Purchased this modem for my grandmother's PC. She's 98 years old, and only uses her computer for Juno Email (Yes they're still around!!!!) and playing Solitaire.

I had the hardest time finding a dialup modem in my local computer shop. Kids today don't know that back in the olden times we used to use analog telephones to DIAL UP to other computers in the world! CompuServe, Prodigy, even the good ol' BBS's of yesteryear..... All accessed by plain old telephone lines! spent 5 minutes talking to the kid at my local store and trying to explain that I didn't want a cable modem, and I didn't want a DSL modem. I wanted a dialup modem. He looked confused. When I tried to explain that you plug it into the phone line he said "Yeah, that's DSL"... *facepalm* no kid. it's not.

Anyway, This modem did just the trick. Plugged it into the USB port on the somewhat new PC running Windows 7 Po 64 bit Windows recognized it right away, and I didn't even need to install drivers. Tested it over my VoIP line, and was able to dial into the local Juno modem pool no problem.

I got a laugh at the Q&A's her eon amazon about "can you dial into the internet with it" and people saying "No".... Must be the same kid at the store I tried to sell me a DSL modem.

By all means you can use this to dial into an local Internet Provider, as long as they have access to a dialin pool. It's not DSL, not Broadband. But if you're a 98 year old grandmother who wants to get emails from her grandkids, it'll do just what you need!

This is a hardware modem, and I think because of this no sounds come out of the computer speakers to hear the dialing or fax handshake tones. However, it has Off Hook and Data Transfer LEDs that come in handy for troubleshooting. I am using it with Windows 8.1. As I found out after wasting the major part of a day trying to get another modem and this modem to work with Windows Scan and Fax, there is a problem with Windows Scan and Fax on Windows 8.1, and maybe 8. It does work in Windows 7 and below. The great thing about this modem is that it comes with BVRP Classic Phone Tools and it does work with this software. I gave it four stars because there is no way to make the sound come out of the computer speakers, and I tried for a long time.

If you have Windows 8 or 8.1, I recommend this modem because it comes with software that works on Windows 8.1.

The drivers that come on the included CD will not load in Windows 8.1. They are for Windows 7 and an error message is returned. However, Windows 8.1 found the modem and installed drivers for it as soon as I plugged it into a USB 2.0 port. If you plug it into a USB 3.0 port, it may not work. It didn't on mine. However, after plugging it into a USB 2.0 port the drivers loaded properly and it worked. I then plugged it back into the USB 3.0 port and it keeps working.

Having acquired an ASUS 1215B netbook running Windows 7 64 bit and only a wifi for internet connection I needed a USB modem. Trust me many out there are not ready for the 64 bit and had to be returned. So, after reading the reviews on this one I sent an email to Rosewill tech, and in a short time had the response that all that was required was to plug it in to my USB port. No need to even use the disk at all. In less than 60 seconds I was connected with zero drama. Excellent product,fast tech support,fast shipping. Regards

I needed a modem to connect to keep a DoorKing door entry system updated. Modem installed easily (64bit Win 7 Ultimate.) After I connected I could download data but could not upload.

Kudos to Rosewill support for rapidly sending me another RNX-56USB after a brief conversation. Same problem. Apparently the entry system's modem/software requires full hardware handshaking. I dug up an old Hayes Accura modem - success!

Returned Amazon's modem a bit wiser and appreciative of both Amazon and Rosewill's excellent support.

Yeah the very nice software that's included might work on Windows8 OK, however, the modem doesn't work on ATT's U-verse Digital Phone System... I have a box called "None Working Stuff" and this is where this modem is going. I'm not going to return this item because it's not their fault that this modem won't work on my phone system and it only cost 25 bucks. Also, the manual & DVD was Printed/burned for 98SE, ME, 2000, XP & Vista operating systems. It says that you can contact the company at [...] if you want -- I haven't tried doing it. Good luck.

This device is a real modem, and "just works" with Linux. No special softmodem driver or other nonsense is required. Recent Linux kernel versions detect it as a USB CDC ACM device, and present a generic serial interface you can use with a terminal application, getty, hylafax, or a PPP dialer. Gnome PPP and wvdial detect and configure this modem automatically. It is suitable for applications where you might otherwise need to hook up a USB to serial adapter and then an external modem, and available for a fraction of the cost and size.

I have deducted one star because in my limited testing, I was unable to successfully get Caller ID working. The AT commands are present, but the modem never returns a name or number.
