WNHDE111 emergency recovery needed
Hello, I have a AP/Bridge WNHDE111 that is blinking once per second (corrupted firmware sign). It does not response on any buttons or network connections. Prior to becoming a paperweight, it freque...
I was able to flush the firmware on WNHDE111 as follows:
(Beforehand, download the latest firmware *.bin file from the Netgear WNHDE111 page)
1. Connect the AP/Bridge in AP mode directly to a PC.
2. Turn it on.
3. Wait about a minute, until Windows stopped complaining about unplugged network cable.
4. Open Start->Run->cmd, then type ipconfig at the C: prompt.
5. Computer shows that Ethernet card has IP 192.168.0.x, Default Gateway is 192.168.0.100.
6. Ping 192.168.0.100, make sure that it returns all 4 pings.
7. Start browser, type http://192.168.0.100
8. WNHDE111 displays a emergency recovery page asking for the firmware file.
9. Point it to the downloaded file, wait 90 sec, and - voila - problem solved.
10. Windows will start to complain about unplugged cable again, but it is expected because AP/bridge has DHCP server disabled in normal mode. As a result, Windows will assign 169.254.x.x address to ethernet card, which will make WNHDE111 invisible for it (its IP is 192.168.0.240 default).
This procedure is not documented anywhere as far as I can tell.
I don't know if this is a universal procedure for Netgear devices, or one specific for the AP/bridge.
