Edimax 2-in-1 Wi-Fi 4 802.11n N150 + Bluetooth Low Energy (BLE) 4.0 Combination Adapter for PC, Wireless Nano USB Adapter Dongle, 150Mbps, Windows...

This is the best thing to add to an original RPi that only has 2 USB2 ports without any wireless support, or really any older laptop computer with limited USB ports. It also functions in really old computers with USB1 ports, with much slower speeds. Pros: + bluetooth AND WiFi n + compact size + simple USB + driver support for many older operating systems + automatic driver install in Win10/11 + rtl8xxxu support in linux Cons/improvements: - linux support is flaky with older versions - bluetooth limited to 4.0 - no 5GHz band WiFi support - no bluetooth support in Mac Note: Rasbian/RPiOS (maybe all linux?) requires removing the blacklist on the rtl8xxxx driver in order to work: echo "" > /etc/modprobe.d/blacklist-rtl8xxxu.conf && reboot

The overall rating of this product isn't bad. I ignored the 1-star ratings which commented on the constant disconnects and slow speed. Initially, it seemed to work fine. Disconnects about every hour, which I attributed to the small size and limited antenna. Gradually, the disconnects became more frequent and now it won't stay connected long enough to load a web page and click on a link. Although I am just inside my return window, I think I will throw it in the trash rather than let some poor slob pick up the same piece of junk. BTW, I bought two and both perform the same.

Currently using this when the wifi card of my Surface Pro 3 broke. At first, I was skeptical, but it has actually worked fairly well. The Internet speed is acceptable (rarely any buffering when watching videos on YouTube or Netflix) and the Bluetooth connection is solid as well. Connecting to wifi is sometimes slow/doesn't connect to networks automatically, but this is a relatively minor issue for me. It also gets a little hot after a few hours, but I haven't noticed that this has affected its performance. The installation was a bit tedious, but I would recommend looking at the top comment for this device by Michael Ronayne for guidance. After following his instructions, I was able to install the device with no issues. I have had this device since April 2017 and so far (fingers crossed), this device is still working smoothly. Given the small form factor and usability, I would recommend this if you are having any wifi/bluetooth issue.

I purchased this item for use with a Dell OptiPlex 745 running Windows 10. It took several steps to get it to work, however. The drivers that are included on the mini-cd that ships with the product DO NOT have Windows 10 drivers included. You must go to the edimax website and download the drivers for Windows 10. What's initially frustrating is that the 7611ULB IS NOT listed in the compatible Windows 10 hardware list on edimax's site. Only after I went searching on their downloads page did I find that version 1.0.0.3 of their software supports Windows 10. What made the installation even more complicated was that I had to run their setup application at least three times, rebooting after each failed install, until the adapter finally lit up with the blue light indicating it had power. Connecting then to my wireless router was routine and has been reliable. The bluetooth it offers is really nice and I was using it to transfer files to and from my cell phone. I also was playing the Google Play app on my phone and listening to it through the edimax adapter on my PC's speakers. I can also control the Play app tracks with the software on the PC. I also connected a Dell wireless keyboard with this adapter to my PC. The connection rate I get to my router is about 72, not the 150 the adapter suggested. I am about 35 feet from my wireless router and I have the adapter in a front USB port as suggested by edimax for better connectivity. Having nothing else to compare to, this adapter seems reliable and has been operating without any problems for the few days I have owned it. The price is decent in my opinion and so far my only complaint is that using it with Windows 10 was initially tough to get working.
