Unbelievable
I would like to preface this with the fact that I've only had this a few days, but in those few days it has been amazing. I have an older computer that doesn't work with 5G. I was forced to change my modem to a 5G modem by Xfinity. They divided it up into 5G and 2.4. This computer (which I love) had to use 2.4 and it was worse than when I had dial-up. (Yes, I'm that old.) Anyway, for me it was not plug and play. I did have to go to the website and download the driver. But their instructions are so detailed and so good. I mean they really go into every circumstance that could happen and tell you how to deal with it. Before, I was lucky to get 35 MBps. Now, look at the speed test results I get. Over 200 MBps. So far I am thrilled with this! It is now June 21, 2024 and I am sad to report that this gadget no longer works. I turned on my computer today and it was no longer working. I was so happy how well this worked, but if it only works for a couple of months it is not worth buying. My advice, try another adapter. This one does not work for long and it is not worth paying anything for a device that only works for a month or two.

You can count on customer service- they will make it right!
Well, to be honest, I did have a problem with this adapter. I was getting very low speeds. I contacted Customer Service and Lynn tested my system and confirmed it wasnโt working properly. She then expedited a new better one. It arrived the next day. The new one works great! Getting very high speeds now. Lynn then called a couple days later to follow up and make sure it was working properly. Thatโs great customer service!

Good outfit to work with
Installation was really easy, with auto-install driver included on separate USB drive. It turned out to be quite slow, so I emailed the provided address and worked with Lynn at 9Plus to resolve. She ultimately sent me a different adapter which is working fine. Good company to work with.

Big improvement in my internet speed and reliability
This is a definite upgrade for my HP laptop which relies on a USB network adapter. It's faster and much more stable. Installation can be a little tricky if your system can't just plug and play -- but I contacted the manufacturer's website and got assistance through its chat function. The person who assisted me did a great job and installed the necessary driver through our web connection. Very pleased with this new device. It's enabling me to take full advantage of the top speed of my internet service.

SEE EDIT! Great product and wonderful customer service---AT FIRST!
I am writing this as an edit for my review (see below). The product worked great the first time, but when I went to go back online a few days later, it couldn't find any available networks. I went round and round trying to get it to see any available networks. SANA was not quite as solicitous with these follow-up contacts. (Perhaps because I had given a rave review already...I don't know!) I finally got a response when I sent a text indicating that I would have to go and amend my first review, because customer service was great the first time, but completely lacking this time. I was told to unplug/replug the device; if that didn't work then reboot my computer (I had already done that), etc, etc,etc. It finally came down to their rep having to access my computer, go into some files and basically reinstall it. I asked the person to please tell me what they were doing as they were doing it, so I could fix it myself, if needed, at a future date--of course, that's not what happened! So it worked while they were present, but the next day it did not. I finally just unplugged it and uninstalled all its pieces and parts. It is now sitting in a box. I do not stay online when away from my computer for long periods of time, and when going back online, this product cannot find the networks without my having to jump thru too many hoops. My regret is I waited so long to unbox and try it out. It's been almost 8 months since purchase, and I'm certain I cannot return it! My network is running a lot faster now! I had trouble getting it all installed properly, and contacted them thru the chat feature on the website. As promised, I was contacted shortly after by SANA. What a wonderful customer service agent! We communicated thru text and were able to share photos of what we were working on. Sana is so patient and courteous, walking me thru step by step! Thank you, Nineplus and thank you SANA for a great product with great support!

Great Product and Great Service!
This WiFi adapter does exactly what it says it will do. On top of that, it was very easy to set up and it does come with a USB drive containing drivers for if your computer is being picky and needs a manual install. For the most part I found it to be plug and play. I will say that the NinePlus customer service is excellent. I asked if someone could check my settings and make sure that everything was set up correctly. I was contacted by two reps from the company, John and Ayman. John was able to log on to my PC and check things out and Ayman called me to make sure that things we going smoothly. Both of these gentlemen were very courteous and extremely helpful.

Reliable, no โboostโ
Iโve got it going about 40ft and through 2 walls to my router and my wifi is still decent. Though it doesnโt improve my wifi speeds for gaming at all, my wifi is normally terrible and with this my connection is still terrible but cordless. I expect if I had good wifi, that the adapter would have the same quality wifi.

Fast wifi
I have not yet upgraded my router, but even with a WiFi 5 router this thing is reliable and fast on Windows 11. Drivers easy to install as well. No complaints.

Fast Wifi Speed
I was able to use this for my desktop PC to get wireless connection to my router and the speed was reliable and fast. So far there is no drop off so I can comfortably game with this adapter, it was also easy to set up as it has 5ghz and 2.4ghz, both frequency range were available in my modem.

Works well but not plug and play setup
Good replacement for the built in laptop wifi card that failed. However setup required a bit of trial and error and not plug and play setup. None of my computers recognized the dongle when inserted into the USB-A ports (tried them all and even rebooted). This made it harder to obtain the install software on the key. Fortunately the instructions had a link to the manufacturer website which I used to download from another computer to a USB key then moved to the laptop for install.

Superb!!!
It was super easy to set up, and my connection has been fast and stable ever since. It really improved my streaming and online gaming experience. Plus, its small size doesnโt block other USB ports, which is a nice bonus. Highly recommend it!
