Summary: If you're looking for a cheap, but high quality usb adapter to turn your machine into a wireless system then this is the device to do it!
Pros: Windows 7 Ultimate 64-bit system automatically installed the drivers and was up and running in < 5 minutes. The cord is long enough to put the device just about anywhere to achieve better wireless reception, if needed.
Summary: In linux mint and ubuntu, "locate 8712u.ko" will unearth possible drivers for this device, which means the device can be tested before Rosewill download and compile. Once the file "8712u.ko" or "r8712u.ko" is found, then add at the end of the file "/etc/rc.local" (as super user, sudo gedit /etc/rc.local) an appropriate line:
Pros: Connection solid, better speed than 802.11g. Software connect can be automatic. Antenna away from box and power gave better receive/transmit. Zero issues exist for MS Windows installs [Linux is a different story, see below]. The best feature is the cable from a usb 2.0 port to a table top, where the antenna is located, giving a chance for improved reception in a 3-floor building.
Cons: Linux mint and ubuntu require download of driver source from the manufacturer and a local gcc compile and install. The Rosewill documents suggest the wrong steps for Linux Mint 10+ and Ubuntu 10.10+ (50% correct). The provided CD contains outdated drivers and false information [discard it and use the Rosewill internet site]. To repeat: using the enclosed CD will waste your time and result in no progress to install a linux driver. Trying ndiswrapper has no result: this...
Summary: This thing, coupled with Newegg.com's unbeatable customer service is a great deal.
Pros: I've owned this wifi adapter for almost a year.
Cons: ...well, this thins just died one day. 10 months after purchase, but it still died. I expected at least 2 years out of it. I was about to just throw it away when i decided to fill out a RMA form from newegg to see if they would replace it (even thought it was alomost 11 months old) and sure enough, they sent me an RMA for it!! The item, in its orignal packaging, inside a small box with some packing material ONLY weighs 12.5 oz, so i can send it back to newegg for arou...
Summary: While working fine with Windows 7 (just plug and play), Windows XP does not recognize the adapter and you need to have CD with drivers. This is a pretty inefficient concerning that you will most likely want to use your Wi-Fi adapter to download drivers from the net.
Pros: Has a really good reception. When I plugged it in I got a reading from 20 more Wi-Fi networks around me.
Cons: Doesn't support packet injection. If you don't know what this means then this really should not be a con for you.
Summary: OK I have to tell my story, since good experiences with customer service seem to get reported way less frequently than bad ones. Maybe I should have known it was defective and not a driver issue by the aforementioned behavior, but I think I had reloaded Windows inbetween (new build) so I wasn't sure. I tried every driver I could find, but Windows (7 64-bit) refused to recognize it again.
Pros: SUPER-STRONG antenna, wifi N, best form factor for long-range signals, Rosewill customer service ++
Cons: really none, except for the fact that there's always a certain percentage of duds that make it to market...first one blinked out after an hour.
Summary: They engineered this right, with the antenna plugging directly into the base which includes the RF circuitry and demodulator. So the only thing you are connecting to your PC is a USB cable which carries only DC power and digital signals. All the RF cable losses are eliminated, and you can add a longer USB cable without impairing performance. This is much better than the antennas with short coaxial cables that people are always complaining about.
Pros: The 64-bit drivers for Win7 download and install as soon as you plug it in, though you will need a network connection to get them. They are the latest drivers too (1086.27), dated 7/8/2010. I recommend that you use these drivers with Windows Zero Configuration, and not bother with the drivers on the disc. Even the most recent drivers on the Realtek site for the RTL8192SU chip are older.
Cons: Though not a con, since it is not advertised as such, I wish they would come out with an 802.11a (5 GHz) version, which needs a good antenna even more than the 802.11g/n equipment on the 2.4 GHz band.
