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
- In TP-Link webinterface do a FACTORY RESET
- 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.
- Then log into dd-wrt (192.168.1.1).
- Set a login-name and password.
- Then upgrade (Administration > Firmware upgrade) using
tl-wr740n-webflash.bin
NOTE: Build 33555 (10/20/17) that patches the KRACK vulnerability in WPA2 runs on this router, it can be downloaded here [1] - Tmittelstaedt 10/21/2017
