When I type in it asks for a login

> where do I get that from

You ask your cable-modem company, if you acquired the cable-modem from them.

Or, if you purchased the cable-modem, then the ID/password were included in the packaging.

I don't have cable but in order have the wireless

Yes you certainly need a cable connection before you can use the wireless capabilities of the cable modem.
Without a cable connection the modem is useless.

RCA DCW615R WIRELESS Cable Gateway , Factroy Installed Firmware needed.

I had the same issue with my RCA DCW615R. First time my ISP Comcast flashed it back to the old version. This time I could not find anyone who new how to do that. I used to have the software and I have searched the net. Seems they provider RCA does not have it.

This time I called Comcast because I noticed that the brought me to their software update. They supplied me with the user name and password. I was able to get into the firmware and change all the settings using the new firmware. I think the only reason they gave it to me is because my printer is a network printer and it would not work unless I could access the firmware.

The old does not work anymore because that was Cable Modem mode or CM mode. The new address does work but you will need the user name and password from your ISP, this is RG mode or residential gateway mode.

Liked the old firmware better but they both do the same thing. Seems the Gateway works better with the new update. Still I would like to find the old firmware not sure why RCA doesn’t have it.

The Rca DCW615R

You didn't say who your cable internet provider is, and many (or most, including Comcast) such providers require that the cable modem's MAC address be registered with their network. It's a security feature to prevent unauthorized (read: unpaid) users to access their network. The MAC address is usually found on a sticker at the bottom or rear of your modem. Write it down, then call your cable company's tech support the register it. It should work just fine after that.

RCA DCW615R Wireless/Cable Modem has problems loading some websites.

your could try power cycling it, thats what works for me, i think it has been running for too long, thats why her internet connection loads up pages slower than before, and as for the weather websites, i am confused by that as well. but, here is how you power cycle:

1.) unplug your modem.
2.) wait about 1 minute.
3.) plug everything back in and wait about 1 minute.
4.) test out any website, and if still doesnt work, check all of the wires pluged into it, and unscrew the cable wire, and rescrew it back in slowly.
5.) and when all of this still doesn't work, then contact your internet service provider, because chances are, its something wrong with that modem, or your internet service provider.

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.

How do i set up a wpa or wep on my modem

1.) Well first, you must open your web browser up.
2.) Then you would type in the address bar: (being the default ip address for this modem)
3.) If you haven't changed it already, the username is <blank>, and the password is, "admin".
4.) Once logged on, you would go to the far top right, where it says: "Wireless".
5.) Then, on the column on the left hand side (about mid-page) you can see five different tabs, click on the one thats says: "Privacy".
6.) Now, this is where you have to decide what kind of Security you would want(either a 64-bit or a 128-bit encryption key) NOTE: having 128-bit encryption key will be a long password.
7.) Then, in the WEP Passphrase, you would type in something that you would remember, it could be anything, just as long as you can remember it.
8.) Then click the "Generate WEP Keys" button right next to it.
9.) Now, on the Default Key right under it, it gives you choice of 1-4. This means which channel would you like to connect though. So here is an example, if you picked a128-bit encryption kep with a default key of 3, then you would look at the corresponding chart at the bottom of the page. And at the row that says "Key 3" in the "128-Bit" box, then that would be your password for other devices to connect to this modem.
10.) And when you have saved you password somewhere, click "Apply", and you done!
