Alfa R36: Using with your DSL modem: Use R36’s Bridge mode

Mar 312013
 

The R36 DSL mode wanted to deal with authentication and IP which is already done by the DSL modem. The R36’s Bridge mode is the solution.  How to setup the R36 in bridge mode:

  1. Power up the R36 with Ethernet and USB ports not connected to anything.
  2. Power up your laptop. Make sure the built in wifi is NOT connected to anything and your ethernet port is NOT connected to anything.
  3. Connect an Ethernet cable between the R36 LAN port and your computer’s Ethernet port.
  4. Open your browser and type in the RJ36 IP address (192.168.2.1).
  5. When the R36 setup page shows up:
  6. Click on Easy Setup.
  7. Click on Bridge
  8. Change the SSID name from ALFA-AP to the name of your choice.
  9. If desired, set up a password.
  10. Click Done and wait for the changes to take effect.
  11. Remove the Ethernet cable from the R36 and your computer.
  12. Connect an Ethernet cable from one of the DSL modem Ethernet ports to the R36 WAN port.  The R36 LAN and USB ports will now have nothing connected to them.
  13. The R36 is now ready to use in Bridge mode.
  14. Using your computer’s wifi, connect to the R36 signal.
  15. Verify you are connected to the Internet.

NOTE in this mode you will no longer be able to access the R36 status page via your browser.  You cannot even access the page through Ethernet to the R36 LAN port!!!

The only way you can now access the R36 is by activating the reset button on the bottom of the R36 and then starting the setup all over again!

NOTES:  DSL modems (from your DSL provider) take care of user and password authentication and IP address assignment by DHCP from your DSL/internet provider.  DSL modems often have an included Ethernet bridge of four RJ-45 outputs (for example, the ZOOM modem from AT&T).

In bridge mode, the R36 is like an AP on the same subnet as the DSL modem’s LAN ports.

Alfa R36 boot-up takes 1 minute

Mar 312013
 

When you reboot it (unplug it and then reapply power), it takes the R36 about a minute to boot up before it is ready to use.

Be patient and don’t try to work on it during this one minute period.

Canada: Shipping & Payment for Customers in Canada

Mar 202013
 
  • Very small packages we ship by mail to Canada.
  • Any order over $75 in value, we must to ship by UPS:  Our UPS fees to Canada for the actual shipping, are very low:  HOWEVER:
    •  All UPS shipments into Canada involve a UPS customs & tax fee of approximately $42 to $47 (for orders less than $200) that will be the customer’s responsibility.
    • Larger shipments into Canada may have a fee of much more than $47 because the fee includes GST.
    • Shipments to Canada are required to be paid by PayPal unless/until we have a history of doing business with you

Notes from our customers in Canada:

  • For a purchase of $143.79 which included UPS ground mail of $26.78 I had to pay a further $53. 25 to UPS on account of customs and brokerage. He said (UPS) that if it had gone ordinary US postal and had been under $100 it may have gone through without all these additional charges.  The total cost was a surprise and I though you might like to know (May 2013)
  • Charges by UPS are very inconsistent.  Generally when the goods are worth < CAN$50 UPS charges nothing beyond the basic transportation costs, and above CAN$100 Canadian customs nearly always charges taxes (GST/PST) – and UPS charges anywhere from $30 to $70 import duties depending on the cost of the goods.  Between $50 and $100 it’s a crap shoot!  But I got a delivery in this week from my company worth US$670 via UPS; UPS didn’t charge import fees, and Canadian customs didn’t add any taxes – in fact, I think it was automatically released by customs before it ever arrived in Canada.  Maybe that’s because the items were being imported by my company and it was obvious that they were for resale.

Alfa R36: Tips for Optimizing / Power of R36

Mar 162013
 
  1.  Occasionally the R36 will “hang up” and not function.  Remedy: Remove power from the R36 for 15 seconds and then reapply  power.  The R36 will then resume normal operation.
  2. IP address conflicts may occur when too many devices start their DHCP assignments at the same place.  You can control this in the R36 by accessing the R36 at 192.168.2.1, then clicking on “Advanced”, then clicking on “LAN”.  DHCP settings are provided in the second section on that page, and begin at 192.168.2.100 and end at 192.168.2.199 by default.  Change the start point from 192.168.2.100 to 192.168.2.133 – it seems to help.
  3.  Any 802.11 transmitter may have a stated bandwidth of 20 MHz but this is only the 3 dB or half-power bandwidth. The actual spectrum extends much further than that.  Because of this, WiFI adapters and routers, including the R36, should be physically separated and/or shielded from each other for best results:  If possible, put one device on channel 1 and the other on channel 11 as a starting point.  Then use physical separation and antenna patterns to minimize interference between devices. The interference will show up as a reduced connection speed from what could be done before the R36 was added to the system. Operating the LAN (R36 to user computer) at 11 mbps
  4. (802.11b) seems to help also

WPS is a type of WiFi security called WiFi Protected Setup

R36 POWER

The R36 comes with a 12-volt AC/DC adapter with a standard DC barrel connector.

The R36 requires 12 volts DC at up to 1 ampere. The center pin on the R36 power connector is positive, the sleeve is negative. The wire with the white stripe from the R36  power supply is positive. The R36 supplies 5 volts DC to the wifi adapter via the USB cable.

Ubiquiti legacy products: Great low-cost alternative to AirMAX by upgrading firmware

Mar 072013
 

First-generation Ubiquiti products such as NanoStation2 & NS5, Loco2 & Loco5 , Bullet2, Bullet2HP are a great alternative to AirMAX CPE at a significantly lower price.

By upgrading your legacy Ubiquiti products to V.4 firmware, you will have compatibility and benefits of AirMAX protocol.  Be sure to have your APs using AirMAX firmware V.5.5 or a newer version.

R36 will not control the AWUS036H output power | Signal Amplifier usage w/ R36

Mar 032013
 
The AWUS036H connected to the R36 auto-adjusts output power by connection quality.
The R36 shows a number from 1 to 100 in the setup screens:  This number does not refer to the AWUS036H power output – rather it is for the R36’s radio.  This means that there is no way for the user to control power output from the AWUS036H — it is adjusted up and down by the firmware to suit conditions.
Therefore, a power amplifier could not safely be added to increase range.  (However, an input amplifier could be added to increase receive sensitivity.)
