Version 1.1 uses the same TP-LINK firmware, see here.

The prescribed dd-wrt v24 preSP2 beta build 15778 for TP-Link WR740N v1.0 Firmware: Special image for initial flashing factory-to-ddwrt.bin 2010-12-13 3,75 MB works!

[edit] Limitation/Bugs

Like other 4mb flash devices, Web Admin GUI over HTTPS does not appear possible: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=323469

(If you do decide to test it in a recent build, I'd recommend leaving another management method enabled like SSH or HTTP...)

As of April 2020, none of the bugs below are present.

previously as of v4:

-LAN client cannot see each other (possibly fixed on latest build)

-No TX rate increase, hardware limit is 18dBm

-No 40Mhz channel (means no 150mbps advertised speed, capped to 20mhz which is at 72 Mbps)

[edit] How to install DD-WRT

  1. In TP-Link webinterface do a FACTORY RESET
  2. In TP-Link webinterface (now 192.168.1.1) upgrade firmware using

factory-to-ddwrt.bin from 740N folder. See Where do I download firmware? for links.

  1. Then log into dd-wrt (192.168.1.1).
  2. Set a login-name and password.
  3. Then upgrade (Administration > Firmware upgrade) using

tl-wr740n-webflash.bin
