Hello,

My modem 7800DXL network crash randomly, it can work good 4 hours, or 2 days or 6 days max, then it crash:
- no wifi
- no ethernet
the wifi/ethernet del are green... but it don't work
DSL and internet green too
I can't access to the interface http://192.168.1.254/ when it crash, and no internet...
my lan network is ok, I can access to my other computer
I must reboot the modem to solve when I have this bug/crash

in system log:

Code: Select all

...

Jan 22 09:29:25 daemon info syslog: dhcp6c restart..
the security log is empty

my SNR is good (snmp/cacti), no drop:

firmware:
To try to solve it, I try to use all the firmware :
http://www.billion.uk.com/esupport/inde ... /Index/101
and
http://au.billion.com/products/wireless ... 00dxl.html
Actually, I'm with the etec7800dxl_2.32d_da1.afw which is the more stable (6 days max)
But same, all firmware have the same problem/bug.

the "Factory Default Settings" has been done always when I try to flash another firmware... don't solve
=> 4 hours until 6 days and the modem will crash

Can it be a bad setting ?
Can you help me ?

Thank you for your help
