reset connection linksys router using script?

Hi all,

Once every so often, my linksys router loses the internet connection,
but fails to detect it:
The internal network still works.
Looking at the router status page, everything is reported as ok
but no traffic to/from internet is possible.

It can be solved by simply disconnecting and reconnecting using the
button on the router webpage. No power cycle is needed.

I suppose this behaviour is due to the internet ADSL-connection.
At another site, I have the same router but with cable internet. There,
the router never hangs, even after interchanging the routers as test.

I would like to have a script do the reconnection automatically:
every 5 minutes (cron) it would ping a external "always-on" site.
if the ping fails, the connection is to be reset.

the problem is I do not know how to translate the connection reset into
a script.

The source code behind the router status page disconnect button:

<input type=button value='Disconnect' onClick='pppoeAction
(this.form,2)'>

and

function pppoeAction(F,I){ F.pppoeAct.value = I; F.submit();}

any help is appreciated.

Check if you find something like "nailed up connection" or "persistent connection"
to turn on.

Have you tried ifconfig down followed by ifconfig up? Should
"recycle" your interfaces through the boot sequence. Easier to script
but has the same "problem" -- ie., interrupted connection via cron.
Maybe echo a warning/opt out before the recycle is started?

The PPPoE client resides on the router? Connecting via ethernet port?
Tried a wire trace with Ethereal near "drop" time? Does it reveal
any pre-drop traffic that would indicate a _network_ problem?

Googling:
linksys BEFW11S4 v4
returned 1100+ hits with only a few sales pages seen.

Sounds like this router does have its problems, but I would double
check for network problems at/from your provider -- many are
oversubscribing in an attempt to make some profits in this business
climate. Some have been accused of "auto-dropping" connections but
that doesn't sound like good business at all. But ...

there is an "keep-alive" option. But this does not work since the router
does not seem to detect the internet connection is out.

Unless I'm mistaken, ifconfig down/up would power down/up the adapter
card in the linux machine. As the router is a seperate box from the
linux machine, this would only reset the network connection between the
router and the linux pc. This connection is working: it is the internet
connection that's out.

the setup:
LAN WAN
linux pc <--1--> router <--1--> ADSL Modem <--2--> internet ISP

cables 1 = UTP cat5
cables 2 = phone cable -rj45

the router has four switched ports plus a wireless port on the LAN side.
two other pc's are connected by cable to it and one laptop goes
wireless.
All these machines can communicate amongst themselves but not to the
internet if the problem occurs.

the PPPoE client resides in the firmware of the router and is totally
seperate from the linux.
the linux does not have anything to do with making the internet
connection. It just see a regular lan connection.

I'll look into ethereal. As one of the pc (rather the user) downloads
moives and stuff, it's very possible the router has too many
simultaneaous connections and then decides to go for a coffee.

The purpose of that linux script would be to shorten the coffee break to
a few minutes :)

I'll check that out too.
