Summary: I upgraded computers from an older model that had a built-in fax modem. I still have occasion to send faxes the old fashion way to a client. This USB dongle was recognized by Windows 7 as a fax modem when I plugged it in and worked right out of the box with no fancy installation or anything.
Summary: Shipping was on time. Unit worked out of the box as expected. Software leaves something to be desired but with Windows 8 I don't use it anyway. The fax package in Windows 8 hooked up with it immediately. Took me 10 minutes to set the whole thing up and send the first fax.
Summary: Although the "Classic Phone Tools" application included with this modem works fine, this modem does not work with the built in Windows 7 "Fax and Scan" program. The program finds the modem but never send a fax out - it just hangs forever. TRENDnet tech support was not helpful.
Summary: For those of us out there stuck in the 90s sending/receiving faxes to/from our clients, I needed this for my new computer with no 56k modem. This did the job and worked well. I didn't even need the included software to set this up with my Windows 8.1 machine.
Summary: Windows 8.1 wasn't listed as a supported operating system, but I took a chance and ordered it. Plugged it in, Windows found and installed it. Then I added a phone cord. Used Windows Fax and Scan to send my first fax. Worked like a charm.
Summary: This is the second Trendnet modem I have purchased. The first one lasted me several years. That was acceptable. The second one barely made it 6 months. This is not. It got normal use on home dial up internet. Today I'm buying a new one and it won't be this model, piece of crap!!!
Summary: Got this for a windows 7 PC because I didn't feel like installing a PCI modem and this was a very inexpensive alternative. I used this to setup fax sending and receiving using Windows 7 fax program. Works perfect with no problems. Installed very easily with no effort at all. Setup was about 10 mins.
Summary: I am trying to use the unit for faxes, not dial-up to ISP. Unit reports "no dial tone". I checked the line and there is a dial tone. I tested this on two units, same error. I switched to US Robotics 5637 (@ twice the price) and that works fine.
