Video guide- how to update Alfa R36 firmware

Now available is our video guide showing you step by step instructions for updating or changing the firmware version of your Alfa R36 router. Generally if your R36 router is working fine then you do not need to update the firmware. But if you need to change what adapters is supports (for example you own an R36 router used with your old AWUS036H adapter and you just bought the new AWUS036NHV and want to make your R36 compatible) then a firmware update could be necessary.

How to optimize your Alfa R36 router

If you own an Alfa R36 router, you probably appreciate the fact that you can receive a long range WiFi signal and share it as a new hotspot around your home, boat, or any other place you may use it.

You can also optimize your R36 for best results. At its heart, the Alfa R36 is a repeater- but with a major advantage. You can use it with a compatible Alfa AWUS036H (or AWUS036NH or AWUS036NHR if you have the R36 NH/NHR version) to pull in a distant WiFi signal and repeat it so that other devices like iPads and laptops can use the new signal. Like regular repeaters, the R36 contains an access point to broadcast the new hotspot, and this can be configured.

We are going to cover three areas of configuration in this article, numbered on the photo below.  To change these settings, log in to your R36 using an Ethernet cable, and click the Advanced tab. Under Wireless Settings, select 'Basic'.


1. Network Mode

The default network mode is 11/b/g/n mixed mode. This allows any standard WiFi device to connect to your hotspot, whether it’s 802.11b, 802.1g, or 802.11n. This maximizes compatibility but limits the performance of your network if only newer standard WiFi devices will be connecting to the hotspot. For example, if you have only 802.11n standard WiFi devices (most modern laptops come equipped with built-in 802.11n WiFi adapters, however early generation iPhones have 802.11g WiFi receivers), you can change this to 11n only. This optimizes the performance of your new hotspot for 802.11n devices, but blocks backward compatibility with 802.11b/g devices. If you change to 11n only, we recommend writing a note and taping it to the top of the R36 for future reference. If you forget you have made this change and have a visitor come over one day with just an 802.11g equipped laptop, they will not be able to connect. Once you have changed the network mode, click Apply at the bottom to save changes.

2. Channel

Routers in North America have 11 channels. Every WiFi access point/router sends out its signal on one of these channels. If you have more than one WiFi signal nearby being broadcast on the same channel, this is known as channel crowding. This reduces performance on the network. Because most router manufacturers use default channels of 1, 6, and 11, chances are that there will be several signals around you on the same channel (if you are in a city area where you can see 20+ networks, channel crowding can be a major problem). To prevent channel crowding, click the channel menu and change the channel to as different one not likely to be a router default. Be sure to click Apply at the bottom when finished.

3. Channel Bandwidth

At the bottom of the 'Basic' settings screen, there are two options for channel bandwidth- 20 and 20/40. The default is 20. If you are experiencing slower speeds, switch it to 20/40 to see if this improves your speed. Click Apply at the bottom to save changes.

4. Placement of equipment

When using the R36 in conjunction with an Alfa USB adapter, try to put the USB adapter as far away from the R36 as the USB cable allows, and, if possible, several feet higher. Having the Alfa USB receiving antenna on a different horizontal level than the R36 transmitting antenna helps reduce immediate radio interference between the two devices. Having your Alfa USB adapter higher in the air will often allow it to receive signal more clearly and over a greater distance.

All of these things may be useful in optimizing or troubleshooting your R36 router.

Alfa R36 for AWUS036NH and AWUS036NHR now available

We now have Alfa R36 for AWUS036NH and AWUS036NHR in stock. This is the new version that does not support AWUS036H. We also carry the AWUS036H version here.

R36 is a unique WiFi router from Alfa Network, Inc. which allows you to share a WiFi connection from your AWUS036NH or AWUS036NHR WiFi USB adapter. It is the only router on the market that allows the input to be a USB WiFi adapter (the USB WiFi adapter must be Alfa brand, and must be one of the compatible models listed). Using its repeater mode, you can receive a long range WiFi signal on the R36 and share it with other WiFi enabled devices like tablets, game consoles, and other computers.

Now available- Alfa R36 USB-enabled Wi-Fi router for use with AWUS036H

This may just be the coolest product ever made by Alfa Network. Have you ever wanted to pick up a Wi-Fi signal from far away? Well of course, who hasn't. And Alfa has their AWUS036H 1000mW USB adapter for that very purpose. But have you ever wanted to have all of your Wi-Fi capable devices- like your iPhone, iPad, wireless printer, TiVo DVR, and laptop- all connect to a Wi-Fi signal far away? Perhaps you're living in an off-campus apartment and you already own an AWUS036H from Alfa. That lets your laptop easily pick up the campus Wi-Fi network, but it doesn't do any good for those other devices, putting you in quite a fix.

Exit fix, enter R36. The R36 is a new USB-enabled wireless router from Alfa Network, Inc. that allows you to attach your AWUS036H Wi-Fi adapter from Alfa directly to the router itself. Then you can scan for and connect to far-away networks using the admin utility built into the R36. This creates a new local Wi-Fi signal right in your room so all of your Wi-Fi capable devices can pick it up. Think of the R36 as a normal Wi-Fi router, but instead of using a cable or broadband DSL modem as the Internet source, it uses the Wi-Fi signal detected by the AWUS036H as the Internet signal. The R36 then repeats this signal around you as a new signal. The base package does not include an AWUS036H Wi-Fi receiver, but we do have this special kit that includes both.

Alfa's R36 can also be used with Alfa receiver models AWUS036EW and Tube-U(G).
