Hi,
The experience with PPPOE and DSL connections is varied. Some people claim
to have virtually endless days of having no disconnects. Others are not so
lucky. As part of the PPPOE protocol, there is a "Ping-like" option (LCP
Keep Alive packets) that allows the host software or firmware to send KEEP
ALIVE messages to the ISP in order to keep the connect alive, and if not
alive, to get it back to a connect state again. The problem could be due to
many reasons. DSL is not as robust as Ethernet to a PC or Mac users, when
implementing and living with it on a daily basis.
There are quite a few Routers that supports only a Idle Connect Timeout,
which tries to sign back on if the timer value is set to ZERO. This is
different from the KEEP ALIVE feature, which is more aggressive in keeping
the remote side busy in maintaining the connect status. Since documentation
on Routers is not clear on many of these issues, maybe KEEP ALIVES are
buried into the firmware, of some Routers, which has no exposure to a user
through a configuration setting. I wish I knew the details of each make and
model. I think its something that rarely gets documented. I've seen no web
site that doocuments the various Routers.
For example, I know that Linksys has some models that support KEEP ALIVE in
the firmware setup. The Dlink 714P+ has it in their firmware config screen.
I checked a couple Netgear Routers, the FM114P and the MR814, and they do
not appear to have a setting for KEEP ALIVE packets. What other makes and
models have this option in their firmware? Either exposed through a user
setting, or buried in the firmware?
Thanks,
