I bought this to replace an unreliable ethernet over power setup that would cut out occasionally. I found it via an article recommending wifi adaptors. The performance of this one has been flawless so far and has enabled me to get my full internet speed from the router downstairs. Far better than my previous solution! The only minus is the detachable cap which I don't know where to store.
Otherwise it's 100% reliable so you can be pretty sure this will do its job as expected. Great product.
I had ordered one of these units 3 years ago for a client who lost their wifi on their laptop. It worked great for them, so when I wanted to get a couple of my computers working on 5GHz, I order this version.
The first computer I installed the driver on was supposed to have 5GHz, but it never worked. After installing the driver for this WiFi adapter, suddenly the computer started working on the 5GHz band. As a result, I moved the adapter to an older computer. The download speeds doubled on this 9-10 year old computer. Nice! I put the second one on a computer my wife uses for school and it almost tripled the download speed of the computer.
I will always carry one of these with me when I travel as it worked better than the built in adapter in my travel laptop.
