2 out of 5 eggsInstall Process for Win7 64bit

Pros: After a lot of trial and error, it works

Cons: Erroneous documentation - Driver errors. Lack of speed and 5ghz capability

Other Thoughts: If you have windows 7 64 bit you'll need to run the installer in compatibility mode (winxp sp3 worked for me)...otherwise you won't be able to enable the adapter. Speed is a bit slower than my former powerline connection but I'll give it a shot for the time-being. The usb hub that it came was is a glorified 2 foot extension cord...

5 out of 5 eggsBesides being a dual band Wireless adapter is a portable router and a media server

Pros: I originally got the N900UBE to use it with a laptop that came with an integrated wireless adapter up to 54Mbps. However, since I read the manual and realized that this could be much more, I’m using it also as a portable router. It’s a versatile gadget, in addiction to its high speed, it can be used as an Access Point, a wireless client, and my favorite, as a repeater of my router. Yes, if I need to share a connection in a part of my house that doesn’t get a strong signal from the main router, this can be used as a repeater. For instance, during the summer we like to sit outside and enjoy the good weather, a shared Wi-Fi connection is a nice thing to have on the back porch.
I do have a portable router, but it’s about the size and the weight of a Smartphone, and likewise needs a Li-ion battery. So, if having to choose between taking that one and the N900UBE on the road, the later wins every time.
When traveling with the family this type of portable router comes handy because most of the time a table or a Smartphone can’t get the same Wi-Fi signal strength from a public access point, but an adapter like this can, and then that the Wi-Fi signal can be shared with others devices.
The included setup CD gives the options to install only the N900UBE drivers or the drivers and the utilities. This is one of those occasions that one benefits from using the included utility, because it’s the key to unleash the power of this device. The Ralink Configuration tool is one of the best I found included with a wireless adapter.

Cons: It’s not really a bad cons, but even if the included utility will install easily, one needs to learn how to properly use the software and the adapter, depending of the mode of choice. It comes with a well-written user’s manual in pdf file format, but it requires time to master its use.

Other Thoughts: The bottom line, the N900UBE is a good investment, because it can be very useful in many scenarios. I tested at home first, just to be sure it would perform well, and it does. It’s a multiple-use adapter, one that weights very little and it can be carried around without any problem for when it’s needed.

define the linux kernel source include file path LINUX_SRC
modify to meet your need.

3> In os/linux/config.mk
define the GCC and LD of the target machine
define the compiler flags CFLAGS
modify to meet your need.
** Build for being controlled by NetworkManager or wpa_supplicant wext functions
Please set 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y'.

5 out of 5 eggsGood for Windows not sure abgout Linux Mepis

Pros: Plugged in unit and windows did not have driver but I expected that put in CD installed driver with Ralink software. windows did what Rosewill said about not installing driver installed anyway like instructions say after installed, setup my connection which was no problem and on internet with ralink software managing it saw no problems there, got about average wireless connection speed for our service based on using Edimax Nano adapter then uninstalled and just installed driver no problem used windows to connect to the internet and got about the same speed results as with ralink controlling the connection. after about an hour of using it connected it got warm to the touch but by no means hot.

Cons: then had my Linux friend try to install it on a Mepis box and it tried to use existing drivers but they were not compatible with chipset and it acted up. He then removed existing driver and installed the one from Rosewill website. After about 3 hours of tinkering with it he was unable to get the unit to work in his version of Linux, he did not know if it was his fault or a problem with the driver but suspects he is to blame for it not working, he has been a Linux user for the past 14 years.
the unit is definitely a bit bulkier than most but it has an extra antenna that should allow for better range which I could not test in our home, my computer sits 20' from router and Mike's Mepis box never got it to work so no idea there

Other Thoughts: For Windows 7 Pro I see this as a viable option for wireless internet but with what friend found I would question as to whether or not it is acceptable for average Linux user.

4 out of 5 eggsGood, but could be better

Pros: The performance of this adapter on the 5GHz band has the potential to be very good. It immediately connected at 450mbps, although it did fluctuate between 250mbps and 450mbps during testing. With the antenna pointed directly at the router, which was two rooms away, I achieved between 84mbps and 120mbps (12-15MB/s). This is a very good result.

Cons: (1) Performance was all over the map, for one simple reason: this adapter is completely unidirectional.

On the 2.4GHz band, it performed only slightly better than a typical inexpensive single-band adapter or built-in wireless. It achieved between 20mbps and 32mbps on two test systems, with the best result of 32mbps right next to the router, translating to just over 4MB/s. The problem is definitely the unidirectional nature of the adapter. For instance, on my notebook test system, I could increase transfer speed from 24mbps to 31mbps if I turned the notebook and pointed the adapter antenna straight out in the direction of the wireless router several rooms away. This is impractical for regular use, and impossible on a desktop.

The situation was similar on the 5GHz band, although speeds were much higher. But again, the adapter is completely unidirectional. When using it on my desktop, which is against a wall, the transfer rate was a disappointing 40mbps (5MB/s). But when I used a USB extension cable I had on hand and pointed the antenna directly at the router several rooms away, I achieved sustained transfer speeds of between 84mbps and 120mbps (12-15MB/s), as noted above.

(2) The instruction manual has multiple errors in it. First, it indicates that you install the adapter prior to installing the drivers, and at the end indicates that you must install the adapter after installing drivers. The latter is correct. Also, it indicates that you should search on the CD-ROM for the drivers manually, when an installation program actually pops up upon inserting the disc. Simply click on Windows OS or Mac OS to install.

(3) The included Ralink software is not particularly intuitive, for instance in regard to how to connect or input passwords, and unless you are technically-inclined, just pass on installing it and use the built-in Windows wireless networking application.

Other Thoughts: So, how to rate this adapter? Honestly, without the ability to position the adapter appropriately, this is a 3-star product. It's simply too unidirectional for practical use on either the 2.4GHz or 5GHz band. If you're paying this much for an adapter, it must outperform cheap adapters without requiring the user to jump through hoops. I see that Newegg is currently bundling it with a USB cradle, which it should have come with in the first place. For that reason, I'll give it four stars, but unless you get it bundled or have one on hand, I do not recommend this product.

Note that the device will not be recognized automatically by Windows - if you do not have an optical drive in your system (for instance, an Ultrabook), you will need to download the drivers from the Rosewill website beforehand from another active Internet connection.

All tests were conducted using a high-end 802.11 dual-band wireless router.
