I have a Motorola modem SURFBoard SB4200, along with a wireless Linksys router that connects to that modem. The router works normally but the modem often dies and restarts itself after about 1-2 minutes.
What could be causing this problem? How should I start debugging it?
Could an excessive amount of network traffic be bringing down the modem? Are there any tools that can monitor the modem?
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.

It won't respond. This isn't just for a moment. I'll unplug the modem and plug it back in. I can access the modem after that with my browser, but more often than not, I don't regain connectivity. It keeps trying and failiing.its a Motorola SB5100 from 10 years ago. how to seperate bad wiring from a bad modem?

My ping will stick to around 40-50 in a server, but continually spike to 80-100. I don't notice it all that much, but on others' screens I'm choppy and look laggy.I'm connected to a router, but it seems to happen while directly connected as well. It has nothing to do with others on the network either. The modem is old, not sure if that has anything to do with it, a Motorola SB4200.

The modem itself has a built-in WIFI (G) and one ethernet port, but not good enough for my purposes. I need more wired connections and an (N) WIFI connection, which the D-Link could provide, if I could get it to work. I just cannot get the two pieces of equipment to talk to each other. I can set up 2 independent LAN's, but no WAN (internet connection) from either. D-Link has provided pages of instrutions, but nothing works.
View 1 Replies View RelatedI was working with Motorola SB6120 cable modem regarding an odd power cycle issue (it would power cycle randomly for 24 hours). While trying to diag the issue, I was taking a peak in his router config and found a port set to forward as:
Application: Comcast
Port From: 888
Protocol: Both
IP: 192.168.100.1
Port To: 80
I understand that his modem admin page is now available from the internet. He said his friend set this up to "modem", but I don't see any advantage of having this done. At this point what are the other advantages of forwarding such ports?Another key note: When the port forwarding was disabled, suddenly the power cycle issues stopped.
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 ?

View 13 Replies View RelatedI have a 192.168.1.xxx network connected to Verizon FIOS via Actiontec MOCA / router. I also have a 192.168.15.xxx network connected to Comcast via Motorola VT2442 router (used for Vonage) and a Motorola SB6121 cable modem.
Each network has it's own gigabit switch connected to each router. The two networks are physically separated but switches and routers are physically side by side.
What is the best configuration to allow devices on 192.168.1.xxx network to communicate with devices on the 192.168.15.xxx network (share printers, NAS, etc), but still have each network served by it's respective ISP, and each device still get it's dhcp, dns, gateway, etc from each respective router?
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.
View 3 Replies View RelatedI 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.
View 2 Replies View Relatedwhen I connect my DIR-655 to the Motorola SB6141 cable modem I notice that the link speed LED on the cable modem never glows blue indicating a gigabit connection, it only glows amber indicating a lower negotiated speed. I am using a Cat6 cable between the two devices and have also tried a Cat5e cable.
When I try and force the WAN port speed to 1000Mpbs in the router interface the cable modem link speed will not light at all with no connectivity. Only resetting to Auto WAN port speed restores functionality albeit at the lower negotiated speed setting.
I'm running the DIR-655 rev B1 at 2.03NA firmware level.
I did connect the modem directly to my PC that uses an Intel Gigabit ethernet card and still had the lower connection indication (Amber) so it seems that the modem might be faulty.
I'm having trouble with my Linksys X2000 modem/router to stay connected to internet. I have tried upgrading the firmware & changing my ip address, but still with no success.The router part is staying connected, but the dsl will drop off. I have to unplug to get it up and working again.
View 9 Replies View RelatedHaving the issue for over a year now, I'm wondering why there isn't a fix for the mentioned connection drops of the WAG200G? I'm on the newest firmware now (1.01.08(3)) but still every so many minutes: bam, lost connection.
View 9 Replies View Relatedsome reference material about configuring my WAG320N to use my cable modem via Ethernet port 1. I've seen it mentioned that's its possible, however I've been unable to sort it out myself.
And before you ask, I've brought the DSL router as I'm moving in the next 12 months and my new base will not have access to cable internet and I'll be reverting back to DSL.
my WAG160Nv2 drops the connection each day at the same hour (4:20pm to 4:40pm aprox.)I think that is because my ISP don't give me a static IP address and the connection must dropped once a day. in my old router I could put the time for the drop. I don't find something similar in the WAG160Nv2.

