Motorola Surfboard SBG6580 / 2nd Computer Keeps Randomly Disconnecting From LAN?
Oct 12, 2012
I have a 2nd computer wired up to my modem, but the LAN keeps randomly dropping every 2-5 hours It never drops for my main computer.I tried swapping cords and ports, but it still disconnects, while my main computer remains connected The internet worked fine when connected to another modem in another house.Do you think this is a problem with the modem or Windows7?I hard-reset the modem to factory settings, but it still happens.the modem is a Motorola Surfboard SBG6580

I have time warner internet service and just upgraded my service to their extreme internet. In doing so I had to change my modem to a docis 3.0 modem; the motorola sbg6580. Its a modem that has a router and wifi built in but its really bad and not nearly as good as my net-gear router.

Since the new cable company won't let me use my SB6141, I need to pick up a new cable modem. One that works with Oceanic TWC is the new SBG6580. It has wireless built-in; however, I don't want to use it. Is it possible to use this modem and leave the wireless off? Or does the wireless automatically turn-on whenever the modem is on? With all that said, is the built-in wireless any good? I recently purchased an ASUS RT-56 and would prefer using it to some built-in system.

Looking to add my belkin wireless router to Sbg6580 router as an access point to extend wireless. I've read up enough to understand the fundamentals - LAN to LAN, changing IPs, turn off DCHP etc. - but am confused by a couple of things.
First, belkin faqs says to Open the router page, click on "use as access point" (I get that) "Select Enable" (I also get that), and then it goes on to say "This will give you the options to set the IP Address and Subnet mask for the router.**These settings should match your existing network settings; by default the IP address will be set to 192.168.2.254 and the Subnet mask will be 255.255.255.0". Does this mean to set the IP address of the Belkin to that of the Motorola (which is 192.168.0.1) on this page?
Then the FAQ goes on to say access the LAN and "change the IP Address to something such as 192.168.2.47 or you can use 192.168.2.200.**As long as the first three sets of numbers match your existing network, you will be fine". I thought the LAN IP address should fall outside the DCHP range of the Motorola? So if the DHCP range for the Motorola is 192.168.0.2 through 192.168.0.250 then I'd assign 192.168.0.251 to the Belkin?

I switched to comcast internet recently and got a new modem. The modem is the telephony Arris one, but the problem is that I already have a Motorola SBG6580 but can not use that for my wireless laptop options. I want to be able to use the SBG6580 as my access point and LAN, but it isn't allowed any internet to share wirelessly?

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.

I own a Motorola SurfBoard SBG900 wireless modem. It has worked fine for years. I just went on vacation for 2 weeks and unplugged my computers, printer, modem etc. Upon returning I can not get any wireless signal from my sbg900. The wireless light at the bottom is no longer lit up either. I can connect via ethernet cable however.

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.

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).

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.

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.

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.

Would this work ?. also, on the back of the modem is a rectangular, not the typical, usb slot. I cannot move the modem because it is connected to the wall. I don't want to use an extra long wire either. What do I need to buy so I can use the wired modem, as a wireless one on my pc downstairs ?

I can't connect my router (WRT54GL) to my new cable modem (Motorola Surfboard SB6120).
Some info:
1) Cable modem works perfectly when connected directly to computer ethernet port
2) ISP is Optimum Online
3) Using Automatic DHCP setting on router
4) Using MAC cloning on router
5) I can access the router's admin screen from the PC
6) I can connect to the router wirelessly, but no internet access
7) I've tried powering down everything multiple times, still no internet access
8) I upgraded the router firmware to 4.30.14
9) The "link" light on the cable modem never lights up when connected to the router

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!

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.

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.

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.

I get this at random times. My internet disconnects until I reset my modem and I don't think it has anything to do with the modem because I had it replaced by my ISP and they did a few line tests and nothing was wrong. What can I do to avoid having this problem anymore? It's been doing it for almost 2 weeks now and when it decides to do it is random.

It's plugged in via an Ethernet Cable from a Homeplug Adapter, since the modem is not in the same room as me. Basically, I've been having problems with the internet randomly disconnecting and for no reasons. There's some days where it'll go fine, no problems at all, other than a few things that always disconnects it, then there is days like today, where it keeps connecting every time I try to go to a webpage. I cannot seem to upload anything to the web (Youtube, Mediafire, etc.) without the internet disconnecting before it uploads. The only other problem that I've had constantly, even if it is working fine, is I cannot seem to do a video call on Skype or really use my webcam to broadcast online without my internet disconnecting. Also, when I play games via Steam such as TF2, Call Of Duty, etc., I have no problem with the internet at all, it works smoothly and never crashes when I play games. And the desktop is the only thing that ever has this problem. We have 1 other desktop, and 3 laptops (all connected wirelessly) and they do not disconnect from the internet at all. This has been going on for quite a while, and I'm still not certain on what is triggering it.

My internet will disconnect and reconnect randomly, nothing works every time to fix it, the time online and offline is random, sometimes it works when i turn on the computer, sometimes it doesn't , sometimes it stops after a while, sometimes restarting works.
I am running Windows XP on a desktop computer with the most current service pack installed and I have a linksys wireless router installed in the computer. I know the router isn't linksys, I think it may be netgear. I have no way of connecting wired to the router. My bf's laptop running windows 7 is used wirelessly in the same room as my desktop and rarely has any problems connecting. I should mention that this problem also occurred on this computer while living in other locations and using different routers, but it was never this sporadic. It was best when used in conjunction with the linksys WRT54G router.
I realized today looking at the status of the wireless network connection that the network name and signal strength will disappear and reappear randomly, all while still saying I am connected and that I have sent and received packets, and sometimes randomly changing connection speed as well. Sometimes an alert bubble will pop up saying that my internet connection is connected and that I have excellent signal strength, with varying speeds, but the internet still doesn't work. Or sometimes it does work. How to access it.

When I click on certain links, the webpage doesn't load, and I can't access that page only until going to it later.
Sometimes it says "no data received" and sometimes it gives the usual page for no internet connection
