Why is my WAN/LAN connection stops working

Why is my WAN/Lan connection stops working. all streming ports (utorrent, internet TV or Radio) are open and works Ok! But it seems to me that 30 minutes of doing nothing (just listening), watch movie etc. shuts down idle ports for IE or firefox, mail etc. This problem occures When I'm going to use my Browser, read new e-mail then is connection offline. I have to reboot my network card to go online to Internet.
Realtek - Ethenet Diagnostic Utility shows no problem. I have latest driver updated " RTL8111C_LAN_V735222009_WIN7 "
Cant find any in the windows 7 BIG manual of 1083 pages.

Go to device manager and go to the properties of your wireless. Select the power management tab and uncheck the option that allows the computer to turn it off. Then go into power management and advanced power management and scroll down to where it says wireless adaptor settings and I think you disable anything that says turn off, lower power, etc.

I am on an xp computer right now so I can be more exact when I get home later. I can give you more if this doesn't seem to work for you

Also, disable PCI express power saving in the power options

Hi DustSailor, thank's for your sollutions.
- All power savings are inaktivated or disabled, both in normal and advanced settings!
- I have tryed to installed a second wire com card (also Realtek) and exactly the same problem occures.
- I tryed to have one at the time in single operation and also both in operation at the same time. The problem still occures....

Alright, its not good to connect both at the same time, choose one that you like best, and disconnect the other. Then uninstall all previous drivers and software for your wireless card (both for both cards if you installed both). Go to the maker's website and download their driver (to the card you chose). it should ask some questions and go through a whole setup. after that, the internet should work. If you still have trouble, go to control panel > Network and Internet > Network and Sharing Center > Manage wireless networks (on the left hand side). Then right click the device you see (Should only be one) and go to properties. Make sure the boxes "Connect automatically when this network is in range" and "Connect even if the network is not broadcasting its name (SSID)" are checked. Let me know if this does it for you.

All above has earlier been done!
PS! I have wire connection to my router!
With Win XP Pro this card works properly and in dual connections and with same settings in W7Pro, it fails.

Hmm, perhaps it is a compatibility issue then. Someone else may have to help you out as I'm all out of ideas. I've heard about installing drivers and setting them into windows xp compatibility mode in windows 7, but you may have to search google to find out how.

Hello again, this problem are strange! ASUS, Reltek, Microsoft TechNet, Win 7 Sweden forums has no sollution! It occures only in W7PRO 64bit.
The best workaround today are to use both comcard, and one at the time! When communictions goes down, disable that card and then enable next card and so on....
