Vista - Internet connection suddenly halts every 24 hours

I'm presently experiencing a situation in which my Internet connection (cable
Internet) will suddenly and inexplicably come to a complete halt. This has
absolutely nothing to do with my actual cable Internet connection; everything
with the cable modem is functioning perfectly.

Instead, just about every 24 hours I will reach a point in which my desktop
system (Windows Vista Ultimate) will simply shut itself off from the Internet.

I have absolutely no idea what is causing this.

In the past, I have been able to go to the Network control panel and simply
perform a repair of my Internet connection. This no longer works.

However, restarting the system works 100% of the time.

So basically I'm left with a system that functions for approximately 24
hours, then it must be restarted in order for me to continue using the
Internet. Then of course the cycle repeats itself.

I'm not using any third party firewall software by the way, only Vista's
firewall.

I'm really getting tired of this!

Any ideas...?

Are you supposed to have a fixed IP address? If your IP address
changes, then this may be the cause.

If so, all you have to do is set the connection for auto-redial
on demand. The computer isn't actually dialing, but certain
Internet connections still work that way.

I may be totally wrong. It may be something different. Just
thought I should mention this.

According to the ISP representative with whom I just spoke, there is no
automatic shutdown of the Internet connection every 24 hours. There is no
automatic or regular shutdown at all, he said.

He said the only thing he knows of in association with Windows Vista is an
issue that is sometimes referred to as "time to live." He said to do some
research on this because it sometimes governs the amount of time Vista allows
for your Internet connection to be live; after that point it shuts down and
you have to restart.

He really didn't know much more about it than this.

If anyone has any ideas on this, please let me know. Of course I'm going to
be doing research in the meantime...

I think he's talking about DHCP IP Lease time. On my system it is set for
48 hours, for the Comcast Internet access address and for 24 hours on my LAN
router. (two sets of DHCP addresses). Most times the address doesn't
change but it could. There could also be a blip in network access. Take a
look at your router. If its a Linksys and it's set to "0" that means 24
hours. Others may be similar.

Hi Bob,

This is the router that I'm using; it's the one we've been using here in our
home office for the past three or four years.

http://support.dlink.com/products/vi...ctid=DI%2D704P

I'm assuming that there is the possibility that this router will have
problems with Windows Vista...?

I noticed on this support page that the Vista operating system is not
necessarily supported. Additionally, I cannot upgrade the firmware; no
firmware updates for Vista are available.

Maybe this is the underlying problem...?

I'm going to try to play around with some of the settings noted on one of
the associated tech pages; maybe this will prove useful.

Thanks!

UPDATE TO LAST POST:

I just discovered on D-Link's support website that our particular router
(DI-704P) is indeed compatible with Windows Vista.

We are not running the firmware software, as it is not required for this
router, by the way. So I'm unable to check on any of those settings that you
noted, Bob.

The one thing that was recommended on one of D-Link's support pages for this
router was to make sure that UPnP (Network Discovery) was disabled. This is
one step that I have taken -- it has now been turned off under the Networking
control panel.

If anyone has any additional ideas, please pass them along.

Thanks!

Here is the actual support webpage that shows that the DI-704P router is
compatible with Windows Vista, by the way:

Thanks again for any and all help!

in this case, compatible may mean very limited functionality. it is
a very old device in computer years.

The problem that I was encountering was that I was losing my Internet
connection about every 24 hours. Thankfully, this hasn't happened for the
first time in several months as a result of turning off Network Discovery.

I have exceeded the 24 hours (yesterday) without losing the Internet
connection.

We will see if I'm able to maintain the connection over the next 24 hours.
I'm certainly hoping so.

Thanks very much for all input!
