Why do Wi-Fi repeaters slow down speed at close range?

If you have purchased a new Wi-Fi repeater system, whether one from your local store or a more complex kit like the Alfa WiFi Camp Pro 2, you may have decided to give it a test run at home in the same room as your router. 

You may have been surprised to see that at 100% signal and not much distance between your computer, router and your repeater, your speed through the repeater was slower than when directly connecting your PC to your home router's Wi-Fi signal. But the repeater was supposed to make everything faster, you thought.

Repeaters are designed to take a fair/weak Wi-Fi signal and rebroadcast it (repeat it) as a  new Wi-Fi signal that will cover additional area where signal could not previously be received well. When you setup a repeater at close range to a router, you are detouring data packets through an unnecessary route. The best way to describe it comes from this post we saw on CNET forums:

PC to router = 1 request and 1 reply.

PC, repeater = 1 PC request to repeater, 1 repeater reqeust to router, 1 router transfer back to repeater and 1 repeater transfer back to PC

What exactly does this mean? Wi-Fi is a half duplex technology. This simply means data is sent then received (with an Ethernet cable connection, data is sent and received at the same time). When you use a repeater to extend coverage, you are creating a second half duplex signal that data must travel through, which slows down packet rates. When you set up your repeater where coverage is fair or weak, it will extend signal further to areas where you could not get signal, and you will go from having weak signal to having a stronger signal and faster data speeds. However at close range, the repeater cannot serve its purpose of extending coverage because coverage is already good, and actually will cause your speed to be slower.

Bottom line- definitely test your repeaters like the Alfa Camp Pro 2 inside your home before going on the road to familiarize yourself with the setup process and ensure all hardware is working. But don't rely on close range speed tests to determine if the equipment is doing its job.

The best Kali Linux compatible Wi-Fi USB adapters

What Wi-Fi USB adapters are the most popular for injecting in Kali Linux?

A recent poll from WirelesSHACK shows these results:

The Alfa AWUS036NH and the AWUS036NHA are clear cut winners (graphic source https://www.wirelesshack.org/best-kali-linux-compatible-usb-adapter-dongles.html)

The AWUS036NH is a 2.4 GHz product with the Ralink (Mediatek) RT3070 chipset. The AWUS036NHA is also 2.4 GHz and uses the Atheros AR9271 chip.

Both models are excellent choices with great performance. If you need a Wi-Fi adapter for Kali Linux, Kali users have spoken, and their choice is one of these two.

New firmware for Alfa R36A and Alfa WiFi Camp Pro 2

IMPORTANT NOTE: Never attempt a firmware update over WiFi connection between your device and the R36A router. You must use an Ethernet cable. If your device does not have an Ethernet port, locate a device that does or purchase a low cost USB-to-Ethernet dongle.

January 2019- If you own an Alfa R36A router (standalone version or the version that ships in the Alfa WiFi Camp Pro 2), we have firmware updates available for each one.

To get the new firmware (v1.15) for the Alfa R36A retail box version, click here.

To get the new firmware (v1.17) for the Alfa R36A that ships inside the Alfa WiFi Camp Pro 2, click here.

Please note the firmware files are not applications, so you cannot open them like you would a normal setup program. Instead, once downloaded, follow these instructions to upload the firmware files inside the R36A interface.

Do you need to update?

Both of the above files have range and performance improvements. If you are happy with your current performance, then you do not need to update. If you have purchased recently (this article was published 1/17/2019), you may already have the latest firmware and do not need to update. From inside your R36A administration area, click the Status tab to the left and check the firmware version at the bottom to see what version you already have.

What's the deal with SIP protection in Mac OS?

[Editor's note: the comment section is not regularly monitored. For tech support, visit our support page. At this time we can only provide support to customers, though we can also answer any questions about compatibility.]

If you own some of our products advertised as Mac compatible, you may be in a situation where they just aren't working. The most likely issue is that on Mac OS 10.11 and later, Apple has SIP protection enabled by default.

What is SIP protection?

Apple defines SIP protection as "...technology in OS X El Capitan and later that's designed to help prevent potentially malicious software from modifying protected files and folders...it restricts the root user account and limits the actions that the root user can perform..."

In other words, it is designed to limit capabilities of your Mac system with the intention of preventing unscrupulous software from doing things it shouldn't. But it also blocks legitimate software from being installed outside of the Apple app store (FYI Apple does not approve WiFi driver software for the app store).

SIP protection locks down system folders to prevent third party software from writing to them. So to use Mac driver installers for most of our Mac compatible products on 10.11 and later, you have to disable SIP protection. Fortunately this is easy to do, read on.

Does disabling SIP your Mac less safe?

It makes it as safe as it was in Mac OS 10.10 and earlier. You are essentially just allowing applications to write to your system folders again. As always, never run any application from a source you don't trust, and always use antivirus software.

