I have an ongoing internet connection problem. Computer will be fine,then it drops the connection. When trying t repair it,I get the following message, There may be a problem with your DNS configuration. Windows failed to find the well known host www.microsoft.com using DNS.
The server may be down
It only happens with my desktop that I am running Vindows Vista Home Premium on.I also have a laptop running XP,that is fine,connection never drops. Desktop is wired to a D-Link DGL-4300 router. Anyone have any clues on what I can do to fix this? Most of the time,I just wait a very long time,and the connection is ok until it drops again.Thanks for the help.

 

I've had the same problem recently with my DNS servers. It's affecting all computers on my network vista, os x, iPhone, windows 7. It seems to be intermittent and only last a few minutes. There's nothing wrong with vista it something with the DNS servers which you have no control over. My DNS servers a 4.2.2.1 and 4.2.2.2 which are very popular DNS servers.

 

It's teh conficker

 

Can you test the laptop at the exact moment your desktop drops the connection to make sure its not the service? i know you've said the laptop never does drop but worth a shot to verify.

 

Tried it. Laptop connects no problem at all. It's driving me nuts already. Have no idea what to try next.

 

It might be crappy drivers, have you tried updating them. go to your OEMs site and see if they have newer drivers for your model PC.

i have the same issue...It's annoying....VERY annoying


And I keep getting stupid popups too. I think there is some kind of virus on my CPU, but everytime I scan, nothing (and I have AVG)

 

I have run McAfee and it scans fine...

Ok, I got everything figure out. Had to Disable TCP Auto-Tuning in Vista.

1. Open elevated command prompt with administrator’s privileges.
2. Type the following command and press Enter:

netsh interface tcp set global autotuning=disabled
If you ever need to turn this back on, here is how you do it.

Enable TCP Auto-Tuning

1. Open elevated command prompt with administrator’s privileges.
2. Type the following command and press Enter:

netsh interface tcp set global autotuning=normal
Connection has been great!

 

^ hah i was about to suggest that. had to do the same on my PC when i first went to vista. Still had to do it in 7 too.

although i'm using netsh interface tcp set global autotuning=restricted, rather than netsh interface tcp set global autotuning=disabled

 

where does one go to open elevated command prompt?

 

Mine does same thing drops wireless connection. comes in and out every so often. I'm also running Vista, But my old laptop aslo did same thing I also run two different routers and still the same thing happens. When I use an Ethernet everything is fine.

 

yea how do you get to it my connection keeps going in and out i thought i was the only one i have vista too.

 

hit the start button and type in cmd. the command prompt icon will appear, right click on that and choose run as administrator.

 

well i just did the cmd prompt thing now lets see if the signal drops again...

 

damn didn't work

 

Ok, I should not have opened my mouth that fast. Connection dropped again. I have to check with my ISP and see if there is anything goung on on their end.

 

What firmware version are you running on the router?

 

Just updated it, version 1.9

 

just updated it today? have you had the dropped connection since the FW update I guess is my question.

 

Yes it has dropped since I updated the firmware
