Newly I noticed that my RT-N66 has troubles with WAN link.
My config is VDSL Technicolor FTTC Modem\Router acting as pure modem --> RT-N66 for routing and WAN connection. If I don't look at the log everything seem to work well.

This is the Log
Code:

Can anyone help me understand what's wrong with my config?

Ps. Before 378.56 I didn't notice this kind of message but I'm not sure that there was.
 
PADO timeouts are usually caused by something upstream of the router....

- try replacing the ethernet cable between the router and modem
- if you can get to the modem logs, check those for a problem reported there
 
- try replacing the ethernet cable between the router and modem
A good CAT5e or CAT6 cable needed - the N66U is very sensitive about cables... :rolleyes:
 
Thanks to both of you. First of all I'm going to buy a brand new Cat6 Ethernet Cable. Then I logged in the modem GUI searching for something like a LOG but without luck, btw i noticed that due to remote handling of my ISP over his modem some setting was restored to default and one is the AutoConnection that must be setted off in order to bridge the modem. I'll keep an eye to check if this is the solution and report back to you.

Thx!
 
Hey,
Stable (all): 378.56_2
Date: 3-Nov-2015
Is it really for all?
Because 378.56 was not suitable for N66U.
 
I have a month of uptime on my N66R with zero issues on this firmware.
