Internet connection problems

[Guest]

I'm having some major issues with Vista 64 and internet connection problems.

Everything will work fine, then all of a sudden I cannot connect to the
internet. Comes up saying that the DNS is not found, and to contact my ISP.
I am using a speedstream 6520 router/modem, and I can connect to the modem
fine, it says I'm connected to the internet, yet I cannot sign into
messenger, or view any webpages.

I can mess around for an hour trying to get it to work, then all of a
sudden, I am able to connect again. My ISP has checked the lines and
everything is good. I've never had an internet connection problem with XP.

Any suggestions? I have all my drivers up to date, and have very new and
trusted hardware installed.

Specs:

DFI Lanparty UT nforce 4 board (newest drivers installed)
8800 GTS
Opteron 165
Speedstream 6520 modem/router (Bell sympatico)
Vista Home Premium 64 bit

This is very similar to what I am facing.
Internet works, but intermittently say 30 min or an hour, it would just go
down. I am using Motorolla cable modem and vista business.

Can you check your windows event logs (system logs). Is there a log like
dhcp-client started everytime connection drops?
I notice that everytime although there is evidence of that service crashing
otherwise.

There are incompatabilities with Vista and some of the built-in DHCP servers
in routers. As a result, kiss off automatic assignment of network settings
for these routers (wireless or otherwise).

You will have to MANUALLY set your IP info, just like in the old days.
Unfortunately, that also means that you will have to CAN those adapter IP
setting when using true DHCP enabled routers that actually work. When you
run into this, I've found that the alternate IP info does not work at all, it
never gets referenced or determined.

Here is one solution that may work for SOME routers (but it does NOT work
for all of them!)

The reality is that as long as you can connect to the router (i.e. local
only connection) then the manual assignment of the IP info should get you
there. And forget about wasting your time trying to use the Alternate
configuration, it doesn't work.

I dont see really anything for the DHCP... just a lot of errors about stuff
trying to access the net, but cant. It gets really frustrating cause I'll be
doing my normal thing on the net, and it will just quit.... and no telling on
when it comes back up.

Thanks for the link, but I'm not trying to do a wireless connection. I have
tried manually imputting my IP addresses, and turned off DHCP on the router
and in windows, yet the internet connection still drops while surfing the
net. My router/modem says I'm connected, but every webpage comes back as not
found. The only way I can get it to work again is by shutting off my comp
and router and restarting both.

I have had a similar problem happen to me. My router will hang/lock when the
MS Vista installed PC is switched on. Only after switching the router off and
on again, the router will function normally again until the MS Vista PC is
restarted again.

Does this problem occur due to the newly implemented IPv6 protocol? Also it
is impossible in my Vista to disable IPv6 even tho it is almost nothing that
use it.
So it is impossible for me to test manually.

An option is of course to buy a new router, but it would be interesting to
know why this happens. Buying a new one might not help.
