I've figured out the sntp error.
sntp means simple network time protocol.
The 1810 says the date is dec 31, 1969
I enabled snmp, hoping to set the date on the 1810, and influence the firmware update, but no luck.
Disabling sntp makes the errno365 go away.
-------------------------------------------------------
I'm trying to upgrade the firmware on the 1810 from p.1.6 to p.1.17.
Using the web interface SW, Maintenance\Update_Manager, update_method=http, browse_for_file=p1.17.stk, update_type=code, image=backup, (press download)
pops-up a window that says Warning: The data transferwill take few minutes ...(click OK)
pops-up another window that says 1) make sure the image transfer was successful,... (press enter)
pops-up a Transfer_Status window, with progress indicators,
Then the web interface blinks, and I'm at the login screen.
But also sometimes, my laptop nic pops-up a window that says, network cable unplugged ( which is wrong) and the web interface says "The page cannot be displayed
The status\logfile is empty, no indication of a file transfer.
What do I do?