[code]....
I have a WAG160N v2 and a UK Online broadbad account, windows xp. The connection intermittmently drops out, approx 15-30 times per day. I have spoken to my ISP and had the line checked (no packet loss issue), checked the settings on the router against my ISP and also updated the router firmware all with no improvement.
View 2 Replies View RelatedFrom time to time, when I wake up an specific station from sleep mode, the router loses its connection with Internet. It still has the line synced, but there is no Internet connection.I still can access the router through browser though. If I hit "connect" to establish a manual connection, it does not work. I have to switch the router off and on and wait for the whole process of syncing and connection, then I have Internet again.
I thought this could be something on that PC (old XP) sending some weird packet to router when I wake it up, but I tried with a newer PC (Win 7 64 bits) and the same problem persists. Also, this only happens when I wake up the PC. If it is off and I turn on, or if I restart, the problem does not happen.
The router (WAG120N) has an old firmware version (V1.00.12) because the latest available is buggy and had some problem with my ISP (limiting the bandwidth). However, I have this firmware for like 6 months and the problem only started 2 months ago.
This is a bit of a pain as the behaiviour is not consistent. whenever I connect to the Device webpage a number of things may happen
1. There is no connection - the page tries to load but never does. While this happens the router drops the ADSL connection and re-connects. I have to close the browser session and try again later. OR
2. The Browser session connects but at some point after the connection, say when I am trying to save changes or even just browsing through the config pages the session hangs, and again the router drops the ADSL connection and re-connects. I have to close the session and try again later.
I have noticed this happens when I use my OpenSuse 11.4 Linux Box using Firefox 5 or even using my Win 7 Box using IE9.
My internet connection drops every 10-30 minutes and reconnects. The modem seems to reset (every light except the power one). I have a Zoom model 5241 modem. Additionally, I cannot access my modem's status page [URL]. It's as if I'm trying to access a site that doesn't exist. Comcast sent a tech who replaced a splitter, but that didn't work.
View 1 Replies View RelatedImmediately after a power outage, my internet connection predictably drops after a set period of time or usage. It is either after about 30 min or 5-15 mins of watching Netflix. I have a modem hooked up to a wireless router and use the network on my iPhone, laptop and Roku. Since the problem, I have dropped to just having my laptop connected but this has not worked. The wireless network will disappear after the 5 - 20 mins, the light on the modem and router will show no internet (all other lights are normal). Internet connection will be reestablished if I either unplug both the modem and the router (not just one or the other) OR if I unplug the ethernet line from the modem to the router and plug it directly into my laptop (the internet light on the modem will go from "off" to "on"). Despite internet connection working from transferring from the router to the laptop if I connect it back to the router, the internet lights goes off again (resolves upon unplugging and plugging modem and router back in). The internet has not yet dropped when it is physically plugged into my laptop.
I have tried the following:
-Powercycling (temp fix until it crashes again)
-Plugging into a different outlet (I cannot connect it to a different phone line, only have 1 with DSL. Also, I do not have phone service or cable, just internet via DSL)
-Resetting modem
-Resetting 2 different routers
-Calling ISP, their test of the modem was inconclusive
Again, my wifi does not see my network whenever the internet is dropped or the ethernet cord is unplugged from the modem. The outlets I have it plugged into has some type of electrical issue, two electrical devices have shorted out in the room they are in. I do not think this issue is electrical, everything seems to have constant power (unless the power outage shorted out something in the modem). Below are some details of my modem and router. I will provide any additional info requested. I will gladly buy a new modem but I want to see if it can be fixed first.

It's a Windows 7 Pro 64bit machine with a (newly installed) Asus P8H67 pro motherboard and an Edimax ew-7612pln pci-e card, the router is a thompson 585v8 router with the latest firmware on (upgraded as part of troubleshooting). I upgraded the wireless card drivers one time whilst it was disconnected, it appeared to work for a few hours but then dropped again it also went through a phase of connecting to the router as an 'unidentified network' with no internet access although I don't believe it was attaining an IP address. When it was connected the internet was pretty slow and anything like a file down load would knock it off completely. There were no errors at the time of disconnection in the event log (bar a DNS error or two saying it could not locate the website I was trying to get to before it failed), however the only information type events I noted were a few services stopping and starting and an odd one regarding the host not being able to find the 'master browser' which was identified as another laptop on the wireless network.
The machines are not in the same work group or in a domain, all other laptops and devices on the network work fine and are very stable - as was this one up until a couple of weeks ago. I've uninstalled a couple of pieces of software that were recently installed ; VMware player (which added virtual NICs upon installation and funnily enough made the wireless reconnect after a few hours of downtime upon installation...but the effect was shortlived) and some asus mobo utilities.

View 2 Replies View RelatedI am relatively good at installing and troubleshooting smaller sized networks... I am having trouble with one of my customer's networks and I think I have the problem narrowed down. r issues.I have a customer with a FS726T switch and ~20 computers connected to this switch running DHCP assigned addresses.The switch is assigning addresses in the 10.0.0.xx rangehe customer currently has an old T1 line coming into a Cisco router, which then directs traffic to port 20 on the switch.The problem is, we are replacing the old T1 line with a newer 50mbps cable connection.The cable company pre-configured their router with a static IP address the 68.116.xx.xx range. The Subnet is also different than the Netgear's subnet. I would like to keep the old T1 connection in place. I believe they have data that needs to go to their mainframe/backbone server at corporate.
I cannot log in to the cable modem. IT is an SMC SMCD3G with a staic IP. I tried changing my PC's IP address to the same gateway but cannot get into the cable company's modem, even using a static IP with the same gateway as the modem's gateway address. I don't want to reset the modem/router and lose the cable company's settings.I am pretty sure for the devices to communicate, the following has to be true?:1) Cable modem and FS726T must be on the same 10.0.0.xx IP range?2) Cable modem and FS726T must be on the same 255.255.255.0 subnet mask?
