TP-LinkUSB Wifi Dongle 300Mbps High Gain Wireless Network Adapter for PC Desktop and Laptops. Supports Win10/8.1/8/7/XP, Linux 2.6.24 - 4.9.60, Mac OS 10.9 - 10.15 (TL-WN822N)

Here's my situation. I live in a home with 2 stories and have combating my network issues for months. Due to the configuration and number of devices/components, I had to place my broadband modem/router upstairs while my home office is in a downstairs room. Aside from running my own cabling in my walls and between floors, I've tried every solution to try & get satisfactory Ethernet connection in that office. In my original solution, I opted to go for Powerline AV but no matter which adapter I used (I used both Netgear and TP-LINK brands), I cannot get a good enough speed to the office. What's strange though is that under other outlets in the house, I can get a good connection. I'm not an electrician, so I'm not sure why my Powerline adapters simply just stink in the home office room. Documenting the speeds, both Powerline adapters would at most, get slightly over 1Mbit (yes, just ONE) speed to my PC. This is 100x less than your standard 100Mbit Ethernet connection. On top of that, my Home Internet via Comcast is 50Mbit. Can you imagine a speed slower than a T1 between devices in your home? Yes, it was that terrible.So I opted for the next logical solution. Using a wireless USB NIC. A friend of mine let me borrow his adapter but I could only pull about 20Mbit from my wireless router to my office PC. Even my work Lenovo laptop and my speeds would be roughly in the 20Mbit to 25Mbit range (connection speed was just good, floating between 3 and 4 bars according to Windows).Thinking about it long and hard, I finally decided to try a high gain adapter. I remember using high gain antennas and adapters for wirelessa couple years ago in my previous job and I knew after about a decade, there should be a nice niche consumer market for these devices. Lo and behold, I found this adapter on Amazon.The end result? Amazing. My connection speed is considered "excellent" via Windows and the RSSI (received signal strength indication) sits at in the -60s (which is a good signal). When performing a speed test w/ my Internet, I easily hit the max 50Mbit. Finally I can download at the speed in which I pay for!! Transferring between my home office PC to a laptop PC using 802.11g achieved expected results as well. No more slow-mo WiFi.The *ONLY* caveat I have with this adapter is that it operates only on the 2.4GHz spectrum of 802.11n. Without going into too much detail, the "best" 802.11n networks utilize the 5GHz space due to the availability of non-overlapping channels. With 2.4GHz networking, you only have 3 non-overlapping channels in that spectrum. Since 802.11n works by combining multiple channels, you only really have a limited number of channels to work with. Bottom line is that if you live in an apartment building or some close quarters where other wireless routers exist, you could get some interference if you try to use 802.11n over 2.4GHz.Luckily for me, my neighbors are all using the same 2.4GHz channel, so I haven't run into any problems (yet).Highly recommended adapter for those wanting INSANE range for a CHEAP price.

I'm am quite pleased with this product as it meets my criteria quite well. I was looking for an adapter for my home office so that I had a nice quick link to my home server, and to make use of my external bandwidth (which has exceed the speed of my g network for the first time ever!).My criteria1) I did not care about size as I was really only using it in this one location2) I wanted to get a maximum speed out of my link3) The device needed to be relatively easy to set up with the 3.0+ kernels as well as some older ones (one pc srunning ubuntu 10.04).I first got the Asus n-13 thinking naively that it would "work" best with my asus n-16 router and they stated linux support. Unfortunately asus chose another chip for their newer dongles so I was out of luck in 10.04 (it would freeze my desktop on removal as well 0 nice).That was quickly returned and I gave this a try because it has an atheros chip reported as well supported under Linux (via the ath9k_htc module)The model I received was the TL-WN822N ver 2.0. It worked out of the box with 64 and 32-bit ubuntu 12.04 and 64-bit 10.04. Windows support seems strong though I did not test that yet.I get a "reported" connection speed of 300 Mbit/s to my asus n-16 router at about 40 feet, one floor and two walls.The reported speed is not so useful. I used iperf to a both a wired network machine and to my router consistently shows about a 194Mbit/s to 90 Mbit/s throughout the day without anyone using the wifi. In practical terms its about 19.4MBytes/s to 10.3 MBytes/s which slightly exceeds my write speed on my old server external drives so it works great for me.I highly recommend this adapter!Notes:iperf is a network tool which is useful to test raw network speeds while avoiding potential bottle necks such as harddrives or the protocol you are using to transfer a file. It works on all major OS's (and there is a great android version too). see [...] for more info on how it works.To take full advantage of the N wifi spec you need either a dual band router and adapter and use a chunk of that spectrum (this one is not 5Ghz capable) or set the channel width to 40 Mhz. The latter is not very nice to do if you have a lot of neighbours nearby (like in a highrise condo). I also run the router for n clients only (I have an older g router to handle those clients). More info on bands here: [...]Also remember to get N speeds you need to use wpa2 with AES or nothing at all - WPA1 or wep slow it down to g speeds.
