...tried out DD-WRT build 14929 and 15506 but both were really unstable.
I'm new to this.
Bought a cheap (and chearfull) TL-WR741ND to play around. I managed to install the dd-wrt firmware, but after about 20 minutes the wireless radio started to work intermitently. This problem renders the device unusable I'm afraid, as the the wifi network desapears.
After a while it comes back, but only for about 10 seconds or so until it drops again.
1) I successfully flashed with factory-to-ddwrt.bin via Web UI.
2) I didn't find Openvpn I need.
3) I flashed with WEB UI dd-wrt.v24-15280_NEWD_openvpn_jffs_small.bin (http://www.dd-wrt.com/dd-wrtv2/downloads/others/eko/V24_TNG/svn15280/dd-wrt.v24-15280_NEWD_openvpn_jffs_small.bin) and bricked my router. It doesn't reply to pings and doesn't send any information (I Wiresharked).
Which build should I use to have Openvpn?
Information on a site is in a mess. Installation instructions unclear but according to information for BROADCOM devices at peacock thread NEWD flash can be used on a wide range of devices.
What I did wrong?
TL-WR741ND ver 1.9. Bought today. Bricked today:)
Try turning up power with reset button pressed
wait 30sec. and then release the reset button. Then try to access 192.168.1.1 with web browser or via tftp. I don't know if it will work on that router but it works on d-link.
Thre was another method 30/30/30 or 30/60/30 sec
you should investigate forum. There is a chance for your router to work without flashing with jtag.
WARNING: You may be unable to access even if you see fancy fast flashing of "SYS" LED due to a bug #6922
Unplug the router's power cord
Connect any router LAN port directly to your PC
Configure your PC with a static IP address: 192.168.1.2
Plug the power on to the router
Wait until the "SYS" LED starts flashing repeatedly
Press the "QSS" button (on the front of the router) – the "SYS" LED will now start flashing at a faster rate
Login to the router by using telnet to connect to the IP address 192.168.1.1 – there will be an immediate unauthenticated login to a root shell
mount_root - will mount the normal root filesystem
firstboot - all settings will be reset
/rom/sbin/reboot - will reboot even without a mounted filesystem
