PHYSICAL SEPARATION of the R36 and the wifi adapter:  They should be physically separated to prevent transmitter noise from one degrading the receiver sensitivity in the other.  The last installation put the antenna and wifi adapter outdoors on a pole and the R36 inside a steel-walled trailer. Best results ever!

Maximum outside operating temperature of the Alfa WiFi USB adapters is 104 temperatures and they will fail if exposed to  temperatures higher than 104.

Most notes on this page are courtesy of our customer Jim Kaness.

To date I’ve made two installations of Alfa R36 wifi router/repeaters- one sold and one my own. In one case the high gain antenna is at the top of the pole while the R36 is at the bottom of the pole to concentrate its radiation into the house. In my own case the R36 is just below the high gain antenna and can be received by my laptop 200 to 500 feet away, This email is being sent through my own “wifi hotspot”. Photos attached.

12-volt power to the R36 is extended via 18-gauge zip cord spliced into the R36 power supply wire.

The wifi adapter is in the high gain antenna.  This makes the high gain antenna available for use with tablets and newer computer operating systems.

My own R36 installation, with the R36 just below the antenna outdoors on the pole has led to the wifi adapter dying. Symptoms were very low signal strength and very low connection speed. Replacing the CUR wifi adapter and putting the R36 ten feet away from it solved that problem.

Customer Alex Crow wrote:  I bought this product with the assurance of another user of this usb adapter stated on backtrackforums that the chipset supported monitor mode. Furthermore, I was surprised that it was not only a plug and play adapter in a Linux 64 bit OS environment and that the driver was native and needed not be manually installed or compiled from source on Ubuntu 12.04 LTS. Awesome range and compatibly!!! I will be recommending this adapter to many friends ty

QUESTION: Which of these wifi cards would have the best support out of the box on Linux? and the best range? War driving etc:  AWUS036H or AWUS036NH or AWUS036NHA

ANSWER:  AWUS036H is the best for Linux out-of-the-box, best range, best for war-driving etc.

Alfa R36 802.11 b, g N, Repeater and Range Extender for AWUS036H can also be used as a 3G Router:  Enables you to repeat a WiFi connection to the internet:  The origin signal is connected to by the AWUS036H; the AWUS036H connects to the R36 by USB cable, and the R36  redistributes the internet connection to multiple Users (Desktops, Laptops, tablets, iPad)

Setup Instructions:

We recommend that you have the latest firmware installed.

You don’t have to install anything onto your laptop.

For best results, physically separate the R36 and the Alfa USB WiFi adapter as far and as physically isolated as is practical

To setup to repeat a signal from a neighboring Access Point:

  1. Use the USB cable to connect the awus036h to the r36
  2. Establish a connection to the R36 either by WiFi or by plugging ethernet cable into LAN port of R36 and ethernet port of PC
  3. Type in browser address bar: 192.168.2.1 (this is the default IP address of the R36)
  4. Click “easy setup”
  5. Click “usb wireless adapter”
  6. Click “site survey”
  7. Click “rescan”
  8. Click on the “ssid” signal you want.
  9. Click “select”
  10. Click “next”
  11. Click “done” or you can click the “ssid choice” box, and rename it, and click “done.”  At this point you are finished with the installation.
  12. Security can be added at anytime by clicking on “advanced” and then clicking on “security.”  Adding security is almost identical on basically any brand of router.
  • The R36 works fine with the Alfa AWUS036H but it also works fine with other wifi adapters that use the Realtek RTL8187L chipset. This offers 802.11b/g (11 and 54 megabit) service but not 802.11n (150 megabit).
  • Bookmark the IP address of the R36 (192.168.2.1) so you don’t have to keep remembering it.
  • When using the wifi connection to set up the R36, if you change the channel or the SSID (the name of the signal) of the R36 the change will take effect, but then your computer’s wifi will disconnect from the signal (because the ‘old’ signal is no longer there) and you will need to search for the ‘new’ R36 signal and reconnect and log in to the R36 before proceeding further!
  • R36 BOOT-UP TAKES ONE MINUTE.  Do not have a magnet near the R36 when you are trying to set it up.

Sample application for connecting to an access point up to 3 miles away:

  • High-gain outdoor antenna and close-mounted wifi adapter in a weatherproof housing.
  • That antenna mounted wifi adapter connects with a USB cable to the R36 mounted in a weatherproof housing lower down on the pole.
  • The R36 is a local access point that wirelessly repeats the desired signal to the house. In this way any wifi-enabled computer or tablet using any operating system can take advantage of the outdoor high-gain antenna. And, no software (driver or utility) need be installed on your computer or tablet.

Realtek 8187L chipset because they announced in late summer 2011 that they would discontinue further driver support for all new operating system versions.
Realtek is not willing to support future RT8187L driver updates for latest windows, mac and linux, but will continue to production of the chipset into the future.
Realtek 8187L chipset is an old model (though great one) dating back to 2006.  This chipset is the basis of Alfa AWUS036H authentic version.

Try these steps to narrow down the possible cause:
1. Try more than one device (try a USB mouse, for example, and at least one other USB device)
2. For USB extender or active USB cables:  Try using the auxiliary power supply
3.  Try more than 2 of the USB extender just in case 1 or 2 is defective
4.  Try more than one ethernet cable.  Try just a short Cat5e cable just to see if you can get it to work before moving on to longer lengths
Our sku of the USB extender is UE
