Rosewill RNX-N2X IEEE 802.11b/g/n USB2.0 Wireless-N 2.0 Dongle (2T2R) Up to 300Mbps Data Rates WPA/WPA2 (AES, 64,128-WEP with shared-key authentication).Cisco CCS V1.0, V2.0 and V3.0 compliant, Vista/ MAC 1.3/10.4/10.5/10.6 Ready

Pros: Well, it's a Senao rebranded as Rosewill. That's like selling a diamond ring in a candy machine. A very pleasant surprise. This is a great buy compared to the EnGenius branded version. The added RP-SMA jacks allow the addition of higher gain antennae than what is included and the semi-rigid USB extension cable is worth several, bucks on it's own. For the price, this is unbeatable.

Cons: It's a Ralink chipset. Unlike Senao's previous adapters in this form, these don't contain Atheros chipsets. There are dongle based versions of this Ralink and another Atheros based N adapter from Senao and EnGenius, but this is the only one so far in the "EXT" form.

Overall Review: I'd place this beyond any of the comparable 2x or 3x external antenna 802.11n USB adapters out there from Linksys or D-Link, although this model will likely pale in comparison to the likely Atheros version to come. Hopefully Rosewill will pick that one up too, and maybe some of the other mini-pci cards as well.

Pros: This adapter works great. My concern when purchasing it was the Linux support. I had read that it "should" work because of the ralink chipset. I just want to let other linux users know that this adapter works fine. I use it on ubuntu, kubuntu and linux mint. For anyone interested, here is what you do: 1. Get the 2870 linux driver from the ralink website (not sure if I'm allowed to post links here, so I won't) 2. Edit the the following two lines in the os/linux directory located in the ralink tar file: Change this: HAS_WPA_SUPPLICANT=n To this: HAS_WPA_SUPPLICANT=y (note the y at the end) Change this: HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n To this: HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y (note the y at the end) 3. From a terminal navigate your command prompt to the extracted directory from the ralink tar file and issue the following command: sudo make && make install That's it! You should now...see othe

Cons: Does not come with linux drivers...(but that's ok, I found them ; )

Overall Review: I ran out of room in the Pros box. OK, you should now see the driver under Restricted Drivers, if not just reboot. This is what worked for me and I've no problems and great signal and strength from quite a good distance away and through a concrete wall, a floor and another wall.

Pros: Works great! Awesome reception. Tried on Windows 7 64Bit Professional Home: Auto detected and installed flawlessly. Currently using on Linux Ubuntu 9.10. The 2 Antenna can be removed. Small enough to carry everything in your pocket. Rubber feet for setting on a flat surface or clip for clipping to back of your laptop screen.

Cons: No Linux drivers. But that's okay, I got it working. The nice metal-mesh usb cord is too short to use with the adaptor connected to top of your laptop screen. However it does come with a longer not as cool looking cord.

Overall Review: Ubuntu 9.10 Installation (Karmic) Open a terminal and type: "gksudo gedit /etc/modprobe.d/blacklist.conf" (Type it without the quotes!) Then add the following 2 lines to the end of the file: blacklist rt2800usb blacklist rt2870usb Save the file and reboot. I have done the above Ubuntu fix on my laptop and my desktop and it worked perfectly both times. Everything is working great and I have not even touched the CD or instruction manual yet. Very easy to use.

Pros: Inexpensive, excellent signal strength, quality cables, sleek look.

Cons: This product was defective. I tried it on two machines using the drivers that it came with, RAlink's updated drivers, and Microsoft drivers. All failed to solve the problems that were plaguing this device, which included: Reset connections, disconnect, packet loss, spotty performance, slow throughput (using several standard online tests). I performed all the steps that might account for any conflicts that would degrade performance, to no avail. Connection to my router w/ this device yielded 98-100% signal and reported connection speeds from 80-260Mbps. These numbers, well in excess of the numbers reported by the currently used devices on these machines (which I disabled for testing, all the way down to the bios level), did not reflect real-world performance. The 54g on my laptop produced speed test ratings around 12-14Mbps, while the N on my desktop topped out at 24Mbps. These were solid and consistent, and in stark contrast to the 2-5Mbps of this product.

Overall Review: I can only assume that this product was defective based upon the generally positives reviews. These issues occurred on two fully updated Windows 7 x64 systems. However, this is the second RAlink model that has given me this sort of issue, so I will be steering away from them in the future.

Pros: Great reception, easy to install, fairly long cord. Tried it first with my Linksys WRT54GS router and went from 3 signal strength to 5. Then I set up my new Trendnet 633GR router and have always had "Excellent" signal strength, with a solid 270 Mbps.

Cons: It takes up a USB port, and, while the footprint is admittedly very small, it obviously takes up at least some desk space, whereas the PCI card adapter that I was used to did not. A very small price to pay, as having the antenna sandwiched between the wall and the back of the computer never seemed like a great position for maximizing reception.

Pros: Very nice sensitivity. When upstairs, I see about six of my neighbor's routers (separate houses). How's *that* for range?!? The Rosewill (and then RaLink) software showed me their channels, and I could pick one to avoid interference w/ my neighbors. Also let me know which weren't secured... <EG> Works fine w/ my Netgear WNR3500 as long as I use WZC. Got almost 400kbps from 2 houses away from the unsecured neighbor w/ the D-615. Get tons of N2.0 speed anywhere in my house. Worse case looks over 150mbps anywhere, which is enough to handle most file transfering tasks, incl. multimedia. Cool!

Cons: Couldn't get the Rosewill software to connect to the WNR3500; forced to use WZC. To be fair, both Netgear 108g adapters I tried also didn't want to connect using their software either. Finally got one to work, but basically I blame Netgear, and not Rosewill. My real beef? Over a 10db difference in the strength of the signals picked up by the two antennae. I really don't think that is appropriate. Orientation, location - they don't make a difference. Neither does swapping the physical antennae. Maybe a bad solder/crimp connection inside the unit. Had that w/ a refurb router once and fixed it after opening it; don't think I should have to do that w/ this, though.

Overall Review: Those two antennae sticking up behind the laptop screen are the cutest thing. That's why it's my favorite martian!!

Pros: Really good range ( i'm about 150 to 200 feet away from my router) and windows shows 270 Mbps Very Good to Excellent. I don't have to reset it all the time like i did with my Belkin ( small black thumdrive looking N nic with a dock)

Cons: Kind of odd looking, but I kind of like that.

Overall Review: I play WoW or stream videos all the time no problems.

Pros: Have had no issues and was quite easy to install (took 7 minutes before it was ready to use). The only limitation is the limitation of my wireless router.

Cons: It didn't link directly to my cortex and let me view the internet without a computer?
