Enables you to connect to Wi-Fi that would have otherwise been out of your device’s coverage areaĪ Look at the Types of Wi-Fi Antenna An example of a directional Wi-Fi antenna.Bumps up the internet speed of the wireless signals that are in range.Increases the range of your built-in wireless card by 200 to 300 yards.This device offers the following advantages: Poor internet connectivity could cause online clients to walk out the door, as a stellar internet connection is necessary to deliver a great customer experience.Ī computer Wi-Fi antenna can boost the internet connection range of your computer. As a result, you’ll experience disconnections or sudden drops in internet speed. This means that you could easily find yourself out of range of local Wi-Fi signals. The range of these cards, however, is limited. Why Get a Wi-Fi Antennaĭesktop and laptop computers usually have a built-in wireless card that allows the device to wirelessly connect to the internet. On the other hand, the receiving antennas pick up the waves containing data and turn them into signals for the device. The role of transmitting antennas is to convert electrical signals into EM waves to send information packets. Wireless networking devices, such as tablets, wireless routers, computers and smartphones, have transmitting and receiving antennas. An external Wi-Fi antenna turns these waves into electrical signals, and vice versa. These wireless signals consist of electromagnetic waves (EM waves) filled with packets of information. Wireless devices use radio waves to communicate with each other. This piece of tech equipment facilitates the internet signal that people use to surf the web, play online video games, get in touch with people via social media and take care of their online business.

A Wi-Fi antenna used indoors. Enjoy Better Internet Connectivity Wherever You Go.I spent a couple of hours installing the latest drivers, changing various settings, but I couldn't improve upon these results.įor what it's worth, my adapter settings are set to:Ĩ02.11a/b/g wireless mode = Dual band 802.11a/b/gĨ02.11n/ac/ax wireless mode = 802.11ax (my access point is 802. My 2.4 GHz speed is still fairly poor however, only reaching about 35 mbps on average. Since I've never seen this level of performance from the internal wifi to date, I must assume the positioning of the antenna in the back/top of the box is not optimal, and moving it to the front/top is much better. Anyway, when I tested my speed on 5 GHz using the internal wifi card after moving the antenna, my download speed jumped to nearly 300 mbps fairly consistently (always > 250, sometimes reaching 350, usually around 275-300). Just for kicks, I removed the one attached to the rear and moved it to the top/front of the box next to the other antenna (I had to move the other antenna over a bit to make room for both. I was guessing they might be near the bottom, but was surprised to see they were located at the top of the box, so I wasn't sure if their location was causing the speed issues. So I decided to open the UM300 and check the location of the antennas from the internal wifi card. Note: all external wifi adapter tests were done with the internal wifi adapter disabled in Windows network adapter settings. Although I haven't opened the box to look, my guess is that the internal wifi antenna is probably somewhere in that location and that's why it gets substandard performance. So it seems there's something near the back side of the box that generates interference with wifi. If I use the nano adapter plugged into a six inch USB extender cable (3.0) and plug it into the same rear USB port, but run the cable so the adapter is in front of the box, the download speed is closer to 200 mbps. I believe something in the box creates some interference on the rear side of the device. Even with the machine turned around on my desk, using the adapter in the rear USB port results in lower wifi speeds. I do believe there is some interference emanating from the box, however, because I've tested the nano USB adapter in the front USB port and it gets 200+ down, but the same adapter in the rear USB port often has trouble connecting at all, and if it does, gets < 100 mbps down. The nano USB adapter pulls about 200 - 250 mbps down, while the internal wifi maxes out at around 100 mbps. Making the changes to the 5 GHz channel width helped, but compared to an external USB wifi adapter (even a nano adapter with no external antenna) the internal wifi is poor. I have the UM300 and its wifi is also less than stellar.
