Picked one of these up off of E-Bay for $0.99 plus $12.00 Shipping, Sweet!

When it arrived it was NIB with the USB and Ethernet Cables still in Sealed Plastic!
I Shutdown my Old RCA Cable Only Modem and plugged this Sweetie in. Booted up called Adelphia and had the Mac ID Changed, another rebooting of the modem and she was up and functional.
Surfed on the Primary XP Pc, then tried the MAC and then went in and setup the Wireless, booted up the PSP and we were connected! Tried the Laptop with VISTA and she worked great!

Anyone know where I can get the firmware to update tis to WAP ?

Also it came with a RCA 802.11b PMCIA, but I'd like to use a 802.11G ,but just plugging in the card doesn't work...
So must need some sort of driver on the modem to add support for other cards.
Anyone ave ideas how to access the box O/S to do that?
I imagine it some sort of LINUX base most everything is nowadays.

The pros of these modems is they are cheap, got mine for $20.00.

Cons are that the modem lacks some common sense end user controls. Such as you can't turn off wireless connectivity totally. You can only change the last digit of modem's router IP address.

The modem is also try to be a bit too accomidating to your ISP. When you first connect the modem is in RG mode (residental gateway) and works as modem and a router. When the modem first connects to your ISP, it will asked your ISP what mode to be in, and the ISP can turn off the router fuction and put it into CM (cable modem) mode.

In CM mode it doesn't work well connected to another router (for example if you have a router with more advanced wireless features, VPN, or a better firewall).

I was just about to take this modem back for a refund when I figured out a back door to get it back into RG mode.

1) Get the modem talking with your ISP, once you can connect and surf fine with a direct connection on one PC....
2) Hit the factory reset button. This will put the modem back into RG mode, but your ISP will still talk to it because the MAC and serial# match.
3) Should work with your router, just remember that the modem only works on IP addresses in teh range 192.168.0.1 to 255 , so if your router has been set to some other IP like 192.168.1.1 you'll need to change it.

Don't forget to set up a password on the wireless, as it default to an open net, and the router needs a new password also.

What if I can't use that default password? It does not work. I can surf the net with a ethernet cable but no wireless so far.

Thanks for any help.

Like Dazzler69, I am unable to log in to my RCA DCW615R cable modem; the username field empty and the password field "admin" do not work.

How do I reset this to factory defaults? The manual does not indicate this.

Note that RCA has redone their site, removing all reference to this product; the above links just go to their home page or are broken.

I found the manual at simplehelp.net, the product page is http://www.simplehelp.net/2006/07/01/cable-modem-troubleshooting-rca-dcw615r/ and the manual is http://www.simplehelp.net/images/cable_modems/manuals/rca_dcw615r.pdf

Thanks for any help!

Dazzler 69 did you ever find an answer to this problem? I'm having the same issues.

Dazzler,

On the back of your 615 there is a small reset button next to the switch and power plug. Remove the power plug for about one minute. Take the end of a paper clip and hold the reset in for about 10 seconds while you plug the power in. Be careful not to hold the reset too long or you can create other issues. This should reset your unit back to default settings.
