I bought TR-WR740N, made by TP – LINK, router and also function as Wireless Access Point to extend my existing access point range which managed by TR-WR340G. I was trying to connect them up or in correct term named bridge. I found none from google explains this up so maybe quite fine to writing about it in this site.
I was almost pulling my hair connecting these two router even in same brand. I want TR-WR740N will be my main router replacing the old WR340G but I face problem to unclear firmware update from TP-Link it self, if you trying to download WR340G firmware you’ll found several firmware for different hardware version and I don’t even know what the correct version of the hardware. It’s say V2.24 but there’s no firmware for v2.24 hardware, how confusing it was. So, I download firmware for V2 hardware since 2 is the major number from versioning and guess what happen next, in the router’s web interface I can see the hardware version overwritten to version 3. Dear God.
Now, I am going to connect this two wierd device into bridging mode. Now, connect your WR740G to your computer using LAN cable and accessing it’s web interface, go to Wireless Setting and active Enable WDS. You’ll find this screen
Press on Search button, you will see how many router / WAP around you including your neighbor router. Find unused channel, and make it as your Wireless channel to your home, in Indonesia radio interference is high so I need to find the most quiet channel. Please follow your country regulation to this setting.
In my test, WR340G can’t connect your WR740G. Why? because WR340G reads WR740G MAC address wrongly and the bridge function in WR340G is crippled. For example, 11-22-33-44-58 it reads 11-22-33-44-5F. How on earth that two router could communicate?
Second reason, WR340G only able to handle one Wireless encryption at one time. One for user, one for wireless bridge. So this is the finalization to frustration because I won’t my wife using WEP encryption when connection her mobile phone to WiFi .
Now to solve that problem, this is my final configuration; WR340G will be my router and connected to WAN, in my case connected to Cable ISP, and then WR740G will act as Wireless Access Point which shown in this following simple diagram. It’s very simple to implement but I have difficulty to figure it out how this two thing could connect each other at first.
Make sure your WAP didn’t use the same name if you don’t want your user confuse which one to connect. I have no problem to this because WR740G could handle different encryption to wireless bridging and wireless connection (end user). Hopes will work to you too.
