WiFi can lack at times and depends on many factors as to why it is not transmitting well.
Many things can disrupt a WiFi signal from walls and other wireless devices, to a microwave oven.
Even though there are many things that degrade a signal there are things that can be done to get a better signal.
Having a good router is a start but individual devices also need to be able to send and receive a good broadcast.
UBS adapter with high gain antennas are one such option to help a laptop or desktop send and receive better and improve performance.

Our Picks for Best WiFi USB Adapters with High Gain Antennas
TP-Link N150 Wireless High Gain USB Adapter (TL-WN722N)
The TP-Link WN722N is a notorious USB adapter that has been available for awhile and still going strong.
One of the things that makes it stand out is the wireless chipset it uses Atheros AR9271. This chipset allows for it to go into monitor mode which is necessary when Pen testing a WiFi signal.
For this reason it is widely uses in the Pen Tester community for doing wireless attacks.
It also has a 4dBi omni-directional antenna for improved coverage.
While still widely used it is only a 2.4GHz dongle and wont work in the new 5GHz frequency. Since most all router are dual band and work in both ranges this isn’t usually a problem.
It is a 802.11n adapter so it also doesn’t work with the new 802.11ac protocol and will default to Wireless-N speeds (150Mbps).
With that said for the price it is still a very popular unit and a nice upgrade over a built-in wireless or adding better distance to a device.
Reliable, low cost, durable, along with multi purpose use make it a unit worth looking at.
Alfa Long-Range Dual-Band AC1200 Wireless USB 3.0 Wi-Fi Adapter w/2x 5dBi External Antennas – 2.4GHz 300Mbps / 5Ghz 867Mbps – 802.11ac & A, B, G, N
Alfa AWUS036AC is a nice unit built for long range and all the new protocols.
It has USB 3.0 so there will be no bottlenecking at the USB port, as long as the computer has USB 3.0 otherwise it will default to USB 2.0 speeds.
The newest 802.11ac WiFi protocols are used and is a dual band dongle that works in both 2.4GHz and 5GHz frequencies.
Alfa is another well known manufacture in the Pen testing community but the AWUS036AC does not go into monitor mode and is built for speed and range.
It has 2 external removable 5 dBi antennas, being able to remove them means they can easily be upgraded to a larger 8-12 dBi antennas.
A cradle is included with it to move it about if necessary for better reception or it can plug straight into a USB port.
If you are looking for the best range and newest protocols the Alfa AWUS036AC is definitely worth a look.
