I just recently had an RCA dcm425 modem installed today. I, stupidly, did not check the Internet connection before the installation guy left. Now, the cable activity light is flashing and the cable link...

it is common for the network port to fail on the DCM425s. a couple of things to try...1. a new network cabe2. hold the reset for 30 seconds (small hole on the back)3. try using the usb connection (this will not allow for a router connection and XP should give you a genaric driver so that you can see if the modem is working other than the network port)
if all else fails, it would probably be easier to take the modem into the local office and ask for an exchange. trust me, i am a service tech for a cable company and it is a lot easier to take the modem in for an exchange than arguing with some one on the phone who has no clue how to trouble shoot a modem and then waiting for another incompetent tech (if he didn't check to verify that it was working he was incompetent) back out to screw it up again. also ask if they have any motorola modems... there more reliable.

My motorola SB5101 cable modem is connected properly. The power light is green but the receive light is keep on blinking other lights was turn off (send, etc.). Does my modem has a problem?

This light pattern indacates that the modem can not establish a connection to your internet service provider (ISP). This is typically do to a signal related issue. To trouble shoot the problem you will need to connect the modem directly to the main cable line where it first enters into the home. You will know when the modem establishes a connection by the top 4 lights becoming solid green. If at any point all 4 top green lights start to blink in sequence than you will need to contact your internet service provider to "unwall the modem". Remember most internet service providers require you to register new modems on there network. So if you have not all ready completed that process you will most likely not have access. If you can not get a connection from the main line than there is a issue with either the modem or the signal coming into the home and you will need to contact your internet service provider.

I hope that information above has helped is some way.
If possible please rate this solution.

My modem keeps dropping connection. I have called my ISP and they say everything is running just fine. It happens when i am playing counter strike source and i start lagging badly and all of the sudden my...

Intermittent connection issues are very difficult for internet service providers to trouble shoot. The first step in trouble shooing any Intermittent connection problem is to look at the chain of equipment involved in flow of data from the internet service provider to the end user. In most homes the packets enter from the main line to the modem, than from the modem to the router, and finally from the router to you computer. So that means that the issue can be caused from the following equipment: main cable line, splitter, modem, router, or the Ethernet / wireless card of the PC. The first step in trouble shooting this problem is to wait for the internet to drop off. As soon at this happens go to your modem. If the top 4 lights are not solid green then the the modem is losing it's connection to the internet. This can be cause by some thing as simple as a bad splitter in the home or some thing as complicated at an issue at the pole. If the modem drops the connection I would recommend contacting the internet service provider and demand a service call to swap the modem and check the pole. Now if when the connection drops the modem still has access than the issue is most likely with the router or PC. If more than one computer loses it's internet access than you can rule out the computer as the issue. At this point I would have to recommend bypassing your router for about 48 hours. If the issue does not return than you know the router was the source of the problem.

I hope that information above has helped is some way.

Ethernet light blinks no Internet

Serveral soultions to try and they are at no cost to you. First, try re-booting the modem. Your modem stores cache just like a computer does, and it can build up on you. I myself unplug mine about once a week.. Two, in the control panel under Internet Opetion under browser history click on delete and confirm the delete, this will delete your temp. files. You might have exceeded the amount of cache allowed by windows. Finally make certain that you have ipx, and spx protocol installed on your comuter. If this doesn't help, I would get a new modem from your isp, more than likely it is bad. I know verizon modem are good for maximum of 2 years and average 1 year. I would recommend westell 6100 G moem and get a wireless router to go with.

Modem only shows two lights; can't connect my PC to the internet!

It sounds like you've lost connect to your ISP. Have you checked with them to make sure you don't have an interruption of service?
If it's not an IOS, work with the ISP support technician to trouble shoot. They may have to replace the modem if they can't isolate the problem.
