Vista - internet stops loading pages, thinking dns prob

windows vista 32bit
intel core2 duo 6600
2gig ram
netgear wireless wg311v3


i can be using the internet fine and then sometimes a webpage wont load
so i tried the run "cmd" ipconfig/flushdns
and sometimes that fixes it for a little while then it stops working again
so i do it again and then sometimes it doesnt fix it

all other computers conected on the network work fine and there using xp

i can still use
messenger,
xfire,
p2p apps ect,
play counterstrike
IF they are connected b4 the problem occurs, if not connected they wont
connect

so some of these i didnt need to try but have just 4 piece of mind
ive reset the router
tried different browsers ie7 and mozzilla firefox
reset the wireless addapter
tried the windows vista diagnostic thing in ie7 and tried all the repair
options
and nothing has worked

the only thing that fixes it is resetting the computer

Bert02,

I'm sorry you're experiencing trouble. Is this still happening? If so then
this may be an issue with your router. Differences in the networking
stack between XP and Vista have exposed a lot of router bugs which were
hitherto hidden.

Vista uses UPnP much more heavily than XP ever did, and we've found that a
lot of routers have suboptimal UPnP implementations, causing them to crash.

1. Does this happen on both a wired connection to the router AND a wireless
connection?

2. when Vista "loses" connection, does it come back automatically, or do you
have to reboot your router? Do the other xp machines also lose
connectivity?

3. If ONLY the vista machine loses connectivity, then there is an issue with
your vista machine. Make sure your drivers are all up to date. If
wireless, make sure you have the latest drivers for your card. Go to
linksys' website and verifiy that what you've got is the latest.

4. While you're there, make sure you have the latest firmware for your
router. We found a lot of bugs in router firmware during development, and
the vendors posted a lot of firmware updates.

5. Then, try running the router tool at
http://www.microsoft.com/windows/usi...d/default.mspx, and see if it
passes the tests.

If we can narrow the issue down to your router, that is, that when Vista
loses connectivity ALL the machines (xp too) lose connectivity, then there
are some things worth trying:

A possible solution worth trying is to turn of UPnP. This can be done on
the router (you would have to log onto the routers config page, find out
where it has the UPnP on/off switch, and turn it off) or from the machine
itself.

You can also try disabling window scaling.

So, please try these out:

1. Go to the webtool, and when the test is finished, click on the "view
detailed report" link, and copy that data off & save it.
2. turn off UPnP, either on the router or on the vista machine:
from an elevated command prompt,type the following:
a. sc config SSDPSRV start= disabled
b. net stop ssdpsrv <or> reboot the system
3. Try your test again. If it still fails after some perioed of time, turn
off Window Scaling:
From an elevated command prompt, type the following:
a. netsh in tcp set gl auto=di
<no reboot required>

Same here (Vista Business 32Bit), I'm in a corporate network and a domain member. The router is a NetScreen 5GT.

All of a sudden, all but one applications are no longer able to resolve any host name (Firefox, IE, Subversion, etc.). I can't even ping the host name. The only exception is "nslookup". It's still able to lookup the host name.

Unfortunately, "ipconfig /flushdns" doesn't help. I have to deactivate/reactivate the network connection.

Same Problem

Network looks like this:


Cable Modem > Router:

MAchine 1: Laptop XP: Works fine no problems
MAchine 2: Laptop Vista: Has the Problem
MAchine 3: Internet Connection Sharing from Vista Laptop

-------------------------------------------------

Randomly ill be browsing websites on machine 2, BAM! "Internet Explorer Cannot Display the Page" i check fire fox.... "Unable to Connect" .... ok my AIM , MSN, YAHOO , TeamSpeak..... ALL WORK!. Now if i log off i an unable to log back on to these.

Now what gets me is Machine 3 is connected to Machine 2 and works fine.... (i was to lazy to get a wireless adapter for it)

So ill click "Diagonose Problem"

Result: "Windoes confirmed this computer cannot connect to www.google.com The Server May not be availble"
Options: Windoes found a problem that cannot be repaired automatically

So i reset the adapters.... no change. The only thing i can do is restart the computer and everything works fine! This happens from a few hours to a few days, i can't seem to figure out what makes it happen. Sometimes im using it sometimes im not. Ive run spybot and antivirus ... turns up nothing. Firewalls are turned off... nothing.

Flushdns = Does not work

This only happens on the Vista Computer.

Ive eliminated Router problems, dns problems, computer problems... the only thing it can be is a vista problem?

Ideas?

I have the exact same problem. the exact same!! Except my "Machine 2" is a desktop. But I have all those same connection problems. It has to be a problem with windows vista. I just wish I knew how to fix it

I'm About to Install XP, I was browsing an hour ago and i clicked a donation link for paypal and.... page could not be displayed... is paypal down? nope! i hit back on my browser... NOTHING!

I hate rebooting for no reason.

Well, after researching. I may have found something that could fix it. It seems to be a problem with the Internet Connection sharing. This link shows some guy with the same problem and how he fixed it:

KB 937168 - After you configure Internet Connection Sharing in Windows Vista, the network connection stops working after one-to-two hours. - Aaron Tiensivu's Blog

And this link is the Hotfix page for the problem where you can download the patch for this problem from Microsoft. you have to wait a couple hours for them to email you the info on where to get the patch

The Knowledge Base (KB) Article You Requested Is Currently Not Available

Hope that helps some people.

Thanks so much anacozero, really helped me out!

I also have the same exact problem but my machine 2 is on visat 32 premium home edition and it has no problems!!!! Tried everything mentionned above. Have the computer since April 07 and notice the problem after a windows update on dec 21. All my network adapters are fine and updated. Had a 6 to 4 adapter issue with a yellow exclamation mark. Window message said could not upload the drivers. Looked everywhere for solutions!!!! wireless. lan and dialup doesn't work. Says limited connectivity. Please help
