27506 is fine, I forgot to update my signature.

I recommend to update following these steps (use Firefox with cache cleared and an Ethernet cable):

1. Update from stock firmware to DD-WRT 21061, use factory-to-ddwrt.bin file from ftp://ftp.dd-wrt.com/betas/2013/03-25-2013-r21061/tplink_tl-wr740nv4/

2. Update from DD-WRT 21061 to 27506, use webflash file from ftp://ftp.dd-wrt.com/betas/2015/07-09-2015-r27506/tplink_tl-wr740nv4/

3. Reset to factory defaults

4. Set up the router manually.

Many thanks for your prompt reply!
I will follow the steps you said. I always use Firefox (on Lubuntu), but didn't know about step 1.

I will use this router as a Repeater Bridge for Wifi, as I have some weaker spots in the flat that I would like to cover.

BTW, is build 27506 still considered to be the most stable one?

EDIT: are there any limitations that this router will have with ddwrt or everything should work quite stable and fine?

Yes. No critical bugs known.

Works great for me.

Hi all,

I have a TL-WR740N v4 which has been thunderstrucked. The WAN and 2 LAN ports damaged, the other 2 LAN works.

I installed DD-WRT on the device, it is working fine. I tried to re-map the WAN port to a working LAN, but i have no success.

I used
Code:
nvram set vlan0ports="1 2 3 5*"
nvram set vlan1ports="0 4 5"
nvram commit
reboot

from http://www.dd-wrt.com/wiki/index.php/Switched_Ports , but i don't know which port number is referring to which physical socket.

Can anyone help me to re-map the WAN? Or only with ht physical port numbering?
And the other thing, will the re-mapped WAN act as the original?


Thanks in advance Smile

Hi,

We use a lot of TL-WR740N v4, TL-WR740N v5, and TL-WR740ND v5 with our customers. These are all loaded with v23919. Lately, we're seeing more following situation happening..

1. WIFI stop working and stop broadcasting. Ethernet continue to work fine. A reboot is required.

2. NVRAM setting becomes corrupted. Setting such as SSID change to "ddwrt", etc. Any attempt to change setting would cause router to reboot. Only way is to recover to stock (through tplink build-in recovery method), and reflash to ddwrt again.

What would cause these prbolems? Any feedback is much apprecaited.

Builds before 25974 have the ath9k WiFi dropout/freezing bug, see ticket http://svn.dd-wrt.com/ticket/2952
You can check out the ath9k fixes in the changelog http://www.dd-wrt.com/phpBB2/viewtopic.php?t=279466

I suggest installing 27506, which run relatively stable for months on my Atheros-based routers. If not, latest build 28112 would also be a good candidate, but not much testing has been done since it was just released yesterday.

KrypteX,

Thanks for the reply, I will try 27506.

Do you have any idea what would cause NVRAM to go corrupted?

According to http://dd-wrt.com/site/support/router-database , the first step to flash from Stock firmware to DD-WRT is:
Build 21061, file "factory-to-ddwrt.bin" from ftp://ftp.dd-wrt.com/betas/2013/03-25-2013-r21061/tplink_tl-wr740nv4/



Hi,

I always wonder which factory-2-ddwrt to use. Since 27506 provides factory-2-ddwrt file, isn't it easier to just use it to one step upgrade to 27506?

Hi, has anyone tried to downgrade to an older version? If so, how could I do it safely?

I have installed the 27858 build but its been very unstable and I want to use the 27506 build as I have seen here its the most stable one at the moment.

Simply flash this file ftp://ftp.dd-wrt.com/betas/2015/07-09-2015-r27506/tplink_tl-wr740nv4/tl-wr740nv4-webflash.bin
Don't forget to reset the router AFTER you flash it (but wait 2-3 minutes before doing so) and don't restore your settings. Set it up manually.

I guess you meant WR740N. Latest 28444 runs OK on it.
