Bests & Worsts Reviews from Amazon

My home office is located in the basement directly below the placement of the router on the ground level. I noticed that my laptop (Dell Latitude) started dropping the wireless signal frequently (about every 30 - 90 minutes). The computer is about 5 years old. After doing some troubleshooting, I concluded the wireless adapter was likely beginning to fail. After researching options on Amazon, I settled on this wifi adapter. I received the adapter yesterday. I am running Windows 10 Pro. I inserted the wifi adapter into a free USB slot, and Windows 10 installed it perfectly. Since I installed the adapter, I have not lost a wifi signal and the wireless performance in noticeably faster on my machine. The four star rating has nothing to do with the performance of the wifi adapter. I gave it four stars because the instructions and CD disk are only valuable if you are running older versions of Windows (Win7, XP, Vista). This could be confusing to someone who is a novice at dealing with these kinds of issues and who is running Windows 10. If your current wireless adapter is not completely dead (which was my case), you must disable your current wireless adapter. To do this on Windows 10 go to Control Panel/All Control Panel Items/Network Connections. Select your current wireless adapter (it should be showing some active bars) right click and chose "disable" from the context menu. Now select the new wireless adapter. On my installation it comes up as Realtek RTL8811 AU wireless LAN 802.11ac USB 2.0 Network Adapter (so don't be surprised if you do not see the brand name of the device - USBNOVEL). Right click on this device and chose enable from the context menu. Your new wireless adapter should show active bars and work perfectly. I am pleased with the performance of this device. I love the low profile. Also, it has a small flashing blue light on the device, which provides a visual confirmation that it is working. My only concern is that there are no installation instructions provided for Windows 10 users. I've tried to remedy that in this review. However, it is an oversight on the manufacture's part that could cause some people to have problems with the installation.
