bit and use the following:

Motorola Surfboard SB6120 modem;
NetGear WGR614 wireless router

I am able to connect with other devices (iPhone, Roku) to my wireless through the wireless router. My computer recognizes the broadband connection, but it won't connect to it. I get two errors when I try to connect:651: the modem has reported an error, and 638: the remote server is not responding in a timely fashion.I have tried connecting the ethernet cable directly to the modem, but I get the same results.Also, I have tried to cycle down the computer, router, then modem and turn them back on in reverse with no change in results.The connection worked until I clicked "disable connection" one day when I had trouble connecting (high traffic i think). Since then, the"home group" I set up originally with the connection wizard disappeared, and it had not been able to connect since then. When I try to connect I click on a small icon in the lower right that says, "not connected, connection available", then I click on the button to connect to broadband and get the errors described above.

Motorola Surfboard's DHCP - Windows 7 Not Receiving IP From Device

Dec 4, 2012

I have a SB6121 Motorola Modem for my Comcast Service.The modem is supposed to give out an ip range of 192.168.100.11-40When I reboot the modem I temporarily get a 192.168.100.12 IP address but then somehow it changes to a 68.42.83.47 ip.I can't get it to stick on the 192.168.100.x network so I can't access anything.Before I had my pc connected to a Netgear Router which received the internet from the SB6121 but I am needing to troubleshoot some issues with a freePBX server so I plugged straight into the gateway.

Compatible Access Point For Motorola SURFBoard 6580?

Mar 15, 2013

I have a Motorola SURFBoard 6580 as my cable modem + router + 802.11n AP. I wanted to add an AP on the second floor of the house for better signal. I have read that APs from different manuafacturers are not necessarily compatible for seamless roaming. Well, I guess the worst case is to turn off wifi on the SURFBoard and get 2 identical APs, but that's not ideal.

Linksys Wireless Router :: Link Light On Motorola Surfboard SB6120 Blinking?

Oct 19, 2011

So I just noticed on my Cable modem the link light is blinking orange, per Motorola if its blinking orange - Computer is connected via a 10 mbps or 100 mbps Ethernet port.
 
On the Linksys E4200 status page it says
 
Internet Port Speed:
Internet          10/100 mbps 
Local Port Speed    Port 1 - 1Gbps
 
Maybe I just noticed this with this router, but I'm pretty sure this didn't start happening until I updated to 1.0.03. 
 
Previously the link light was blue indicating a 1Gbps connection.

Linksys Wireless Router :: E2000 Setup With Motorola Surfboard Cable Modem

Jun 10, 2011

I recently switched from dsl to cable. I have a e2000 router that I would still like to use. The modem I have is a Motorola Surfboard SB6121. It has no options that I can modify. The modem has a built in DHCP server. However, I can't modify it and I don't like the ip configuration it uses. For the time being I have the modem connected to a switch which is working fine. What I would like to know is how to configure the e2000 to use the modems connection. I used PPPoE for DSL and had login information.

Routers / Switches :: Losing Internet Connection And Stuff?

Sep 26, 2011

It is set to dummy mode so it should just pass through to the WRTG54S router which handles the DHCP.2) I have 6 computers sucking the internet off of the router. One is wireless.3) I have been set up for about 6 months this way. 4) I use to drop the DSL connection about twice a day. I would unplug the WRTG54S and plug it back in and everything would reset and work. Then, recently it has gone to about 15 times a dayThen, we have to make a major electrical change in the building, which required us to go to generator power only for 5 days. For 5 days, we never dropped the DSL connection a single time. Power was restored. Generator sent back home. Problem is back. Dropping DSL connection again.5) Hooked up APC battery backup power smoothing device to 3 cpus, WRTG54S, and DSL modem.
