I flashed with this one, everything is 99% working, just WIFI speed is 72mb max.
I tried NG mixed 40mhz, N only 40 mhz, always with "clean" channel .. nothing worked.
How and can I get 150mbps. .. with DD-WRT?

I am using build 24160 and getting 105mbps speeds.
Use HT40(20+20) NG Mixed and will only work if channel is on auto.
Sorry, corrected my typo. Posting before I finished my first cup of coffee this morning. _________________ TP-Link TL-WR740N v4 (build 24160)

Because it keeps on working, don't make it right.
Though I have a thread created but wanna ask that after flashing the June and even the May release my WAN is not working.. I'm not able to connect to the internet even though my PPPoE connection is set...
Hey, sorry if these are dumb questions, but I'm pretty new to all this. I have dd-wrt set up on my wr740n, and I'm hoping to do a few things with it: Use it with privateinternetaccess as a VPN (so I can access netflix in Australia), use it as a wireless access point (separate from the modem/router), and use the router to plug into ethernet cables to connect my laptop. Is this possible?

Any help to downgrade or use webrevert will be highly appreciated.
I reverted from latest ddwrt firmware like this:
1. enabled ssh (in services tab)
2. enabled ssh administration (administration tab)
3. using winscp connected to router (root:[your password here]), copied ftp://tplink-forum.pl/orgin_bez_boot/wr740nv4_pl_3_16_5_up(130513).bin to /tmp and renamed to revert.bin
4. connected using putty to router (root:[your password here]), executed mtd -r write revert.bin linux
5. router rebooted and now uses original tplink firmware
stalingrad download link is broken.
Anique you can download ir from the FTP here ftp://tplink-forum.pl/orgin_bez_boot/ _________________ TP-Link: TL-WR741ND V4

it's not broken, you just have to select it with your mouse and paste the whole link in address bar, the forum have cut the link incorrectly

Really, all I tried to make openwrt work as repeater leads to topic "issue with ...." which leads to new bug topics.
I am not a linux programmer nor a system designer. I didn't know that I'd need so to just make it work as repeater.
*edit* I finally got openwrt running as repeater (using relayd). It was hard at first, a lot of reading...
-How to flash firmware over Bootloader-
Valid for TPLINK WR-703N and WR740N v4.
This is valid to flash any firmware you want, but also to recover from bad firmware flashing too!!
(If you didn't damage the bootloader itself, which is very strange to be flashed with common firmwares)
Tested firmwares are 740n v4, 703n,openwrt(choose "Factory" file, not "SysUpgrade"!), and DD-WRT (choose "factory-to-ddwrt" , don't use webflash version).
Things you'll need:
Quote:
Terminal(putty, teraterm, hyperterminal, that's your choice)
Tftpd32: http://tftpd32.jounin.net/
firmware (in .bin format)
Ethernet cable
Solder and soldering iron
Thin cable
Serial adapter
Sorry for the mistake. RX and TX are reversed!
If you can read the console but you can't write anything, and you are sure that the soldering is well done and the cable is working, then try this fix.
Once you got the serial, open a terminal with this settings:
Quote:
115.200 baud
8 bit data
1 bit stop
no parity
no flow control
Don't worry about Tx and Rx pins.
Obviously router's RX goes to computer's TX, and so on. But if you get them reversed you won't break anything.
If you don't see anything on console, maybe they are reversed, so try swapping them.
Power on the router and you will see the console booting up.
You will see
Quote:
Autobooting in 1 seconds
That means that the bootloader waits for you 1 second before continue loading.
So you must power on and type "tpl" as soon as you see anything in the console, to enter the command line.
Quote:
tpl
If sucess you will be in command prompt:

Now, connect an ethernet cable betweeen your computer and the router, any port will be ok but NOT WAN port.
Configure IP address in ethernet interface of computer as:
Copy "firmware_file.bin" file from into tftpd32's folder. (you can flash any compatible firmware, but in must be in .bin format!)
Now open TFTPF32.
Now, in the bootloader shell, type this and press enter:
Quote:
hornet> tftpboot 0x81000000 firmware_file.bin
(you have to put the same name as the file you copied in TFTPD32's folder)
Then you will see it downloading the file:
Quote:
eth1 link down
dup 1 speed 100
Using eth0 device
TFTP from server 192.168.1.100; our IP address is 192.168.1.111
Filename 'firmware_file.bin'.

done
Bytes transferred = 3932160 (3c0000 hex)
It should put "3c0000 hex" at the end , check it!!
Otherwise DO NOT continue, a bigger file may overwrite your router factory calibration data and you won't be able to recover them.
At this point, don't worry if it was a different size, the transferred data is stored in RAM, so you can retry with other file, or shutdown the router.
You're still in the safe area, nothing is deleted/flashed yet!
When finished type:
Quote:
hornet> erase 0x9f020000 +0x3c0000
(check twice when typing, this is dangerous, you can brick it if wrong numbers are typed, and there is no JTAG!! )
Now, it should have erased 60 flash sectors as this:
Quote:
First 0x2 last 0x3d sector size 0x10000
61
Erased 60 sectors
Now the last command:
Quote:
hornet> cp.b 0x81000000 0x9f020000 0x3c0000
This will copy the image you downloaded with tftpboot and saved to the RAM into the flash.
Again, type the correct numbers, or you will copy some ramdom data from the memory into flash, thus writing incorrect data, overwriting the factory calibration data or even corrupting the bootloader.
When finished, your router will be flashed and ready:
Quote:
Copy to Flash... write addr: 9f020000
done
Now power off the router, wait 2-3 seconds and power on again.
If you flashed the correct file you will have a working router.
Just for letting the people knowing:
I sucessfully flashed the WR703N firmware onto WR740N v4 with this method (to make it work as repeater while I was learning to setup openwrt ).
Firmware here:
Link to 703N firmware:
http://tplink.cn/downloadfilesuploadfolder/2012110162848.rar
(slow link due chinese server...but only 3.5MB, be patient)
Have fun!
Thank you I recovered my WR741NDV4 with this tutorial.

Hi guys!
I tried to debrick my wr740n with dabyd64's tutorial. Serial port soldering done, but when i want to connect via putty i get the attached characters.
com settings are correct:
115.200 baud
8 bit data
1 bit stop
no parity
no flow control
Did anyone see something like that?
Thank you in advance