How to disable SIP protection

To use any of our Mac installers on most 10.11 and newer Macs, you will need to first disable SIP protection before installing the software. If you already installed the software, uninstall it. Then take these steps to disable SIP protection:

1. Click the Apple menu.
2. Select Restart...
3. Hold down Command key and R key to boot
into the Recovery System.
4. Click the Utilities menu and select Terminal.
5. Type csrutil disable and press return.
6. Close the Terminal app.
7. Click the Apple menu and select Restart...

Now install the software desired and you should be able to use your product.

New product: Alfa R36A USB-WiFi Router/Repeater for AWUS036NH/NEH

Many of you may be familiar with Alfa Network's groundbreaking R36 router from a few years back. This was the only router of its kind that allowed you to use an Alfa USB Wi-Fi adapter to extend range of a distant Wi-Fi signal and share it as your own private hotspot.

Alfa has released a new version of this router called R36A, which features internal enhancements offering users faster throughput speeds, better performance, and the ability to handle more users online at one time. It also has an overhauled 2-screen setup interface, reducing setup time and making the experience much easier.

It remains a 2.4 GHz product so as to have maximum power (dual band devices must have less power per FCC regulations).

Existing owners of an R36 should know before upgrading that R36A is compatible with AWUS036NH, AWUS036NEH, and Alfa Tube-U(N) USB Wi-Fi adapters. Older models AWUS036H and AWUS036NHR are not compatible with R36A.

Want faster throughput and a VPN service all in one? Get Speedify

If you have followed our blog for some time, you may recall us mentioning Connectify, a software tool that allows you to create a hotspot on your computer and share a Wi-Fi connection. Now the company that makes Connectify has does it again with Speedify.

Speedify is an exciting new service that allows you to bond more than one Internet connection together to increase your Internet speed. For example, if you are using one of our Alfa Wi-Fi USB extenders to get better signal to a network, and you are in a location where your built-in Wi-Fi card still works, you can bond the connections together and essentially use them both at the same time.

From the Speedify web site:

"...The technology behind Speedify’s connection magic is called Channel Bonding. We combine multiple Internet connections – Wi-Fi, cellular, ethernet, etc. – to provide increased bandwidth, lower latency, and better reliability."

Speedify also includes VPN service which helps encrypt and protect your data even when you are connected to an open Wi-Fi connection. Rokland strongly recommends VPN service to all users of Alfa R36A and Alfa WiFi Camp Pro Kit 2.

*Rokland is not affiliated with Speedify and is not receiving any compensation for this post. We are writing about it simply because it could be of great benefit to many of our customers.

Speedify does have a free plan for low-bandwidth users and monthly and annual plans for those who use more data. Read more here.

Using Alfa AWUS036NHA on Microsoft Windows 10

Alfa has not released a driver package for Alfa AWUS036NHA (Atheros AR9271 chipset) beyond Windows 7.

However it has come to our attention that AWUS036NHA can be stable on Windows 8 and 10 using this third party driver. This driver was made for a different brand product which uses the same AR9271 chipset. Note that after installing, the device will appear in Device Manager as "TP-LINK Wireless USB Adapter" instead of Atheros or Alfa. This is because TP-Link is associated with Microsoft as the Device Developer ID.

We have tested the driver extensively and it appears to work with the Alfa AWUS036NHA well. However it should be considered a beta driver until further notice.

Using Alfa AWUS036H on Windows 10

Note that we do not advertise or promote the use of AWUS036H on Windows 10. We have better and faster options available for purchase such as the newer AWUS036NH and AWUS036ACH.

But if you already own an AWUS036H and find yourself wanting to use it on Windows 10, here is a quick way how to do it.

The last driver made for this item was December of 2009 for Windows 7. The installer package for Windows 7 does not work on Windows 8 or 10, it just says "incompatible operating system" when you try and run it. So you need to run it in Windows 7 compatibility mode.

Step 1: Download Win7 driver (http://www.rokland.com/mask/drivers/alfa/awus036h_windows_7.zip)

Step 2: Open the downloaded zip file and extract the contents to a place on your computer you can find.

Step 3: Navigate to where you extracted the contents. Right-click the Setup.exe program and select Properties. Click the Compatibility tab and under Compatibility mode choose "Windows 7" and make sure the "Run this program in compatibility mode" is checked. Then click Apply and exit the Properties window. This should bypass the compatibility error.

Step 4: Run the Setup.exe program in full and restart the PC when done.Connect your AWUS036H to the PC and use as normal.

The Gadgeteer on Alfa AWUS1900: Light weight but powerful

The review is in- The Gadgeteer, a popular online gadget and tech site, has taken a first hand look at the Alfa AWUS1900 quad-antenna 802.11ac AC1900 Wi-Fi USB adapter, and you can read all of their comments here.



Since launching earlier this year, the Alfa AWUS1900 has turned heads with its unique look, and its unique place in the market as a low cost USB AC1900 upgrade. If you own an 802.11ac router, especially one with three or four antennas, in addition to getting better range, the AWUS1900 will also give you improved bandwidth capabilities back to your network compared to an internal Wi-Fi card built inside a laptop or desktop.
