Feel free do download the photos to your server. I took them and they are free to copy. Email me User:Y23 if tinypic biffed them
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!
as of v4:
-LAN client cannot see each other (possibly fixed on latest build)
-No TX rate increase
-No 40Mhz channel (means no 150mbps advertised speex, capped to 20mhz which is at 72 Mbps)
In TP-Link webinterface I did FACTORY RESET
In TP-Link webinterface (now 192.168.1.1) I upgraded firmware to factory-to-ddwrt.bin
then I was able to log into dd-wrt (192.168.1.1). I have to set a login-name and password.
Then I upgraded (Administration > Firmware upgrade) to tl-wr740n-webflash.bin
BUT ALAS .... with Firefox it DID NOT WORK.
So I used IE6 and voila! bingo! Danke BrainSlayer! AWESOME JOB! I am stoked!
