External USB 802.11b/g/n Wireless LAN Adapter W/antenna, 150 Mbps Review

Average Reviews:

(More customer reviews)This item is advertised to work on Windows/Mac/Linux. I'm a linux user, and this device is a pain in the butt. You plug it in and nothing works out of the box. lsusb doesn't show you what chipset is working inside: I had physically open the device to find out. It's a realtek RTL8188CUS. There is no support for this chipset in the mainline kernel (yet?). However, you can download the sourcecode for the kernel module from realtek.com. Doing so gives you a zip file that claims to support the 8188CUS, but compilations yield only a kernel module for the 8192CU chipset. Loading this module enables the detection of the device, but once you try to connect to a network, the whole system crashes. EPIC FAIL.
If I wanted this kind of user experience, I'd switch back to windows. For now, this isn't even worth the return postage as it was so cheap.

External Antenna USB WiFi Wireless IEEE 802.11G/B WLAN 54Mbps Network Adapter USB2.0 Wireless Lan USB Adapter for Laptop Noteook Desktop PC Suport Vista/Windows 7(32bit & 64bit)/Linux Review

Average Reviews:

(More customer reviews)I purchased two of these for my wife and myself because we like to sit out back on nicer evenings and wear down our laptop batteries together.
I have installed the drivers on XP, Vista, Windows 7 and tonight on Ubuntu 10.10. In order of ease-of-install I go with Win7, Vista, Ubuntu and XP. Win7 and Vista both installed the drivers without the disk, Ubuntu seemed trickier but not really. I plugged it in, ran update manager and rebooted (Ubuntu does a full reboot on my netbook in under a minute and a half.) XP was a nightmare of picking through the mis-labeled folders on the disk, giving up and finding the drivers online.
As far as performance is concerned, I saw little signal boost on XP (went from 1 bar without to 2 bars with.) Win7 and Vista both showed a steady two bar increase (1 without to 3 with) but the most impressive was Ubuntu. On Ubuntu I went from barely 1 bar without the dongle to full signal with a rare fluctuation down to 3 bars if someone stands directly in the signal path.
I've read the other reviews and they seem pretty mixed but my opinion is that this is hands-down the best purchase under $20 I've ever made.
I'm writing this review from my back patio with my Ubuntu powered Ideapad s10-3t and wireless dongle.
