Question about RCA Cable Modem DCM315R (11603540)

2 Answers

Frequency change Our cable system has again moved frequencies around (I work for Comcast). I have about 1000 of the RCA modems that were out in the field six months ago, before we changed the frequencies. Now, we are trying to use these modems again. In some areas we have a 597 mhz and in others 567... there are also a few with a dual downstream (both 567 and 597). The problem I am having is, if there is a dual downstream, the modem will only go as far as 597, thinking that that is the DS it is supposed to lock on. Is there any way to manually tell the modem which frequency to lock on? If not, I am stuck with 1000 useless modems in inventory. The terayon modems have a specific web page where you can actually tell the modem which frequency to lock on... This is what I am looking for, Please Help!!!! I have done the manual resets (with the pen on the back of the modem), and the power cycles (pulling the power plug) to no avail...

I figured out that with the RCA modems, if you pull them off the network ( disconnect the cable) , do a system reset (push the button on the back) for 45 seconds it goes into (what I call night rider mode) with the lights. After it is done with that it will give a class C address to the PC plugged into it. You can plug the gateway address into a browser and get into a configuration mode. There may be a place to reset the freq. not sure though. Sometimes you have to do it a few times to get it into this mode... once you lock in a configuration change I have never been able to get back into it without doing an other reset. Give it a try.

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 have an RCA Modem with an AC power input. 4 pin Can you tell me what voltage the input is and what frequency?

It should be on the power adapter itself after output.
If your in the US it's 120V 60 Hz.
Why are you asking about frequency?

When I recieve a phone call through my comcast phone, it disconnects my wireless on my Belkin

I assume you are using a Comcast modem that you plug your phone into.

Does a wired connection to your router work when you get a phone call or just wireless the wireless is cutting out? If both cut out then this problem is on Comcast's side. You can call them using 1-800-COMCAST to have them fix the issue.

If the wired connection works but wireless does not, I would guess you are using a cordless phone that is running on the same frequency your wireless router is. If this is the case, you can change your router's configurations to operate on a different frequency. This can be done by opening up your internet browser and entering the router's configuration menus by using a URL(address) of 192.168.1.1 (possibly 192.168.0.1). Once you are in the configurations, look for options for wireless frequency and change them to something else.

If this does not work, I would suggest calling Comcast because the problem more than likely resides on their end.

Poor low frequency

Nope, the circuit boards have nothing to do with transmitting frequencies. There are only 4 items on the Technics 1200 that transmit frequencies...

1) Stylus/Needle
2) Cartridge
3) Tonearm
4) RCA Cables/Leads

If you've already replaced 3 and 4, the problem lies with either 1 or 2. Or the RCA cables you replaced were not done properly, or you used poor quality cables. Double check the work.

What it sounds like to me is that your router has been running for a while, and thus start to break down slowly. You coul try power cycling it.

power cycling:
1.) Only unplug the power cord from the modem only, for about one minute.
2.) After one minute has passed, plug the power cord back into the modem, give it a few seconds to boot up again, and it should work.

If the modem still does not work, then the problem might lie with the computer itself, very hard to see happen, but it could still happen.
If in then that case, you would have to system restore your computer to an earlier date. that it was working fine on.

802.11g upgrade

You can have comcast allow you to log in using the new firmware at 192.168.0.1. You will need the user name and password from them. This will alow you into the firmware so you can change settings, including the PCMCIA card.
