When a DHCP client (dynamic IP address) receives an
address (and configuration) from a DHCP server a "lease
time" is part of the info.
The client is ALLOWED to use that address until the lease
expires.  If the ISP is re-initializing the cable modem, DHCP
server, or routers (some of these do filtering to keep out rogue
-- unpaid -- clients) before the lease expiration your client
won't "renew" automatically even though the IP is now useless.
This is WRONG of the ISP (their equipment.)  If this is it, it is
their fault.
They might ignore you or whatever but that would be my
diagnoses.
(DHCP clients renew at some percentage of lease expiration,
the amount isn't important, and on reboot typically OR when
you type that "IPConfig /renew")
If the ISP won't fix it -- sounds likely -- and the renew solves
it, then I would build some kinds of "background batch file"
that tests the line, and issues the renew if necessary."
I don't think Ping sets the errorlevel so you will have to find
another program to test the net from the batch.
You could just run a renew every 5 minutes or so, I suppose.
(It might irritate your ISP but they likely deserve it if you have
to work around this problem.)
