Question about Arris SB5100 SURFboard DOCSIS 2.0 Cable Modem (50120900100)

Modem disconnects on a daily basis

Every day, around 3-3:30 P.M. to about 4 P.M., my modem disconnects and drops the signal. Repeated power-cycling does not work, what could be the problem? I've had many altercations in the past with my ISP (Comcast) about this issue before and it was resolved for some time, until recently. In the past, I had a faulty modem, and my cabling was bad.

Type in 192.168.100.1 into your web browser, that should bring you into the modem, check on what your dB levels are.. Cut and paste your output in case this happens again. Your modem will have a log of the disconnects that you can use when talking to Comcast. It sounds like you might have a pwr problem with your dvr. Are they plugged into the same outlet? Are you able to contact Comcast while it is happening? As a workaround, try plugging each into a different outlet. I would open up a trouble ticket with Comcast and have them escalate the problem. If it is a comcast modem, they can bring you another one out.

Its likely that the node you are connected to is simply overloaded. And a million people are getting online at that time, and Comcast just cant support everyone... For this there is no fix, Unless you switch to another ISP

Hi, I’m facing one issue with D-Link (DCM-202) Modem from last week. The internet connection frequently disconnecting with interval time less than 10 min. I have checked with service provider COM CAST...


Is this a new issue or a recent harware/cable change or did this use to work and now has the disconnect issues.

Ensure that your cable has NO Splitters (especialy outside) from the Drop outside to your modem.

Check all cableing between Computer and Modem to Cable Drop.

You can also look at the Modem Status Page to check your UpStream and DownStream signals. You may have to have someone come out to check out the line running from your house to the pole (or pedestal if its underground)? Many factors can cause an outside cable to deteriorate, and when that happens you can end up with alot of signal leakage and frequent disconnects. And that goes for both overhead and underground lines. Good Luck, and post back if you need more help. (try to include your Modem Status Logs)

Comcast is my service provider and I have had an RCA DCM 245R modem for almost 10 years. Until recently it has worked fine. On an ever increasing basis I am losing internet connection and when I look at...


Hi,

It can be an issue with the modem or with the line. When the line drops the link then the modem shows only two lights. And, when you power cycle the modem (unplug and replug it) it establish the session again with the comcast.

So, i'll suggest you to get the line checked first and if comcast finds that line is working fine then get the modem replaced.

I am having problems getting conected to the internet on a daily basis.When it happens the orange light on the router is flashing. Checked all connections each time & all seem ok. Please advise.


I would contact your internet service provider. There is likely something wrong with your line that is causing your router to loose signal. I don't know what type of router you have, but a loss of signal usually causes that. There are other reasons, such as, your modem is going bad, your cable from the modem to the router has an internal break in a wire, your router could be going bad as well. Try power cycling both your model and router. You can do this by unplugging them for a couple of minutes and them plugging them back in. Plug in the modem first and wait a few minutes, then plug in your router and wait a few minutes, then try getting on-line. If this is a persistent issue even after doing all of this and contacting your ISP, then I would conclude that your hardware (modem, router, &\or ethernet cables) is giving out on you.

You may have a bad power supply.
You would be better off picking up a small APC or UPS and have all your computer devices running thru.
It is common that after a power interruption the modem must reset to regain it lost signal

Modem drops connection. Must disconnect and reconnect to restore


There are plenty of aftermarket Cable Modems for sale at most major retailers (Best Buy, Target, Walmart, etc..)

I would go and buy a decent one of these and try it out to really test to see if the modem is indeed the issue here. If the new one works and doesn't drop the connection anymore then problem solved. If however the new one does do the same thing I would check for proper venting area (make sure you don't have anything on top of or burying your modem) first. If that's fine then it could possibly be issues with your actual line and in that case you'll need to harass the cable company until they actually send someone to test your lines.

Modem crashes, and won't work again until I power cycle


you may want your cable company to come out and check the forward signal to the modem wich could be to low , or the return to the modem  could be to low/high . one last thing is ,it could be having packet loss so severe that it drops your connection even though the modem stays linked up.

Dropping internet connection


check if this problem is with both wired and wireless computers, if not with the wired..only wireless has problems, check if you have any other wireless device operating in the same frequency of the router..if s, turn off other devices and check b.cos that me interfere your w/ls connection, if wired is having the same problem, connect modem straight to the pc and observe the connection, so that you can isolate problem..
