Hi kernel-panic69,

I know about problem with this router model to not work Ethernet LAN Port 02 of any version DD-WRT.

I know about any step how to firmware from official downgrade and install DD-WRT.

The problem is after update to last firmware version 44715 and get successful update message on webpage. After that router not work, not access nothing only go up and after reboot and that is all.

I can ping ping 192.168.1.1 -t and get

Well, you didn't completely brick it. You should be able to either go into management mode (if available) and flash back to stock and try again or use tftp to recover from a bad flash.

I would try flashing the last known good working build for the router, if you're going to use a DD-WRT image.

Hello,

After so many solutions to fix this problem, finally i fix and back router in live.

I moment what i don't know is a TFTP IP request from router E1700 side. To know that i use wireshark and sniff and on that way i found this.

TFTP Recovery
E1700 IP 192.168.1.1
TFTP IP 192.168.1.100
Filename um_factory_fw.bin

The TFTP applications who is help me to see logs and be my tftp server is tftpd

For file um_factory_fw.bin i use version of DD-WRT one before last, and back on stable version.

After re-flesh on last version 44715 i see to this version not support wireless and for that i back on 40559 where everything work fine.

Thank you for suggestions and help @kernel-panic69

Take care anyone and Cheers! Smile

If you're going to stay stuck using the router database, you will fall behind on security patches and other stability updates. I really wish people would flash and report on supported devices in the build release threads.
