Windows 7: Download/Internet problem with Windows 7

Since I installed Windows 7 I noticed a strange problem- i can't download some files, no matter what browser/download client i'm using.

The download freezes at 90%-98% and won't finish. This is about random files (drivers, .doc, .pdf, ...etc) The problem is not in the files (i downloaded them using another internet connection on another computer, so they are not corrupted or something).
I also have problems opening some clips (maybe 5 out of 20 won't open).

The other problem is with World of Warcraft. When i enter the game, after 1 sec everything freezes, like my connection has stopped. If i am alone it is OK, but as soon as another player shows on the screens, this happens.

I am using a Broadband (PPPoe) connection. I called the ISP, but they said that everything on my connection is normal. There are other people using this ISp and windows 7, but they are not having such problems.

I thier different things- changing my LAN card, disabling IPv6, running programs as administrator... but none of them helped.



I hope that you can help me solve this issue.
Thanks

For a heads up.... people on the other end of the phone can only see their modem and back.... they could care less anything going to the ethernet cable going out of the cable/dsl modem.

I called up road runner and they said that everything was fine on their end. My connection was flawless when it came to the network. I went through hours of nothing....

then 5 hours later when i woke up... the internet just happen to be working fine... so just becareful from what they tell you, sometimes they just say that to get you off the phone.

I will consider this, but anyway, i want to post the ipconfig /all settings, so you can see if there is something unusual in them

Disable TCP/IP v6

just for the time being..

unplug the modem for 30 seconds...

and also we can do a dns flush as well

1. Click the Microsoft 7 Start logo in the bottom left corner of the screen
2. Click All Programs
3. Click Accessories
4. RIGHT-click on Command Prompt
5. Select Run As Administrator
6. In the command window type the following and then hit enter: ipconfig /flushdns
7. You will see the following confirmation:
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.

and reboot the computer

I have done all of this, without success.
And i don't have a modem, i have a cable plugged in my LAN card, and i use a username/password to connect

Yes but what is at the other end of the LAN card (aka your machine)?

It is connected to a router/switch (i don't know what) which is outside of the building where i live.

The others that you say are using th same ISP, are they you mates, who uses the same method of connection as you?

I find this weird

This should not give you internet access at all.

Neither will your ethernet, as your DNS servers cannot be that. And you don't have a DNS suffix?

If you can compare your ipconfigs with your mates, the difference will be telling.

The first one, named "optic" is the name of the broadband connection i created to connect to the internet. The second one mabe shows the LAN card (it shows "no internet access", but if i disable it, it says "cable unplugged".

The other clients of the ISP use the same method to connect. I will see if anyone can post their settings in the isp forum.
I will also try to enable dns suffix from the connection 's properties.

Can you disable the PPP and see if you can connect using ethernet?
