Despite the performance advantage of wired network connections, many of us prefer the convenience of Wi-Fi. And when our computing devices don't have Wi-Fi controllers built-in, it's hard to get any more ubiquitous than a USB-based adapter. The speediest dual-band models fall into the AC1200 standard (as a reminder, AC1200 refers to the 2.4GHz band's 300 Mb/s maximum and the 5GHz band's 867 Mb/s peak).
Check out USB Wi-Fi Adapter 101 and and How We Test USB Wi-Fi Adapters if you would like more background.
In this piece, we take a look at a handful of modern USB-attached AC1200 adapters. After all, it is fine for manufacturers to talk about rated transfer rates and range, but we want to know which products go the distance (and for this type of device, we mean that literally in terms of throughput from range).
The AC1200 USB Wi-Fi adapters we're testing include:
- D-Link's DWA-182
- Netgear's A6210
- TP-Link's Archer T4U
- ZyXEL's AC240
Since they're compatible with the AC1200 standard, these dual-band devices can connect on the 2.4GHz and 5GHz Wi-Fi frequencies. They also work with older Wi-Fi standards, including 802.11n, 802.11g and even the original 802.11b and 802.11a.
All four products, and in fact almost every comparable USB-attached Wi-Fi adapter, support the latest security protocols, including WPA, WPA2 and WEP. In order to accommodate 802.11ac's peak performance, the quartet also features USB 3.0 connectivity capable of 5 Gb/s transfer rates, though they're backward-compatible with USB 2.0 as well.
i always get the stick up in the air and away from the pc and easily see double the performance this way. can't tell you how many times i went to a client's house to see about wifi problems and fixed all the problems by simply putting the usb stick on an extension cable and taping it to the wall above the pc. BOOM instant signal and throughput gain.
as a result i look for internal cards with antennas on cables i can raise up or usb sticks that come with extension cables. just my personal experience anyway.
tb7: check the manufacturers' pages to see if they're showing Linux drivers, at least as a first step. Not, as I think you know, that this guarantees they'll work. But it'll be a heckuva lot faster for you to do the research, than to wait on the chance that someone here has done it. Better chance is to skip USB and go PCI; for whatever reason, PCI network cards install much more often, and more easily.
my lg phone is very easy to connect to my roku stick using the miracast feature. win 8.1 had this as a beta feature and i was able to use it on my laptop. win 10 has finished this feature and it is now built into windows. sadly, the finalized version does not work on my laptop like it did on win 8.1. best i can tell is that the wifi card is too old and does not support the finalized feature. i can get over that as the laptop is a few years old.
i would also like my desktop to connect the same way but my even older wifi dongle (n rated one) on my pc does not support it either. i can't find anything in any feature list for any brand wifi stick that says it supports the wifidirect standard that miracast uses.
does anyone know how/where it is listed or is it safe to assume it is there for any newer dongle i buy. i was going to try my luck and get a new ac model assuming it would be new enough to have it supported but would rather not play the guessing game with multiple models if it is not going to be universally supported. i can't find a list of supported hardware online nor any reference to wifidirect on any info sheet anywhere. :(
anyone know anything about this as it would be nice to wirelessly share my pc with my roku stick in another room. my phone does this no problem and it is a cheap model so this is not exactly a high end feature just one that lg supports very well.
note: wifidirect/miracast is not the same thing as the dlna that some other options use. i have no interest in buying a chromecast stick or anything else other than a new wifi stick. i want to use the roku stick i already have and use daily. :)
Not many right now.
the problem would appear to be, that router support is required, and may not be all that common. That suggests support in adapters will be slow.
i have been on that site and played with the search feature but was not able to get this subcategory. i only found a bunch of monitors and routers that worked :(
but hey thanks. now maybe i can finally figure out what i need to buy. book marking that search so i can find it again :D
Well, I'm building a mini-ITX build for the living room, and the only PCIe slot will be consumed by the GPU. There are motherboards with WiFi built in, but there are better boards that don't. So, this is a very good solution for those kinds of builds, as well.
interesting article but that goes against what i thought wifidirect/miracast does. the feature uses the wifi cards in both devices to make a direct connection and pass data between them. a router should not come into play here. i think the article is saying the router will able to connect through miracast and then anything connected to the router will be able to use the data. at least this is how i read it :)
for instance just for giggles last time i was in sam's club i connected my phone to one of the lg tv's (miracast actually recognized about 10 different ones i could connect to) and mirrored my screen to the oohs and aaahhhhhs of the other shoppers who did not now they could do this. now this was done without any wifi connection at all. i was not on the store network and the tv was connected to none either. a couple other shoppers pulled out their phones and in a few minutes of showing them where the settings were, we had about 6 screen going with our phones mirrored.
this is why i read the article the way i do, since i know no actual wifi is needed, only compatible wifi cards. this is how it kills latency and such by being a direct connection between the devices with no middle man. it really is a neat feature and once it takes off, we'll all wonder how we lived without it. i watch movies from my phone to my tv all the time since it is easy to do and much easier than connecting my pc to my tv in the other room. hence my wish for a wifi dongle that works so i can do this from my pc and save my phone battery some :)
