Just to be sure, does the DMX LED goes off? I assume it's blinking as 
usual, but you can't ping the box anymore.

Yes, me too. It could be very complicated, but I am also very curious 
what is causing this. In order to exclude some possible ethernet 
switch oddities; please turn off any UDP broadcasting.

If you have a Mac or PC connected to the USB port as well, you can do 
some diagnostics with a terminal program (zTerm on OSX, or Hyperterm 
on XP).

Connect via the terminal program with the box via USB and type #*b7# 
<enter>. You should see ok. Now type mon" ping 192.168.1.1 <enter>. 
You should see answers like:

sent # 1 , PING receipt # 1 : response time 0.62 ms
sent # 2 , PING receipt # 2 : response time 2.12 ms
sent # 3 , PING receipt # 3 : response time 2.04 ms
sent # 4 , PING receipt # 4 : response time 2.43 ms

Sent        : 4
Received    : 4
Success     : 100
Average RTT : 1.80 ms
ok

Note: Be sure you type *b7#<enter> before disconnecting the USB 
terminal connection, else you can't connect it with LCedit+


If your gateway (the D-link) is on another address then 192.168.1.1 
use the D-link address.


If you got no response, try to place a simple hub between the D-link 
and the LCX.

For more tests I need to know the D-link type number, and your exact 
setup, inluding IPs, switches, etc.

If someone on the list has experience with D-link routers please let 
us know. We are using here Zyxel routers/modems, and have never had 
any problems.
