Is this what is called a "connection drop" ?

Hi !

I have 3 computers connected using a 2 weeks old D-Link DI-624 router.
For the moment, they are all connected using a cable, the wireless
functions are disabled.

Last time I used my network yesterday, everything was working fine.

This morning, I found MSN Messenger "waiting to reconnect" dancing icon
in my tray. On another computer, firing IE resulted on a "this page
cannot be displayed - DNS error" message.


I first went in my router's status to confirm that I was "connected".
A look in the log revealed nothing unusual.

I then checked with my ISP and was told that they had no problem to
report on their side.

I finally went in the router's tools tab and rebooted the modem. After
a few seconds, my internet connection was up and running again.


Is this what is called a "connection drop" ? It's the tird time in
the last two weeks that it happens. Is it a known problem with the
DI-624 ? For the last two years, I had a SMC-7004VBR and did not
experience this kind of problem.

Is there anything I can do to fix this ?

BTW, the router's firmware is version 2.53 (the latest)

Thanks..

I've been having this problem with the 2.50 firmware on the DI-624. I'd also
like to know what is happening.

Also, where did you get the 2.53 firmware? I can only find 2.50 listed for
Rev. C of the router.

The next time it happens, look at your lease start and expiration times
for your dynamically assigned IP address from your ISP's DHCP server.
Maybe the problem is when your IP lease expires and you are *supposed*
to get a new one. I've seen it where the IP lease expired and the user
was reverted to APIPA addressing (which allows connecting to other
intranetwork hosts but not out to internetwork hosts); see Microsoft's
KB articles 220874 and 307287 regarding APIPA. I had to logon the
router and force it to release and renew its WAN-side IP address (which
is the IP address to which traffic gets returned from requests that you
send out). As soon as I say "ipconfig /all" show up an APIPA address
(169.254.X.X) being used by my host, I knew the IP lease renewal didn't
work. My ISP could help and didn't know why the problem occurred, but
then they don't support a user's router behavior, anyway.

I think I had this problem show up about 3 or 4 times per year and I was
using a D-Link DI-604 at the time. I'm now using a Linksys BEFSR41 but
only had it a month so I won't know if the problem gets exhibited until
a lot longer time has passed. A Google search on "+APIPA +Linksys
+BEFSR41" shows some others have experienced the problem with the
Linksys, too. Obviously my IP leases are nowhere near that long so the
problem didn't occur on every IP lease expiration but only a few times.
What I did notice a couple times is that my ISP's DHCP server was
unresponsive, so an IP lease renew operation would timeout. So if the
request times out then I suppose you get reverted to APIPA so your
intranetwork remains functional.

Rebooting the modem probably triggered your router to successfully
perform an IP lease renewal. After all, the cable modem also has its
own DHCP server (and probably from which the router gets its WAN-side IP
address) and that was where I actually would see APIPA getting used;
i.e., my router would request an IP renew but it goes to the cable
modem's DHCP server which was unable to connect to my ISP's DHCP server
so the cable modem's DHCP server was reverting to APIPA. I don't know
which cable modem you are using, but I can login to my cable modem's web
server by browsing to http://192.168.100.1/. You could try
disconnecting the cable from your cable modem to see what LAN-side
Ethernet IP address it was using (after a reboot of it while
disconnected) and then do an IP renew at your router to see what
WAN-side IP address it got from the cable modem's DHCP server.

As far as I know there's an option "renew IP forever" or "auto-reconnect" in
the DI624, just to avoid loosing connection.
At least, there is such an option in the DI604 for dynamic IP, and several
options exist for PPPoE but since not using those I might be wrong here.

For firmware (European models):
Check ftp://ftp.dlink.de/di/di-624/driver_software/
Root for all firmwares for the DI series is ftp://ftp.dlink.de/di/
For DI624 rev C version 2.52b is listed.

Keep an eye on this thread, we never know ! :-)

Here: http://support.dlink.ca/ProductView.asp?ProdID=219

I suppose you looked in the corporate site (dlink.com) ? I know the
2.53 version isn't listed there, don't know why !

If you the firmware at the above link, keep in mind that the corporate
site states this below the firmware download link :

"This firmware is engineered for US products only. Using this
firmware on a device outside of the United States will void your
warranty and may render the device unusable."

One may expect that the reverse is true, that is a firmware designed
for Canadian products may not be suited for foreign products.

And while we're at it, I wonder to what extent this country based
difference in design really exists and why they simply don't use
different product numbers to designate products that are different. :/
Anybody has an idea on this ?

Are you talking about the WAN connection parameters or the DHCP lease
settings ?

If it's the WAN connection setting, it is currently at "Always on", and
as I stated in my original message, the router's status was "connected"
when the problem showed. (and it is PPPoE, by the way).

If it's the DHCP lease settings, unfortunately, mine has only the
following values allowed : 1, 2, 3 hours, 1, 2, 3 days, 1 week. The
current value is 1 week.

As I said in my answer to NoRemorse, I'm not sure wether or not I
should safely use an european model's firmware in a canadian unit.

Yes, but that option is only for DSL connections (where you configure
your router to use PPoE), not for broadband cable. I didn't see where
the OP mentioned whether his "modem" was for cable or DSL. The "cable"
the OP referred to was the Cat5 network cable that interconnected his
hosts to his router, not for the type of connection on the WAN-side of
his router. I assumed cable (and why I didn't think of the keep-alive
PPoE setting). The
http://www.smc.com/index.cfm?event=v...EN_USA&pid=924
is just the router (not a combined router and modem device) which
connects to either a cable or xDSL modem, so we don't know what type of
upstream connection the OP has to his modem.

After a refresh on the newsgroup posts, I see the OP is using PPoE (so
presumably is using aDSL) and says that the "always on" keep-alive
function in the router is enabled.

Vanguard a exprimé avec précision :

Thanks for your answer.

I just changed my lease time from 1 week to 1 day and post the results
tomorrow.

By the way, in case it may be significant, the DCHP is enabled, but all
my workstations are configured with a static DHCP address. The router
doesn't show the lease expiration time, but I can get the info at the
client level.

Just to avoid confusion : the router your link is referring to is my
previous router. The router I'm experiencing problems with is the
D-Link DI-624 ( http://www.dlink.ca/product.php?PID=151 )

As for my upstream connection, it is aDSL line (G-DMT standard),
2294up/542dn kbps.
